The str_shuffle Function

The str_shuffle function shuffles the characters in a string in random order. Works correctly only with Latin characters (single-byte characters).

Syntax

str_shuffle(string $string): string

Example

Let's shuffle the characters of a string in random order:

<?php
	echo str_shuffle('abcde');
?>

Example

Let's get a string of 3 digits so that the digits do not repeat:

<?php
	$digits = '0123456789';
	$shuffled = str_shuffle($digits);
	$res = substr($shuffled, 0, 3);
	
	echo $res;
?>
