#28305 [Opn->Bgs]: range problem

ID: 28305 Updated by: pollita@php.net Reported By: anakin at php dot pl -Status: Open +Status: Bogus Bug Type: Math related Operating System: Windows XP PHP Version: 4.3.4 New Comment: Thank you for taking the time to write to us, but this is not a bug. 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 From the manual: If you are picking only one entry, array_rand() returns the key for a random entry. Otherwise, it returns an array of keys for the random entries. This is done so that you can pick random keys as well as values out of the array. Your "actual results" are what you should expect, arrray KEYS 0 through 5.
