Using window.location.hash (used to pass in ID for page) returns something like the following:
Also, for people asking why I used window.location.hash instead of window.location.href is because window.location.href started looping infinitely for some reason, and .hash does not. I don't think this should be a big deal, but let me know if it is and if I need to change it.

[The string of numbers is actually epoch system time]
When using PHP to try to retrieve this variable It is not picking up any text in the file It's supposed to write to.
<?php
$myfile = fopen("File1.txt","w");
echo $_GET['name'];
fwrite($myfile, $_GET['name']);
fclose($myfile);
?>
Try to print $_SERVER variable and it will give you the array and in the desired key you can get the values. It can help you to find that variable in the string.
If you want to get the value after the hash mark or anchor, that isn't possible with "standard" HTTP as this value is never sent to the server. However, you could parse a URL into bits, including the fragment part, using parse_url().
This should do the trick:
<?php
$name_query = parse_url("http://website.com/NewPage.php#?name=1418019307305");
$get_name = substr($name_query['query'], strpos($name_query['query'], "=") + 1);
echo $get_name;
?>
Working example: http://codepad.org/8sHYUuCS
Then you can use $get_name to store "name" value in a text file.
The hash tag is a fragment that never gets processed by the server, but rather the user-agent, i.e. the browser, so JavaScript may certainly access it. (See https://www.rfc-editor.org/rfc/rfc3986#section-3.5). PHP does allow you to manipulate a url that contains a hash tag with parse_url(). Here's another way to get the info:
<?php
$parts = parse_url("http://website.com/NewPage.php#?name=1418019307305");
list(,$value) = explode("=",$parts['fragment']);
echo $value; // 1418019307305
The placement of the hash tag in this case wipes out the query string so $_SERVER['QUERY_STRING'] will display an empty string. If one were to rewrite the url following best practice, the query string would precede the hash tag and any info following that mark. In which case the script for parsing such a url could be a variation of the preceding, as follows:
<?php
$bestPracticeURL = "http://website.com/NewPage.php?name=1418019307305#more_data";
$parts = parse_url( $bestPracticeURL );
list(,$value) = explode("=", $parts['query']);
$hashData = $parts['fragment'];
echo "Value: $value, plus extra: $hashData";
// Value: 1418019307305, plus extra: more_data
Note how in this case parse_url was able to capture the query string as well as the hash tag data. Of course, if the query string had more than one key and value, then you might need to explode on the '&' into an array and then explode each array element to extract the value.

I need to parse user submitted urls before echoing their submitted urls on my page. need to parse the urls as I won't know what urls they will be submitting nor the structures of their urls.
On each submitted url, I need to add the key part of each query string on the $key array and the value part of each query string on the $value array. How to do this ?
Example, a user submits this url:
http://example.com/autos/cars/list.php?country=usa&min_price=5000
FIRST STEP
In this example, I need the $key array to be populated with:
country,
min_price
And, I need the $value array to be populated with:
usa,
5000
Then I need to echo each array's values.
How to do this ?
SECOND STEP
I need to auto add the appropriate encoding functions in the submitted url. So now I won't be echoing like this:
echo 'http://example.com/autos/cars/list.php?country=usa&min_price=5000';
But after parsing the url and after adding the appropriate encoding php functions in the correct spots of the url, I will be echoing like this:
echo rawurlencode('http://example.com/autos/cars/list.php') .'?country=' .urlencode('usa') .'&min_price=' .intval(5000);
Can you see, I auto added rawurlencode on the file path and urlencode on the query string's values and can you see I added intval where the query string's value was an INT ?
Well, I did all this additions manually here ofcourse to show you what I want php to do on auto. I really need to get php to auto analyze the url and auto add the rawurlencode(), urlencode() and intval() where appropriate. Add the 3 functions on the correct spots on the url.
How to do this ?
Once these two steps are achieved, then I can say a custom php function has been built that analyzes submitted urls and auto encodes the urls with the appropriate encoding functions (rawurlencode, urlencode, intval) on the correct spots on the url.
My Failed Attempt:
print_r(parse_url($url)); echo '<br>';
$keys = array(print_r(parse_url($url))); echo '<br>';
foreach($keys as $key=>$value)
{
$key = array();
$value = array();
echo $key['0']; echo '<br>';
echo $value['0']; echo '<br>';
}
Don't know how to proceed from this point onwards.
So im trying to get an url from the address bar that looks like this:
http://mysite.com/url.php?name=http://test.com/format.jsp?id=738ths3&secure=false
I'm using the $_GET variable to read it right off the URL my code is as follows
$arc = rawurlencode($_GET['name']);
echo "URL: $arc";
This only returns
URL: http://imgur.com/format.jsp?id=738ths3
It 's missing the &secure=false
What i want it to look:
URL: http://test.com/format.jsp?id=738ths3&secure=false
I have tried urlencode, rawurlencode with no avail, i have looked in google a number of forums and stackoverflow none of the answer help, any ideas? Thanks!
urlencode shows this:
URL: http%3A%2F%2Ftest.com
so i cant have that either!
You'll need to urlencode() before constructing the URL, ie:
$url = "http://mysite.com/url.php?name=".urlencode('http://test.com/format.jsp?id=738ths3&secure=false');
This way, you will be able obtain the full URL as a name GET parameter from $_GET['name'].
Explanation:
Without urlencode() it when constructing the URL, PHP would treat is as 2 separate parameters, separated by &:
$_GET['name']
which is http://imgur.com/format.jsp?id=738ths3 for your case
$_GET['secure']
which is false for your case
Alternatively:
From your comment, it seems that you do not have control for the URL construction. You can get the full $_GET in a single string using http_build_query:
$name = http_build_query($_GET);
You would then obtain:
echo $name; // name=http://test.com/format.jsp?id=738ths3&secure=false
// which you would then may want to strip away the first 'name='
$name = substr($name, strlen('name='));
echo $name; // to obtain http://test.com/format.jsp?id=738ths3&secure=false
The original URL, http://mysite.com/url.php?name=http://test.com/format.jsp?id=738ths3&secure=false, contains two query-string parameters: name and secure. The & in the query-string belongs to the full URL, not the URL in the name parameter.
If you have control over this value, when declaring the link/URL, use PHP's urlencode() to encode the full name value, such as:
$url = "http://mysite.com/url.php?name=" . urlencode("=http://test.com/format.jsp?id=738ths3&secure=false");
This will properly encode the name parameter and your $arc = $_GET['name']; will work as desired.
If you do not have control over setting the value and are simply parsing something you're receiving, you can split the given string on the name= parameter and assume everything else after it is part of name:
$splitQuery = split('name=', $_SERVER['REQUEST_URI']);
$arc = $splitQuery[1];
To decode the encoded URL, after you've accessed it, use PHP's urldecode():
$arc = urldecode($_GET['name']); // assuming you're properly encoding the `name` parameter
If you cannot encode the URL, you can get the current URI with this code:
$url = $_SERVER["REQUEST_URI"];
that in your case, the $url is :
/url.php?name=http://test.com/format.jsp?id=738ths3&secure=false
Then you can split it with explode and validate it and take the GET params from it.
In the below URL, I am trying to parse out the string everything that appears after "scid=" and "pid=" into 2 different variables. The two numbers associated with pid and scid don't have a fixed number of digits each time (they change). I'm approaching the problem in the following way: find location of "pid=" and parse out the string from after this location until the next "&". How do I do this?
http://oldnavy.gap.com/browse/product.do?cid=78425&vid=1&pid=113855&scid=113855012
parse_str(parse_url($url, PHP_URL_QUERY), $values);
echo $values['scid'];
echo $values['pid'];
See http://php.net/parse_str and http://php.net/parse_url.
If that URL was used to access the current page, then see the earlier comment about $_GET.
<?php
$pid=$_GET['pid'];
$scid=$_GET['scid'];
?>
If you otherwise access that as a string, here's a bit of code I have used to pull out pieces of text before:
<?php
//assumes that the URL is the value of $string.
list($temp,$pid)=split('pid=',$string);
list($pid,$temp)=split('&',$pid);
list($temp,$scid)=split('scid=',$string);
list($scid,$temp)=split('&',$scid); //allows for other name / value pairs to follow.
?>
I think I have the need to take a uri which has been decoded in PHP, and re-encode it.
Here is the situation:
JavaScript passes encoded uri as query string parameter to php script.
PHP script embeds uri as a hidden input value in an html document, responds with the document to a user agent.
JavaScript reads embedded uri and sets location of current document based on value of hidden input.
On Step 2, I am finding that the Uri is fully decoded after reading it in via $_GET. So when I embed the uri in the hidden input, it becomes un-encoded. So I would like to run a PHP script which re-encodes the Uri properly ex:
http://my.example.com/dog walk?is=very great
==>
http://my.example.com/dog%20walk?is=very%20great
Is there a pre-built php function for this or should I just write my own?
PLEASE NOTE: urlencode and urldecode are not the answer to get the desired input/output I have in the example above.
Thanks,
Macy
Are you looking for : http://fr.php.net/manual/en/function.urlencode.php ?
I don't know if will help you, but PHP have 3 useful functions:
$url = parse_url('put the url here');
parse_str( $url['query'], $query ); // generating an array by reference (yes, kinda weird)
echo $query; //in this line, you can encode or decode.
or, if you want to mount a query, you can use http_build_query(); that accepts values from an array, like:
$url = 'http://my.example.com/dog walk?';
$array = Array (
'is' => 'very_great',
);
$url_created = $url . http_build_query($array);
urldecode:

I'm sending a php script multiple urls (about 15) at once, all containing about 5 url variables. In my script, I'm parsing the chunk of urls into individual ones by splitting them with two backslashes (which i add upon before to the script), and then curling each individual url. However, when I run my script, it only accepts a url up to the "&" symbol. I'd like to have the entire chunk, so that I can split it up later in my script. What might be the best way to approach this issue?
Thanks.
An example of what happens when i send my script a url chunk:
<?php
/*
$url variable being sent to script:
http://www.test1.com?q1=a&q2=b&q3=c&q4=d\\http://www.test2.com?r1=a&r2=b&r3=c&r4=d\\http://www.test3.com?q1=a&q2=b&q3=c&q4=d\\http://www.test4.com?e1=a&e2=b&e3=c&e4=d
*/
$url = $_GET['url'];
echo $url; // returns http://www.test1.com?q1=a
//later on in my script, i just need to curl each "\\" seperated url
?>
You need to urlencode() the (data) URLs before appending them to your script's request.
Otherwise, PHP is going to to see ?listOfUrls=http://someurl.com/?someVar=SomeVal& and stop right there, due to the literal "&"
If you're building the query string in PHP you could try something like:
<?PHP
//imagine $urls is an array of urls
$qs = '?urls=';
foreach($urls as $u){
$q .= urlencode($u) .'\\';
}
I also suspect you can play with [] notation in the url so that on the other side of the GET, you get a nice clean array of URLs back, instead of having to parse on some delimiter like "\"
Since you didn't url encode your url param, everything after the first & is treated as the param to the original url.
The $_GET array is formed by splitting on ampersands. URL-encode the URLs before passing them as parameters. PHP should decode them for you.
Example: pass url=http://www.test1.com?q1=a%26q2=b%26q3=c%26q4=d\\http://www.test2.com?r1=a%26r2=b%26r3=c%26r4=d\\http://www.test3.com?q1=a%26q2=b%26q3=c%26q4=d\\http://www.test4.com?e1=a%26e2=b%26e3=c%26e4=d
You can do away with the '\\' by turning the parameter into an array. Example: use url[]=http://www.test1.com?q1=a%26q2=b%26q3=c%26q4=d&url[]=http://www.test2.com?r1=a%26r2=b%26r3=c%26r4=d&url[]=http://www.test3.com?q1=a%26q2=b%26q3=c%26q4=d&url[]=http://www.test4.com?e1=a%26e2=b%26e3=c%26e4=d
