How can I access an object property named as a variable in php?

Since the name of your property is the string '$t', you can access it like this:

echo $object->{'$t'};

Alternatively, you can put the name of the property in a variable and use it like this:

$property_name = '$t';
echo $object->$property_name;

You can see both of these in action on repl.it: https://repl.it/@jrunning/SpiritedTroubledWorkspace


Correct answer (also for PHP7) is:

$obj->{$field}

I'm using php7 and the following works fine for me:

class User {
    public $name = 'john';
}
$u = new User();

$attr = 'name';
print $u->$attr;

Have you tried:

$t = '$t'; // Single quotes are important.
$object->$t;
