From: info at maduranma dot com Operating system: Windows PHP version: 7.0.9 Package: Arrays related Bug Type: Bug Bug description:Bug in str_replace with arrays if the second one starts with a space Description: ------------ In the code below, if you change the first "' '" of the second array in the str_replace function with some kind of value it doesn't happen, but if you do not, it takes it to the last value of the array, that's "'0'" and you can change it to "'ssdsad'" (for example) and you'll see that it takes the last value. Test script: --------------- $msg = 'AABB'; $msg = str_replace(array('A', 'B', 'C', 'D', 'E', 'F', 'G', 'H', 'I', 'J', 'K', 'L', 'M', 'N', 'Ñ', 'O', 'P', 'Q', 'R', 'S', 'T', 'U', 'V', 'W', 'X', 'Y', 'Z', '1', '2', '3', '4', '5', '6', '7', '8', '9', '0', ' '), array(' ', 'A', 'B', 'C', 'D', 'E', 'F', 'G', 'H', 'I', 'J', 'K', 'L', 'M', 'N', 'Ñ', 'O', 'P', 'Q', 'R', 'S', 'T', 'U', 'V', 'W', 'X', 'Y', 'Z', '1', '2', '3', '4', '5', '6', '7', '8', '9', '0'), $msg); // N-1 echo $msg; Expected result: ---------------- AA Actual result: -------------- 00AA -- Edit bug report at https://bugs.php.net/bug.php?id=72797&edit=1 -- Try a snapshot (PHP 5.4): https://bugs.php.net/fix.php?id=72797&r=trysnapshot54 Try a snapshot (PHP 5.5): https://bugs.php.net/fix.php?id=72797&r=trysnapshot55 Try a snapshot (trunk): https://bugs.php.net/fix.php?id=72797&r=trysnapshottrunk Fixed in SVN: https://bugs.php.net/fix.php?id=72797&r=fixed Fixed in release: https://bugs.php.net/fix.php?id=72797&r=alreadyfixed Need backtrace: https://bugs.php.net/fix.php?id=72797&r=needtrace Need Reproduce Script: https://bugs.php.net/fix.php?id=72797&r=needscript Try newer version: https://bugs.php.net/fix.php?id=72797&r=oldversion Not developer issue: https://bugs.php.net/fix.php?id=72797&r=support Expected behavior: https://bugs.php.net/fix.php?id=72797&r=notwrong Not enough info: https://bugs.php.net/fix.php?id=72797&r=notenoughinfo Submitted twice: https://bugs.php.net/fix.php?id=72797&r=submittedtwice register_globals: https://bugs.php.net/fix.php?id=72797&r=globals PHP 4 support discontinued: https://bugs.php.net/fix.php?id=72797&r=php4 Daylight Savings: https://bugs.php.net/fix.php?id=72797&r=dst IIS Stability: https://bugs.php.net/fix.php?id=72797&r=isapi Install GNU Sed: https://bugs.php.net/fix.php?id=72797&r=gnused Floating point limitations: https://bugs.php.net/fix.php?id=72797&r=float No Zend Extensions: https://bugs.php.net/fix.php?id=72797&r=nozend MySQL Configuration Error: https://bugs.php.net/fix.php?id=72797&r=mysqlcfg
