PHP generates readable random string

How does PHP generate a readable random string? This article will share a piece of code that randomly generates readable strings. I hope it will be helpful to everyone.

This code will create a readable string that is closer to the word in the dictionary, practical and has password verification capabilities.

/************** 
*@length - length of random string (must be a multiple of 2) 
**************/ 
function readable_random_string($length = 6){ 
    $conso=array("b","c","d","f","g","h","j","k","l", 
    "m","n","p","r","s","t","v","w","x","y","z"); 
    $vocal=array("a","e","i","o","u"); 
    $password=""; 
    srand ((double)microtime()*1000000); 
    $max = $length/2; 
    for($i=1; $i<=$max; $i++) 
    { 
        $password.=$conso[rand(0,19)]; 
        $password.=$vocal[rand(0,4)]; 
    } 
    return $password; 
}
