What are the potential pitfalls of comparing a string to an integer in PHP, as demonstrated in the provided code snippet?

Comparing a string to an integer in PHP can lead to unexpected results because PHP may attempt to automatically convert the types for comparison. This can result in non-intuitive behavior and potentially incorrect comparisons. To avoid this issue, it's best to explicitly convert the string to an integer before comparing. 

// Code snippet with fixed comparison
$string = "10";
$integer = 10;

if ((int)$string === $integer) {
    echo "The string and integer are equal.";
} else {
    echo "The string and integer are not equal.";
}
