Question

How to get an array of all functions within a class in PHP?

Working in PHP 5.2.8.

Answer 1

You can do this using ReflectionClass

$class = new ReflectionClass('ClassName');
$methods = $class->getMethods();

$methods will return an array of ReflectionMethod objects, which you can then iterate through and get detailed information about each method:

foreach($methods as $method)
{
    // $method->getName()
    // $method->getParameters()
    // etc.
}
