mt_rand() and mt_srand()
mt_rand()
This function is used to generate the rendom value.
And also we can pass the optional arguments minimum and maximum
for example
if we use mt_rand like mt_rand(5,10), it will generate the random value between 5 and 10.
mt_srand()
If we include mt_srand() function before we use mt_rand(), those we can get the better random values.
Example:
mt_srand(time());
echo $randval = mt_rand();
