How to remove the querystring and get only the URL? - php

Question

I'm using PHP to build the URL of the current page. Sometimes, URLs in the form of
www.example.com/myurl.html?unwantedthngs
are requested. I want to remove the ? and everything that follows it (querystring), such that the resulting URL becomes:
www.example.com/myurl.html
My current code is this:
<?php
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;
}
?>

Answer 1

You can use strtok to get string before first occurence of ?
$url = strtok($_SERVER["REQUEST_URI"], '?');
strtok() represents the most concise technique to directly extract the substring before the ? in the querystring. explode() is less direct because it must produce a potentially two-element array by which the first element must be accessed.
Some other techniques may break when the querystring is missing or potentially mutate other/unintended substrings in the url -- these techniques should be avoided.
A demonstration:
$urls = [
'www.example.com/myurl.html?unwantedthngs#hastag',
'www.example.com/myurl.html'
];
foreach ($urls as $url) {
var_export(['strtok: ', strtok($url, '?')]);
echo "\n";
var_export(['strstr/true: ', strstr($url, '?', true)]); // not reliable
echo "\n";
var_export(['explode/2: ', explode('?', $url, 2)[0]]); // limit allows func to stop searching after first encounter
echo "\n";
var_export(['substr/strrpos: ', substr($url, 0, strrpos( $url, "?"))]); // not reliable; still not with strpos()
echo "\n---\n";
}
Output:
array (
0 => 'strtok: ',
1 => 'www.example.com/myurl.html',
)
array (
0 => 'strstr/true: ',
1 => 'www.example.com/myurl.html',
)
array (
0 => 'explode/2: ',
1 => 'www.example.com/myurl.html',
)
array (
0 => 'substr/strrpos: ',
1 => 'www.example.com/myurl.html',
)
---
array (
0 => 'strtok: ',
1 => 'www.example.com/myurl.html',
)
array (
0 => 'strstr/true: ',
1 => false, // bad news
)
array (
0 => 'explode/2: ',
1 => 'www.example.com/myurl.html',
)
array (
0 => 'substr/strrpos: ',
1 => '', // bad news
)

Use PHP Manual - parse_url() to get the parts you need.
Edit (example usage for #Navi Gamage)
You can use it like this:
<?php
function reconstruct_url($url){
$url_parts = parse_url($url);
$constructed_url = $url_parts['scheme'] . '://' . $url_parts['host'] . $url_parts['path'];
return $constructed_url;
}
?>
Edit (second full example):
Updated function to make sure scheme will be attached and none notice msgs appear:
function reconstruct_url($url){
$url_parts = parse_url($url);
$constructed_url = $url_parts['scheme'] . '://' . $url_parts['host'] . (isset($url_parts['path'])?$url_parts['path']:'');
return $constructed_url;
}
$test = array(
'http://www.example.com/myurl.html?unwan=abc',
`http://www.example.com/myurl.html`,
`http://www.example.com`,
`https://example.com/myurl.html?unwan=abc&ab=1`
);
foreach($test as $url){
print_r(parse_url($url));
}
Will return:
Array
(
[scheme] => http
[host] => www.example.com
[path] => /myurl.html
[query] => unwan=abc
)
Array
(
[scheme] => http
[host] => www.example.com
[path] => /myurl.html
)
Array
(
[scheme] => http
[host] => www.example.com
)
Array
(
[path] => example.com/myurl.html
[query] => unwan=abc&ab=1
)
This is the output from passing example URLs through parse_url() with no second parameter (for explanation only).
And this is the final output after constructing URL using:
foreach($test as $url){
echo reconstruct_url($url) . '<br/>';
}
Output:
http://www.example.com/myurl.html
http://www.example.com/myurl.html
http://www.example.com
https://example.com/myurl.html

Answer 3

best solution:
echo parse_url($_SERVER['REQUEST_URI'], PHP_URL_PATH);
No need to include your http://example.com in your <form action=""> if you're submitting a form to the same domain.

Answer 4

$val = substr( $url, 0, strrpos( $url, "?"));

Answer 5

Most Easiest Way
$url = 'https://www.youtube.com/embed/ROipDjNYK4k?rel=0&autoplay=1';
$url_arr = parse_url($url);
$query = $url_arr['query'];
print $url = str_replace(array($query,'?'), '', $url);
//output

Answer 6

You'll need at least PHP Version 5.4 to implement this solution without exploding into a variable on one line and concatenating on the next, but an easy one liner would be:
$_SERVER["HTTP_HOST"].explode('?', $_SERVER["REQUEST_URI"], 2)[0];

Answer 7

You can use the parse_url build in function like that:
$baseUrl = $_SERVER['SERVER_NAME'] . parse_url($_SERVER['REQUEST_URI'], PHP_URL_PATH);

Answer 8

You can try:
<?php
$this_page = basename($_SERVER['REQUEST_URI']);
if (strpos($this_page, "?") !== false) $this_page = reset(explode("?", $this_page));
?>

Answer 9

If you want to get request path (more info):
echo parse_url($_SERVER["REQUEST_URI"])['path']
If you want to remove the query and (and maybe fragment also):
function strposa($haystack, $needles=array(), $offset=0) {
$chr = array();
foreach($needles as $needle) {
$res = strpos($haystack, $needle, $offset);
if ($res !== false) $chr[$needle] = $res;
}
if(empty($chr)) return false;
return min($chr);
}
$i = strposa($_SERVER["REQUEST_URI"], ['#', '?']);
echo strrpos($_SERVER["REQUEST_URI"], 0, $i);

Answer 10

could also use following as per the php manual comment
$_SERVER['REDIRECT_URL']
Please note this is working only for certain PHP environment only and follow the bellow comment from that page for more information;
Purpose: The URL path name of the current PHP file, path-info is N/A
and excluding URL query string. Includes leading slash.
Caveat: This is before URL rewrites (i.e. it's as per the original
call URL).
Caveat: Not set on all PHP environments, and definitely only ones with
URL rewrites.
Works on web mode: Yes
Works on CLI mode: No

Answer 11

explode('?', $_SERVER['REQUEST_URI'])[0]

Answer 12

To remove the query string from the request URI, replace the query string with an empty string:
function request_uri_without_query() {
$result = $_SERVER['REQUEST_URI'];
$query = $_SERVER['QUERY_STRING'];
if(!empty($query)) {
$result = str_replace('?' . $query, '', $result);
}
return $result;
}

Answer 13

Because I deal with both relative and absolute URLs, I updated veritas's solution like the code below.
You can try yourself here: https://ideone.com/PvpZ4J
function removeQueryStringFromUrl($url) {
if (substr($url,0,4) == "http") {
$urlPartsArray = parse_url($url);
$outputUrl = $urlPartsArray['scheme'] . '://' . $urlPartsArray['host'] . ( isset($urlPartsArray['path']) ? $urlPartsArray['path'] : '' );
} else {
$URLexploded = explode("?", $url, 2);
$outputUrl = $URLexploded[0];
}
return $outputUrl;
}

Answer 14

Assuming you still want to get the URL without the query args (if they are not set), just use a shorthand if statement to check with strpos:
$request_uri = strpos( $_SERVER['REQUEST_URI'], '?' ) !== false ? strtok( $_SERVER["REQUEST_URI"], '?' ) : $_SERVER['REQUEST_URI'];

Answer 15

Try this
$url_with_querystring = 'www.example.com/myurl.html?unwantedthngs';
$url_data = parse_url($url_with_querystring);
$url_without_querystring = str_replace('?'.$url_data['query'], '', $url_with_querystring);

Answer 16

Try this:
$urrl=$_SERVER['HTTP_HOST'] . $_SERVER['SCRIPT_NAME']
or
$urrl=$_SERVER['HTTP_HOST'] . $_SERVER['PHP_SELF']
