Get foreach numeric index when keys are named - php

Question

This question is just for fun and out of curiosity.
Edit : My question is different than
How to find the foreach index
Because $key has already a non-numeric value in my case.
Without having a variable outside a foreach that is increment inside the foreach scope, as the usual $i, is there a way to get the index of an item when $key is already named ?
Exemples :
$myNumericIndexArray = ('foo', 'bar', 'go', 'habs');
foreach($myNumericIndexArray as $key => $value){
//Here $key will be 0 -> 1 -> 2 -> 3
}
Now, if I have :
$myNamedIndexArray = ('foo' => 'bar', 'go' => 'habs', 'CSGO_bestTeam' => 'fnatic');
foreach($myNamedIndexArray as $key => $value){
//Here $key will be foo -> go -> CSGO_bestTeam
}
Can I, without having to :
$i=0;
foreach($myNamedIndexArray as $key => $value){
//Here $key will be foo -> go -> CSGO_bestTeam
$i++;
}
access the index of a named array. Something declared in the foreach declaration like in a for or a status of $key ?
Have a good one.

Answer 1

If you really want index array of associative array than try this:
$myNamedIndexArray = ['foo' => 'bar', 'go' => 'habs', 'CSGO_bestTeam' => 'fnatic'];
$keys = array_keys($myNamedIndexArray);
foreach($myNamedIndexArray as $key => $value){
echo array_search($key, $keys);
}

Answer 2

I don't know why you would want to do an array_keys() and array_search() every loop iteration. Just build a reference array and you can still foreach() the original:
$positions = array_flip(array_keys($myNamedIndexArray));
foreach($myNamedIndexArray as $key => $value){
echo "{$key} => {$value} is position {$positions[$key]}\n";
}

Answer 3

Something like this :
<?php
$myNamedIndexArray = array('foo' => 'bar', 'go' => 'habs', 'CSGO_bestTeam' => 'fnatic');
$numericIndexArray = array_keys($myNamedIndexArray);
foreach($numericIndexArray as $key=>$value){
echo $key.'</br>'; //here key will be 0 1 2
echo $value. '</br>';
}

Answer 4

I'd try something like this:
<?php
$myNamedIndexedArray = ['foo' => 'bar', 'go' => 'habs', 'CSGO_bestTeam' => 'fnatic'];
$myNumberIndexedArray = array_keys($myNamedIndexedArray);
foreach($myNumberIndexedArray as $key => $value){
echo $key. " => " . $myNamedIndexedArray[$myNumberIndexedArray[$key]]."<br />";
}
?>
Adn the output will be:
0 => bar
1 => habs
2 => fnatic
