Test script: --------------- $returnValue = trim('someurl.net', '\\t'); $returnValue = "someurl.ne" or $returnValue = trim('someurl.net', ' \t\n\r\0\x0B/'); $returnValue = "someurl.ne" however this is fine ... $returnValue = trim('someurl.netx', '\t'); $returnValue = "someurl.netx" Expected result: ---------------- I did not expect that my url's .net domain would "lose" its ending "t" char as a result of performing a trim that included the tab "\t" entry within its char list. ------------------------------------------------------------------------ -- Edit this bug report at https://bugs.php.net/bug.php?id=70705&edit=1
