Previous Comments: ------------------------------------------------------------------------ [2007-02-26 18:07:25] mfburdett at gmail dot com Same issue running the script via PHP commandline. Am installing snapshot in home directory now. ------------------------------------------------------------------------ [2007-02-26 16:46:19] tony2001@php.net Does PHP CLI work for you? What kind of Apache are you using? Version? MPM? Can you provide a GDB backtrace? Can you try building the snapshot (doesn't matter where, you don't have to install it, just build it and run the script using sapi/cli/php). ------------------------------------------------------------------------ [2007-02-26 16:36:22] mfburdett at gmail dot com <?php $regexp = '%(?:^|,\ *)("(?>[^"]*)(?>""[^"]* )*"|(?: [^",]*))%x'; $string = ''; preg_match_all($regexp, $string, $matches); ?> ------------------------------------------------------------------------ [2007-02-26 16:35:11] tony2001@php.net Notice: Undefined variable: string ------------------------------------------------------------------------ [2007-02-26 16:32:14] mfburdett at gmail dot com <?php $regexp = '%(?:^|,\ *)("(?>[^"]*)(?>""[^"]* )*"|(?: [^",]*))%x'; preg_match_all($regexp, $string, $matches); ?> ------------------------------------------------------------------------ The remainder of the comments for this report are too long.
