Get second argument in php navigation - php

I am trying to grab the second argument of a URL such as this:
http://website.com/?p=2?id=ass92jdskdj92
I just want the id portion of the address. I use the following code to grab the first portion of the address:
$p = $_GET[p];
$remove = strrchr($p, '?');
$p = str_replace($remove, "", $p);
Any hints on how to get the second portion?

Arguments in links are started by ? and divided by &.
That means your link should look like this:
http://website.com/?p=2&id=ass92jdskdj92
And you get them by:
$p = $_GET['p'];
$id = $_GET['id'];

First change the URL
only first argument start with ? and rest of all is append by &
u should try with
echo parse_url($url, PHP_URL_PATH);
Reference:
parse url

changing get variable using parse_url not working in php

I've looked at every post on SO that remotely pertains to this and I just can't figure this out. This code is taken directly from another SO post and was marked as the correct working answer:
$query = $_GET;
// replace parameter(s)
$query['d'] = 'new_value';
// rebuild url
$query_result = http_build_query($query);
// new link
Link
Again, taken straight from another post. When I try this code, i change the $_GET to the actual URL that i want to alter. When the code gets to the $query['d'] part, it tells me I get an illegal string offset and the error is the index that's specified. So then I parse the URL, and then do parse_str($query, $output) which in turn allows me to do $output['d'] and THEN I can set a new value to that variable. If I echo it out, it's fine.
But then I get to the http_build_query line, and it tells me that it's expecting an array or object and I can't build the new URL. Here is my code:
$link = parse_url('https://www.google.com/search?source=hp&ei=85GhW6CNHoSqsgXnzoD4Ag&q=coding+tutorial&btnK=Google+Search&oq=coding+tutorial', PHP_URL_QUERY);
parse_str($link, $output);
$output['oq'] = 'new value';
$query_result = http_build_query($link);
echo $query_result;
This code yields that the http_build_query function wants an array or object...i guess i'm not giving it that in some way? What do I need to do to get this to work?
If you want to rebuild the full URL after modifying the query parameters, you could do this:
$url = 'https://www.google.com/search?source=hp&ei=85GhW6CNHoSqsgXnzoD4Ag&q=coding+tutorial&btnK=Google+Search&oq=coding+tutorial';
$link = parse_url($url, PHP_URL_QUERY);
parse_str($link, $output);
$output['oq'] = 'new value';
echo substr($url, 0, strpos($url, '?') + 1) . http_build_query($output);
Output:
https://www.google.com/search?source=hp&ei=85GhW6CNHoSqsgXnzoD4Ag&q=coding+tutorial&btnK=Google+Search&oq=new+value

parse non encoded url

there is an external page, that passes a URL using a param value, in the querystring. to my page.
eg: page.php?URL=http://www.domain2.com?foo=bar
i tried saving the param using
$url = $_GET['url']
the problem is the reffering page does not send it encoded. and therefore it recognizes anything trailing the "&" as the beginning of a new param.
i need a way to parse the url in a way that anything trailing the second "?" is part or the passed url and not the acctual querystring.
Get the full querystring and then take out the 'URL=' part of it
$name = http_build_query($_GET);
$name = substr($name, strlen('URL='));
Antonio's answer is probably best. A less elegant way would also work:
$url = $_GET['url'];
$keys = array_keys($_GET);
$i=1;
foreach($_GET as $value) {
$url .= '&'.$keys[$i].'='.$value;
$i++;
}
echo $url;
Something like this might help:
// The full request
$request_full = $_SERVER["REQUEST_URI"];
// Position of the first "?" inside $request_full
$pos_question_mark = strpos($request_full, '?');
// Position of the query itself
$pos_query = $pos_question_mark + 1;
// Extract the malformed query from $request_full
$request_query = substr($request_full, $pos_query);
// Look for patterns that might corrupt the query
if (preg_match('/([^=]+[=])([^\&]+)([\&]+.+)?/', $request_query, $matches)) {
// If a match is found...
if (isset($_GET[$matches[1]])) {
// ... get rid of the original match...
unset($_GET[$matches[1]]);
// ... and replace it with a URL encoded version.
$_GET[$matches[1]] = urlencode($matches[2]);
}
}
As you have hinted in your question, the encoding of the URL you get is not as you want it: a & will mark a new argument for the current URL, not the one in the url parameter. If the URL were encoded correctly, the & would have been escaped as %26.
But, OK, given that you know for sure that everything following url= is not escaped and should be part of that parameter's value, you could do this:
$url = preg_replace("/^.*?([?&]url=(.*?))?$/i", "$2", $_SERVER["REQUEST_URI"]);
So if for example the current URL is:
http://www.myhost.com/page.php?a=1&URL=http://www.domain2.com?foo=bar&test=12
Then the returned value is:
http://www.domain2.com?foo=bar&test=12
See it running on eval.in.

PHP: How can i read the second part of URL

How can I take out the part of the url after the view name
Example:
The URL:
http://localhost/winner/container.php?fun=page&view=eims
Extraction
eims
This is called a GET parameter. You can get it by using
<?php
$view = $_GET['view'];
If this is for a URL which is not part of your website (e.g. Not your domain), but you wish to parse it. Something like this will work
$url = "http://example.com/index.php?foo=bar&acme=baz&view=asdf";
$params = explode('?', $url)[1]; // This gets the text AFTER the ? Note: If using PHP 5.3 or less, this may not work. You would then need to split it into two lines with the [1] happening on $params.
$pairs = explode('&', $params);
foreach($pairs as $p => $pair) {
list($keys[$p], $values[$p]) = explode('=', $pair);
$splits[$keys[$p]] = $values[$p];
}
echo $splits['view'];
<?php echo $_GET['view']; ?> //eims
If that's current URL, the simple and rock solid approach is to use the filter functions:
filter_input(INPUT_GET, 'view')
Otherwise, you can use parse_url() with PHP_URL_QUERY as second argument. The resulting string can be split with e.g. parse_str().
Are sure you are writing this "echo $_GET['view'];" in the container.php file?
Maybe write why do you need that "view".

url_title codeigniter showing underscores instead of hyphens

Hi I am trying to insert my article title in database in the following format this-is-a-new-title for the input This is a new Title. For this I have written :
$title = $this->input->post('topic_title');
$topic_slug_title = url_title($title,'-',TRUE);
But the echo $topic_slug_title shows titles like this_is_a_new_title. Why the underscores are added wherein I have given hyphens ?
Ok I found the solution. Just leave the second parameter as default,add the third parameter. That is:
$title = $this->input->post('topic_title');
$topic_slug_title = url_title($title,TRUE,TRUE);
don't use the third parameter, use it like this
$title = $this->input->post('topic_title');
$topic_slug_title = strtolower(url_title($title));
don't use second and third parameter, write like this:
**$title = $this->input->post('topic_title');
$topic_slug_title = url_title($title);**

Url Explode for value

Currently I have a url thats like this,
http://website.com/type/value
I am using
$url = $_SERVER['REQUEST_URI'];
$url = trim($url, '/');
$array = explode('/',$url);
this to get the value currently but my page has Facebook like's on it and when it is clicked it adds all these extra variables. http://website.com/type/value?fb_action_ids=1234567&fb_action_types= and that breaks that value that I am trying to get. Is there another way to get the specific value?
Assuming you know that this will always be a valid URL, you can use parse_url.
list(, $value) = explode('/', parse_url($url)['path']);
I'd use a preg_replace
explode('/', preg_replace('/?.*$/', '', $url));
You could also use:
$array = explode('/',$_SERVER['PATH_INFO']);
Or, this:
$array = explode('/',$_SERVER['PHP_SELF']);
With this, you do not need the trim() call or the temp var $url - unless you use it from something else.
The reason for two options is I don't know if /type/value is being passed to an index.php or if value is in fact a php file. Either way, one of the two options will give you what you need.
