ReflectionParameter::__construct — Construct
$function
, string $parameter
)Constructs a ReflectionParameter class.
本函数还未编写文档,仅有参数列表。
function
The function to reflect parameters from.
parameter
The parameter.
没有返回值。
Example #1 Using the ReflectionParameter class
<?php
function foo ( $a , $b , $c ) { }
function bar ( Exception $a , & $b , $c ) { }
function baz ( ReflectionFunction $a , $b = 1 , $c = null ) { }
function abc () { }
$reflect = new ReflectionFunction ( 'foo' );
echo $reflect ;
foreach ( $reflect -> getParameters () as $i => $param ) {
printf (
"-- Parameter #%d: %s {\n" .
" Class: %s\n" .
" Allows NULL: %s\n" .
" Passed to by reference: %s\n" .
" Is optional?: %s\n" .
"}\n" ,
$i , // $param->getPosition() can be used from PHP 5.2.3
$param -> getName (),
var_export ( $param -> getClass (), 1 ),
var_export ( $param -> allowsNull (), 1 ),
var_export ( $param -> isPassedByReference (), 1 ),
$param -> isOptional () ? 'yes' : 'no'
);
}
?>
以上例程的输出类似于:
Function [ <user> function foo ] { @@ /Users/philip/cvs/phpdoc/a 2 - 2 - Parameters [3] { Parameter #0 [ <required> $a ] Parameter #1 [ <required> $b ] Parameter #2 [ <required> $c ] } } -- Parameter #0: a { Class: NULL Allows NULL: true Passed to by reference: false Is optional?: no } -- Parameter #1: b { Class: NULL Allows NULL: true Passed to by reference: false Is optional?: no } -- Parameter #2: c { Class: NULL Allows NULL: true Passed to by reference: false Is optional?: no }

You also can use a class instead of a function name. Just use an array like that
<?php
$reflect = new ReflectionParameter(array('className', 'methodName'), 'property');
?>
