PHP Get key value - php

Question

I am trying to get the key from an array to make divs become:
<div id="item">
<div id="item-1">
<div id="item-2">
<div id="item-3">
My array code is:
$a = $something['no'];
$array = array_fill(0, $a, 'value');
foreach($array as $key => $value){
if($key == '0') {
$x = 'item';
} else {
$x = 'item-'.$key;
}
$insert .= '<div id="'.$x.'">';
// content here
$insert .= '</div>';
}
$key isn't being sent, I tried echoing $key and got no return, is there something I am missing?
Print_r on the array shows:
Array ( [0] => value [1] => value [2] => value )
Fixed Code:
$a = $something['no'];
$array = array_fill(0, $a, 'value');
foreach($array as $key => $value){
if($key == '0') {
$x = 'item';
} else {
$x = 'item-'.$key;
}
$insert .= '<div id="'.$insert = $x.'">';
// content here
$insert .= '</div>';
}

You could minimize your code with a for loop:
$something['no'] = 4;
$html = '';
for ($i = 0; $i < $something['no']; $i++) {
$x = !$i ? '' : "-{$i}";
$content = "woof woof";
$html .= "<div id=\"item{$x}\">".$content."</div>\n";
}
print_r($html);
Saves on assigning a variable and running a separate process to fill an array with numbers which you could just add up to anyway
