Course Introduction:Customizing function parameter type validation in PHP can enforce parameter types to ensure they are as expected, thereby improving code robustness. This can be achieved by: Type hints: Declare the expected types of function parameters, mismatching types will throw an exception. Type conversion: Use the settype function or operator to convert a variable to a specified type. Type inference: PHP automatically infers variable types, such as when assigning values. Custom validation: Create a custom validation function to validate specific types (such as dates). Practical case: Demonstrate the usage of custom verification through the name verification function to ensure that the name length and format meet the requirements.
