Those are HTML entities (or sometimes refered to as ASCII characters, though I was told that was not the correct name for them). Do you want to get rid of them altogether? If so, use
.

Have you read the manual page I refered you to? It gives examples. Try one. If it doesn't work, post back.

Code: Select all
$string = preg_replace('/&#\d+;/', '', $string);
Using str_replace() could be better though. Just str_replace all & to &

str_ functions are faster than preg_ functions. But if this is not a high volume app, or you need the flexibility of regular expression matching, use the preg_ functions.
