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'
    
);
}
?>

The above example will output something similar to:

 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 }
