What the heck is wrong with this code?

foreach($data as $info) {
$info=explode("=",$info);
$post[$info[0]]=$info[1];
}

Hmm, letz see who cracks this first!

hmmm, dunno but it seems there is an issue with converting the string to an array like that; it may give you a fatal error

Actually, there is nothing wrong with the code, the only time you cannot do this kinda thing is:

foreach($data as $info) {
$info=explode("=",$info);
$data[$info[0]]=$info[1];
}

Notice that - i only replaced $post with $data =>
This will result into a logical error:

Reason:
When foreach starts, a copy of the original array is kept inside its 'pocket of the function',

so that while the loop runs, it runs from the copy,
your own attempt to make changes to the same array 'data' will not do anything,

because at the end of the foreach, the original $data will the overwritten with the one inside the pocket.
