json_decode to array

Question

I am trying to decode a JSON string into an array but i get the following error.

Fatal error: Cannot use object of type stdClass as array in C:\\w

Answer 1

json_decode($data, true); // Returns data in array format 

json_decode($data); // Returns collections 

So, If want an array than you can pass the second argument as 'true' in json_decode function.

Answer 2

in PHP json_decode convert json data into PHP associated array
For Ex: $php-array= json_decode($json-data, true); print_r($php-array);

Answer 3

I hope this will help you

$json_ps = '{"courseList":[  
            {"course":"1", "course_data1":"Computer Systems(Networks)"},  
            {"course":"2", "course_data2":"Audio and Music Technology"},  
            {"course":"3", "course_data3":"MBA Digital Marketing"}  
        ]}';

Use Json decode function

$json_pss = json_decode($json_ps, true);

Looping over JSON array in php

foreach($json_pss['courseList'] as $pss_json)
{

    echo '<br>' .$course_data1 = $pss_json['course_data1']; exit; 

}

Result: Computer Systems(Networks)

Answer 6

json_decode support second argument, when it set to TRUE it will return an Array instead of stdClass Object. Check the Manual page of json_decode function to see all the supported arguments and its details.

For example try this:

$json_string = 'http://www.example.com/jsondata.json';
$jsondata = file_get_contents($json_string);
$obj = json_decode($jsondata, TRUE); // Set second argument as TRUE
print_r($obj['Result']); // Now this will works!
