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 = 'helloworld'; and would like to randomly select a character from $string and echo the character and its position.

Answer 1

$str = 'helloworld';

$randomChar = $str[rand(0, strlen($str)-1)];

CodePad.

Answer 2

$string = 'helloworld'; 
$pos = rand(0,(strlen($string)-1));
echo $pos."th char is: ". $string[$pos];
