Copy code The code is as follows:

function readable_random_string($length = 6){
$c
"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;
