Query string in php code

Question

How to put the querystring name in php?

$file_get_html('http://localhost/search/?q=');

And when accessing localhost/?name=example the code looks like this

$file_get_html('http://localhost/search/?q=example');

I do not know how to put $_GET['url'] inside a php :(

• user1864610: file_get_html($_GET['url']); - if that's really what you mean.
• Barmar: There's no $ before file_get_html
• Barmar: The question isn't very clear. Are you trying to merge the query string you received with some other URL?
• Mike Brant: I am not following what you want. What does a parameter of URL have to do with the parameter q that you are showing? can you better explain what is is you are trying to do?
• Theus: <?php // setup require_once('simple_html_dom.php'); // get DOM from URL or file $html = $file_get_html('http://localhost/serarch/?q='); ?> Wanna use the Simple HTML DOM Parser to extract data of a page. However, this page is a result of seek. So, I replace the variable in my url, the site url [search].

Answer 1

The question isn't very clear, but I suspect this is the answer:

file_get_html('http://localhost/search/?q=' . urlencode($_GET['url']));

• Theus: Notice: Undefined variable: file_get_html in C:_server\htdocs\test.php on line 7 Fatal error: Function name must be a string in C:_server\htdocs\test.php on line 7 line 7: $html = $file_get_html('http://localhost/bsearch/?q=' . urlencode($_GET['movie']));
• Barmar: Didn't you see the comment I wrote an hour ago? There shouldn't be a $ before file_get_html().
• Theus: Oh, sorry. Worked. I thought the $ in front of file_get_html was standard for extension
• Barmar: $ is for variables in PHP, I don't know where you got the idea it had anything to do with extensions.
• Theus: Although I know very little PHP, I know that the $ is all PHP variables. However, I thought it was necessary for the extension to work $. Anyway.

Answer 2

The ?q=example will let you use something like $example = $_GET['q'], and $example should equal the value of q in your querystring.

If you have a querystring that looks like this:

?q=example&url=myurl.com

You can access the q and url parameters like this:

$q = $_GET['q']; // which will equal 'example'
$url = $_GET['url']; // which will equal 'myurl.com'

If that is what you are trying to do.

• Theus: But how to put in $file_get_html?

Answer 3

$url = urlencode($_GET['url']);
$contents = file_get_contents("http://localhost/search/?q={$url}");
var_dump($contents);
