[SOLVED] Remove whitespace

[lococobra]

Okay... another regex problem...

 

Lets say I have the following:

<?php
$input ='foreach($some as $something) echo "ok";';
?>

 

I want to remove all whitespace from that string, but... I don't want to remove the whitespace around "as"

 

How would I get from that $input... using preg_replace... to the following output...

<?php
$output ='foreach($some as $something)echo"ok";';
?>

<pre>
<?php
echo $input ='foreach($some as $something) echo "ok";';
echo '<br>';
echo preg_replace('/(?<!as)\s+(?!as)/', '', $input);
?>
</pre>

You rule... how do you know so much about regex? If there's some online guide you learned from... point me in the direction please!
