PHP - Function eregi() is deprecated error message.

Hi,
I am receiving the following error message.

Deprecated: Function eregi() is deprecated in /home/mywebsit/public_html/includes/functions.php on line 262

How should I recode the code below to correct the error?


$GP_uploadAction = $HTTP_SERVER_VARS['PHP_SELF'];
if (isset($HTTP_SERVER_VARS['QUERY_STRING'])) {
  if (!eregi("GP_upload=true", $HTTP_SERVER_VARS['QUERY_STRING'])) {
            $GP_uploadAction .= "?".$HTTP_SERVER_VARS['QUERY_STRING']."&GP_upload=true";
      } else {
            $GP_uploadAction .= "?".$HTTP_SERVER_VARS['QUERY_STRING'];
      }
} else {
  $GP_uploadAction .= "?"."GP_upload=true";
}

you can use stripos as no wildcard is in your regexp and thus no regular expression needed. Also replace the HTTP- long array as they are gone wiht php 5.4. THis code works without warning on php 5.4

$GP_uploadAction = $_SERVER['PHP_SELF'];
if (isset($_SERVER['QUERY_STRING'])) {
  if (stripos("GP_upload=true", $_SERVER['QUERY_STRING']) === false) {
            $GP_uploadAction .= "?".$_SERVER['QUERY_STRING']."&GP_upload=true";
      } else {
            $GP_uploadAction .= "?".$_SERVER['QUERY_STRING'];
      }
} else {
  $GP_uploadAction .= "?"."GP_upload=true";
}

For PHP developers, the PHP.net web site is an invaluable resource.  If you are upgrading to PHP 5.4, you really need to read this:
http://php.net/migration54

On that page you will also find a line with the links for the other recent upgrade paths.  It says something like this:
See also the migration guides for PHP versions 5.0.x, 5.1.x, 5.2.x and 5.3.x.

The migration guides explain what is deprecated and what is removed, as well as what is added in each new release of PHP.
