How does PHP handle the transfer of data types from input fields in HTML forms?

When transferring data types from input fields in HTML forms to PHP, the data is typically received as strings. To handle different data types, we can use PHP functions like `intval()`, `floatval()`, or `boolval()` to convert the string input to the desired data type. 

// Example of handling different data types from input fields in HTML forms
$inputString = $_POST['input_field']; // Assuming the input field is named 'input_field'

// Convert string input to integer
$intValue = intval($inputString);

// Convert string input to float
$floatValue = floatval($inputString);

// Convert string input to boolean
$boolValue = boolval($inputString);
