strange double quotes

when i do an insert on a mysql db,the damn thing refuses to take a double quote.it will take everthing b4 the quote but not the quote itself or anything after it. i use addslashes.is mysql a bit tempremental about double quotes or what? an ereg_replace don't seem to be working either.e.g $pat = '"'; $rep = '"'; $content = ereg_replace($pat,$rep,$content); this whole thing seems strange to me as addslashes has worked b4.
