Is there a built-in function in PHP that can be used to change the data type of a variable?

Yes, in PHP, you can use the settype() function to change the data type of a variable. This function allows you to explicitly set the type of a variable to a specified type, such as integer, string, float, etc. This can be useful when you need to ensure that a variable is of a certain type before performing operations on it. 

$variable = "123"; // variable is currently a string
settype($variable, "integer"); // change the data type of $variable to integer
echo $variable; // output: 123
