From: slevy1 at pipeline dot com Operating system: PHP version: 5.6.5 Package: Scripting Engine problem Bug Type: Bug Bug description:strtr fails to consistently translate to an empty string Description: ------------ If I provide strtr a from value like a comma, and a to value like an empty string, since the from value is longer than the to value, the translation fails to occur. However, if I provide the from and to values in an associative array, then the comma in the from value is replaced by an an empty string in the to value. Test script: --------------- <?php $nums = "1,2,3,\n,4,5,6,\n,7,8,9"; echo strtr($nums,array("," => "")); echo "\n\n"; echo strtr($nums,",",""); Expected result: ---------------- 123 456 789 123 456 789 Actual result: -------------- 123 456 789 1,2,3, ,4,5,6, ,7,8,9 -- Edit bug report at https://bugs.php.net/bug.php?id=69022&edit=1 -- Try a snapshot (PHP 5.4): https://bugs.php.net/fix.php?id=69022&r=trysnapshot54 Try a snapshot (PHP 5.5): https://bugs.php.net/fix.php?id=69022&r=trysnapshot55 Try a snapshot (trunk): https://bugs.php.net/fix.php?id=69022&r=trysnapshottrunk Fixed in SVN: https://bugs.php.net/fix.php?id=69022&r=fixed Fixed in release: https://bugs.php.net/fix.php?id=69022&r=alreadyfixed Need backtrace: https://bugs.php.net/fix.php?id=69022&r=needtrace Need Reproduce Script: https://bugs.php.net/fix.php?id=69022&r=needscript Try newer version: https://bugs.php.net/fix.php?id=69022&r=oldversion Not developer issue: https://bugs.php.net/fix.php?id=69022&r=support Expected behavior: https://bugs.php.net/fix.php?id=69022&r=notwrong Not enough info: https://bugs.php.net/fix.php?id=69022&r=notenoughinfo Submitted twice: https://bugs.php.net/fix.php?id=69022&r=submittedtwice register_globals: https://bugs.php.net/fix.php?id=69022&r=globals PHP 4 support discontinued: https://bugs.php.net/fix.php?id=69022&r=php4 Daylight Savings: https://bugs.php.net/fix.php?id=69022&r=dst IIS Stability: https://bugs.php.net/fix.php?id=69022&r=isapi Install GNU Sed: https://bugs.php.net/fix.php?id=69022&r=gnused Floating point limitations: https://bugs.php.net/fix.php?id=69022&r=float No Zend Extensions: https://bugs.php.net/fix.php?id=69022&r=nozend MySQL Configuration Error: https://bugs.php.net/fix.php?id=69022&r=mysqlcfg
