String Replace Problems

Hello, I'm new to PHP and to regular expressions. I'm trying to do a str_replace and it's driving me nuts. I've tried a dozen combinations and none of them work. I've read the str_replace and the ereg_replace stuff in the on-line manual and I'm still at a loss for the right formatting. Here's the string that needs replacing (it's so simple, it's embarrassing): "75%"></center> </td> </tr> I can replace the ["75%"</center>] part using $printing[1] = str_replace('"75%"></center>', '<table>'; $printing[1]; ... but when I switch the string to double quotes ("...") and then try to account for those literal quotes and the line endings I screw up. Help would be appreciated, I know I'm missing something easy. Cheers, Mark -- mark mark--allen@usa.net
