I want to get query string from a url and change it to the string format.
I copied the following code from other related posts on stackoverflow, but it is not working properly for me.
<?php
$url="www.example.com/user.php?uname=alan&password=2222";
$parse=parse_str($url);
echo $uname;
echo $password;
This code returns the second variable $password as expected, but it failed for the first variable $uname
undefined variable: uname
Is there something missing in the code?
Any help is greatly appriciated!
Thanks.
It looks like parse_str does not work quite correctly with your URL. You probably want to use it in conjunction with parse_url
eg:
$url="www.example.com/user.php?uname=alan&password=2222";
$str = parse_url($url, PHP_URL_QUERY);
$parse = parse_str($str);
echo $uname;
echo $password;

I am trying to parse url and extract value from it .My url value is www.mysite.com/register/?referredby=admin. I want to get value admin from this url. For this, I have written following code. Its giving me value referredby=admin, but I want only admin as value. How Can I achieve this? Below is my code:
<?php
$url = $current_url="//".$_SERVER['HTTP_HOST'].$_SERVER['REQUEST_URI'];
setcookie('ref_by', parse_url($url, PHP_URL_QUERY));
echo $_COOKIE['ref_by'];
?>
You can use parse_str() function.
$url = "www.mysite.com/register/?email=admin";
$parts = parse_url($url);
parse_str($parts['query'], $query);
echo $query['email'];
Try this code,
$url = "www.mysite.com/register/?referredby=admin";
$parse = parse_url($url, PHP_URL_QUERY);
parse_str($parse, $output);
echo $output['referredby'];
$referred = $_GET['referredby'];
$referred = "referredby=admin";
$pieces = explode("=", $referred);
echo $pieces[1]; // admin
I don't know if it's still relevant for you, but maybe it is for others: I've recently released a composer package for parsing urls (https://www.crwlr.software/packages/url). Using that library you can do it like this:
$url = 'https://www.example.com/register/?referredby=admin';
$query = Crwlr\Url\Url::parse($url)->queryArray();
echo $query['referredby'];
The parse method parses the url and returns an object, the queryArray method returns the url query as array.
Is not a really clean solution, but you can try something like:
$url = "MYURL";
$parse = parse_url($url);
parse_str($parse['query']);
echo $referredby; // same name of the get param (see parse_str doc)
PHP.net: Warning
Using this function without the result parameter is highly DISCOURAGED and DEPRECATED as of PHP 7.2.
Dynamically setting variables in function's scope suffers from exactly same problems as register_globals.
Read section on security of Using Register Globals explaining why it is dangerous.
I need one help. I need to fetch all data from query string using PHP but some special charcters like (i.e-+,- etc) are not coming. I am explaining my code below.
http://localhost/test/getmethod.php?name=Goro + Gun
Here I need to get the value assign to name using the below code.
<?php
$name=$_GET['name'];
echo $name;
?>
Here I am getting the output like Goro Gun but I need the original value i.e-Goro + Gun .Please help me to resolve this issue.
#subhra try this for this case name=Goro + Gun:
<?php
$nameArr = explode('=', $_SERVER['QUERY_STRING']);
$name = str_replace("%20", " ", $nameArr[1]);
echo $name;
?>
$_SERVER['QUERY_STRING'] - this will return you full query string
Iam new to xpath. I got a url using curl and domdocument but the problem is that the link is formated in this way: /bookstore/book.php
So then I wanna echo it to my own href link, it doesnot work ofcourse. The awnser would be to make a variable thats contains both the www.hello.com and the link I got from domdocument.
Here is my line of code:
$link = $linkquery->item(2)->nodeValue;
But if I do this it just gives me an 0
$url = "http://www.hello.com" + $link;
Any ideas? I guess I have missed something basic.
Regards
EDIT
Thanks for the help, the awnser was $url = "http://www.hello.com$link";
Isn't the string concatenation operator in PHP the dot operator .? So you want $url = "http://www.hello.com" . $link; or simply $url = "http://www.hello.com$link";.
I am getting content of XML using this code:
$xml = simplexml_load_file("X.xml");
echo $xml->CountryList->Country[1];
Here is the X.xml:
<PickUpCityListRQ>
<CountryList>
<Country>Albania</Country>
<Country>Andorra</Country>
</CountryList>
</PickUpCityListRQ>
Everything works fine, it returns Andorra for me, but, when I try to use url with special characters, like this one:
http://somelink/ServiceRequest.do?xml=<PickUpCityListRQ><Credentials username='USERNAME' password='PASSWORD' remoteIp='IP'/><Country>UK</Country></PickUpCityListRQ>
This link won't work for you as it just an example, but believe, real link returns the same content as X.xml. I know that the reason of that are special characters in the link, but I can't get it work. I tried something like this:
$username = "USERNAME";
$password = "PASSWORD";
$accessurl = htmlspecialchars("Credentials username='$username' password='$password' remoteIp='123.123.123.123'/");
$required = htmlspecialchars("<PickUpCityListRQ><$accessurl><Country>UK</Country></PickUpCityListRQ>");
$url = 'somelink/service/ServiceRequest.do?xml='.$required;
echo $url;
It returns (with echo) the required link, in case if I use it manualy (in browser) I'll get to the required content. But if I try to get XML content using this code:
$xml = simplexml_load_file($url);
echo $xml->CountryList->Country[1];
I won't work.
Any ideas?
Thank you in advance.
htmlspecialchars is used to protect special char inside an HTML content page (especially on user input, to avoid some sort of XSS or other attack..).
When you are manipulating URLs, you should use instead urlencode to send your content as parameter of the URL.
So your URL will be:
http://someserver/somethink/services/ServiceRequest.do?xml=%3CPickUpCityListRQ%3E%3CCredentials%20username%3D'USERNAME'%20password%3D'PASSWORD'%20remoteIp%3D'IP'%2F%3E%3CCountry%3EUK%3C%2FCountry%3E%3C%2FPickUpCityListRQ%3E
As the documentation says, urldecode is not requiered because the superglobals $_GET and $_REQUEST are already urldecoded. So, in your script which do the job you can directly use the value in your $_GET entry.
$xml = simplexml_load_string($_GET['xml']);
documentation : urlencode
Answer stolen from PHP simplexml_load_file with special chars in URL
Use this
$username = "USERNAME";
$password = "PASSWORD";
$accessurl = "Credentials username='$username' password='$password' remoteIp='123.123.123.123'/";
$required = "<PickUpCityListRQ><$accessurl><Country>UK</Country></PickUpCityListRQ>";
$url= rawurlencode("somelink/service/ServiceRequest.do?xml={$required}");
$xml = simplexml_load_file($url);
echo $xml->CountryList->Country[1];
I'm attempting to run the script referenced here
<?php
$url = 'index.php?option=com_content&view=article&catid=334:golfeq&id=2773:xcelsiors&Itemid=44';
parse_str(parse_url($url, PHP_URL_QUERY), $vars);
echo "Variables:\n";
print_r($vars);
$id = reset(explode(':', $vars['id']));
echo "The id is $id\n";
$id = intval($vars['id']);
echo "Again, the id is $id\n";
Unlike the example shown - which works - on my station, the variable array shows that "&" is encoded to "amp;" causing that script not to work for me.
When I output the variable array from the example, I get variables like [amp;id]
How can that scriptbe modified with the "&" decoded so it will work on my station?
Thanks for your help
simple solution is
$url = html_entity_decode('index.php?option=com_content&view=article&catid=334:golfeq&id=2773:xcelsiors&Itemid=44');
