Get PHP class property by string

How do I get a property in a PHP based on a string? I'll call it magic. So what is magic?

$obj->Name = 'something';
$get = $obj->Name;

would be like...

magic($obj, 'Name', 'something');
$get = magic($obj, 'Name');

Solution 1:

Like this

<?php

$prop = 'Name';

echo $obj->$prop;

Or, if you have control over the class, implement the ArrayAccess interface and just do this

echo $obj['Name'];

If you want to access the property without creating an intermediate variable, use the {} notation:

$something = $object->{'something'};

That also allows you to build the property name in a loop for example:

for ($i = 0; $i < 5; $i++) {
    $something = $object->{'something' . $i};
    // ...
}
