URL to variable

[netrepsa]

Does any one know how to run variables in URL into a file.

ie.

url = http://sales.sewforprofit.com/index.php?email=[e-mail]

in the index.php file I would like to use the variable $email to retrieve the record from the datatable where the email field = the variable $email.

if the variable is attached to the URL it's called a GET variable, so you can access it in your index.php file by referring to $_GET['email']

If your global variables are turned on though, you can just refer to $email and you'll get a value for it.

You just then have to build the code around it to do what you want with the variable, now you know how to access it. And darn me if that isn't the fun part :p

The function parse_url($url) will split the url up, and give you access to the individual values:
Snip from php.net

$ php -r 'print_r( parse_url("http://username:password@hostname/path?arg=value#anchor"));'
Array
(
    [scheme] => http
    [host] => hostname
    [user] => username
    [pass] => password
    [path] => /path
    [query] => arg=value
    [fragment] => anchor
)

$ php -r 'print_r( parse_url("http://invalid_host..name/"));'
Array
(
    [scheme] => http
    [host] => invalid_host..name
    [path] => /
)
