Generate random numbers:
<?phpecho(mt_rand() . "<br>");echo(mt_rand() . "<br>");echo(mt_rand(10,100));?>The mt_rand() function uses the Mersenne Twister algorithm to generate random integers.
Tip: This function is a better choice for generating random values, returning results 4 times faster than the rand() function.
Tip: If you want a random integer between 10 and 100, inclusive, use mt_rand (10,100).
mt_rand();ormt_rand( min,max );
