What potential pitfalls should be considered when converting text data to integer data types in PHP?

When converting text data to integer data types in PHP, potential pitfalls to consider include ensuring that the text data is valid and can be safely converted to an integer without losing information or causing errors. It is important to handle exceptions or errors that may occur during the conversion process to prevent unexpected behavior in your application. 

// Example code snippet to safely convert text data to integer data types in PHP
$textData = "123";

// Check if the text data is a valid integer before conversion
if (ctype_digit($textData)) {
    $integerData = (int)$textData;
    echo $integerData;
} else {
    echo "Invalid text data, cannot convert to integer.";
}
