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
