mt_getrandmax(): largest possible random value
Check the maximum mt_rand() value
mt_getrandmax() returns the largest value that mt_rand() can generate. It is mainly useful when working directly with the Mersenne Twister generator.
echo mt_getrandmax();
<?Php
echo mt_getrandmax(); // Maximum value available to mt_rand()
?>
int mt_getrandmax()
Returns the largest value that mt_rand() can return when no range is supplied.
For newly written code, PHP recommends the object-oriented Random\Randomizer API. Use random_int() when unpredictability is required.
