remove 's' from line 7

$error_array=array();

Also put a closing brace '}' on line no 47

Make sure you write $this->name and NOT $this->$name.

<html>
<head>
Creating objects
</head>
<body>
<?php
class Objects
{
	var $name;

	function set_name($na)
	{
		$this->name= $na;
	}
	
	function get_name()
	{
		return $this->name;
	}
}

$ob=new Objects;
$ob->set_name("ila");
echo "the name of greatest person alive is ",$ob->get_name();

?>
</body>

Kindly tell error in this code.

if(count($argument)==1)
			{
				$this->name=$argument[0];
			}
			if(count($argument)==2)
			{
				$this->name=$argument[0];
				$this->msg=$argument[1];
			}

Here you have not written $ sign before argument. In my previous post I suggest about position of dollar sign. So Here this->name is different then argument, so both will start with dollar sign.
