convert std object array to simple php array

Question

my code so far

<?php
foreach($sub_category as $row2){

    $url = 'https://myurl.com';  
    $ch = curl_init();
    curl_setopt($ch, CURLOPT_AUTOREFERER, TRUE);
    curl_setopt($ch, CURLOPT_HEADER, 0);
    curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
    curl_setopt($ch, CURLOPT_URL, $url);
    curl_setopt($ch, CURLOPT_FOLLOWLOCATION, TRUE);  
    curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, 3);     
    curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, FALSE);
    $data = curl_exec($ch);
    curl_close($ch);
   
    echo $name." data = "."<pre>"; print_r($data);
}


?>

This is $data output

Array
(
    [0] => stdClass Object
        (
            [course_title] => 60+ Space Facts To Get An A In Astronomy
            [description] =>  60+ Space Facts To Get An "A" In Astronomy
            [image] => pexels-pixabay-39896_20210220014840929292735.jpg
            
        )

    [1] => stdClass Object
        (
            
            [course_title] => Learn Chinese
            [description] => Learn Chinese
            [image] => Chinoabc_20211227114307692406780.png
            
        )
 )

I want to convert it to look like below

Array
        (
            [0] => array
                (
                    [course_title] => 60+ Space Facts To Get An A In Astronomy
                    [description] =>  60+ Space Facts To Get An "A" In Astronomy
                    [image] => pexels-pixabay-39896_20210220014840929292735.jpg
                    
                )
        
            [1] => array
                (
                    
                    [course_title] => Learn Chinese
                    [description] => Learn Chinese
                    [image] => Chinoabc_20211227114307692406780.png
                    
                )
         )

i have tried many answers from here converting array of objects to simple array but it's not working for me

i have tried many answers from already posted questions. my problem is different than any other relevant question posted here

When you enable CURLOPT_RETURNTRANSFER then curl_exec() returns a string. Unless I'm missing something, $data is not an array of objects, it's just a text that happens to contain a PHP variable dump for some reason. It may be more obvious if you replace print_r() with var_dump(). — Álvaro González

Are you sure you didn't write $data = json_decode(curl_exec($ch));? — Barmar

APIs don't usually return print_r() output, they usually return JSON. — Barmar

You can use the (array) type cast to convert an object to an equivalent associative array.

$data = array_map(function($x) { return (array)$x; }, $data);

If the original array of objects came from using json_decode(), you can tell it to return associative arrays instead of objects by giving it a true second argument.

$data = json_decode($data, true);

$array is your array.

I've updated the answer to use your variable.

good finding you were correct the data was not json object that's why not working as array but simple string now in source i use $data =json_encode($data,true); than used your $data = json_decode($data, true); and yes done now i have string as an array ready to use thumbs up :)
