Php Randomize Array (Shuffle)
- 2 Comment
If you want to randomize a php array , you can use shuffle function.
But we can’t randomize the whole array with its value, it might be integer, string or collection of objects etc. So we randomize or shuffle the keys of the array.
Eg:
$Keys = array_keys($MyArray);
shuffle($Keys);
$NewArray = array(); //declare a new array
foreach( $Keys as $key)
{
$NewArray[] = $MyArray[$key];
}
Here the NewArray will be the shuffle of MyArray
Thanks

It doesn’t work. It shuffles the keys, but some keys have been lost after shuffling. Bad tip…
