I have big problem. I have some code like :
This is in my folder "country"
if($_GET[''] == 'England') {
echo 'test';
}
Is that impossible to left empty get parameter? to get url like : link.com/country/England
You can do the following: example.com/country/?England, and check if the England key exists:
if(isset($_GET['England'])) {
// Do stuff
}
Without the ? characters, it's a bit more difficult and require to rewrite URL with [mod_rewrite][1] if you're using Apache web server for example
You are looking for url rewriting: http://httpd.apache.org/docs/2.0/misc/rewriteguide.html

I would like to replace my links appeared in my page's adressbar.
Now the links have this format: http://mypage.com/index.php?page=contact
And I want this format: mypage.com/contact
How to do that?
(No links please, I need example.)
Update:
This is one possible solution that worked:
RewriteEngine on
RewriteRule ^([^/.]+)?$ index2.php?page=$1 [L]
Take a look at htaccess and mod_rewrite.
You asked for no links, so I'll let you Google them yourself.
Once you have a chosen path, try it out and if you can't get it working come back with examples of what you've tried and in what way they didn't work.

I want to make it so that if there is a ?no at the end of a url, then something does not happen. But, if there is nothing at the end of the url, then something does happen. How can I do this?
use

//something happen
} else {
//do nothing
}

How can I write a code that gets the current location coordinates (LLA) in my web browser using PHP .
Is it possible by using GPS via HTTP or something like that ?
please help
Thanks
You will need to use the brower's geolocation API, for example as shown here.
Then, you simply pass the parameters to a PHP script using whatever method you like, a form, or a jQuery post.

I am looking to create a simple url where I can add URL querys to it and then have these saved to a database.
This would be the format that i'm looking for
example.com?name=value1&email=value2
Could anybody help ?
Get the values on the script from $_GET, then put them in your database using PDO or MySQLi. I don't know your database structure so I can't really help any further:
// In index.php
echo $_GET["name"];
echo $_GET["email"];
// Put them in your database

I have this link viewdocument.php?a=http%3A%2F%2Fwww.iesalfonsox.com%2Fimages%2FLIBROS_ESO_13-14.pdf in (for example) index.php and I want to put only the URL of the document of the link.
Example:
Link: http://www.myweb.com/viewdocument.php?a=some.pdf
On the HTML: You're viewing "Some.pdf".
Do you understand? Convert "viewdocument.php?a=some.pdf" to "some.pdf".
If this is the current URL being accessed on your site, Php provide globals and you can access it using the $_GET variable:
so for your example you will use this:
$file = $_GET['a']; // will return some.pdf
The other case will be for parsing a url from a string, for which php provides a function:
parse_url();
