Good evening or morning everyone..
Is there any way to understand this:
$array = ('element 1','element 2','element 3');
while($x=each($array)){
echo $x.' Value:'.$x;
}
I mean where did the 'key' and 'value' come from although they're not defined in the file at all??

Sorry, I've forgotten to enclose the code with coding tags.

I think php already defined it.. although I couldnt find that in php manual

I would use foreach in this case

I agree with evstevemd.

foreach ($array as $key => $value) {
  echo 'The key is '.$key.' and the value is '.$value; 
 }

$key and $value are created as part of the foreach statement.

See the manual page for each. It's in the third section (return values).

Thank you. I've found the solution.

Thank you, but that's not my question at all.

Well the answer I provided is the same as the answer to your question. Perhaps I assumed you'd make the link. So, to be explicit:

'key' and 'value' are keys of the array $x which are created as part of the each() function.
