What potential pitfalls can arise when comparing integers with strings in PHP, as seen in the code provided?

When comparing integers with strings in PHP, potential pitfalls can arise due to PHP's loose data type comparison. PHP may attempt to convert the string to an integer for comparison, leading to unexpected results. To avoid this issue, it's important to explicitly convert the variables to the same data type before comparing them. 

<?php
$number = 10;
$stringNumber = "10";

// Explicitly convert the string to an integer before comparison
if ($number === (int)$stringNumber) {
    echo "The integers are equal.";
} else {
    echo "The integers are not equal.";
}
?>
