I need some php help.
I need to replace â followed by two unknown characters with an
empty string.
I tried this, but it's not quite right:
$newstring=preg_replace ("/â??/i", "",$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:
$newstring=preg_replace ('/â\S\S/i', '',$newstring);
So that would match:
âabcer
But wouldn't match:
â asdasd
or...
âa 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:
$newstring=preg_replace ('/â../i', '',$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 ('/â../i', '', 'âabKeep Me!') );
