PHP Link to session_destroy - hyperlink

I need to make a link that when clicked will run this in php:
session_destroy();
I know how to make a link in html, but I don't know how to make it interact with php. Thanks for any help.

For an example, you want to use this script for logging out.
Your HTML has to be something like this for "index.php" (just an example)
Log Out
Then on the "logout.php"
session_start(); //to ensure you are using same session
session_destroy(); //destroy the session
header("location:index.php"); //to redirect back to "index.php" after logging out
exit();
In case you want to use JavaScript, I can tell you that too?

<?php
// logout.php
session_destroy();
Then make a link to logout.php

all you need to do is call a PHP script, which calls that function.

How to get domain root url in Laravel 4?

I'm ready to scream how hard can this be? I've been trying for too long.
If I have http://www.example.com/more/pages/page.php or similar I want to be able to get
www.example.com.
Thats all. So I can use it as I please. This will of course change if on production or development so I want to ascertain it dynamically.
Request::root()
returns http://www.example.com/more/pages/page.php
URL::to('/')
returns http://www.example.com/more/pages/page.php
How do I get this? Why am I having so much trouble to do this??
UPDATE (2017-07-12)
A better solution is actually to use Request::getHost()
Previous answer:
I just checked and Request::root(); does return http://www.example.com in my case, no matter which route I'm on. You can then do the following to strip off the http:// part:
if (starts_with(Request::root(), 'http://'))
{
$domain = substr (Request::root(), 7); // $domain is now 'www.example.com'
}
You may want to double check or post more code (routes.php, controller code, ...) if the problem persists.
Another solution is to simply use $_SERVER['SERVER_NAME'].
You also may test any of these:
Request::server ("SERVER_NAME")
Request::server ("HTTP_HOST")
It seems better than making any treatment of
Request::root()
All right.
In Laravel 5.1 and later you can use
request()->getHost();
or
request()->getHttpHost();
(the second one will add port if it's not standard one)
My hint:
FIND IF EXISTS in .env:
APP_URL=http://yourhost.dev
REPLACE TO (OR ADD)
APP_DOMAIN=yourhost.dev
FIND in config/app.php:
'url' => env('APP_URL'),
REPLACE TO
'domain' => env('APP_DOMAIN'),
'url' => 'http://' . env('APP_DOMAIN'),
USE:
Config::get('app.domain'); // yourhost.dev
Config::get('app.url') // http://yourhost.dev
Do your magic!
This is for Laravel 5.1 and I am not sure does it work for earlier versions but if somebody search on Google and lands here it might be handy in middleware handle function gets $request parameter:
$request->server->get('SERVER_NAME')
outside of middleware handle method you can access it by helper function request()
request()->server->get('SERVER_NAME')
use directly where you want controller or web.php
Request::getHost();
I think you can use asset('/')

How to detect all the urls of a website?

I wonder how to detect all the urls of a specified website, let's say, I know the website of https://stackoverflow.com/, how can I know that it has some urls like https://stackoverflow.com/questions and https://stackoverflow.com/tags, is there a method or a tool to know the result?
There are some possibilities:
If u don't want to write code you can use something like Xenu or Webspider to scan or save a website.
If you want to use it as part of your own tool you can write it in PHP:
Directory listening on foreign server is on:
$dir = "stackoverflow.com/";
foreach(scandir($dir) as $file){
print ''.$file.'<br>';
}
Directory listening is of:
Then you need to open the site per php_get_contents and filter for links per preg_match.

How to do Soundcloud Auth Dance in JS with a Redirect_URL that has GET Params

** I am currently implementing fancy URLs to see if these 'solves' this. eg /me/soundcloudconnect rather than index.php?c=me&a=soundcloudconnect via mod_rewrite **
I have been using the Soundcloud JS SDK and SC.Connect() etc function(s) which automates much of the Auth process. I have been using a Normal html file: sc.html which worked fine and allowed me to get /me/ and /me/tracks etc.
However I now realise? that I will need to perform Auth myself as I need to add a State variable as documented below, so that it prepends these params to the end of the Redirect_URI.
http://groups.google.com/group/soundcloudapi/browse_thread/thread/7bddbc296f3b80af
The URL that I am trying to redirect back to is:
index.php?c=me&a=soundcloudconnect
which is the 'me' controller and 'soundcloudconnect' action.
So could someone please point me in the right direction?
Either I want to be able to use SC.Connect() etc (but also be able to get and save Token) as well as redirect back to the URI above
Or, I need to do the same thing (Auth and store token) but not using SC.Connect() but normal JS instead.
I read that Soundcloud Developer support is via Stackoverflow - so hopefully someone can help?
The normal HTML file with working SC Auth:
http://socialartist.co/sc.html
The dynamic page which does not work with SC Auth:
http://socialartist.co/index.php?c=me&a=soundcloudconnect#
The issue is probably that those query parameters are interfering with the original url. E.g. http://www.soundcloud.com/register/?token=blagha23412&redirect_uri=http://anydomain.com/index.php?c=me&a=soundcloudconnect
How would SoundCloud distinguish between your parameters and its parameters? You might be able to wrap the redirect_uri value in quotes.
An alternative might be to use the path as your parameters. E.g. http://anydomain.com/index.php/me/soundcloudconnect and then you should be able to grab whatever you need out of the path on your server.
** SOLVED!! **
If you need to pass parameters to SC connect/auth then the only way to do this is to setup fancy urls via mod_rewrite.
There 'seems' to be another method here, but you need to be doing the Auth in 2 steps and not via SC.Connect.
http://groups.google.com/group/soundcloudapi/browse_thread/thread/7bddbc296f3b80af
I was trying to get URL_redirect to work with:
index.php?c=me&a=soundcloudconnect
But in the End just used Fancy URLs which worked
http://socialartist.co/me/soundcloudconnect

URL for a link to Twitter for a specific tweet

I have some Javascript that uses Twitter API to get tweets. I parse the data and use jQuery to generate HTML for the DOM.
An aspect of what I want to display is a "View this tweet" link -- yeah, sorta sounds silly, but it allows a user to get a URL for a specific tweet.
I am generating an a tag with an href. The URL is of the form:
http://twitter.com/{twitter-user-id}/status/{tweet-status-id}
where the content in curly braces is actual data extracted from the tweet (no, I am not including the curly braces). For example:
http://twitter.com/Atechtrader/status/57432099984130050
What happens in operation is that this works for some tweets, but not others. For the ones that fails, the Twitter server responds with content that says the requested page does not exist.
Am I doing something wrong?
https://twitter.com/statuses/ID should work.
it will redirect to the needed status.
Unfortunately, all of the answers provided so far rely on an HTTP redirect.
The direct link is of the form: https://twitter.com/i/web/status/{tweet-status-id}
FYI: id_str is the variable you need to call instead of id
id_str should be taken from the tweet object and replaced in
https://twitter.com/statuses/[id_str]
You can use like:
http://twitter.com/itdoesnotmatter/status/[YOURID]
Twitter redirect based on status ID not username.
It works for desktop and mobile.
You can use
'https://www.twitter.com/'+ user.screen_name+'/status/' + id_str
I've been tried it. It's work good:
- Web : https://twitter.com/statuses/ID
- Mobile && Web: https://twitter.com/User_ID/statuses/Tweet_ID
I hope it's helpful for you.

Connect to URL and dump webpage in Groovy

I would like to open a webpage from groovy, dump the specified webpage and eventually dump the webpage behind an anchor tag.
Does anybody has some sample code for this?
here is a variation
println 'http://www.google.com'.toURL().text
This is a good example
http://docs.codehaus.org/display/GROOVY/Simple+file+download+from+URL
Basically you want to do something like
def data = new URL(feedUrl).getText()
