Using IF *within* Foreach?

[stephdumais]

I had already guessed that simply using the IF (or switch) function within a foreach statement wouldn't work, but I don't know any alternatives. Here is what I want to do:

I have a text files which are used as arrays (they contain two values per line...let's say logins and passwords for the sake of explaining this). Since I call upon different arrays, I want my script to look up the requested array and associate a called value (i.e: login) with it's match (i.e: password). To do this, I figured I would have an if (or Switch) expression dynamicaly generated by the chosen array. Here is what it looks like, logicaly:

$array=file("file1.txt");
foreach ($array as $line)
if (ereg("^{([\t])\t+([\t])$",} trim($line), $reOut)) {

                  if ($page = $reOut[2]){
	$password = $reOut[1];
	                  }

}

If the above intention is clear, can anyone help me find a working version of the above?
Thanks

(please note that this has nothing to do with logins and passwords, it was just for the sake of an example)

if's work fine within foreach statements.

$page = $reOut[2] should be $page == $reOut[2].

Don't know if your ereg is correct or not.

D'oh! All this for nothing. You pointed out the "==" instead of "=" and that was all that fixed it. Thanks!
