I've been trying to wrap my head around solving this issue but I can't seem to find a simple solution to it.
I have a dynamic grid layout, articles are placed on the grid but have different width & height. This width & height of these different articles can change upon visiting the site but only when there is a new article added.
The issue is I have logic that uses mt_rand to generate random numbers within a range (to fit in the layout grid), is there a way I can pass in a seed (planning to use the newest article id) so that the random numbers are consistent until a new article is introduced? I wanted to use mt_srand but there doesn't seem to be an easy way to limit the random number within a range.
Thanks.

What is a Random Seed? A random seed is a starting point in generating random numbers. A random seed specifies the start point when a computer generates a random number sequence. This can be any number, but it usually comes from seconds on a computer system's clock (Henkemans & Lee, 2001).
Use a random. randrange() function to get a random integer number from the given exclusive range by specifying the increment. For example, random. randrange(0, 10, 2) will return any random number between 0 and 20 (like 0, 2, 4, 6, 8).
Not actually random, rather this is used to generate pseudo-random numbers. That implies that these randomly generated numbers can be determined. random() function generates numbers for some values. This value is also called seed value.
If you want to use RAND to generate a random number but don't want the numbers to change every time the cell is calculated, you can enter =RAND() in the formula bar, and then press F9 to change the formula to a random number. The formula will calculate and leave you with just a value.
mt_srand() is used to set your seed and mt_rand() takes in a min and max if you want to set the range. Basically something like:
mt_srand($seed);
mt_rand($min, $max);
Note: As of PHP 4.2.0, there is no need to seed the random number generator with srand() or mt_srand() as this is now done automatically.
