!not operator doesn't seem to be doing what i expect

Hi i have a very simple for each statment spitting out some stuff on my page. One of the array id's is "username" and i'm after it missing that one out but doing this rest

I thought this would work
[code]
foreach ($details as $key => $value)
{
if (!(($i + 1)% 2))
{
if (!$key == 'username')
{
$head = explode("_", $key);
echo "<span class='textFieldReg'>".ucfirst($head[0]." ".$head[1]).":</span> \n";
echo "<input type='text' name='$key' value='$value' class='myInputReg'/><br />\n";
}
}
$i++;
}
[/code]
it's the "!$key == 'username'" bit i mean if i take away the "!" is just gives me the username field but if i put in the "!" it doesn't give me anything.

Can't quite understand.

It should be...

[code=php:0]if ($key != 'username'){[/code]

Not ...

[code=php:0]if (!$key == 'username'){[/code]

Or... we could really throw a monkey wrench in it and check it this way:
[code]
<?php
if (!($key == 'username'))
?>
[/code]

LOL... yes, same here. I was basically just trying to point out that all the '!' operator does is negates the associated value. So, without the parenthetical, it's trying to negate $key alone. If you simply add the parenthesis around your comparison operation, it's actually negating the entire comparison process, therefore returning the value you're after.
