From: tokie at hanmail dot net Operating system: Linux 2.4.x (Fedora core 1) PHP version: 5.0.0b4 (beta4) PHP Bug Type: POSIX related Bug description: ereg_replace working weird with hexadeciaml escape code
Description: ------------ I was handling some broken text file. And I managed to fix it by replacing the ascii-control characters (0x00 to 0x1F) to avoid crash when INSERT the text into a db-table. But the ereg_replace replaces other critical characters such as 0-9 : < = > ... (seems to be 0x30 to 0x3F), too. Reproduce code: --------------- $str = "<a href='http://www.php.net/'>PHP.net</a>"; $result = ereg_replace("[\\x00-\\x1F]", "*", $str); // the result was: // *a href*'http*//www.php.net/'*PHP.net*/a* // not, // <a href='http://www.php.net/'>PHP.net</a> Expected result: ---------------- the function should replace only the characters ranging 0x00 ~ 0x1F only. Actual result: -------------- it replaced not only 0x00 - 0x1F but also 0x30 ~ 0x3F (I guess, and 0x20 ~ 0x2F seems to be safe) -- Edit bug report at http://bugs.php.net/?id=27257&edit=1 -- Try a CVS snapshot (php4): http://bugs.php.net/fix.php?id=27257&r=trysnapshot4 Try a CVS snapshot (php5): http://bugs.php.net/fix.php?id=27257&r=trysnapshot5 Fixed in CVS: http://bugs.php.net/fix.php?id=27257&r=fixedcvs Fixed in release: http://bugs.php.net/fix.php?id=27257&r=alreadyfixed Need backtrace: http://bugs.php.net/fix.php?id=27257&r=needtrace Need Reproduce Script: http://bugs.php.net/fix.php?id=27257&r=needscript Try newer version: http://bugs.php.net/fix.php?id=27257&r=oldversion Not developer issue: http://bugs.php.net/fix.php?id=27257&r=support Expected behavior: http://bugs.php.net/fix.php?id=27257&r=notwrong Not enough info: http://bugs.php.net/fix.php?id=27257&r=notenoughinfo Submitted twice: http://bugs.php.net/fix.php?id=27257&r=submittedtwice register_globals: http://bugs.php.net/fix.php?id=27257&r=globals PHP 3 support discontinued: http://bugs.php.net/fix.php?id=27257&r=php3 Daylight Savings: http://bugs.php.net/fix.php?id=27257&r=dst IIS Stability: http://bugs.php.net/fix.php?id=27257&r=isapi Install GNU Sed: http://bugs.php.net/fix.php?id=27257&r=gnused Floating point limitations: http://bugs.php.net/fix.php?id=27257&r=float
