PHP5 with old PHP4 code

Question

My friend wants me to tweak his website. But I'm getting the errors

Deprecated: Assigning the return value of new by reference is deprecated in C:\xampp\htdocs\toolmanager\toolmanager\index.php on line 7

Fatal error: Cannot re-assign auto-global variable _REQUEST in C:\xampp\htdocs\toolmanager\toolmanager\includes\classloader_platform.php on line 154

when I try to run the code on apache with PHP5. Here's the code:

        require("includes/classloader_platform.php");
line 7->$classloader =& NEW classloader('0','30',$_GET,'1');
        $classloader->initialize($classloader);

line 154-> function __construct($cache=false,$cache_lifecycle=false,$_REQUEST,$template_parser=false) {
           ini_set("memory_limit","200M");
           //globalize _REQUEST
           $this->_REQUEST=$_REQUEST;
...

I think it's because he wrote it by PHP4 standards so would it be better to switch apache to PHP4 or are there some simple fixes for these errors?

rename your local $_REQUEST in the constructor to some other things — Alvin Wong

Do not revert to PHP 4. It is old and unsupported.

For "Deprecated: Assigning the return value of new by reference", just remove the &. It's redundant.

$classloader = NEW classloader(...);

For "Fatal error: Cannot re-assign auto-global variable", rename the function argument $_REQUEST to something else such as $REQUEST, then rename the subsequent occurrences of it within the function. You can't have a function argument with the same name as a superglobal.

function __construct($cache=false,$cache_lifecycle=false,$REQUEST,$template_parser=false) {
    // ...
    $this->_REQUEST=$REQUEST;
    // ...

That worked but now I'm getting "Fatal error: Call to undefined function apc_fetch()" from this: "$hits=apc_fetch("_STATS".$key);" Is apc_fetch() not supported anymore?

Wiseguy Over a year ago

apc_fetch() is still definitely part of the APC extension. Is APC enabled?

Charles Murray Over a year ago

Probably not. I looked in the "php.ini" file for ";extension=apc.so" but I couldn't find it. Is there a different way to do it?

Wiseguy Over a year ago

No, that's the way to enable it, but you probably need to compile it first. I don't think it comes in the standard distribution.

@CharlesMurray Come to think of it, if you've installed PHP via your systems package manager (e.g., apt or yum), there might simply be a php-apc package you could install instead.
