TypeError

(PHP 7)

Introduction

There are three scenarios where a TypeError may be thrown. The first is where the argument type being passed to a function does not match its corresponding declared parameter type. The second is where a value being returned from a function does not match the declared function return type. The third is where an invalid number of arguments are passed to a built-in PHP function (strict mode only).
