Question

I recently updated to PHP 5.3.6 and there were some deprecated functions and INI directives. I have the following function:

function ServerVar($varName) {
global $HTTP_SERVER_VARS;
global $HTTP_ENV_VARS;

if(!isset($_SERVER))
{
    $_SERVER = $HTTP_SERVER_VARS;
    if(!isset($_SERVER["REMOTE_ADDR"]))
        $_SERVER = $HTTP_ENV_VARS; // must be Apache
    }

if(isset($_SERVER[$varName]))
    return $_SERVER[$varName];
else
    return "";
}

Running that function caused an error in apache log:

<b>Deprecated</b>:  Directive 'register_long_arrays' is deprecated in PHP 5.3 and greater in <b>Unknown</b> on line <b>0</b><br />

I modfied the code like this:

if(!isset($_SERVER))
{
    $_SERVER = &$HTTP_SERVER_VARS;
    if(!isset($_SERVER["REMOTE_ADDR"]))
        $_SERVER = &$HTTP_ENV_VARS; // must be Apache
    }

if(isset($_SERVER[$varName]))
    return $_SERVER[$varName];
else
    return "";
}

however the the same error still appears in apache log. What is the best way to resolve this problem?

Thank you!!

In PHP 5.3 (really, I think any version of PHP 5 or later any version of PHP newer than 4.1.0) you shouldn’t ever need to use $HTTP_SERVER_VARS or $HTTP_ENV_VARS. Just use $_SERVER. If that does not work, then your server needs to have it’s configuration fixed; not code workarounds like this induced.
