I want to add GET parameters to URLs that may and may not contain GET parameters without repeating ? or &.
Example:
If I want to add category=action
$url="http://www.acme.com";
// will add ?category=action at the end
$url="http://www.acme.com/movies?sort=popular";
// will add &category=action at the end
If you notice I'm trying to not repeat the question mark if it's found.
The URL is just a string.
What is a reliable way to append a specific GET parameter?
Basic method
$query = parse_url($url, PHP_URL_QUERY);
// Returns a string if the URL has parameters or NULL if not
if ($query) {
$url .= '&category=1';
} else {
$url .= '?category=1';
}
More advanced
$url = 'http://example.com/search?keyword=test&category=1&tags[]=fun&tags[]=great';
$url_parts = parse_url($url);
// If URL doesn't have a query string.
if (isset($url_parts['query'])) { // Avoid 'Undefined index: query'
parse_str($url_parts['query'], $params);
} else {
$params = array();
}
$params['category'] = 2; // Overwrite if exists
$params['tags'][] = 'cool'; // Allows multiple values
// Note that this will url_encode all values
$url_parts['query'] = http_build_query($params);
// If you have pecl_http
echo http_build_url($url_parts);
// If not
echo $url_parts['scheme'] . '://' . $url_parts['host'] . $url_parts['path'] . '?' . $url_parts['query'];
You should put this in a function at least, if not a class.
Here's a shorter version of the accepted answer:
$url .= (parse_url($url, PHP_URL_QUERY) ? '&' : '?') . 'category=action';
Edit: as discussed in the accepted answer, this is flawed in that it doesn't check to see if category already exists. A better solution would be to treat the $_GET for what it is - an array - and use functions like in_array().
$data = array('foo'=>'bar',
'baz'=>'boom',
'cow'=>'milk',
'php'=>'hypertext processor');
$queryString = http_build_query($data);
//$queryString = foo=bar&baz=boom&cow=milk&php=hypertext+processor
echo 'http://domain.com?'.$queryString;
//output: http://domain.com?foo=bar&baz=boom&cow=milk&php=hypertext+processor
This function overwrites an existing argument
function addToURL( $key, $value, $url) {
$info = parse_url( $url );
parse_str( $info['query'], $query );
return $info['scheme'] . '://' . $info['host'] . $info['path'] . '?' . http_build_query( $query ? array_merge( $query, array($key => $value ) ) : array( $key => $value ) );
}
Example with updating existent parameters.
Also url_encode used, and possibility to don't specify parameter value
<?
/**
* Add parameter to URL
* #param string $url
* #param string $key
* #param string $value
* #return string result URL
*/
function addToUrl($url, $key, $value = null) {
$query = parse_url($url, PHP_URL_QUERY);
if ($query) {
parse_str($query, $queryParams);
$queryParams[$key] = $value;
$url = str_replace("?$query", '?' . http_build_query($queryParams), $url);
} else {
$url .= '?' . urlencode($key) . '=' . urlencode($value);
}
return $url;
}
Use strpos to detect a ?. Since ? can only appear in the URL at the beginning of a query string, you know if its there get params already exist and you need to add params using &
function addGetParamToUrl(&$url, $varName, $value)
{
// is there already an ?
if (strpos($url, "?"))
{
$url .= "&" . $varName . "=" . $value;
}
else
{
$url .= "?" . $varName . "=" . $value;
}
}
<?php
$url1 = '/test?a=4&b=3';
$url2 = 'www.baidu.com/test?a=4&b=3&try_count=1';
$url3 = 'http://www.baidu.com/test?a=4&b=3&try_count=2';
$url4 = '/test';
function add_or_update_params($url,$key,$value){
$a = parse_url($url);
$query = $a['query'] ? $a['query'] : '';
parse_str($query,$params);
$params[$key] = $value;
$query = http_build_query($params);
$result = '';
if($a['scheme']){
$result .= $a['scheme'] . ':';
}
if($a['host']){
$result .= '//' . $a['host'];
}
if($a['path']){
$result .= $a['path'];
}
if($query){
$result .= '?' . $query;
}
return $result;
}
echo add_or_update_params($url1,'try_count',1);
echo "\n";
echo add_or_update_params($url2,'try_count',2);
echo "\n";
echo add_or_update_params($url3,'try_count',3);

echo add_or_update_params($url4,'try_count',4);

$parameters = array();
foreach ($get as $key => $value)
{

One-liner:
$url .= (strpos($url, '?') ? '&' : '?') . http_build_query($additionalParams);
using http_build_query is recommended because it encodes special characters (for example spaces or # in email addresses)
Improved version for 2022
This allows existing parameters to be replaced, and also preserves existing URL fragment (the part after # at the end of an URL)
function addParametersToUrl(string $url, array $newParams): string
{
$url = parse_url($url);
parse_str($url['query'] ?? '', $existingParams);
$newQuery = array_merge($existingParams, $newParams);
$newUrl = $url['scheme'] . '://' . $url['host'] . ($url['path'] ?? '');
if ($newQuery) {
$newUrl .= '?' . http_build_query($newQuery);
}
if (isset($url['fragment'])) {
$newUrl .= '#' . $url['fragment'];
}
return $newUrl;
}
Testing:
$newParams = [
'newKey' => 'newValue',
'existingKey' => 'new',
];
echo addParametersToUrl('https://www.example.com', $newParams);
// https://www.example.com?newKey=newValue&existingKey=new
echo addParametersToUrl('https://www.example.com/', $newParams);
// https://www.example.com/dir/?newKey=newValue&existingKey=new
echo addParametersToUrl('https://www.example.com/dir/', $newParams);
// https://www.example.com/dir/?newKey=newValue&existingKey=new
echo addParametersToUrl('https://www.example.com/dir/file?foo=bar', $newParams);
// https://www.example.com/dir/file?foo=bar&newKey=newValue&existingKey=new
echo addParametersToUrl('https://www.example.com/dir/file?foo=bar&existingKey=old', $newParams);
// https://www.example.com/dir/file?foo=bar&existingKey=new&newKey=newValue
echo addParametersToUrl('https://www.example.com/dir/file?foo=bar&existingKey=old#hash', $newParams);
// https://www.example.com/dir/file?foo=bar&existingKey=new&newKey=newValue#hash
echo addParametersToUrl('https://www.example.com/dir/file#hash', $newParams);
// https://www.example.com/dir/file?newKey=newValue&existingKey=new#hash
echo addParametersToUrl('https://www.example.com/dir/file?foo=bar#hash', $newParams);
// https://www.example.com/dir/file?foo=bar&newKey=newValue&existingKey=new#hash
I think you should do it something like this.
class myURL {
protected $baseURL, $requestParameters;
public function __construct ($newURL) {
$this->baseurl = $newURL;
$this->requestParameters = array();
}
public function addParameter ($parameter) {
$this->requestParameters[] = $parameter;
}
public function __toString () {
return $this->baseurl.
( count($this->requestParameters) ?
'?'.implode('&', $this->requestParameters) :
''
);
}
}
$url1 = new myURL ('http://www.acme.com');
$url2 = new myURL ('http://www.acme.com');
$url2->addParameter('sort=popular');
$url2->addParameter('category=action');
$url1->addParameter('category=action');
echo $url1."\n".$url2;
After searching for many resources/answers on this topic, I decided to code my own. Based on #TaylorOtwell's answer here, this is how I process incoming $_GET request and modify/manipulate each element.
Assuming the url is: http://domain.com/category/page.php?a=b&x=y
And I want only one parameter for sorting: either ?desc=column_name or ?asc=column_name. This way, single url parameter is enough to sort and order simultaneously. So the URL will be http://domain.com/category/page.php?a=b&x=y&desc=column_name on first click of the associated table header row.
Then I have table row headings that I want to sort DESC on my first click, and ASC on the second click of the same heading. (Each first click should "ORDER BY column DESC" first) And if there is no sorting, it will sort by "date then id" by default.
You may improve it further, like you may add cleaning/filtering functions to each $_GET component but the below structure lays the foundation.
foreach ($_GET AS $KEY => $VALUE){
if ($KEY == 'desc'){
$SORT = $VALUE;
$ORDER = "ORDER BY $VALUE DESC";
$URL_ORDER = $URL_ORDER . "&asc=$VALUE";
} elseif ($KEY == 'asc'){
$SORT = $VALUE;
$ORDER = "ORDER BY $VALUE ASC";
$URL_ORDER = $URL_ORDER . "&desc=$VALUE";
} else {
$URL_ORDER .= "&$KEY=$VALUE";
$URL .= "&$KEY=$VALUE";
}
}
if (!$ORDER){$ORDER = 'ORDER BY date DESC, id DESC';}
if ($URL_ORDER){$URL_ORDER = $_SERVER[SCRIPT_URL] . '?' . trim($URL_ORDER, '&');}
if ($URL){$URL = $_SERVER[SCRIPT_URL] . '?' . trim($URL, '&');}
(You may use $_SERVER[SCRIPT_URI] for full URL beginning with http://domain.com)
Then I use resulting $ORDER I get above, in the MySQL query:
"SELECT * FROM table WHERE limiter = 'any' $ORDER";
Now the function to look at the URL if there is a previous sorting and add sorting (and ordering) parameter to URL with "?" or "&" according to the sequence:
function sort_order ($_SORT){
global $SORT, $URL_ORDER, $URL;
if ($SORT == $_SORT){
return $URL_ORDER;
} else {
if (strpos($URL, '?') !== false){
return "$URL&desc=$_SORT";
} else {
return "$URL?desc=$_SORT";
}
}
}
Finally, the table row header to use the function:
echo "<th><a href='".sort_order('id')."'>ID</a></th>";
Summary: this will read the URL, modify each of the $_GET components and make the final URL with parameters of your choice with the correct form of usage of "?" and "&"
public function addGetParamToUrl($url, $params)
{
foreach ($params as $param) {
if (strpos($url, "?"))
{
$url .= "&" .http_build_query($param);
}
else
{
$url .= "?" .http_build_query($param);
}
}
return $url;
}
another improved function version. Mix of existing answers with small improvements (port support) and bugfixes (checking keys properly).
/**
* #param string $url original url to modify - can be relative, partial etc
* #param array $paramsOverride associative array, can be empty
* #return string modified url
*/
protected function overrideUrlQueryParams($url, $paramsOverride){
if (!is_array($paramsOverride)){
return $url;
}
$url_parts = parse_url($url);
if (isset($url_parts['query'])) {
parse_str($url_parts['query'], $params);
} else {
$params = [];
}
$params = array_merge($params, $paramsOverride);
$res = '';
if(isset($url_parts['scheme'])) {
$res .= $url_parts['scheme'] . ':';
}
if(isset($url_parts['host'])) {
$res .= '//' . $url_parts['host'];
}
if(isset($url_parts['port'])) {
$res .= ':' . $url_parts['port'];
}
if (isset($url_parts['path'])) {
$res .= $url_parts['path'];
}
if (count($params) > 0) {
$res .= '?' . http_build_query($params);
}
return $res;
}
Try this function to add URL parameters.
Then you can disable the link when parameter is set so there is no url parameter duplicate.
<?php
function addQueryString($a)
{
if (empty($_SERVER['QUERY_STRING']))
return '?' . $a;
else if (!empty($_SERVER['QUERY_STRING']))
return '?' . $_SERVER['QUERY_STRING'] . '&' . $a;
}
?>

In case you are using WordPress you can simply use
add_query_args(['sort' => 'asc'], 'http:/example.com/?search=news')

Suddenly the code to get Twitter login URL stopped working.
Error returned by generated URL to get outh_token is:
<error code="32">Could not authenticate you.</error>
URL generated to get outh_token is:
https://api.twitter.com/oauth/request_token?oauth_callback=http://project.local.com/dashboard/redirect-from-twitter&oauth_consumer_key=if5hivS82GJURRJMp60CjXQVd&oauth_nonce=1426244533&oauth_signature=Ag16Q1uwiiAJsLu5Zbl3oy1hil4%3D&oauth_signature_method=HMAC-SHA1&oauth_timestamp=1426244533&oauth_version=1.0
It seems as if something is wrong with signature.
Following is my code to generate signature:
public function buildsignature($method, $params, $url, $access_token_secret = null)
{
$keys = $this->_urlencode_rfc3986(array_keys($params));
$values = $this->_urlencode_rfc3986(array_values($params));
$params = array_combine($keys, $values);
uksort($params, 'strcmp');
// convert params to string
foreach ($params as $k => $v) {
$pairs[] = $this->_urlencode_rfc3986($k) . '=' . $this->_urlencode_rfc3986($v);
}
$concatenatedParams = implode('&', $pairs);
// form base string (first key)
$baseString = $method . "&" . $this->_urlencode_rfc3986($url) . "&" . $this->_urlencode_rfc3986($concatenatedParams);
// form secret (second key)
if ($access_token_secret) {
$key_parts = array(
self::CLIENT_SECRET,
$access_token_secret
);
$key_parts = $this->_urlencode_rfc3986($key_parts);
$secret = implode('&', $key_parts);
//$secret = rawurlencode(self::CLIENT_SECRET) . '&' . rawurlencode($access_token_secret);
} else {
$secret = $this->_urlencode_rfc3986(self::CLIENT_SECRET)."&";
}
return base64_encode(hash_hmac('sha1', $baseString, $secret, TRUE));
}
I tried answers from:
http://stackoverflow.com/questions/9861756/signin-with-twitter-stopped-working-suddenly
But I'm testing it on my local system, so I hope that there isn't due to any time gap. It's not creating the URL to be used for login purpose.
I modified my code and replaced:
$pairs[] = $this->_urlencode_rfc3986($k) . '=' . $this->_urlencode_rfc3986($v);
with
$pairs[] = $k . '=' . $v;
where $this->_urlencode_rfc3986() is
public function _urlencode_rfc3986($input)
{
if (is_array($input)) {
return array_map($this->_urlencode_rfc3986, $input);
}
else if (is_scalar($input)) {
return str_replace('+',' ',str_replace('%7E', '~', rawurlencode($input)));
}
else{
return '';
}
}
Now that's crazy because that previous code was working from last few months, it stopped suddenly. But the question is how could someone find such issues.
I found a bit of code for stripping a query string and adding a new value to it, but I want to be able to do this with an array of options. Could someone give me a hand in modifying this code to do that?
Current code:
function add_querystring_var($url, $key, $value) {
$url = preg_replace('/(.*)(\?|&)' . $key . '=[^&]+?(&)(.*)/i', '$1$2$4', $url . '&');
$url = substr($url, 0, -1);
$value = $value ? "=".urlencode($value) : '';
if (strpos($url, '?') === false)
return ($url . '?' . $key . $value);
else
return ($url . '&' . $key . $value);
}
And I want it to do a foreach for each key and value given and then rebuild the new url.
Example: add_querystring_var(curPageURL(), array("order","sort"), array("swn","DESC"))
So I want the following URL http://www.example.com/students when put through the example above would return http://www.example.com/students?order=swn&sort=DESC
Does anyone know how I can do this? I'm new to this area of PHP. :)
UPDATE:
I forgot to mention sometimes the url may have other queries in it, so I want it to replace the ones that I enter into my array.
Example 1: http://www.example.com/students?page=2 would need to turn into http://www.example.com/students?page=2&order=swn&sort=DESC
Example 2: http://www.example.com/students?page=2&order=name&sort=ASC would need to turn into http://www.example.com/students?page=2&order=swn&sort=DESC
function add_querystring_var($url, $additions) {
$parsed = parse_url($url);
if (isset($parsed['query'])) {
parse_str($parsed['query'], $query);
} else {
$query = array();
}
$parsed['query'] = http_build_query(array_merge($query, $additions));
return http_build_url($parsed);
}
Use it this way:
$new_url = add_querystring_var($url, array('order' => 'swn', 'sort' => 'DESC'));
If you're getting errors saying that http_build_url is not defined, see
PHP http_build_url() and PECL Install
You're kind of reinventing the wheel with that function... first off, you'd be better off using urlencode() on your key/value data rather than that regular expression (and I see that you're not encoding your value string at all)
As dpDesignz mentions in his comment - there is a built-in function available: http_build_query()
$querydata = array('foo' => array('bar', 'baz'),
'baz'=>'boom',
'cow'=>'milk',
'php'=>'hypertext processor');
$querystring = http_build_query($data, '', '&');
Or, to use your example:
$querydata = array("order" => "swn", "sort" => "DESC");
$url = curPageURL();
$concat = "?";
if (strpos($url, "?") !== false)) {
$concat = "&"
}
$url .= $concat . http_build_query($data, '', '&');
I want to read one parameter from a specific URl :
Like : http://www.youtube.com/watch?v=MrOiL74P-9E&feature=watch
Output should be : MrOiL74P-9E
I try to search and I found this function :
function remove_query_part($url, $term)
{
$query_str = parse_url($url, PHP_URL_QUERY);
if ($frag = parse_url($url, PHP_URL_FRAGMENT)) {
$frag = '#' . $frag;
}
parse_str($query_str, $query_arr);
unset($query_arr[$term]);
$new = '?' . http_build_query($query_arr) . $frag;
return str_replace(strstr($url, '?'), $new, $url);
}
This function just remove one parameter and return the rest. Can anyone edit this function to return just the video ID and Ignore whatever else in the URL.
$query_str = parse_url($url, PHP_URL_QUERY);
parse_str($query_str, $args);
print $args['v']; // <- MrOiL74P-9E
I think you know how to put this into a function...
Quick and dirty:
$url='http://www.youtube.com/watch?v=MrOiL74P-9E&feature=watch';
function test($url)
{
$data=parse_url($url);
if(!isset($data['query']))
{
return null;
}
else
{
$ex=explode('&', $data['query']);
foreach($ex as $key => $val)
{
$param=explode('=', $val);
if($param[0]=='v')
{
return $param[1];
break;
}
}
}
}
echo test($url);
Not tested but you could try....
function remove_query_part($url, $term) {
// get the query part of the string (i.e. after the '?')
$query_str = parse_url($url, PHP_URL_QUERY);
$queryItems = explode('&', $query_str);
$item = array();
$itemArray = array();
foreach ($queryItems as $item) {
$itemArray = explode('=', $item);
if($item[0] == $term) {
return $item[1];
}
}
return false;
}
Want to remove p2variable from url string, below are 3 cases if case 3 also remove ? sign.

Want to achieve result with single preg_replace expression.
Don't use regular expressions when dealing with URL values. It's much easier (and safer) to handle them as a URL instead of plain text.
This could be one way to do it:
Split the url first and parse the query string
Take the parameter out
Rebuild the url
The below code is an example of such an algorithm:
// remove $qs_key from query string of $url
// return modified url value
function clean_url_qs($url, $qs_key)
{
// first split the url in two parts (at most)
$parts = explode('?', $url, 2);
// check whether query string is passed
if (isset($parts[1])) {
// parse the query string into $params
parse_str($parts[1], $params);
// unset if $params contains $qs_key
if (array_key_exists($qs_key, $params)) {
// remove key
unset($params[$qs_key]);
// rebuild the url
return $parts[0] .
(count($params) ? '?' . http_build_query($params) : '');
}
}
// no change required
return $url;
}
Test code:
echo clean_url('http://www.domain.com/myscript.php?p1=xyz&p2=10&p3=ghj', 'p2'), "\n";
echo clean_url('http://www.domain.com/myscript.php?p2=10&p3=ghj', 'p2'), "\n";
echo clean_url('http://www.domain.com/myscript.php?p2=10', 'p2'), "\n";
Found this in one of my old projects (a bit of shitcode, but...), may help you:
$unwanted_param = 'p2';
$s = 'http://www.domain.com/myscript.php?p1=xyz&p2=10&p3=ghj';
$s = parse_url($s);
$params = explode('&', $s['query']);
$out_params = array();
foreach ($params as $key => &$param) {
list($name, $value) = explode('=', $param);
if ($unwanted_param == $name) {
unset($params[$key]);
} else {
$out_params[$name] = $value;
}
}
$query = '?' . http_build_query($out_params);
$result = $s['scheme'] . '://' . $s['host'] . $s['path'] . $query;
var_dump($result);
Using preg_replace, something like
$url = preg_replace('!([\?&]p2=[^&\?$]+)!i', '', $url);
However, personally I'd do the following
if (strpos($url, '?') !== false) {
list($domain, $qstring) = explode('?', $url, 2);
parse_str($qstring, $params);
if (isset($params['p2'])) {
unset($params['p2']);
}
$qstring = !empty($params) ? '?' . http_build_query($params) : '';
$url = $domain . $qstring;
}
I've a small problem with my internationalization:
I want to have some url looking like this: http://mywebsite/eng/controller/action/params...
I found this http://nuts-and-bolts-of-cakephp.com/2008/11/28/cakephp-url-based-language-switching-for-i18n-and-l10n-internationalization-and-localization/
This is working nice most of time. But I've one case where this hasn't the expected result.
When I'm using $this->Html->link with named parameters, I don't get my nice structure, but something like http://mywebsite/controller/action/paramX:aaa/paramxY:bbb/language:eng
I think this is a routing problem, but I can't figure what is going wrong?
Thank you very much
This is because cakephp doens't find a route in routes.php that corresponds to this link. In other words, you'll have to define this route in the routes.php file
Router::connect('/:language/:controller/:action/:paramX/:paramY');
Once this set, $this->Html->link will output a nice url
I finally did this:
I created a custom CakeRoute, in this cakeRoute, I override the "match" url and the _writeUrl method.
Now every thing is working like a charm :)
For those which are interessted by the route class:
<?php
class I18nRoute extends CakeRoute {
/**

* Add a regex condition on the lang param to be sure it matches the available langs
*
* #param string $template Template string with parameter placeholders

* #return void
* #access public

public function __construct($template, $defaults = array(), $options = array()) {
//$defaults['language'] = Configure::read('Config.language');
$options = array_merge((array)$options, array(
'language' => join('|', Configure::read('Config.languages'))
));
parent::__construct($template, $defaults, $options);
}
/**
