It seems that plugin_url() cannot be used in classes. This causes an error.

<?php
/*
 * Plugin Name: plugins_url
 * Description: This demonstrates plugins_url() causes an error used in a class definition.
 * Version: 1.0
 * Author: teno
 */

class SampleClass {
    $url = plugins_url('test.php', __FILE__); 
}
?>

I need to define the file url in a class. The file is located in the plugin folder. Any solution?

why don't you define it outside the class ? – amit Aug 19 '12 at 8:24
do you mean create a global variable? Is that clean? – Teno Aug 19 '12 at 8:27
This is a problem of php. stackoverflow.com/questions/320009/… Functions defined outside a class cannot be used from inside the class. – Teno Aug 19 '12 at 8:45
This is wrong, you can use plugins_url() in any class. The question you linked to has nothing to do with your problem. Your code is just a syntax error: you cannot use a function for a variable definition. – toscho♦ Aug 19 '12 at 22:47
I think it's possible to use a function for a variable definition. Properties 'in a class' cannot be defined with a function call. Then it's a problem of php syntax. – Teno Aug 20 '12 at 3:16
