I have url in the following types
http://domain.com/1/index.php
http://domain.com/2/index.php
http://domain.com/3/index.php
http://domain.com/4/index.php
I need to retrieve only the number from the url .
for example,
when i visit http://domain.com/1/index.php , It must return 1.
Have a look at parse_url.
$url = parse_url('http://domain.com/1/index.php');
EDIT: Take a look at $_SERVER['REQUEST_URI'], to get the current URL. Use that instead of $url['path'].
Then you can split $url['path'] on /, and get the 1st element.
// use trim to remove the starting slash in 'path'
$path = explode('/', trim($url['path'], '/'));
$id = $path[0]; // 1
Given the information provided, this will do what you ask... it's not what I would call a robust solution:
$url = $_SERVER['PATH_INFO']; // e.g.: "http://domain.com/1/index.php";
$pieces = explode("/", $url);
$num = $pieces[3];
split the server path by forward slashes (explode('/', $_SERVER['REQUEST_PATH']);)
remove empty entry from the beginning
take the first element
make sure it is an integer (intval(), or a simple (int) cast).
No need to use regular expressions for this.
You use preg_match() to match the domain and get the 1st segment.
$domain = http://www.domain.com/1/test.html
preg_match("/http:\/\/.*\/(.*)\/.*/", "http://www.domain.com/1/test.html");
echo $matches[1]; // returns the number 1 in this example.

I've a PHP file. In this file I need to check, if my URL has the following ending:
www.example.de/dashboard/2/
So the ending can be a number 1 - 99+ which is always at the end of the url between two slashes. I can't use $_GET here. If it is $_GET, it would be easy:
if ( isset($_GET['ending']) ) :
So how can I do this without a parameter in the URL? Thanks for your help!
if(preg_match('^\/dashboard\/(\d+)', $_SERVER['REQUEST_URI'])){
foo();
}
Use regular expression on the request uri
You can make use of parse_url and explode:
$url = 'http://www.example.de/dashboard/2/';
$path = parse_url($url, PHP_URL_PATH); // '/dashboard/2/'
$parts = explode('/', $path); // ['', 'dashboard', '2', '']
$section = $parts[1]; // 'dashboard'
$ending = $parts[2]; // '2'
Demo: https://3v4l.org/dv6Cn
You can also make use of URL rewriting (this is for a Apache-based web server, but you can find simular resources for nginx or any other web servers if need be).
A more dynamic way is to explode and use array_filter to remove empty values then pick the last item.
If the item * 1 is the same as the item then we know it's a number.
(The return from explode is strings so we cant use is_int)
$url = "http://www.example.de/dashboard/2/";
$parts = array_filter(explode("/", $url));
$ending = end($parts);
if($ending*1 == $ending) echo $ending; //2
First you need to target this url to script - in web server config. For nginx and index.php:
try_files $uri #rewrite_location;
location #rewrite_location {
rewrite ^/(.*) /index.php?link=$1&$args last;
}
Second - you need to parse URI. In $end you find what you want
$link_as_array = array_values(array_diff(explode("/", $url), array('')));
$max = count($link_as_array) - 1;
$end = $link_as_array[$max];
I would think this way. If the URL is always the same, or the same format, I'll do the following:
Check for the approx URL.
Split the URL into pieces.
Find if there's the part I am looking for.
Extract the number.
<?php
$url = "http://www.example.de/dashboard/2/";
if (strpos($url, "www.example.de/dashboard") === 7 or strpos($url, "www.example.de/dashboard") === 8) {
$urlParts = explode("/", $url);
if (isset($urlParts[4]) && isNumeric($urlParts[4]))
echo "Yes! It is {$urlParts[4]}.";
}
?>
The strpos with 7 and 8 is for URL with http:// or https://.
The above will give you the output as the numeric part if it is set. I hope this works out.
I have below URL in my code and i want to split it and get the number from it
For example from the below URL need to fetch 123456
https://review-test.com/#/c/123456/
I have tried this and it is not working
$completeURL = https://review-test.com/#/c/123456/ ;
list($url, $number) = explode('#c', preg_replace('/^.*\/+/', '', $completeURL));
Use parse_url
It's specifically made for this sort of thing.
You can do this without using regex also -
$completeURL = 'https://review-test.com/#/c/123456/' ;
list($url, $number) = explode('#c', str_replace('/', '', $completeURL));
echo $number;
If you wan to get the /c/123456/ params you will need to execute the following:
$url = 'https://review-test.com/#/c/123456/';
$url_fragment = parse_url($url, PHP_URL_FRAGMENT);
$fragments = explode('/', $url_fragment);
$fragments = array_filter(array_map('trim', $fragments));
$fragments = array_values($fragments);
The PHP_URL_FRAGMENT will return a component of the url after #
After parse_url you will end up with a string like this: '/c/123456/'
The explode('/', $url_fragment); function will return an array with empty indexes where '/' was extracted
In order to remove empty indexes array_filter($fragments); the
array_map with trim option will remove excess spaces. It does not
apply in this case but in real case scenario you better trim.
Now if you var_dump the result you can see that the array needs to
be reindexed array_values($fragments)
You should try this: basename
basename — Returns trailing name component of path
<?php
echo basename("https://review-test.com/#/c/123456/");
?>
Demo : http://codepad.org/9Ah83qaP
Subsequently you can directly take from pure regex to fetch numbers from string,
preg_match('!\d+!', "https://review-test.com/#/c/123456/", $matches);
print_r($matches);
Working demo
Simply:
$tmp = explode( '/', $completeUrl).end();
It will explode the string by '/' and take the last element
If you have no other option than regex, for your example data you could use preg_match to split your url instead of preg_replace.
An approach could be to
Capture the first part as a group (.+\/)
Then capture your number as a group (\d+)
Followed by a forward slash at the end of the line \/$/
This will take the last number from the url followed by a forward slash.
Then you could use list and skip the first item of the $matches array because that will contain the text that matched the full pattern.
$completeURL = "https://review-test.com/#/c/123456/";
preg_match('/(.+\/)(\d+)\/$/', $completeURL, $matches);
list(, $url, $number) = $matches;
Well sorry for the probably misleading title. Wasn't sure how to describe it better.
When accessing the status page I want to get the attached ID. But I don't want to use GET fields (wordpress makes /status?id=2134 to /status/?id=1234 - that's the only reason actually).
So this is my url
http://foo.bar.com/status/1234/
I want to get 1234
Okay fine. I could use something like $_SERVER["REQUEST_URI"] + trim() for example. Probably regex would be the key to get this job done since one could do something like /status/1234/foo/bar/baz/.. But I'm wondering if there is something builtin with PHP to get this part of the url.
Use the parse_url() function, and extract it:
$url = 'http://foo.bar.com/status/1234/';
$path = trim(parse_url($url, PHP_URL_PATH), '/');
$items = explode('/', $path);
$num = array_pop($items);
var_dump($num);
You can also use a regular expression, if that tickles your fancy:
$url = 'http://foo.bar.com/status/1234/';
$path = parse_url($url, PHP_URL_PATH);
preg_match('~/status/(?P<num>\d+)/?~', $path, $result);
$num = isset($result['num']) ? $result['num'] : null;
var_dump($num);
Try to parses a URL and returns an associative array containing any of the various components of the URL that are present using parse_url, explode it using explode and finally select status id using end
Try like this
$url = 'http://foo.bar.com/status/1234/';
$statusId = explode('/',trim(parse_url($url, PHP_URL_PATH), '/'));
print end($statusId);

I am not much used to using rtrim and Reg expressions. So I wanted to get my doubt cleared about this:
Here is a url: http://imgur.com/r/pics/paoWS
I am trying to use rtrim function on this url to pick out only the 'paoWs' from the whole url.
Here is what i tried:
$yurl = 'http://imgur.com/r/pics/paoWS';
$video_id = parse_url($yurl, PHP_URL_PATH);
$yid=rtrim( $video_id, '/' );
And i am using '$yid' to hotlink the image from imgur. But What I get after trying this function is:
$yid= '/r/pics/paoWS'
How do I solve this?
rtrim is used for trimming down a string of certain characters or whitespace on the right-hand side. It certainly shouldn't be used for your purpose.
Assuming the URL structure will always be the same, you could just do something like this:
$yurl = 'http://imgur.com/r/pics/paoWS';
$video_id = parse_url($yurl, PHP_URL_PATH);
$parts = explode('/', $video_id)
$yid = end($parts);
You sould not use regular expressions (whitch are 'expensive') for a so 'simple' problem.
If you want to catch the last part of the URL, after the last slash, you can do :
$urlParts = explode('/', 'http://imgur.com/r/pics/paoWS');
$lastPart = end($urlParts);
rtim( strrchr('http://imgur.com/r/pics/paoWS' , '/') ); rtrim + strrchr
substr(strrchr('http://imgur.com/r/pics/paoWS', "/"), 1); substr + strrchr
rtrim() returns the filtered value, not the stripped characters. And your usage of it isn't proper too - it strips the passed characters from the right side. And you don't need parse_url() either.
Proper answers have been given already, but here's a faster alternative:
$yid = substr($yurl, strrpos($yurl, '/')+1);
Edit: And another one:
$yid = ltrim(strrchr($yurl, '/'), '/');
i have this URI.
http://localhost/index.php?properties&status=av&page=1
i am fetching basename of the URI using following code.
$basename = basename($_SERVER['REQUEST_URI']);
the above code gives me following string.
index.php?properties&status=av&page=1
i would want to remove the last variable from the string i.e &page=1. please note the value for page will not always be 1. keeping this in mind i would want to trim the variable this way.
Trim from the last position of the string till the first delimiter i.e &
Update :
I would like to remove &page=1 from the string, no matter in which position it is on.
how do i do this?
Instead of hacking around with regular expression you should parse the string as an url (what it is)
$string = 'index.php?properties&status=av&page=1';
$parts = parse_url($string);
$queryParams = array();
parse_str($parts['query'], $queryParams);
Now just remove the parameter
unset($queryParams['page']);
and rebuild the url
$queryString = http_build_query($queryParams);
$url = $parts['path'] . '?' . $queryString;
There are many roads that lead to Rome. I'd do it with a RegEx:
$myString = 'index.php?properties&status=av&page=1';
$myNewString = preg_replace("/\&[a-z0-9]+=[0-9]+$/i","",$myString);
if you only want the &page=1-type parameters, the last line would be
$myNewString = preg_replace("/\&page=[0-9]+/i","",$myString);
if you also want to get rid of the possibility that page is the only or first parameter:
$myNewString = preg_replace("/[\&]*page=[0-9]+/i","",$myString);
Thank you guys but i think i have found the better solution, #KingCrunch had suggested a solution i extended and converted it into function. the below function can possibly remove or unset any URI variable without any regex hacks being used. i am posting it as it might help someone.
function unset_uri_var($variable, $uri) {
$parseUri = parse_url($uri);
$arrayUri = array();
parse_str($parseUri['query'], $arrayUri);
unset($arrayUri[$variable]);
$newUri = http_build_query($arrayUri);
$newUri = $parseUri['path'].'?'.$newUri;
return $newUri;
}
now consider the following uri
index.php?properties&status=av&page=1
//To remove properties variable
$url = unset_uri_var('properties', basename($_SERVER['REQUEST_URI']));
//Outputs index.php?page=1&status=av
//To remove page variable
$url = unset_uri_var('page', basename($_SERVER['REQUEST_URI']));
//Outputs index.php?properties=&status=av
hope this helps someone. and thank you #KingKrunch for your solution :)
$pos = strrpos($_SERVER['REQUEST_URI'], '&');
$url = substr($_SERVER['REQUEST_URI'], 0, $pos - 1);
Documentation for strrpos.
Regex that works on every possible situation: /(&|(?<=\?))page=.*?(?=&|$)/. Here's example code:
$regex = '/(&|(?<=\?))page=.*?(?=&|$)/';
$urls = array(
'index.php?properties&status=av&page=1',
'index.php?properties&page=1&status=av',
'index.php?page=1',
);
foreach($urls as $url) {
echo preg_replace($regex, '', $url), "\n";
}
Output:
index.php?properties&status=av
index.php?properties&status=av
index.php?
Regex explanation:
(&|(?<=\?)) -- either match a & or a ?, but if it's a ?, don't put it in the match and just ignore it (you don't want urls like index.php&status=av)
page=.*? -- matches page=[...]
(?=&|$) -- look for a & or the end of the string ($), but don't include them for the replacement (this group helps the previous one find out exactly where to stop matching)
You could use a RegEx (as Chris suggests) but it's not the most efficient solution (lots of overhead using that engine... it's easy to do with some string parsing:
<?php
//$url="http://localhost/index.php?properties&status=av&page=1";
$base=basename($_SERVER['REQUEST_URI']);
echo "Basename yields: $base<br />";
//Find the last ampersand
$lastAmp=strrpos($base,"&");
//Filter, catch no ampersands found
$removeLast=($lastAmp===false?$base:substr($base,0,$lastAmp));
echo "Without Last Parameter: $removeLast<br />";
?>
The trick is, can you guarantee that $page will be stuck on the end? If it is - great, if it isn't... what you asked for may not always solve the problem.
