Previous Comments: ------------------------------------------------------------------------ [2005-05-31 14:13:57] sniper@php.net I stand corrected, fix coming up.. ------------------------------------------------------------------------ [2005-05-31 12:53:41] astax_t at gorodok dot net And additionally, it makes impossible to use preg_replace with /e modifier in certain situations. When subject string comes from external source and so can contain some variables, like in my example. I still insist that it's a bug. Thank you. ------------------------------------------------------------------------ [2005-05-31 12:49:18] astax_t at gorodok dot net I know how magic_quotes_sybase works, but I state that it should NOT affect /e modifier in regular expressions. The same as magic_quotes_gpc and magic_quotes_runtime doesn't affect this. ------------------------------------------------------------------------ [2005-05-31 12:43:22] sniper@php.net RTFM: "If magic_quotes_sybase is also on, a single-quote is escaped with a single-quote instead of a backslash." ------------------------------------------------------------------------ [2005-05-31 12:36:09] astax_t at gorodok dot net Description: ------------ When magic_quotes_sybase is On, this also affects how apostrophes are escaped in preg_replace with /e modifier. See example. In example code I specifically included a string with $ inside to point why it's impossible to use double quotes around \\1 in second parameter. Reproduce code: --------------- $str = 'some \'$sample\' text'; $str = preg_replace("/(some.*text)/e", "strtoupper('\\1')", $str); echo $str; Expected result: ---------------- SOME '$SAMPLE' TEXT Actual result: -------------- Parse error: parse error in E:\test\web\a.php(4) : regexp code on line 1 Fatal error: preg_replace(): Failed evaluating code: strtoupper('some ''$sample'' text') in E:\test\web\a.php on line 4 ------------------------------------------------------------------------ -- Edit this bug report at http://bugs.php.net/?id=33200&edit=1
