What common mistake is highlighted in the PHP code snippet provided in the forum thread?

The common mistake highlighted in the PHP code snippet is the incorrect use of the `==` operator for comparison instead of the `===` operator. The `==` operator in PHP performs type juggling, which can lead to unexpected results. To ensure strict comparison without type coercion, the `===` operator should be used. 

// Incorrect comparison using ==
if ($var == 1) {
    echo "The variable is equal to 1";
}

// Correct comparison using ===
if ($var === 1) {
    echo "The variable is strictly equal to 1";
}
