	$var=1;
}
?>

INVOKED BY THIS SCRIPT

(Toggle Plain Text)

//SCRIPT NAME=hello.php
<?php
       include ("evalcls.inc");
       $oj= new evalcls();
?>

when i run this script i get this error;

(Toggle Plain Text)

Parse error: parse error, unexpected T_VARIABLE, expecting T_FUNCTION in C:\wamp\www\evalcls.inc on line 4

I am using the WAMP 5 tool as my main tool and i am writing the scripts with the crimson editor.

any help would be greately appreciated.

(Toggle Plain Text)

<?php
  class foo
  {
    $something = 1;
    function __construct()
    {}
  }
  $f = new foo();
?>

yielded the same as yours, but this worked:

(Toggle Plain Text)

<?php
  class foo
  {
    public $something = 1;
    function __construct()
    {

    }
  }
  $f = new foo();
?>

Maybe PHP now requires access modifiers for variables?

Class members must be defined with public, private, or protected.

From the manual:

Note: The PHP 4 method of declaring a variable with the var keyword is still supported for compatibility reasons (as a synonym for the public keyword). In PHP 5 before 5.1.3, its usage would generate an E_STRICT warning.

(Toggle Plain Text)

Parse error: parse error, unexpected T_IF, expecting T_FUNCTION in C:\wamp\www\evalcls.inc on line 5

I believe the only change you need to make to your code is as follows:

(Toggle Plain Text)

class evalcls {
	var $foo = 1;
}

Where foo can be whatever name you choose for the variable, but I do believe the var keyword needs to be included rather than $var as you were doing before. Or as Jimbo stated placing the access type of the variable (public/private). So an alternate way might be:

(Toggle Plain Text)

class evalcls {
	public $foo;
	function __construct() {
        	$this->foo = 1;
	}
}

Which will give your variable the necessary value upon its construction. I assumed you'd declared it as public 'cause you want to modify it somehow.

grimpirate · Oct 24th, 2006, 4:45 PM

Is that code located in your class or where exactly? 'Cause it wouldn't make sense to declare it as public if it's not in a class, which is what might be producing the error.

kruptof · Oct 24th, 2006, 4:54 PM

sorry i should it made clear. that code is part of the class.

thanks.

kruptof · Oct 24th, 2006, 4:57 PM
