I have a simple code: mt_rand(1,25);
it is generating the same number over and over. MANY times before it will finally generate a new number.
6 months ago, it worked beautifully.
$X = mt_rand(1,25) ;
$AR=array(14, 126, 28, .......);
$F = $AR[$X];
Then the $F is used in a math calculation...
The $X value is the one remaining the same on every page refresh or revisit.

Select "Numbers Plus 9" on second row of buttons. Input a name and then the code should be generating different flashcards each time.
Your code is only calling mt_rand() a single time. If you are using this in a loop, please include the other statements in the loop.
Possible pitfalls:
You are calling mt_srand() elsewhere in the loop, which is resetting the random state for each time through the loop.
You are comparing successive executions of the script itself, and you have a PHP version that is out of date (all still-supported PHP versions initially seel the random state with a random value upon script execution).
