PHP (Classes): "Missing argument 1 for myclass"

[nospoon]

a PHP n00b here, having a little trouble, and can not seem to understand why this message is generating:

Warning: Missing argument 1 for myclass() in C:\Program Files\xampp\htdocs\class.php on line 5

1:  <?php
2: 
3:	 class myClass
4:	 {
5:		function myClass( $x )
6:		{
7:		   $this->setName( $x );
8:		}
9:
10:	  function setName( $n )
11:	  {
12:		 $this->name = $n;
13:	  }
14:
15:	  function getName()
16:	  {
17:		 return $this->name;
18:	  }
19:
20:	  function displayMessage()
21:	  {
22:		 echo "Hello!  My name is ".$this->getName().'.';
23:	  }
24:
25:	  var $name = "Matt";
26:   }
27:
28:	 $mc = new myClass();
29:	 $mc->displayMessage();
30:
31:	 echo "<br>";
32:   $mc->setName( "Julie" );
33:   $mc->displayMessage();
34:
35:   ?>

Full output was:

Warning: Missing argument 1 for myclass() in C:\Program Files\xampp\htdocs\class.php on line 5

Hello! My name is .

Hello! My name is Julie.

Thanks

No one knows? It should be an easy one for those seasoned PHPers

Nevermind I figured it out. Stepped away from C/C++ for a year and my brain is mush. Handy tip, always keep some sort of project ongoing to keep it fresh!

well, for those who come across this later...

it's because he instantiated the class, but the constructor wanted an argument and he didn't specify a default one.

one easy fix would be

function myClass( $x = "" )

That way, if you don't specify an argument to pass, it SHOULD then see that it's defined in the function already.
