How can debugging techniques be applied to identify why the user level is not incrementing from 0 to 1 in the PHP code?

The user level may not be incrementing from 0 to 1 in the PHP code due to a logical error in the code. To identify the issue, you can use debugging techniques like printing out the current value of the user level variable at different points in the code to see where it is getting stuck. Once you identify the issue, you can make the necessary adjustments to ensure the user level increments correctly. 

$userLevel = 0;

// Debugging point 1
echo "User level before increment: " . $userLevel . "<br>";

$userLevel++;

// Debugging point 2
echo "User level after increment: " . $userLevel . "<br>";
