ReflectionParameter::hasType — Checks if parameter has a type
Checks if the parameter has a type associated with it.
此函数没有参数。
TRUE
if a type is specified, FALSE
otherwise.
Example #1 ReflectionParameter::hasType() example
<?php
function someFunction ( string $param , $param2 = null ) {}
$reflectionFunc = new ReflectionFunction ( 'someFunction' );
$reflectionParams = $reflectionFunc -> getParameters ();
var_dump ( $reflectionParams [ 0 ]-> hasType ());
var_dump ( $reflectionParams [ 1 ]-> hasType ());
以上例程的输出类似于:
bool(true) bool(false)
