As
of February 1st we turned off register globals for
web2.unt.edu. When register globals is turned off the PHP module of
the apache server does not automatically make variables globally
accessible to the script that you are either
posting to, or using the get method and passing variables on the
command-line ie: (http://web2.unt.edu/myscript.php?first=JP&last=Williams).
The variables and values are stored in the server variable $_GET or
$_POST depending on which method you are using. What that means for
those of you that use PHP on Web2 is that when using POST or GET
methods on forms using PHP as the scripting language you will have to
extract the variables and values from the corresponding server
variable. To extract the values for the variables first and last in
the above example you will have to access them as $_GET['first'] and
$_GET['last']; or if they are posted from a form to the script
myscript.php the variable would be $_POST['first'] and $_POST['last'].
The following code snippet will fix the problem so that you will be
able to access the variables with just $first and $last.
$ArrayList = array("_GET",
"_POST", "_COOKIE", "_SERVER");
foreach($ArrayList as $gblArray){
$keys = array_keys($$gblArray);
foreach($keys as
$key){
$$key = trim(${$gblArray}[$key]);
}
}
What this little
piece of code does is cycle through the server variables and extract
the variable names and values. You can either insert this piece of
code at the top of your script or create a php file that contains just
this code and do an include in your script at the top before you try
to access the value of the variables that you passed in. To include a
file in PHP you would use the following syntax assuming that you have
a file named globalinc.php that has the above code in it:
<?
//
Include code for accessing passed variables
require("./globalinc.php");
//
Start accessing or processing passed variables
print Hello . $first;
print , how is the . $last . family?;
?>
