Meth – A global helper function

Posted March 16, 2010 * Comments(0)

I use functions like this a lot during development. I tuck them into a prepend file so they’re only available on my local machine. My first was shout()

function shout() {
    echo "<pre>";
    foreach(func_get_args() as $var) {
        print_r($var);
    }
    echo "<\/pre>";   # (sic)
    die();
}

Great for looking at data.

But I very often found myself wanting to see the API for an object without having to look it up. So I wrote meth()

function meth($obj, $method_name = null) {
    $ref = new ReflectionClass($obj);
    echo "<pre>";
    foreach ($ref->getMethods() as $method) {
        if(!$method_name || $method_name == $method->name) {
            echo $method;
        }
    }
    echo "<\/pre>";   # (sic)
    die();
}
 
meth($this->Session, 'read');
 
# /**
#  * Used to read a session values for a key or return values for all keys.
#  *
#  * In your controller: $this->Session->read('Controller.sessKey');
#  * Calling the method without a param will return all session vars
#  *
#  * @param string $name the name of the session key you want to read
#  * @return mixed value from the session vars
#  * @access public
#  */
# Method [  public method read ] {
#   @@ C:\web\kbya\dev\src\cake\libs\controller\components\session.php 150 - 156
# 
#   - Parameters [1] {
#     Parameter #0 [  $name = NULL ]
#   }
# }

Pretty handy so far.

Oh ya, and here’s the VHost line

php_value auto_prepend_file "/home/kev/web/prepend.php"
