升级到PHP 7.0.8后使用Smarty发出警告

Question

After upgrading Plesk and PHP to the version 7.0.8, I'm getting the following warning when using Smarty.

PHP Deprecated: Methods with the same name as their class will not be constructors in a future version of PHP; Smarty_Compiler has a deprecated constructor in /var/www/vhosts/mydomain.com/httpdocs/Smarty/Smarty_Compiler.class.php on line 35

Here the file mentioned in the warning:

/*
 * @link http://smarty.php.net/
 * @author Monte Ohrt <monte at ohrt dot com>
 * @author Andrei Zmievski <andrei@php.net>
 * @version 2.6.20
 * @copyright 2001-2005 New Digital Group, Inc.
 * @package Smarty
 */

/* $Id: Smarty_Compiler.class.php 2773 2008-08-12 18:17:51Z Uwe.Tews $ */

/**
 * Template compiling class
 * @package Smarty
 */
class Smarty_Compiler extends Smarty {

I need help to understand the problem and how to fix it, is it relative to Smarty or fixable on my end?

Answer 1

As of PHP 7.0.x , PHP 4 style constructors (methods that have the same name as the class they are defined in) are deprecated, and will be removed in the future. PHP 7 will emit E_DEPRECATED if a PHP 4 constructor is the only constructor defined within a class. Classes that implement a __construct() method are unaffected.

So, there's two solution:

1. You can turn off the deprecated warning message by adding this on your code: error_reporting(E_ALL ^ E_DEPRECATED);

2. Edit the Smarty_Compiler.class.php file and change the method name Smarty_Compiler() to __construct()
