How to get the last characters of a URL?

[redmike]

Hi guys!

 

I am learning PHP now and I am enjoying it. Im not an I.T. graduate that is why Im having very difficult time to understand  codes.

 

My problem is how to get the last character of a URL that I get using another php code. I can already post the URL on my page but it displays all the URL of the certain page that I get.

 

Example: the URL is "http://mysite.com/page_1/pp1/?lang=zh" I only want to get the "?lang=zh". I am working under 3 languages and I want to get only that last part of the URL for me to continue my work. I dont exactly know what string or filtering I will do to get that part only.

 

Please help me guys. I will appreciate all your comments here.

What exactly do you need that part for? There may very well be something simpler.

Use the parse url function: http://uk3.php.net/manual/en/function.parse-url.php

 

Would look like this:

 

// To print
echo parse_url($url, PHP_URL_QUERY );

// To assign
$query = parse_url($url, PHP_URL_QUERY );

echo $_GET['lang'];

Hi sir!

 

Because I have images  (that has english embedded). I also have same images that has chinese/taiwanese characters embeded.  I want to get the last part "?lang=zh" because i have code that if the URL has "lang-zh" it will get the chinese images.

 

heres my sample code that i use.

 

< ?

function curPageURL() {
$pageURL = 'http';
if ($_SERVER["HTTPS"] == "on") {$pageURL .= "s";}
$pageURL .= "://";
if ($_SERVER["SERVER_PORT"] != "80") {
  $pageURL .= $_SERVER["SERVER_NAME"].":".$_SERVER["SERVER_PORT"].$_SERVER["REQUEST_URI"]; 
} 

else {  $pageURL .= $_SERVER["SERVER_NAME"].$_SERVER["REQUEST_URI"]; }
return $pageURL;
}

$lang= curPageURL();

if ($lang=="http://www.website.com/?lang=zh-hans")	
echo "<a href=\"#\" border=\"0\"><img src=\"http://www.website.com/cn/visa-2.png\" ></a>";

elseif ($lang=="http://www.website.com/?lang=zh-hant")
echo "<a href=\"#\" border=\"0\"><img src=\"http://www.website.com/cnt/visa-3.png\" ></a>";

else 
echo "<a href=\"#\" border=\"0\"><img src=\"http://www.website.com/en/visa.png\" ></a>";
? >

 

This code is okay only under the index.php page. But when im under the inside pages it doesnt work anymore unless I manually add all the needed pages to be translated with images.

 

I have lots of pages to translate. So I think It would be more easier for me if I only get the "?lang=zh-hant" for taiwan images and "?lang=zh-hans" for chinese images.

 

Am I making it clear to you? Actually I dont know how to explain it using programmer's language but Im pretty sure Im explaining it using leighman's.

Wow this answers my problem! Thank you so much!

[redmike]

echo $_GET['lang'];

 

thanks! this also works!

 

Im so happy! 

[redmike]

I still dont know to match the URL and characters that I get after parsing. I still get the english images only...

[redmike]

Oh i see! its working now. Sorry I messed up. I use this to assign. :

 

// To assign

$query = parse_url($url, PHP_URL_QUERY );

 

thanks stuart!

The most common usage of the query string part of a url is to retrieve the part you want from within the $_GET array. Parsing the string yourself is almost always un-required.

 

I'm quite sure your going about this the wrong way.

so you mean this is wrong even if it works well on my part? I added this on the above script:

 

 

$lang= curPageURL();

$query = parse_url($lang, PHP_URL_QUERY );

 

if ($query=="lang=zh-hans")

Your going about it the long way. Whats wrong with....

 

if ($_GET['lang'] == 'zh-hans') {
  // do whatever.
}

 

Of course, you should also check lang is set first....

 

 

if (isset($_GET['lang'] && $_GET['lang'] == 'zh-hans') {
  // do whatever.
}

 

This is why I asked what exactly you where planning on doing with the data in my first reply. There really is no need to parse the url yourself.

[AbraCadaver]

Yes, in this case I can't see that the curPageURL() function is needed at all.  Maybe it's used somewhere else in your script, but here it is useless:

 

if(isset($_GET['lang'])) {
   switch($_GET['lang']) {
      case 'zh-hans':
         echo "<a href=\"#\" border=\"0\"><img src=\"/cn/visa-2.png\" ></a>";
         break;

      case 'zh-hant':
         echo "<a href=\"#\" border=\"0\"><img src=\"/cnt/visa-3.png\" ></a>";
         break;

      default:
         echo "<a href=\"#\" border=\"0\"><img src=\"/en/visa.png\" ></a>";
         break;
   }
}

 

If you do this frequently, then you'll probably have better luck by doing this check at the top of the page, maybe in a header file and then assigning the language to a session var to be used later.

Your missing the closing parethisis for the isset on your code.

I tried this one and yes its working only in "zh-hant" and zh-hans". But the default displays nothing. That is why I think parsing the url works well. 

 

I dont know how to make the default works. Is it maybe because Im using includes instead of echo to display everything?

 

 

I understand yes, curPageURL() function doesn't do anything here. I didnt use it anywhere too. But I find more useful that the "_GET".

 

if(isset($_GET['lang'])) {
   switch($_GET['lang']) {
      case 'zh-hans':
         	include (TEMPLATEPATH . '/branches-cn.php');  //branches pages contains the translated images
         break;

      case 'zh-hant':
        	include (TEMPLATEPATH . '/branches-tcn.php'); 
         break;

      default:
         include (TEMPLATEPATH . '/branches.php'); //This is my english page 
         break;
   }
}

 

Is there something missing here? Why is the english images not displayed?

try

if(isset($_GET['lang'])) {
   switch($_GET['lang']) {
      case 'zh-hans':
         	include (TEMPLATEPATH . '/branches-cn.php');  //branches pages contains the translated images
         break;

      case 'zh-hant':
        	include (TEMPLATEPATH . '/branches-tcn.php'); 
         break;

      default:
         include (TEMPLATEPATH . '/branches.php'); //This is my english page 
         break;
   }
} else  include (TEMPLATEPATH . '/branches.php');

[redmike]

try

if(isset($_GET['lang'])) {
   switch($_GET['lang']) {
      case 'zh-hans':
         	include (TEMPLATEPATH . '/branches-cn.php');  //branches pages contains the translated images
         break;

      case 'zh-hant':
        	include (TEMPLATEPATH . '/branches-tcn.php'); 
         break;

      default:
         include (TEMPLATEPATH . '/branches.php'); //This is my english page 
         break;
   }
} else  include (TEMPLATEPATH . '/branches.php');

 

Great! this works!

[AbraCadaver]

try

if(isset($_GET['lang'])) {
   switch($_GET['lang']) {
      case 'zh-hans':
         	include (TEMPLATEPATH . '/branches-cn.php');  //branches pages contains the translated images
         break;

      case 'zh-hant':
        	include (TEMPLATEPATH . '/branches-tcn.php'); 
         break;

      default:
         include (TEMPLATEPATH . '/branches.php'); //This is my english page 
         break;
   }
} else  include (TEMPLATEPATH . '/branches.php');

 

Good catch.
