Doc #63787 [NEW]: Array_unique notice (array to string conversion)

From: enumag at gmail dot com Operating system: any PHP version: 5.4.9 Package: Arrays related Bug Type: Documentation Problem Bug description:Array_unique notice (array to string conversion) Description: ------------ If array_unique gets an array of arrays as it's parameter and a custom $sort_flag is not provided, it throws this error (array to string conversion). The reason is obvious, any value is changed to a string and then compared. The problem is that it took me quite some time to figure it out and a less experienced programmer is totally clueless. Not sure if this can be fixed in PHP without BC break but at the very least it could be mentioned in documentation of array_unique function. -- Edit bug report at https://bugs.php.net/bug.php?id=63787&edit=1 -- Try a snapshot (PHP 5.4): https://bugs.php.net/fix.php?id=63787&r=trysnapshot54 Try a snapshot (PHP 5.3): https://bugs.php.net/fix.php?id=63787&r=trysnapshot53 Try a snapshot (trunk): https://bugs.php.net/fix.php?id=63787&r=trysnapshottrunk Fixed in SVN: https://bugs.php.net/fix.php?id=63787&r=fixed Fixed in release: https://bugs.php.net/fix.php?id=63787&r=alreadyfixed Need backtrace: https://bugs.php.net/fix.php?id=63787&r=needtrace Need Reproduce Script: https://bugs.php.net/fix.php?id=63787&r=needscript Try newer version: https://bugs.php.net/fix.php?id=63787&r=oldversion Not developer issue: https://bugs.php.net/fix.php?id=63787&r=support Expected behavior: https://bugs.php.net/fix.php?id=63787&r=notwrong Not enough info: https://bugs.php.net/fix.php?id=63787&r=notenoughinfo Submitted twice: https://bugs.php.net/fix.php?id=63787&r=submittedtwice register_globals: https://bugs.php.net/fix.php?id=63787&r=globals PHP 4 support discontinued: https://bugs.php.net/fix.php?id=63787&r=php4 Daylight Savings: https://bugs.php.net/fix.php?id=63787&r=dst IIS Stability: https://bugs.php.net/fix.php?id=63787&r=isapi Install GNU Sed: https://bugs.php.net/fix.php?id=63787&r=gnused Floating point limitations: https://bugs.php.net/fix.php?id=63787&r=float No Zend Extensions: https://bugs.php.net/fix.php?id=63787&r=nozend MySQL Configuration Error: https://bugs.php.net/fix.php?id=63787&r=mysqlcfg
