Remove "http://" from URL string - php

I am using a bit.ly shortener for my custom domain. It outputs http://shrt.dmn/abc123; however, I'd like it to just output shrt.dmn/abc123.
Here is my code.
//automatically create bit.ly url for wordpress widgets
function bitly()
{
//login information
$url = get_permalink(); //for wordpress permalink
$login = 'UserName'; //your bit.ly login
$apikey = 'API_KEY'; //add your bit.ly APIkey
$format = 'json'; //choose between json or xml
$version = '2.0.1';
//generate the URL
$bitly = 'http://api.bit.ly/shorten?version='.$version.'&longUrl='.urlencode($url).'&login='.$login.'&apiKey='.$apikey.'&format='.$format;
//fetch url
$response = file_get_contents($bitly);
//for json formating
if(strtolower($format) == 'json')
{
$json = #json_decode($response,true);
echo $json['results'][$url]['shortUrl'];
}
else //for xml formatting
{
$xml = simplexml_load_string($response);
echo 'http://bit.ly/'.$xml->results->nodeKeyVal->hash;
}
}

As long as it is supposed to be url and if there is http:// - then this solution is the simplest possible:
$url = str_replace('http://', '', $url);

Change your following line:
echo $json['results'][$url]['shortUrl'];
for this one:
echo substr( $json['results'][$url]['shortUrl'], 7);

You want to do a preg_replace.
$variable = preg_replace( '/http:\/\//', '', $variable ); (this is untested, so you might also need to escape the : character ).
you can also achieve the same effect with $variable = str_replace('http://', '', $variable )

Extract particular point of URL in PHP

I'm trying to get a very specific part of a URL using PHP so that I can use it as a variable later on.
The URL I have is:
https://forums.mydomain.com/index.php?/clubs/11-Default-Club
The particular part I am trying to extract is the 11 part between the /clubs/ and -Default-Club bits.
I was wondering what the best way to do this was. I've seen examples on here that use a regex-esque parser but I can't wrap my head around it for this particular instance.
Thanks
Edit; this is what I've tried so far using an explode query, but it seems to give me all sorts of elements which are not present in the URL above:
$url = $_SERVER['REQUEST_URI'];
$url = explode('/', $url);
$url = array_filter($url);
$url = array_merge($url, array());
Which returns:
Array ( [0] => index.php?app=core&module=system&controller=widgets&do=getBlock&blockID=plugin_9_bimBlankWidget_dqtr03ssz&pageApp=core&pageModule=clubs&pageController=view&pageArea=header&orientation=horizontal&csrfKey=8e19769b95c733b05439755827a98ac8 )
If you expect that the string with dashes (11-Default-Club) will be always at the end you can try this:
$url = $_SERVER['REQUEST_URI'];
$urlParts = explode('/', $url);
$string = end($urlParts);
$stringParts = explode('-', $string);
$theNumber = $stringParts[0]; // this will be 11
I'd rather be explicit:
<?php
$url = 'https://forums.mydomain.com/index.php?/clubs/11-Default-Club';
$query = parse_url($url, PHP_URL_QUERY);
$pattern = '#^/clubs/(\d+)[a-zA-Z-]+$#';
$digits = preg_match($pattern, $query, $matches)
? $matches[1]
: null;
var_dump($digits);
Output:
string(2) "11"
If this URL structure is fix for all URLs in your site and you only want to get the integer/number/digit part of the URL:
<?php
$url = 'https://forums.mydomain.com/index.php?/clubs/11-Default-Club';
$int = (int) filter_var($url, FILTER_SANITIZE_NUMBER_INT);
echo $int;
If this url structure is fix for all URLs in your site then below is best way to get your value.
<?php
$url = "https://forums.mydomain.com/index.php?/clubs/11-Default-Club";
$url = explode('/', $url);
$url = array_filter($url);
$end = end($url);
$end_parts = explode('-',$end);
echo $end_parts[0];
Output:
11

Removing anchor (#hash) from URL

Is there any reliable way in PHP to clean a URL of anchor tags?
So input:
http://site.com/some/#anchor
Outputs:
http://site.com/some/
Using strstr()
$url = strstr($url, '#', true);
Using strtok()
Shorter way, using strtok:
$url = strtok($url, "#");
Using explode()
Alternative way to separate the url from the hash:
list ($url, $hash) = explode('#', $url, 2);
If you don't want the $hash at all, you can omit it in list:
list ($url) = explode('#', $url);
With PHP version >= 5.4 you don't even need to use list:
$url = explode('#', $url)[0];
Using preg_replace()
Obligatory regex solution:
$url = preg_replace('/#.*/', '', $url);
Using Purl
Purl is neat URL manipulation library:
$url = \Purl\Url::parse($url)->set('fragment', '')->getUrl();
There is also one other option with parse_url();
$str = 'http://site.com/some/#anchor';
$arr = parse_url($str);
echo $arr['scheme'].'://'.$arr['host'].$arr['path'];
Output:
http://site.com/some/
Alternative way
$url = 'http://site.com/some/#anchor';
echo str_replace('#'.parse_url($url,PHP_URL_FRAGMENT),'',$url);
Using parse_url():
function removeURLFragment($pstr_urlAddress = '') {
$larr_urlAddress = parse_url ( $pstr_urlAddress );
return $larr_urlAddress['scheme'].'://'.(isset($larr_urlAddress['user']) ? $larr_urlAddress['user'].':'.''.$larr_urlAddress['pass'].'#' : '').$larr_urlAddress['host'].(isset($larr_urlAddress['port']) ? ':'.$larr_urlAddress['port'] : '').$larr_urlAddress['path'].(isset($larr_urlAddress['query']) ? '?'.$larr_urlAddress['query'] : '');
}

Read tweets using PHP

I have a small problem with my tweets script. But for some reason, I don't know what the error could be. This is the error it gives me:
$url = "http://www.twitter.com/statuses/user_timeline/{$username}.xml?count={$number}";
$tweets = file_get_contents($url);
$feed = new SimpleXMLElement($tweets);
function time_stamp($date){
if (empty($date)){
return "No date provided";
}
and on the index.php page, it'll show this code:
<?php
$username = "user";//your twitter username
$number = 3;//number of tweets
include ("{$dir}/php/tweets.php");
?>
Do you guys know what it is that I'm doing wrong?
You don't need file_get_contents()
Try:
$url = "http://www.twitter.com/statuses/user_timeline/{$username}.xml?count={$number}";
$feed = simplexml_load_file($url);
Also, twitter made some changes not too long ago so your URL needs to look like this:
$url = "http://api.twitter.com/1/statuses/user_timeline/{$username}.xml?count={$number}";
Check this discussion.
You can use JSON easy and faster than XML
And to get content you can use
Curl => Faster
or
File_get_contents
Url
https://api.twitter.com/1/statuses/user_timeline.json?include_entities=true&include_rts=true&screen_name={screenname}&count={count}
like this
<?php
$url = 'https://api.twitter.com/1/statuses/user_timeline.json?include_entities=true&include_rts=true&screen_name=abdullaheid&count=3'
$x = file_get_contents( $url ) ; // Using file get contents
$object = json_decode( $x ) ;
$array = (array) $object ;
print_r( $array ) ;
?>

Detection - the title of the URL and the URL

How to detect, if there is any URL in the text and title it has (if any)?
If there is one, then it should change the URL:
from: http://stackoverflow.com
into:
<detected:url="http://stackoverflow.com"/>
I need also to retrieve titles from external links like this example:
<title:http://stackoverflow.com/="the actual title from the stackoverflow"/>
This is for single URL case:
$url = "http://www.stackoverflow.com/";
$check_result = get_detected_and_title( $url );
function get_detected_and_title( $url )
{
$detected = '<detected:url="'.$url.'"/>';
$title = '';
$tmp_html = file_get_contents( $url );
preg_match('/<title>(.*)<\/title>/', $tmp_html, $res);
$title = '<title:'.$url.'="'.$res[1].'"/>';
return array( $detected, $title );
}
Actually, after looking through SO's pages, I think this is more close to what you looking for. Although it needs some adjustment: How to mimic StackOverflow Auto-Link Behavior

Get the Youtube Video Thumbnail from Youtube video Url using PHP

Lets say I have a youtube video url www.youtube.com/watch?v=B4CRkpBGQzU&feature=youtube_gdata&par1=1&par2=2
I want to get the video thumbnail -> i3.ytimg.com/vi/B4CRkpBGQzU/default.jpg
I just need a simple php script that I will input the $url and get the $img
If posible I would like to strip all other parameters and be left with just the
www.youtube.com/watch?v=B4CRkpBGQzU as the $url
To extract the identifier from the following URL :
$url = 'www.youtube.com/watch?v=B4CRkpBGQzU&feature=youtube_gdata&par1=1&par2=2';
You can first use parse_url() to get the query string :
$queryString = parse_url($url, PHP_URL_QUERY);
var_dump($queryString);
Which, here, would give you :
string 'v=B4CRkpBGQzU&feature=youtube_gdata&par1=1&par2=2' (length=49)
And, then, use parse_str() to extract the parameters from that query string :
parse_str($queryString, $params);
var_dump($params);
Which would get you the following array :
array
'v' => string 'B4CRkpBGQzU' (length=11)
'feature' => string 'youtube_gdata' (length=13)
'par1' => string '1' (length=1)
'par2' => string '2' (length=1)
And, now, it's just a matter of using the v item from that array, injecting it into the thumbnail URL :
if (isset($params['v'])) {
echo "i3.ytimg.com/vi/{$params['v']}/default.jpg";
}
Which gives :
i3.ytimg.com/vi/B4CRkpBGQzU/default.jpg
<?php
function getYoutubeImage($e){
//GET THE URL
$url = $e;
$queryString = parse_url($url, PHP_URL_QUERY);
parse_str($queryString, $params);
$v = $params['v'];
//DISPLAY THE IMAGE
if(strlen($v)>0){
echo "<img src='http://i3.ytimg.com/vi/$v/default.jpg' width='150' />";
}
}
?>
<?php
getYoutubeImage("http://www.youtube.com/watch?v=CXWSlho1mMY&feature=plcp");
?>
$url = "http://youtube.com/watch?v=B4CRkpBGQzU";
$url = explode("&", $url);
$vidID = preg_match("|?v=(.*)|", $url);
$thumb_default = file_get_contents("http://img.youtube.com/vi/$vidID/default.jpg");
$thumb1 = file_get_contents("http://img.youtube.com/vi/$vidID/0.jpg");
$thumb2 = file_get_contents("http://img.youtube.com/vi/$vidID/1.jpg");
$thumb3 = file_get_contents("http://img.youtube.com/vi/$vidID/2.jpg");
$thumb4 = file_get_contents("http://img.youtube.com/vi/$vidID/3.jpg");
Assuming youtube doesn't change their format:
$thumb = preg_match('/watch\?v=(.*)&feature/',$url, $matches);
This will get you the 'B4CRkpBGQzU' part in $matches[1];
Getting the video ID from the URL
$url = "http://www.youtube.com/watch?v=oHg5SJYRHA0&feature=relate";
parse_str( parse_url( $url, PHP_URL_QUERY ) );
echo $vidID;//this is video id
Getting the images
$thumb1 = file_get_contents("http://img.youtube.com/vi/$vidID/0.jpg");
$thumb2 = file_get_contents("http://img.youtube.com/vi/$vidID/1.jpg");
$thumb3 = file_get_contents("http://img.youtube.com/vi/$vidID/2.jpg");
$thumb4 = file_get_contents("http://img.youtube.com/vi/$vidID/3.jpg");
