What potential problem can arise when using count() function in the for loop to iterate through the UID values in PHP?

Using the count() function in the for loop to iterate through UID values in PHP can lead to performance issues as the count() function is called in every iteration, resulting in unnecessary overhead. To solve this problem, you can store the count value in a variable before the loop and then use that variable in the loop condition. 

$uids = [1, 2, 3, 4, 5];
$uidCount = count($uids);

for ($i = 0; $i < $uidCount; $i++) {
    $uid = $uids[$i];
    // Perform operations with $uid
}
