Using $this when not in object context - php

Question

maybe it is to early in the morning or I'm totally blind, but why to I get a 'Fatal error: Using $this when not in object context' in the following code. There is nothing static in there.
The class:
<?php
class Property
{
/**
* #var string[]
*/
private $values;
public function __contruct($file)
{
$this->values = parse_ini_file($file, false);
}
/**
* #return string
*/
public function get($key, $default = null)
{
if (key_exists($key, $this->values)) { //<-- error
return $this->values[$key];
}
return $default;
}
}
The test:
<?php
class PropertyTest extends Test
{
public function testGet()
{
$prop = new Property($this->getResource('test.properties'));
$this->assertEquals('foo', $prop->get('test.entry', 'xyz'));
$this->assertEquals('bar', $prop->get('test.entry2', 'xyz'));
$this->assertEquals('xyz', $prop->get('test.entry3', 'xyz'));
$this->assertEquals(null, $prop->get('test.entry3'));
}
}
Edit
The error comments indicating the trace. The error occures while running the PropertyTest->testGet() on the the first $prop->get() caused by the first line of the Property->get() method.
Solution
Beside the typo xdazz found, and the deprecation Phil pointed at, user985935 was right. :)
To make it short, my class loader used the static get and the phpUnit error mislead my investigations and my information I offer you for finding my problem. Sorry.

Answer 1

There is a typo in your code.
public function __contruct($file)
which should be
public function __construct($file)

Answer 2

'Fatal error: Using $this when not in object context'
The $this keyword points to methods that are inside an object only you can't use $this outside an object I think this is what causing your problem
