Please double-check the documentation available at http://www.php.net/manual/ and the instructions on how to report a bug at http://bugs.php.net/how-to-report.php That's right. http://php.net/manual/en/function.strtr.php >If from and to have different lengths, the extra characters in the longer of the >two are ignored. The length of str will be the same as the return value's. Previous Comments: ------------------------------------------------------------------------ [2015-02-10 03:57:21] slevy1 at pipeline dot com 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 this bug report at https://bugs.php.net/bug.php?id=69022&edit=1
