My curl request string is created programmatically with a base URL from a database and an integer which is the page number. The string for the URL is correct. If I call the curl request with the base URL copied in to the function, it works. If I call it with the programmatically created string (which is identical) the wrong page is called - it appears to be missing one of the parameters from the string (affiliation):
This has been running for years with no issue. The server is PHP 5.6. The string in the database is stored as varchar(500). I have tried TEXT as the type in the database. I have tried various ways of forcing a string in the function. The first $testurl below is copied and pasted from the second $testurl if I get the code to echo it before making the curl call.
//choose one of the $testurls to try
$testurl = 'https://log.concept2.com/challenges/holiday/2019/honorboard/200?country=0&state=&affiliation=1397&sort=distance&page=2';
//In this... $url comes from the database, $gotopage comes from a loop
$testurl = (string)($url . $gotopage);
$c = curl_init($testurl)
$str = curl_exec($c);
curl_close($c);
echo $str;
die;
The first $testurl returns what I want, a list of people in the same team.
The second $testurl returns a list of people belonging to any affiliation.
Edit
var_dump($testurl) gives:
string(134) "https://log.concept2.com/challenges/holiday/2019/honorboard/200?country=0&state=&affiliation=1397&sort=distance&page=2"
The full code is more of a challenge. The $GoToPage is an integer. $url is pulled from a database. The pertinent line is:
$url = $challenge['mb2_Challenges']['challenge_url'];
Where the $challenge is created from a mysqli SELECT... FROM... WHEN... query with SQL. mb2_Challenges is the table, challenge_url is the table.
For those who are as foolish as me, here is the answer:
The string from the script was urlencoded, so & instead of &. I was in too much of a rush to spot this. It just needed htmlspecialchars_decode.
Lesson learned: always look at the source!

I have a PHP script which I can query with a variable.
Here is the URL to do that:
ajax.php?var=3
And here is the bit (inside the PHP file) that grabs that number - it's a phpBB method that works similarly to GET()/POST():
$alink = $request->variable('var', 1);
echo $alink;
Here's the API section about this 'request' method if interested.
And this is what is outputted on the page when visited:
3
So that works fine. However, when I used a string instead of a number, all it returns is 0 :(
ajax.php?var=Apple
Returns:
0
When visited... so like, why is this and what do I have to do to get my request method to recognised the string? It works fine with a number, so why not a string too?
Thanks :)
I want to get the last part of an url that looks like this:
http://localhost:8888/blog/public/index.php/categories/Horror
I've tried it with
$endOfUrl = end(explode('/',$url));
but the thing is I get a notice that "Only variables should be passed by reference"
I need this "Horror" to get it's ID in my database and get all the posts with this id, since I'm trying to code a blog to get experience with php.
Another question linked to this: Is it possible to make it dynamic so it can be used for all the other categories as well? Or do I have to do this for every single category?
I'm new to the world of php so I would really appreciate it if someone could help me on this.
Try like this way for end() but If I were you I will try basename() to get my job done.
<?php
$url = 'http://localhost:8888/blog/public/index.php/categories/Horror';
$exploded = explode('/',$url);
$endOfUrl = end($exploded);
echo $endOfUrl;
?>
Reason why it is not working on single line:
end() requires a reference, because it modifies the internal
representation of the array (i.e. it makes the current element pointer
point to the last element).The result of explode('.', $url) cannot be
turned into a reference and this is a restriction in the PHP language itself.

Using basename(),
$url = 'http://localhost:8888/blog/public/index.php/categories/Horror';
echo basename($url);

Here is the format of affiliate URL I have http://tracking.vcommission.com/aff_c?offer_id=2119&&url=http%3A%2F%2Fwww.netmeds.com%2F%3Fsource_attribution%3DVC-CPS-Emails%26utm_source%3DVC-CPS-Emails%26utm_medium%3DCPS-Emails%26utm_campaign%3DEmails
If you see it has 2 URLs:
first URL: is for vcommission.com and
Second URL: netmeds.com
I have CSV file with lot of rows. Each rows may have different second URL. I wanted to get second URL for each rows. First URL is also not static as for different CSV, this would also different.
How can I get second URL?
Some basic string parsing like this should give you an idea.
$url='http://tracking.vcommission.com/aff_c?offer_id=2119&&url=http%3A%2F%2Fwww.netmeds.com%2F%3Fsource_attribution%3DVC-CPS-Emails%26utm_source%3DVC-CPS-Emails%26utm_medium%3DCPS-Emails%26utm_campaign%3DEmails';
list($u,$q)=explode('url=',urldecode($url));
$o=(object)parse_url($q);
echo $o->host;
A good way to find the domain for a URL is with parse_url
Unfortunately due to the way your data is stored this is not really an option however you may be able to use some sort of regex to find contained web addresses in the query string
<?php
$url = "http://tracking.vcommission.com/aff_c?offer_id=2119&&url=http%3A%2F%2Fwww.netmeds.com%2F%3Fsource_attribution%3DVC-CPS-Emails%26utm_source%3DVC-CPS-Emails%26utm_medium%3DCPS-Emails%26utm_campaign%3DEmails";
$p = parse_url($url);
$pattern = "/www[^%]*/";
preg_match($pattern, $p['query'], $result);
var_dump($result);
You may need to adjust the regex pattern based on how the other data presents itself.
The problem i'm facing right now is im getting a URL, like so:
www.example.com/example.php?url=www.google.com
now the problem is, if theres a get in my url, like so:
www.example.com/example.php?url=www.google.com?id=1
it doesn't actually cause a problem yet, but if theres two GET vars in the my URL, it doesn't know where the "and" goes, the first get or the second one, and basically just chooses the first, ex:
www.example.com/example.php?url=www.google.com?id=1&username=me
is there a workaround? I could recode a lot of things to have it as one get variable, but it'll involve a lot of work and I wish i could have a solution!
thanks!
Heres my code:
$facebookapi=new facebook(array('appId'=>'*******','secret'=>'********','fileUpload'=>'false'));
$url='http://******.com/questions/view.php?id=884&username=robot';
$facebookapi->api('/me/******app:answer?question=' . urlencode($url),'POST');
You need urlencode to encode the url parameter.
$url = 'www.google.com?id=1';
echo 'www.example.com/example.php?url='.urlencode($url).'&username=me';
Edit:
After seeing your posted code, it seems that you should use the third parameter for params.
$url='http://******.com/questions/view.php?id=884&username=robot';
$facebookapi->api('/me/******app:answer', 'POST', array('question' => $url));
Well the function urlencode is perfect for this.
Once the url is encoded,
The first get variable will turn from this
www.google.com?id=1&username=me
to this
www.google.com%3Fid%3D1&6username=me
Your website will then appear as [www.example.com/example.php?url=www.google.com%3Fid%3D1%26username%3Dme]
Once PHP receives that variable you can decode it
$url = urldecode($_GET['url']);
Note: some versions of PHP do it automatically.
I know that I should encodeURI any url passed to anything else, because I read this:
http://www.digitalbart.com/jquery-and-urlencode/
I want to share the current time of the current track I am listening to.
So I installed the excellent yoururls shortener.
And I have a bit of code that puts all the bits together, and makes the following:
track=2&time=967
As I don't want everyone seeing my private key, I have a little php file which takes the input, and appends the following, so it looks like this:
http://myshorten.example/yourls-api.php?signature=x&action=shorturl&format=simple&url=http://urltoshorten?track=2&time=967
So in the main page, I call the jquery of $("div.shorturl").load(loadall);
It then does a little bit of CURL and then shortener returns a nice short URL.
Like this:
$myurl='http://myshorten.example/yourls-api.php?signature=x&action=shorturl&format=simple&url=' . $theurl;
$ch = curl_init($myurl);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
$data = curl_exec($ch);
curl_close($ch);
if ($data === false) {
echo 'cURL failed';
exit;
}
echo $data;
All perfect.
Except... the URL which is shortened is always in the form of http://urltoshorten?track=2 - anything after the ampersand is shortened.
I have tried wrapping the whole URL in php's URLencode, I've wrapped the track=2&time=967 in both encodeURI and encodeURIComponent, I've evem tried wrapping the whole thing in one or both.
And still, the & breaks it, even though I can see the submitted url looks like track=1%26time%3D5 at the end.
If I paste this or even the "plain" version with the unencoded url either into the yoururls interface, or submit it to the yoururls via the api as a normal URL pasted into the location bar of the browser, again it works perfectly.
So it's not yoururls at fault, it seems like the url is being encoded properly, the only thing I can think of is CURL possibly?
Now at this point you might be thinking "why not replace the & with a * and then convert it back again?".
OK, so when the url is expanded, I get the values from
var track = $.getUrlVar('track');
var time = $.getUrlVar('time');
so I COULD lose the time var, then do a bit of finding on where the * is in track and then assume the rest of anything after * is the time, but it's a bit ugly, and more to the point, it's not really the correct way to do things.
If anyone could help me, it would be appreciated.
I have tried wrapping the whole URL in php's URLencode
That is indeed what you have to do (assuming by ‘URL’ you mean inner URL being passed as a component of the outer URL). Any time you put a value in a URL component, you need to URL-encode, whether the value you're setting is a URL or not.
$myurl='http://...?...&url='.rawurlencode($theurl);
(urlencode() is OK for query parameters like this, but rawurlencode() is also OK for path parts, so unless you really need spaces to look slightly prettier [+ vs %20], I'd go for rawurlencode() by default.)
This will give you a final URL like:
http://myshorten.example/yourls-api.php?signature=x&action=shorturl&format=simple&url=http%3A%2F%2Furltoshorten%3Ftrack%3D2%26time%3D967
Which you should be able to verify works. If it doesn't, there is something wrong with yourls-api.php.

Maybe an explanation of how HTTP variables work will help you out.
If I'm getting a page with the following variables and values:
var1 = Bruce Oxford
var2 = Brandy&Wine
var3 = ➋➌➔ (unicode chars)
We uri-encode the var name and the value of the var, ie:
var1 = Bruce+Oxford
var2 = Brandy%26Wine
var3 = %E2%9E%8B%E2%9E%8C%E2%9E%94
What we are not doing is encoding the delimiting charecters, so what the request data will look like for the above is:
?var1=Bruce+Oxford&var2=Brandy%26Wine&var3=%E2%9E%8B%E2%9E%8C%E2%9E%94
Rather than:
%3Fvar1%3DBruce+Oxford%26var2%3DBrandy%26Wine%26var3%3D%E2%9E%8B%E2%9E%8C%E2%9E%94
Which is of course just gibberish.
