What is the potential issue with the PHP code provided in the forum thread regarding the variable increment?

The potential issue with the PHP code provided in the forum thread is that the variable increment is not being done correctly. The code is using the post-increment operator ($i++) instead of the pre-increment operator (++$i), which means that the current value of $i is being used in the loop before it is incremented. To solve this issue, we need to use the pre-increment operator (++$i) so that $i is incremented before its value is used in the loop. 

$i = 0;
while ($i < 10) {
    echo $i . "<br>";
    ++$i;
}
