A method of random exchange of elements in an array of PHP

In this paper, we describe the method of random exchange of elements in the log group of PHP. Share to everyone for your reference. The specific analysis is as follows:

This is a custom PHP array element random swap function, PHP already has a built-in function of the same function shuffle ($Array), this code right when referenced

?

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24-25

I noticed that there are already a built-in function that//Does the same-so don ' t use mine;--////--> Shuffle ( $Array); http://de2.php.net/manual/de/function.shuffle.php//function Randomizearray ($array) {//error check: $array = (!is _array ($array))? Array ($array): $array; $a = array (); $max = count ($array) + 10; while (count ($array) > 0) {$e = Array_shift ($array); $r = rand (0, $max);//Find a empty key:while (Isset ($a [$r])) {$r = rand (0, $max); } $a [$r] = $e; } ksort ($a); $a = array_values ($a); return $a; }

Use Example:

1 2 3 4 5 6 7 8 9 10 11-12

* * * * * Example: * * $test _array = Array (' Why ', ' dont ', ' visit ', ' www ', ' Jonas ', ' John ', ' de ', ':-) '); Print implode (",", $test _array); Print "n"; Print implode (",", Randomizearray ($test _array)); * Example output:why, dont, visit, www, Jonas, John, DE,:-) www, DE, Jonas, John, visit, why,:-), dont * *
