[php] beginner - how to $_GET from other weburl?

Hey there,

I am trying to build some kind of point system for twitter, For that i need to shorten a specific url.

this one
http://a.gd/?module=ShortURL&file=Add&mode=API&url=UNIQUE URL

How can i send and recieve the shortend url?

tried something with $_GET but not really working! Anyone got a solution?

thanks

<? 
$longurl = http://a.gd/?module=ShortURL&file=Add&mode=API&url=UNIQUE URL;
$shorturl = $_GET[$longurl];
?>

PHP:

but not working...

 

$_GET helps to retrieve the name/value parameter from an URL.
For shortening the urls may be you could use a MySql interface through which you could store an unique shortened url for each of those long urls.

example:
http://mysite.com/link1
redirects to
http://mysite.com/index.php?id=1&product=50&others=blahblah

 

Hey, you should read about fopen or curl

P.S.

Example:

<?php
$longUrl = "http://google.com";
$f = fopen ("http://a.gd/?module=ShortURL&file=Add&mode=API&url=".$longUrl, "r");
$shotUrl = fgets($f, 2000);
fclose($f);
echo $shotUrl;
?>

PHP:

 

hi

to extract the variables use this

function getVariableFromUrl($url) {		//we need to see if this URL is passing any GET variables

 	$variablesStart = strpos($url, "?") + 1;

if (!$variablesStart) {

 		// no variables!

 		return(false);

 	}

//before we extract the variables, we need to remove any anchors

$variablesEnd = strpos($url,"#",$variablesStart);

if ($variablesEnd) {

 		$getVariables = substr($url, $variablesStart, $variablesEnd - $variablesStart);

 	} else {

 		$getVariables = substr($url, $variablesStart);

 	}

//next, we split the URL into an arrays containing variable name and value pairs (ie. "variable=value")

 	$variableArray = explode("&", $getVariables);

//we will iterate through each of the array pairs (ie. "variable=value")

 	foreach ($variableArray as $arraySet) {

$nameAndValue = explode("=", $arraySet);

//using the above examples, $nameAndValue[0] would be "variable" and $nameAndValue[1] would be "value"

 		$output[$nameAndValue[0]] = $nameAndValue[1];

}

return($output);

}
$longurl = http://a.gd/?module=ShortURL&file=Add&mode=API&url=UNIQUE URL;
$shorturl = getVariableFromUrl[$longurl];
print_r($shorturl);

// or use    
//echo $shorturl[4]; 
//to print 5 element in long url

I hope that helps

May be i wrong, but i suppose, that problem is

, not in extraction variables from url...

 

please give us more description that you want. it does not matter shortened or long url. you can send url using this format:

<a href="http://www.target.com/?url=yourshortaned url">Send url</a>

now tell me what's the source of long url?

 

i suppose:
1. http://a.gd - service which makes "short url" from "long url"

http://a.gd/?module=ShortURL&file=Add&mode=API&url=LONG_URL

replace LONG_URL with real url (http://google.com) and write in browser you get a short url.

And i think need this proccess, but on php language ;-)

P.S. See my previouses posts

 

You'll need database to store the shorten URL's.

 

Are you kidding or you don't read author's post?

 

i guest like this too ...

or, maybe this (?) ->

1. you have URL = http://a.gd/?module=ShortURL&file=Add&mode=API&url=LONG_URL
2. you want to catch the LONG_URL

so, just put ->
$result = $_GET['url'];

 

i think no need use database
