Question

I have a hyperlink in my excel sheet say:

http://abc.com/u?/abc,143

When i open this link it turns out something like this:

http://abc.com/cdm4/document.php?CISOROOT=/abc&CISOPTR=160&CISOSHOW=143

I get a new number for every link. In the above example it is “160” (CISOPTR=160).

How can i extract these numbers for every link and store it?

Answer 1

Everything after .php? is usually a collection of GET request parameters. You can access them by using the global $_GET array, like so:

$myvar = $_GET['CISOPTR'];

Things to keep in mind:

1. If you are storing that data in a database remember to escape that data (use intval() for numbers and mysql_real_escape_string() for strings)
2. Do not ever trust that data – it’s a rule of thumb. This data can be malformed or maliciously modified. Always check it before doing anything with it.
