ID: 42789 Updated by: tony2001@php.net Reported By: kraghuba at in dot ibm dot com Status: Open Bug Type: Strings related Operating System: windows/linux PHP Version: 5CVS-2007-09-28 (snap) New Comment: join() is an alias of implode(), so the error messages is correct. Previous Comments: ------------------------------------------------------------------------ [2007-09-28 16:25:49] kraghuba at in dot ibm dot com Description: ------------ join() function doesn't generate proper warning messages when following conditions occur: 1) when join() is called with less than expected no. of argument, the warning message generated refers to implode function. Here is the actual output that is generated(in other warning it doesn't refer to implode function): Warning: join(): Argument to implode must be an array. in %s on line %d NULL 2) When the value of pieces argument is given other than an array, warning message generated is not giving enough info. It should be changed to indicate right required input type. Currently error message that get generated is as follows: Warning: join(): Bad arguments in C:\workdir\ibm\php6\ext\standard\tests\strings\join_variation2.php on line 89 bool(false) 3) the return value of this function differ on php5 and php6 when it generates an warning message: on php5, the return value is NULL on php6, the reutrn value is bool(false) I think, it should be consistent. Reproduce code: --------------- <?php $glue = ", "; var_dump( join($glue) ); // less than expected no. of args $pieces = 10; // not an array var_dump( join($glue, $pieces) ); ?> Actual result: -------------- on php6: --------- Warning: join(): Argument to implode must be an array in %s on line %d bool(false) Warning: join(): Bad arguments in %s on line %d bool(false) on php5: -------- Warning: join(): Argument to implode must be an array. in %s on line %d NULL Warning: join(): Bad arguments. in %s on line %d NULL ------------------------------------------------------------------------ -- Edit this bug report at http://bugs.php.net/?id=42789&edit=1
