LEARN ABOUT PHP
array_rand
ARRAY_RAND(3) 1 ARRAY_RAND(3)
array_rand - Pick one or more random entries out of an array
SYNOPSIS
mixed array_rand (array $array, [int $num = 1])
DESCRIPTION
Picks one or more random entries out of an array, and returns the key (or keys) of the random entries.
PARAMETERS
o $array
- The input array.
o $num
- Specifies how many entries should be picked.
RETURN VALUES
When picking only one entry, array_rand(3) returns the key for a random entry. Otherwise, an array of keys for the random entries is
returned. This is done so that random keys can be picked from the array as well as random values. Trying to pick more elements than there
are in the array will result in an E_WARNING level error, and NULL will be returned.
