foreach operation assigns value to key ??

I made a mistake while using foreach on an array but the code still worked.

Array ( [0] => u_fname [1] => u_showname )

I then did

foreach ($cfentarr as $k => $tx ) {
		if($k=='u_fname')$memname=$row2[$tx];
	}

$row2 is a mysql array...
Spot my mistake in the foreach - $k only ever equals the array index number - it never equals "u_fname".

BUT I have no problem getting $memname set here - but it shouldn't be !!

I've corrected my code but above behaviour is weird
Or am I misunderstanding what => does on indexed arrays?

Is the 'Array (..)' output showing the contents of $cfentarr?

If so, then no, $memname will never have been defined by the code you posted. If it was, then it must have come from some place else.

Yes array output is showing $cfentarr
Thanks - at least that confirms it must be an error in my code somewhere else
I just can't see it right now.

Are any of the variables involved actually references to others? That can cause wacky-looking interactions.

<?php

$array = array('i'=>'b', 'ii'=>'c');

$k = &$foo;

$foo = 'spangler!';

foreach($array as $k=>$v)
{
	if($k == 'b')
		$foo = $v;
}

echo $foo;

Hmm, that's something I've not come across - scratches head at result of that sample..

I don't think there are any references I've set - it's code I did over a year ago and I'm making some updates - nothing to do with this part - but I spotted the mistake and couldn't figure out how it still did what it was meant to do...
Sounds like that could be it - I'll look through it again tomorrow

Thanks .. I think..
