What are some best practices for handling data type conversions in PHP to avoid unexpected results?

When handling data type conversions in PHP, it is important to be aware of the potential for unexpected results due to PHP's loose typing system. To avoid issues, it is best practice to explicitly cast variables to the desired data type using functions like intval(), floatval(), strval(), or type casting. This ensures that the data is converted consistently and accurately.

// Example of handling data type conversions in PHP
$number = "10";
$convertedNumber = intval($number); // Explicitly cast $number to an integer

echo $convertedNumber; // Output: 10
