Use two columns from a 2d array to form an associative array [duplicate]

Question

I have an array like this :

array(3) {
  [0]=>
  array(2) {
    [0]=>
    string(6) "action"
    [1]=>
    string(5) "depot"
  }
  [1]=>
  array(2) {
    [0]=>
    string(9) "Demandeur"
    [1]=>
    string(11) "Particulier"
  }
  [2]=>
  array(2) {
    [0]=>
    string(3) "Nom"
    [1]=>
    string(6) "Cheval"
  }

But I want an associative array, to access it like this : $_REQUEST['Nom'] and have in return 'Cheval' etc...

The first array is actually an object, created with jQuery and here is his construction :

jQuery('input:submit').click(function() {
    var itemMetaArray = {};
    jQuery('.frm_pro_form :input:not(:hidden, :submit)').each(function() {
        if(jQuery('#field_demande').val() != undefined){
            itemMetaArray['action'] = jQuery('#field_demande').val();
        } 
        else itemMetaArray['action'] = jQuery('#field_demande2').val();
        var label = jQuery(this).closest('.frm_form_field').find('.frm_primary_label').text().trim();
        if(jQuery(this).attr('name').indexOf("file") == -1 ) {
            itemMetaArray[label] = jQuery(this).val();
        }else{
              var fileName = jQuery(this).attr('name');
              fileName = fileName.substring(0,fileName.length-2);
              itemMetaArray[label] = fileName;
        }
});

After this, I do some parsing in PHP :

$dataInfo = explode(",",$_POST['dataInfo']);
for ($i = 0; $i < count($dataInfo); ++$i){
    $tmpWithoutBrackets[$i] = trim($dataInfo[$i],"{..}");
    $tmpWithoutColon[$i] = explode(":",$tmpWithoutBrackets[$i]);
    for($j = 0; $j < (count($tmpWithoutColon) + 1); ++$j){
        $arrayFinal[$i][$j] = trim($tmpWithoutColon[$i][$j],"\"");
    }
    $arrayFinal[$i] = array_diff($arrayFinal[$i],array(""));
}

$arrayFinal is the same array as arrayInfo

Thanks in advance for your help

Show us how you create the first array. That is where your issue is, and that is where the fix should be applied — RiggsFolly

You need to modify your array like this:

$test = array('arrayInfo' => array(array('Nom','Cheval'),array('Prenom','Nathan'),array('Adresse postale','4 impasse Molinas')),'arrayFile' => array(array ('application/pdf','3a514fdbd3ca2af35bf8e5b9c3c80d17','JVBERi0xLjUNCiW1tbW1DQoxIDAgb2JqDQo8PC9UeXBlL0NhdGFsb2cvUGFnZXMgMiAwIFIvTGFuZyhmci1GUikgL1N0cnVjdFRyZWVSb290IDI2IDAgUi9NYXJrSW5mbzw8L01hcmtlZCB0cnVlPj4vTWV0')));

$result = array();
foreach($test as $k=>$t){
    $count = 0;
    $_key = '';
    $_value = '';
    foreach($t as $f){
        foreach($f as $final){
            $count++;
            if($count%2!==0){
                $_key = $final;
            }
            else{
                $_value = $final;
            }
            if($_value!==''){
                $result[$k][$_key] = $_value;
                $_value = '';
            }
        }
    }
}

echo $result['arrayInfo']['Nom'];//Cheval

For your modified question, answer will be a little changed ofcourse:

    $test = array(array('Nom','Cheval'),array('Prenom','Nathan'),array('Adresse postale','4 impasse Molinas'));

$result = array();
foreach($test as $k=>$t){
    $count = 0;
    $_key = '';
    $_value = '';
    foreach($t as $final){
        $count++;
        if($count%2!==0){
            $_key = $final;
        }
        else{
            $_value = $final;
        }
        if($_value!==''){
            $result[$_key] = $_value;
            $_value = '';
        }
    }
}
var_dump($result);
echo $result['Nom'];//Cheval

I hope it helps

No problems, just take care that your [arrayFile][0] has three values, while it should have only two as [arrayInfo]. Possible typo. Happy Coding!
I update my first post, because it wasn't clear after reflexion.. Actually I need to do the same as your answer, but not on the same array. I try to modify your code, but without success..
@Nathan30, I have updated my answer to suit your current question.
This is not exactly the same array as me. Mine is more like : "array(array("nom","cheval"))" so I have an error at the third foreach...
