I have the following class and having difficulty accessing everything.  I only seem to be able to access one item in the array.

   class myClass {
		public static $testLinks=array(
			"first"=>array(
					"test4"=>"First option",				
					"test3"=>"Second option",
               				"test2"=>"forms/test.php",
               				"test1"=>"",
               				"list"=>"testlist.php",														
					"help"=>".this is help"),
			"second"=>array(
					"test4"=>"Choice 4",				
					"test3"=>"choice 3",
               				"test2"=>"forms/test2.php",
               				"test1"=>"",
               				"list"=>"anotherlist.php",														
					"help"=>".this is second option help"),																																																																																																																																																																																																																							
					);
			}

Open in new window


I am trying to access it  with below  (I seem to only  be able to get the list returned)

key="second";
myClass::$testLinks[$key]["list"]

Maybe start with the tutorial about PHP object-oriented programming?
http://php.net/manual/en/language.oop5.php

PHP var_dump() is your friend.  What do you want to do with this data?

Thnks for response

I thought I  tried var_dump() but will try again.

I just want to access the contents  of the class from another page.   I have the the script with the class as an include.    I want to access  "test4"  from second for example.

I'm using it to hold links, like a router.  So it looks up   the name of url that lists records, or url that display a form, or url that displays the detail record.     If you have a better suggestion I would like to hear.

There are heaps of links to go in and I thought it would be cleaner to manage from one area.  and I need good performance.  I did use a switch initially, but having the class seemed to be the better way i thought.   Appreciate input.

How far have you come with PHP object-oriented programming?  Would you be comfortable teaching it?  Or are you still learning?  Maybe if we have some reference point we can give better advice.

There's nothing wrong with your code in principal. You do have an extra comma in the array definition ()after [second][help], and you're missing the $ from the declaration of the key var. Also, you're not actually doing anything with the class property. This will work:

<?php 
error_reporting(E_ALL);
ini_set('display_errors', 1);

class myClass {
	public static $testLinks=array(
		"first"=>array(
			"test4"=>"First option",
			"test3"=>"Second option",
			"test2"=>"forms/test.php",
			"test1"=>"",
			"list"=>"testlist.php",
			"help"=>".this is help"
		),
		"second"=>array(
			"test4"=>"Choice 4",
			"test3"=>"choice 3",
			"test2"=>"forms/test2.php",
			"test1"=>"",
			"list"=>"anotherlist.php",
			"help"=>".this is second option help"
		)
	);
}

$key="second";
echo myClass::$testLinks[$key]["test4"] . PHP_EOL;
echo myClass::$testLinks[$key]["list"] . PHP_EOL;

$key="first";
echo myClass::$testLinks[$key]["test2"] . PHP_EOL;
echo myClass::$testLinks[$key]["list"] . PHP_EOL;

If you ever decide you want to be able to unit-test this, you may want to know more about this design:
