How does PHP handle automatic type conversion and when should it be relied upon?

PHP handles automatic type conversion by converting variables from one data type to another when necessary. This can be convenient in some cases, but it can also lead to unexpected behavior if not used carefully. It is important to be aware of how PHP handles type conversion and to explicitly cast variables when needed to ensure the correct data type is being used. 

// Example of explicit type conversion
$number = "10";
$convertedNumber = (int) $number; // Explicitly convert the string "10" to an integer

echo $convertedNumber; // Output: 10
