Array Sort and Foreach

[gorilla1]

I am trying to sort the records in a file, then index into the array, with the following code:

$data = file('xxx.txt');

$data = asort($data);

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

This code fails with this message:
Invalid argument supplied for foreach()

That makes it sound like the sort left me without an array??
Note that if I leave out the line with the sort in it, the code works fine.

The return type of asort() is void, so in your example $data is void rather than an array. Try to use

asort($data);

and tell us if that's helping in your situation.

Yes, thqt did the trick. Thanks, Mordred.
