Re: Determining an external function/method's argument/parameter listing..?

Ok, thanks for that referral.

The following code shows a bit of a simple usage of the reflectionMethod 
class, on a quickly generated test class and one of it's methods:

<?php
class myClass
{
public function __init() {

}//end of __init

public function anything($sVar1 = "5") {

}//end of anything function
}//end of myClass

$className = "myClass";
$methodName = "anything";
$r = new ReflectionMethod($className, $methodName);
$params = $r->getParameters();
echo "<ul>\n";
foreach ($params as $param)
{
echo "<li><ul>\n";
echo "<li>parameter: " . $param->getName() . "</li>\n";
echo "<li>allowsNull: " . strval($param->allowsNull()) . "</li>\n";
echo "<li>optional: " . strval($param->isOptional()) . "</li>\n";
if ($param->isOptional()) { echo "<li>defaultValue: " . 
$param->getDefaultValue() . "</li>\n"; }
echo "</ul></li>";
}
echo "</ul>\n";

?>


Stay well
