What potential issue arises when using multiple random operations in PHP code?

When using multiple random operations in PHP code, there is a potential issue of generating the same random number if the operations are called in quick succession. To solve this issue, you can use the `mt_rand()` function instead of `rand()` as it provides better random number generation.

// Using mt_rand() for better random number generation
$randomNumber1 = mt_rand(1, 100);
$randomNumber2 = mt_rand(1, 100);
