Converting PHP array to JS array in PHP itself

Hey just a small thing I am stuck on.
I do have the structure ready for the JS array but I need to assign it to a variable like
var data ={ Php array }
Here is the structure of my php array: https://imgur.com/a/LPbCqEu This is just a part of the array.
My code looks like this:
$csvfile = 'Property_CSVTruncated.csv';
$handle = fopen($csvfile, 'r');
$jsData = array(
'properties' =>array()
);
$header = NULL;
while (($row = fgetcsv($handle, 1000000, ',')) !== FALSE) {
$i = 0;
if (!$header) {
$header = $row;
} else {
$data = array_combine($header, $row);
$fields = array(
'_id' => $data['C4021040'],
'index' => $i,
'price' => $data['123'],
'picture' => "https://ihatetomatoes.net/demos/_rw/01-real-estate/tn_property01.jpg",
'city' => "Calgary",
'MLS# ' => $data['C4021040'],
'address' => $data['6 ASPEN RIDGE LN SW'],
'latitude' => $data['51.045681'],
'longitude' => $data['-114.191544'],
'Bed' => $data['123'],
'Bath' => $data['123'],
'capSpaces' => $data['T3H 5H9'],
);
array_push($jsData['properties'], $fields);
}
$i++;
}
fclose($handle);
$str = "const data = ";
print($str);
header('Content-type: application/json');
json_encode($jsData, JSON_NUMERIC_CHECK);
$jsonFile = fopen('csvTojs.js', 'w');
fwrite($jsonFile, json_encode($jsData));
fclose($jsonFile);
So basically I need that string 'var data = ' and then prints the array.
Anyway to do that in php itself?
Thanks

in server, echo json_encode($phpArray) and exit;
in callback of ajax or init js variable, parse json to array with JSON.parse('jsonString');

Use json_encode()
<script>
var data = <?php echo json_encode($jsData, JSON_PRETTY_PRINT); ?>
</script>
Or in your case:
header('Content-Type: application/json');
echo json_encode($jsData);
exit;

Convert PHP array to JS array (ISO 8859-1 characters)

I can't get it to work despite all the sources. I try the following :
<?php
$list_array = array();
foreach ($this->resultatTypeMail as $mailType) {
$nom = $mailType->getNom();
$objet = $mailType->getObjet();
$list_array[] = array(
'Name' => $nom,
'Object' => $objet,
);
echo "<script type='text/javascript'>alert('$nom');</script>"; // this is OK
echo "<script type='text/javascript'>alert('$objet');</script>"; // this is OK
}
?>
<script type="text/javascript">
var js_array = [<?php echo json_encode( $list_array ); ?>];
alert(js_array[0]); // This returns undefined
</script>
I get satisfying results on $nom and $objet when I alert them.
Problem :
js_array[0] returns undefined
Note that I'm not in UTF-8. I'm not sure it's relevant though.
EDIT : A big picture of my goal is to get an array of custom php objet to be usable in JS.

Just remove the [] from var js_array = line and it will work:
wrong:
var js_array = [<?php echo json_encode( array_values($list_array) ); ?>];
right:
var js_array = <?php echo json_encode( array_values($list_array) ); ?>;
Working code:
<?php
class MailType {
function __construct($n, $o) {
$this->nom = $n;
$this->objet = $o;
}
private $nom;
private $objet;
public function getNom() {
return $this->nom;
}
public function getObjet() {
return $this->objet;
}
}
$list_array = array();
$resultatTypeMail = array(new MailType('John', 'obj1'), new MailType('Mary', 'obj2'));
foreach ($resultatTypeMail as $mailType) {
$nom = $mailType->getNom();
$objet = $mailType->getObjet();
$list_array[] = array(
'Name' => $nom,
'Object' => $objet,
);
//echo "<script type='text/javascript'>alert('$nom');</script>"; // this is OK
//echo "<script type='text/javascript'>alert('$objet');</script>"; // this is OK
}
?>
<script type="text/javascript">
var js_array = <?php echo json_encode( $list_array ) ?>;
alert(js_array[0].Name); // This returns John
</script>

In PHP an array that has string keys gets converted to an object when parsed with json_encode.
You could either use array_keys to force the creation of an array, or use the object notation in your javascript
<?php
$list_array = array();
foreach ($this->resultatTypeMail as $mailType) {
$nom = $mailType->getNom();
$objet = $mailType->getObjet();
$list_array[] = array(
'Name' => $nom,
'Object' => $objet,
);
echo "<script type='text/javascript'>alert('$nom');</script>"; // this is OK
echo "<script type='text/javascript'>alert('$objet');</script>"; // this is OK
}
<script type="text/javascript">
var js_array = [<?php echo json_encode( array_values($list_array) ); ?>];
alert(js_array[0]);
</script>
Or
<?php
$list_array = array();
foreach ($this->resultatTypeMail as $mailType) {
$nom = $mailType->getNom();
$objet = $mailType->getObjet();
$list_array[] = array(
'Name' => $nom,
'Object' => $objet,
);
echo "<script type='text/javascript'>alert('$nom');</script>"; // this is OK
echo "<script type='text/javascript'>alert('$objet');</script>"; // this is OK
}
<script type="text/javascript">
var js_array = [<?php echo json_encode( array_values($list_array) ); ?>];
alert(js_array.Name);
</script>

I think you have multiple issues: you're missing the ; after the json_encode() line (which is not actually required); you're surrounding the result of json_encode() with brackets (which should work but I expect it's not what you want); and the most important, you're missing the closing PHP ?> tag before printing the JS...
This works for me:
<?php
// your PHP code here...
?>
<script type="text/javascript">
var js_array = <?php echo json_encode($list_array); ?>;
alert(js_array[0]); // This works for me!
</script>
It looks like the issue may be in the encoding as you say - it seems that json_encode only works with UTF-8! From the json_encode() docs:
All string data must be UTF-8 encoded.
So I think you'll have to convert your strings to UTF-8 before putting them into the array, something like:
$list_array[] = array(
'Name' => utf8_encode($nom),
'Object' => utf8_encode($objet),
);
I think just that should work - otherwise you can try this from the comments in the same json_encode() docs; or this other question to get more ideas...

How can i add Dynamic Json data into a Mysql Database.

How can i add JSON Data into a Database? i have a script there is generating automatic updated JSON Data. i read in a book that i should use a methode called
JSON_decode
I Think i should have to do something like, put The value into The tables for each value. Then try to use The methode JSON_decode and then make a loop foreach. but i am not sure about this. what is the best way, and can you tell me what to do in my case or maby show a example?
Here is the data located:
http://csgo.nssgaming.com/api.php
The current script:
<?php
require_once ('simple_html_dom.php');
$html = #file_get_html('http://csgolounge.com/');
$output = array();
if(!$html) exit(json_encode(array("error" => "Unable to connect to CSGOLounge")));
// Source: http://php.net/manual/en/function.strip-tags.php#86964
function strip_tags_content($text, $tags = '', $invert = FALSE) {
preg_match_all('/<(.+?)[\s]*\/?[\s]*>/si', trim($tags), $tags);
$tags = array_unique($tags[1]);
if(is_array($tags) AND count($tags) > 0) {

PHP json to google chart api

I'm having trouble parsing my php generated json array to a google chart. I have included Jquery, but some how i can't figure out how to parse my json data. I run a MySQL query to retrieve data from the database. Then i encode the query result with php json_encode.
I use ajax to get the json data from my php file.
getData.php:
<?php
function get_meta_values( $key, $type = 'workout', $status = 'publish' ) {
global $wpdb;
$user_ID = get_current_user_id();
if ( empty( $key ) )
return;
$r = $wpdb->get_results(
$wpdb->prepare( "
SELECT pm.meta_value, p.post_date FROM {$wpdb->postmeta} pm
LEFT JOIN {$wpdb->posts} p ON p.ID = pm.post_id
INNER JOIN $wpdb->term_relationships
ON (p.ID = $wpdb->term_relationships.object_id)
INNER JOIN $wpdb->term_taxonomy
ON ($wpdb->term_relationships.term_taxonomy_id = $wpdb->term_taxonomy.term_taxonomy_id)
WHERE pm.meta_key = '%s'
AND $wpdb->term_taxonomy.taxonomy = 'category'
AND $wpdb->term_taxonomy.term_id IN (4)
AND p.post_status = '%s'
AND p.post_type = '%s'
AND p.post_author = $user_ID
ORDER BY pm.meta_value DESC ",
$key,
$status,
$type));
if ( $r ) {
$user_ids = wp_list_pluck( $r, 'post_date' );
cache_users( $user_ids );
}
return $r;
}
$workout_history = get_meta_values( '1_rep', 'workout' );
echo json_encode($workout_history);
?>
The page that holds the chart:
<script type="text/javascript" src="https://www.google.com/jsapi"></script>
<script type="text/javascript">
google.load("visualization", "1", { packages: ["corechart"] });
google.setOnLoadCallback(drawChart);
function drawChart() {
var jsonData = $.ajax({
url: "http://localhost:41175/wp-content/themes/wordpress-bootstrap-master/getData.php",
dataType: "json",
async: false
}).responseText;
var obj = window.JSON.stringify(jsonData);
var data = google.visualization.arrayToDataTable(obj);
var options = {
title: 'Test'
};
var chart = new google.visualization.LineChart(
document.getElementById('chart_div'));
chart.draw(data, options);
}
</script>
When i try to echo my json file it looks like this:
[
{
"meta_value":"999",
"post_date":"2014-04-12 18:21:51"
},
{
"meta_value":"1",
"post_date":"2014-04-12 18:58:20"
}
]
Any suggestions to what i am doing wrong?

https://developers.google.com/chart/interactive/docs/reference#google.visualization.arraytodatatable
Seems that your JSON dataset is incorrect for use with that method. It should be (in javascript):
var data = [
['metavalue', 'post_date'],
['999', '2014-04-12 18:21:51'],
['1', '2014-04-12 18:58:20']
]
which in JSON equals to:
[["metavalue","post_date"],["999","2014-04-12 18:21:51"],["1","2014-04-12 18:58:20"]]
As I have no clue where $workout_history is coming from I can't help you out with how get to that.

Your object graph is incorrect before you return $r do this:
$results = array();
$result[] = array_values($r);
return $result;
alternatively you can build an your array of array like this:
$results = array();
$result[] = array($r['message_type'], $r['post_date']);
return $result;

AJAX POST request is failing

Apologies for the generic title.
Essentially, when the script runs 'error' is alerted as per the jQuery below. I have a feeling this is being caused by the structuring of my JSON, but I'm not sure how I should change it.
The general idea is that there are several individual items, each with their own attributes: product_url, shop_name, photo_url, was_price and now_price.
Here's my AJAX request:
$.ajax(
{
url : 'http://www.comfyshoulderrest.com/shopaholic/rss/asos_f_uk.php?id=1',
type : 'POST',
data : 'data',
dataType : 'json',
success : function (result)
{
var result = result['product_url'];
$('#container').append(result);
},
error : function ()
{
alert("error");
}
})
Here's the PHP that generates the JSON:
<?php
function scrape($list_url, $shop_name, $photo_location, $photo_url_root, $product_location, $product_url_root, $was_price_location, $now_price_location, $gender, $country)
{
header("Access-Control-Allow-Origin: *");
$html = file_get_contents($list_url);
$doc = new DOMDocument();
libxml_use_internal_errors(TRUE);
if(!empty($html))
{
$doc->loadHTML($html);
libxml_clear_errors(); // remove errors for yucky html
$xpath = new DOMXPath($doc);
/* FIND LINK TO PRODUCT PAGE */
$products = array();
$row = $xpath->query($product_location);
/* Create an array containing products */
if ($row->length > 0)
{
foreach ($row as $location)
{
$product_urls[] = $product_url_root . $location->getAttribute('href');
}
}
$imgs = $xpath->query($photo_location);
/* Create an array containing the image links */
if ($imgs->length > 0)
{
foreach ($imgs as $img)
{
$photo_url[] = $photo_url_root . $img->getAttribute('src');
}
}
$was = $xpath->query($was_price_location);
/* Create an array containing the was price */
if ($was->length > 0)
{
foreach ($was as $price)
{
$stripped = preg_replace("/[^0-9,.]/", "", $price->nodeValue);
$was_price[] = "£".$stripped;
}
}
$now = $xpath->query($now_price_location);
/* Create an array containing the sale price */
if ($now->length > 0)
{
foreach ($now as $price)
{
$stripped = preg_replace("/[^0-9,.]/", "", $price->nodeValue);
$now_price[] = "£".$stripped;
}
}
$result = array();
/* Create an associative array containing all the above values */
foreach ($product_urls as $i => $product_url)
{
$result = array(
'product_url' => $product_url,
'shop_name' => $shop_name,
'photo_url' => $photo_url[$i],
'was_price' => $was_price[$i],
'now_price' => $now_price[$i]
);
echo json_encode($result);
}
}
else
{
echo "this is empty";
}
}
/* CONNECT TO DATABASE */
$dbhost = "xxx";
$dbname = "xxx";
$dbuser = "xxx";
$dbpass = "xxx";
$con = mysqli_connect("$dbhost", "$dbuser", "$dbpass", "$dbname");
if (mysqli_connect_errno())
{
echo "Failed to connect to MySQL: " . mysqli_connect_error();
}
$id = $_GET['id'];
/* GET FIELDS FROM DATABASE */
$result = mysqli_query($con, "SELECT * FROM scrape WHERE id = '$id'");
while($row = mysqli_fetch_array($result))
{
$list_url = $row['list_url'];
$shop_name = $row['shop_name'];
$photo_location = $row['photo_location'];
$photo_url_root = $row['photo_url_root'];
$product_location = $row['product_location'];
$product_url_root = $row['product_url_root'];
$was_price_location = $row['was_price_location'];
$now_price_location = $row['now_price_location'];
$gender = $row['gender'];
$country = $row['country'];
}
scrape($list_url, $shop_name, $photo_location, $photo_url_root, $product_location, $product_url_root, $was_price_location, $now_price_location, $gender, $country);
mysqli_close($con);
?>
The script works fine with this much simpler JSON:
{"ajax":"Hello world!","advert":null}

You are looping over an array and generating a JSON text each time you go around it.
If you concatenate two (or more) JSON texts, you do not have valid JSON.
Build a data structure inside the loop.
json_encode that data structure after the loop.

If i have to guess you are echoing multiple json strings which is invalid. Here is how it should work:
$result = array();
/* Create an associative array containing all the above values */
foreach ($product_urls as $i => $product_url)
{
// Append value to array
$result[] = array(
'product_url' => $product_url,
'shop_name' => $shop_name,
'photo_url' => $photo_url[$i],
'was_price' => $was_price[$i],
'now_price' => $now_price[$i]
);
}
echo json_encode($result);
In this example I am echoing the final results only once.

You are sending post request but not sending post data using data
$.ajax(
{
url : 'http://www.comfyshoulderrest.com/shopaholic/rss/asos_f_uk.php?id=1',
type : 'POST',
data : {anything:"anything"}, // this line is mistaken
dataType : 'json',
success : function (result)
{
var result = result['product_url'];
$('#container').append(result);
},
error : function ()
{
alert("error");
}
})
