PHP push associative array in normal array

Question

I have to push an associative array in a normal array (not to convert).
Example (NO CODE):

project = {}
element["title"] = "My title"
element["description"] = "My description"

is there a way to have this

echo $project->title;
//or
echo $project[0]["title"]

? I'v tried this, but server says: ERROR 500

    $i = 0;
    $projects = {};
    foreach($projectsElements as $element) {
        while($i <= $nRowsForProject) {
            $idSection = $element->idSection;
            if($idSection == 1) $elements["".$element->internalDescription.""] = $element->text;
            else if($idSection == 2) $elements["".$element->internalDescription.""] = $element->text;
            else if($idSection == 3) $elements["".$element->internalDescription.""] = $element->text;
            $i++;
        }
        array_push($projects,$elements);
        $i=0;
    }

You confuse things: an object is something different than an array. The -> operator references a property inside an object, but that is not possible in a declarative manner. Also creating an object is not possible by a simple $projects = {}; as you attempt to, that is a syntax error (your error 500). Instead you typically have to implement a class of which you then can instantiate an object. — arkascha

$projects = {}; is not valid php.

If you want to initialize an empty array (associative or numeric, that does not matter), you need:

$projects = [];

or on older php versions:

$projects = array();

Also note that you need to do the same to your $elements array at the beginning of each iteration otherwise it will grow on every iteration. Assuming that the descriptions are not all the same...

foreach($projectsElements as $element) {
    $elements = [];
    while($i <= $nRowsForProject) {
        ...

And your while loop does not seem to make a lot of sense: You are not using the $i variable in your loop so are just doing the same assignments on each iteration.

$projects = []; // declare empty array
foreach($projectsElements as $element) {
  $projects []= $element; // push $element into $projects array
}

$i = 0;
$projects = array();
foreach($projectsElements as $element) {
    while($i <= $nRowsForProject) {
    $elements = array();
        $idSection = $element->idSection;
        if($idSection == 1) $elements["".$element->internalDescription.""] = $element->text;
        else if($idSection == 2) $elements["".$element->internalDescription.""] = $element->text;
        else if($idSection == 3) $elements["".$element->internalDescription.""] = $element->text;
        $i++;
    }
    array_push($projects,$elements);
    $i=0;
}
