Guys I just came across the __call() PHP function. I tried to understand what this is used through the manual here http://php.net/manual/en/language.oop5.overloading.php#object.call But all that is mentioned here is that
__call() is triggered when invoking inaccessible methods in an object context.
which is not really clear honestly. I tried looking for other examples online, but they all seem complicated. Can anyone explain using a simple example what is __call() and what is it good for?
Consider this:
class Foo
{
public function __call($name, $args)
{
echo "you tried to call method $name with these args:";
print_r($args);
}
}
$foo = new Foo();
$foo->bar($args);
Note there is no method named bar. Normally, calling it will produce an error. However, in this case, you've defined a __call() method. So, instead of generating an error, PHP will invoke this method, passing it the name of the method you tried to call, and the arguments you tried to call it with.
__callis executed when you try to invoke non-existent method in class. PHP page you provided has an example.
