Int into foreach that doesn't increment

Question

I'm creating a formulary with a lot of things into it and i've a simple problem with my foreach.

Here is my code :

    foreach($aDonnes['Grilles'][$iGrilleId] as $iCptGrille){
       $sHtml .='<tr><td class="grille">'.($sGrilleLib=$aDonnes['Grilles'][$iCptGrille][1]).'</tr></td>';
       $aDonnes['Domaines']=$oRolling->find_domaines($iCptGrille);
    if ($iCptGrille < $aDonnes['Grilles'].length) {
        $iCptGrille++;
    }

    // Several nested foreach

I've tried without the if condition, or anything and it still doesn't increment when I check the logs, It just do the same thing again and again.

If you've any questions feel free to ask.

NB : $iCptGrille is my int that doesn't increment and aDonnes is an array that has a lot of data into it, and in our case this is for each ID of my Table called "Grille" that i want to loop.

Answer 1

If you are checking a 2D array, I think the foreach input should be:

foreach($aDonnes['Grilles'] as $iCptGrille){...}

Also the counter name has the same name as the object item $iCptGrille, which doesn't make sense.

Also you can try initializing the counter by 0 before foreach block and remove 'if' statement if it's unnecessary.

For furthur investigations, you can use some kind of flag (for example echo 'entered'; ) inside the foreach block, to make sure it enters into the foreach block.

I hope it helps.

正如Answers_Seeker所说，“这是范围的问题：使用as关键字可以复制实际的数组元素”。
