I have the following preg_replace function
preg_replace('/[\$,Audio, CD, Audiobook, MP3 Audio, Unabridged]/','',$audibleinnertextpieces)
this is my regular expression to replace either the $ or the WHOLE string
Audio, CD, Audiobook, MP3 Audio, Unabridged
for some reason it is removing the U in all my strings, I just want to replace if the WHOLE string is found to match Audio, CD, Audiobook, MP3 Audio, Unabridged
You could just use str_replace
str_replace(array('$', 'Audio, CD, Audiobook, MP3 Audio, Unabridged'), '', $str);
Don't use regex for these kind of searches. Why not use plain str_replace?
$str = str_replace(array('$', 'Audio, CD, Audiobook, MP3 Audio, Unabridged'), '', $source_string);
Why not just use str_replace instead:
str_replace(array('$','Audio, CD, Audiobook, MP3 Audio, Unabridged'),'',$string);
If you know the EXACT string that you want replaced, a regular expression is overkill.
In regular expressions square brackets create a character class which will one single character from any character between the brackets. So [abc] would match either 'a', 'b', or 'c'.
If you want to match $ or Audio, CD, Audiobook, MP3 Audio, Unabridged then you want alternation, which is accomplished by separating the pieces with a |:
preg_replace('/\$|Audio, CD, Audiobook, MP3 Audio, Unabridged/','',$audibleinnertextpieces)
str_replace is preferable here, but I think the downvote is a bit much. This answer is correct and it is the only one that explains what was wrong with the OP's attempt.You can use the regex
$regex = "/\$|Audio, CD, Audiobook, MP3 Audio, Unabridged/"
which will search for either the $ symbol or the entire string. then just use
$result = preg_replace($regex, '' ,$audibleinnertextpieces)
Which will strip any of the search terms out
