Are there any common pitfalls to avoid when converting a string to an integer in PHP?

One common pitfall to avoid when converting a string to an integer in PHP is not handling cases where the string cannot be converted to an integer, such as when the string contains non-numeric characters. To avoid this issue, you can use the `intval()` function in PHP, which will safely convert a string to an integer and handle cases where the string is not a valid integer.

$string = "123abc";
$integer = intval($string);
echo $integer;
