ereg_replace the $a, $b characters

[Anon]

i have a problem with my regular expression script. I want to replace $a,$b with space, here is the

$string ="$apolerio$bBabao";
$string = ereg_replace("$a","",$string);

the problem is, it didn;t work, it outputs nothing, perhaps the problem is it islooking for the value of $a, and not the $a itself, how can i make my code treat the $a as characters and not as a $a with some value.

thanks

Try using ' around your variables instead of ". I haven't tested it but it seems like it might work..
