passing PHP objects to javascript [duplicate]

I need to pass a php variable to a jquery function. the php variable is an array of unknown size. is there a way to pass each member of the array to be processed individually by the function?
I Guess you should use JSON to pass the php variable to jquery. its the easiest way to do that.
You can use JSON to print the array and parse that to receive a JS object.
I assume you use AJAX (directly printing into the javascript source is possible but ill-advised).
Your php script needs to print output directly:
print_r(json_encode($data_array));
And on the receiving end use $.parseJSON:
var data_array = $.parseJSON(ajax_result);

How to loop through PHP object with dynamic keys [duplicate]

Closed 5 years ago.
if i solve this i will have my desired result for any expert this will take few minutes to guess and i am stuck in this from last 2 hours searching and googling but couldn't found the one i want. Okay so here is the thing ...
I am sending data through ajax to my php by doing JSON.stringify and receving that that to my php in the form of this
{"0":["BE","test","test","1993"],"1":["HSSC","test","test","1995"]}
All i want to do is to get the values and insert them to the separate variables.
You need to use json_decode to convert the string to array. You can pass the second parameter to this method to convert this to array instead of object. Then you can retrieve the data like
$string = '{"0":["BE","test","test","1993"],"1":["HSSC","test","test","1995"]}';
$array = json_decode($string, true);
print_r($array[0][0]);
Here's the example of it https://repl.it/HhI8/1

I need to extract the name of the png which in this array is: 56f26f5862fb85.90873638.png. The value is the following context:
i:204;s:27:"56f26f5862fb85.90873638.png";
It would be really convenient if I could look the name after the 204 which is always fixec.
Any guidance or suggestion as for how to solve it is much appreciated.
That is a serialized PHP value, created using the serialize() function.
You can unserialize it using the unserialize() function:
$data = unserialize('a:2:{s:18:"_gravity [...] tal";s:5:"Total";}}');

How can I convert this to an array in PHP?
&height=0&weight=2&width=10
I'm passing a data from a jquery function using .serialize() to a PHP function.
Any ideas?
Can be done within one line. :)
parse_str('&height=0&weight=2&width=10', $array);
print_r($array);
Depending on what type of request you are performing, it may already be in an array. Have a look at the PHP documentation on $_GET and $_POST global variables.
To view the contents of said array. You can use the function print_r() which will show you the contents of the array.
print_r($_GET)
print_r($_POST)
Access individual items in the array by the item's key. For example:
echo $_POST['height'];

Access a JavaScript variable from PHP
I have a Javascript function that takes in one variable. The function has some php code inside it. I want to use this variable inside the php section of the function. I couldn't get it to work. How is it done?
The issue is that your PHP code is being rendered on the server before being served to the client. I would recommend either converting the PHP code into Javascript code or creating an AJAX call to the PHP function.
Start reading about AJAX! You will likely need to rewrite some of the code you have written but what you are attempting to accomplish is not really possible otherwise.
try with it
<script>
var whatever = "<?php echo $phpVar ?>";
</script>
