passing of parameters

rougue

Im not sure how to phrase this but here goes:

how do i access variables passed to the php script from the address line such as

mypage.php?id=5

i've tried to access directly and throught the $_POST variable but neither of those work. I looked in the php manual and i didnt find it there either so exacly how does php pass/accept external variables? Thanks in advance

anything in the url has a method of GET. use $_GET['var_name'] to access.

try this...
What this would do, parse the string at the top... like you said..

mypage.php?id=5

and it would turn "id" into a variable, with the value of "5", so you could type..
echo $id;
or whatever, and it would be the value of 5... see? EASY.


$query = $QUERY_STRING;
$query_Array = explode("&", $query);
foreach ($query_Array as $i) {
$doubleItem = explode("=", $i);
$$doubleItem[0] = str_replace("%20", " ", $doubleItem[1]);
}

BAD! BAD! 🙂 You're using register_globals, aren't you? Admit it!

Anyway, turn OFF register_globals

You would access it via $_GET array, as said above...

echo $_GET['id']; will output 5
