PHP arraym map and method of item class

Question

I have array:

array(
  0 => new SomeClass(1),
  1 => new SomeClass(2),
  2 => new SomeClass(3),
)

How can I use array map to call method (non-static) of SomeClass class for each item in my array?

Do you need to use array_map specifically? or would a foreach not do? — gunnx

Why are you using array_map() instead of a foreach block? — Dan Blows

There's a more readable way than array_map or array_walk:

$instances = array(
  0 => new SomeClass(1),
  1 => new SomeClass(2),
  2 => new SomeClass(3),
)

foreach($instances as $instance)
{
    $instance->foo();
}

but if you really want array_map:

array_map(function($instance) {
    $instance->foo();
}, $instances);
