a method of selecting random characters from given string

Question

Can anyone help me with a solution that pulls the position and value of a random character from a given string using PHP. For example I have a a string variable $string = \

Answer 1

You can use the rand($x,$y) function which returns a random number between $x and $y inclusive:

$str = 'helloworld';

// get a random index between 0 and the last valid index
$rand_pos = rand(0,strlen($str)-1);

// access the char at the random index.
$rand_chr = $str[$rand_pos];
