I need some php help.

I need to replace &acirc; followed by two unknown characters with an
empty string.

I tried this, but it's not quite right:


$newstring=preg_replace ("/&acirc;??/i", "",$newstring);

Any ideas?

You didn't specify what these unknown characters should be.
I am guessing non-whitespace. In that case this would be appropriate:

$newstring=preg_replace ('/&acirc;\S\S/i', '',$newstring);

So that would match:
&acirc;abcer

But wouldn't match:
&acirc; asdasd

or...
&acirc;a sdasd

Note the "single" quotes (apostrophe) instead of your double quotes (that 
don't need to escape backslash).

If you want to match anything then use:
$newstring=preg_replace ('/&acirc;../i', '',$newstring);

That would match any case of the above.

"Not quite right". Nice description. As useful as "Does not work" :)

The "?" symbol means "any character" in Windows wildcards but not in 
regular expressions. You want "." instead:

<?php
var_dump( preg_replace ('/&acirc;../i', '', '&acirc;abKeep Me!') );
