Bug #52923 [NEW]: parse_url corrupts some UTF-8 strings

From: Operating system: MS Windows XP PHP version: 5.3.3 Package: *URL Functions Bug Type: Bug Bug description:parse_url corrupts some UTF-8 strings Description: ------------ I have tested this with PHP 5.2.9 and 5.3.3. Some UTF-8 strings are not being processed correctly by parse_url. In the given example, the result of the evaluation of strings which contains the chars 'ם' or 'א' is corrupt, whereas the string 'מישהו'(which does not contain the above chars) is being processed correctly. The affected characters (in UTF-8) are comprised of the following bytes: ם - d7|9d א - d7|90 Those are converted to a char which contains the following bytes: d7|5f. In addition to ruining the url, this char is not safe with preg_replace. Therefore, if we merge the result of parse_url back into a string, and then attempting to replace, say, spaces with underscores using preg_replace, we will get an empty string. I believe that this is similar to bug #26391. Test script: --------------- $url = 'http://www.mysite.org/he/פרויקטים/ByYear.html'; $url = parse_url($url); //$url['path'] is now corrupt $url = preg_replace('/\s+/u','_',$url['path']); //$url is now undefined Expected result: ---------------- The correct portion of the url. Actual result: -------------- Corrupt string (or blank after using preg_replace). -- Edit bug report at http://bugs.php.net/bug.php?id=52923&edit=1 -- Try a snapshot (PHP 5.2): http://bugs.php.net/fix.php?id=52923&r=trysnapshot52 Try a snapshot (PHP 5.3): http://bugs.php.net/fix.php?id=52923&r=trysnapshot53 Try a snapshot (trunk): http://bugs.php.net/fix.php?id=52923&r=trysnapshottrunk Fixed in SVN: http://bugs.php.net/fix.php?id=52923&r=fixed Fixed in SVN and need be documented: http://bugs.php.net/fix.php?id=52923&r=needdocs Fixed in release: http://bugs.php.net/fix.php?id=52923&r=alreadyfixed Need backtrace: http://bugs.php.net/fix.php?id=52923&r=needtrace Need Reproduce Script: http://bugs.php.net/fix.php?id=52923&r=needscript Try newer version: http://bugs.php.net/fix.php?id=52923&r=oldversion Not developer issue: http://bugs.php.net/fix.php?id=52923&r=support Expected behavior: http://bugs.php.net/fix.php?id=52923&r=notwrong Not enough info: http://bugs.php.net/fix.php?id=52923&r=notenoughinfo Submitted twice: http://bugs.php.net/fix.php?id=52923&r=submittedtwice register_globals: http://bugs.php.net/fix.php?id=52923&r=globals PHP 4 support discontinued: http://bugs.php.net/fix.php?id=52923&r=php4 Daylight Savings: http://bugs.php.net/fix.php?id=52923&r=dst IIS Stability: http://bugs.php.net/fix.php?id=52923&r=isapi Install GNU Sed: http://bugs.php.net/fix.php?id=52923&r=gnused Floating point limitations: http://bugs.php.net/fix.php?id=52923&r=float No Zend Extensions: http://bugs.php.net/fix.php?id=52923&r=nozend MySQL Configuration Error: http://bugs.php.net/fix.php?id=52923&r=mysqlcfg
