preg_replace is a bit overkill

$string = ',,ABCD,EFG,,,,';
$newString trim($string,',');

Do you mean

preg_replace('/^,|,$/', '', ',test,hi,');

? Inside a character class […], a leading ^ means negation, and $ doesn't have any special meanings.

You could use the trim function instead.

trim(',test,hi,', ',');
