How can using multiple random operations in PHP code lead to unexpected results?

Using multiple random operations in PHP code can lead to unexpected results because each call to a random function generates a new random value. This means that if multiple random functions are called in close succession, they may produce the same random value, leading to non-random behavior. To solve this issue, you can seed the random number generator with a specific value using srand() before making any random function calls.

// Seed the random number generator
srand(1234);

// Generate random numbers
$randomNumber1 = rand();
$randomNumber2 = rand();

echo $randomNumber1 . "\n";
echo $randomNumber2 . "\n";
