json_encode get values foreach object

Question

Hello I can't figure out how to loop through this json encoded array and for each object, get all its values. I need each value as a variable for itself.

echo json_encode($formulars);

This is what i get when i echo it out

[{"project_name":"polle","type":"support","title":"vi","reason":"prover","solution":"igen","comments":"okay ","date_stamp":"2013-08-20 14:06:37","used_time":132},{"project_name":"dolla","type":"support","title":"lolol","reason":"skl","solution":"dskal","comments":"kflafda ","date_stamp":"2013-08-20 14:11:36","used_time":210},{"project_name":"polle","type":"fejl","title":"lol","reason":"aksdl","solution":"fdjks","comments":"djsks ","date_stamp":"2013-08-20 14:13:27","used_time":1230}]

I have tried this piece of code and I managed to get out the project_name from the first object and that's it:

foreach ($formulars as $current => $project_name) {
        $project_name['project_name'];

    }

So is there any way i can get all the variables for each object in my array instead of just the project_name?

Like this:

foreach ($formulars as $current){ 
    $projectName = $current['project_name'];
    $type = $current['type'];
    $reason = $current['reason'];

}

Thanks in advance

The "like this:" code seems sufficient. Why didn't it work? What happened? — mario

Oh god mario I actually didn't even test out the "like this" code I just typed it out fast. I just tried it and it worked. I feel so stupid hehe. Thank you though ! — Alex.M.K

Seems like you have an objects inside an array. So you will need to loop through the array and get each object. Just JSON_DECODE your encoded string like below.

Perhaps:

$data = json_decode($formulars,true);
/* Since it's only one object inside the array, you could just select element zero, but I wil loop*/

//You should now be able to do this
foreach ($data as $current){ 
    $projectName = $current['project_name'];
    $type = $current['type'];
    $reason = $current['reason'];

 }

The reason I loop is because there is a object inside an array(Javascript way I think).

I have tried to use json_decode but it wont let me. I get this message: Warning: json_decode() expects parameter 1 to be string, array given

@Alex.M.K Oh... Then it means you can skip the decoding step because it is no longer a json string. It's an array(probably decoded it somewhere). You can just skip to the foreach step. Or use element zero in this case. But rather loop through it.

Use json_decode to convert the json object to an array; then use foreach to loop through the array. That should work.

<?php
    $arr_json = json_decode($formulars);
    foreach($arr_json as $key => $value)
        //Code to perform required actions
?>

This should give you some ideas.

Use json_decode (with TRUE for getting an associative array)to convert your JSON object to an associative array. After that, you can use a foreach loop to traverse through your multidimensional array and print the required values.

Code:

$json = json_decode($string, true);

foreach ($json as $key => $value) {
  foreach($value as $key2 => $value2) {
    echo $value2."\n";
  }
}

Working Demo!
