How to find the foreach index?

Question

How to find the foreach index?

Is it likely to discover the foreach index?

in a for loop as follows:

for ($i = 0; $i < 10; ++$i) {

   echo $i . ' ';

}

$i will give you the list.

Do I need to utilize them for loop or is there some approach to get the index in the foreach loop?

foreach($array as $key=>$value) {

    // do stuff

}

$key is the index of each $array element

A foreach will give you your index in the form of your $key value, so such a hack shouldn't be necessary.

e.g., in a foreach



$index = 0;

foreach($data as $key=>$val) {

    // Use $key as an index, or...



    // ... manage the index this way..

    echo "Index is $index\n";

    $index++;

}
