array_search() From Static Property

[livethedead]

Alright so, firstly this script serves no real purpose other than me practicing OOP. The problem is, I want to get the key of the value _input_word from Library::_translators. I can't seem to figure out why its not working I've been trying to debug it and figured out the problem is occurring at the array_search function. Theres no actual error though because it all executes but I am not getting a key. On a side note I'm sure I horridly used exceptions wrong so feel free to point out any suggestions there if you'd like. I realize I could of wrote this much much easier structurally but like I said, for practice.

 

Here's the problem section:

	private function makeTranslation() {
		$check = getCheck();
		if ($check = true) {
			$this->_key = array_search(getInput(), Library::$_translators);
			$this->_translation = Library::$_translations[$this->_key];
		}	else {
				try {
					throw new Exception("fuuu");
				}	catch(Exception $e) {
						echo $e->getMessage();
					}
			}
	}

 

 

Here's the whole code.

 

<?php

abstract class Library {
	static $_translators = array("what the fuck", "thank you",
	"see ya");

	static $_translations = array("wtf", "ty", "cya");	
}

class Input extends Library {
	private $_input_word;
	private $_check;

	function __construct($input) {
		if (in_array($input, Library::$_translators)) {
			$this->_input_word = $input;
			$this->_check = true;
		}	else {
				try {
					if (!$this->_check) {
						throw new Exception("Word not found in library.");
					}
				}		
					catch(Exception $e) {
					echo $e->getMessage();
					}


			}
	}

	protected function getInput() {
		return $this->_input_word;
	}

	protected function getCheck() {
		return $this->_check;
	}
}	



abstract class Translation extends Input {
	private $_translation;
	private $_key;

	private function makeTranslation() {
		$check = getCheck();
		if ($check = true) {
			$this->_key = array_search(getInput(), Library::$_translators);
			$this->_translation = Library::$_translations["{$key}"];
		}	else {
				try {
					throw new Exception("fuuu");
				}	catch(Exception $e) {
						echo $e->getMessage();
					}
			}
	}

	protected function getTranslation() {
		return $this->_translation;
	}
}



final class Output extends Translation {
	private $_trans_output;

	public function makeTranslation() {
		parent::makeTranslation();
		$this->_trans_output = parent::getTranslation();
	}


	public function getTranslation() {
		return $this->_trans_output;
	}

}
