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

Users can add texts. This texts can have links.
I'd like do add click to it.
The problem is, some links works like:
http://www.example.com
links that has no http will not work and will become:
http://mywebsite.com/www.example.com
any ideas how to solve it?
function toLink($titulo){
$url = '~(?:(https?)://([^\s<]+)|(www\.[^\s<]+?\.[^\s<]+))(?<![\.,:])~i';
$titulo = preg_replace($url, '$0', $titulo);
return $titulo;
}
Use preg_replace_callback instead and you can interrogate the match to see if you need to add the protocol.
function toLink($titulo) {
$url = '~(?:(https?)://([^\s<]+)|(www\.[^\s<]+?\.[^\s<]+))(?<![\.,:])~i';
$titulo = preg_replace_callback($url, function($matches) {
$url = $matches[0];
if (!preg_match('/^https?:\/\//', $url)) $url = 'http://'.$matches[0];
''.$url.'';
}, $titulo);
return $titulo;
}
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
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 ) ;
?>
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 )
I am trying to get the search keyword from a referrer url. Currently, I am using the following code for Google urls. But sometimes it is not working...
$query_get = "(q|p)";
$referrer = "http://www.google.com/search?hl=en&q=learn+php+2&client=firefox";
preg_match('/[?&]'.$query_get.'=(.*?)[&]/',$referrer,$search_keyword);
Is there another/clean/working way to do this?
Thank you,
Prasad
If you're using PHP5 take a look at http://php.net/parse_url and http://php.net/parse_str
Example:
// The referrer
$referrer = 'http://www.google.com/search?hl=en&q=learn+php+2&client=firefox';
// Parse the URL into an array
$parsed = parse_url( $referrer, PHP_URL_QUERY );
// Parse the query string into an array
parse_str( $parsed, $query );
// Output the result
echo $query['q'];
There are different query strings on different search engines. After trying Wiliam's method, I have figured out my own method. (Because, Yahoo's is using 'p', but sometimes 'q')
$referrer = "http://search.yahoo.com/search?p=www.stack+overflow%2Ccom&ei=utf-8&fr=slv8-msgr&xargs=0&pstart=1&b=61&xa=nSFc5KjbV2gQCZejYJqWdQ--,1259335755";
$referrer_query = parse_url($referrer);
$referrer_query = $referrer_query['query'];
$q = "[q|p]"; //Yahoo uses both query strings, I am using switch() for each search engine
preg_match('/'.$q.'=(.*?)&/',$referrer,$keyword);
$keyword = urldecode($keyword[1]);
echo $keyword; //Outputs "www.stack overflow,com"
Thank you,
Prasad
To supplement the other answers, note that the query string parameter that contains the search terms varies by search provider. This snippet of PHP shows the correct parameter to use:
$search_engines = array(
'q' => 'alltheweb|aol|ask|ask|bing|google',
'p' => 'yahoo',
'wd' => 'baidu',
'text' => 'yandex'
);
Source: http://betterwp.net/wordpress-tips/get-search-keywords-from-referrer/
<?php
class GET_HOST_KEYWORD
{
public function get_host_and_keyword($_url) {
$p = $q = "";
$chunk_url = parse_url($_url);
$_data["host"] = ($chunk_url['host'])?$chunk_url['host']:'';
parse_str($chunk_url['query']);
$_data["keyword"] = ($p)?$p:(($q)?$q:'');
return $_data;
}
}
// Sample Example
$obj = new GET_HOST_KEYWORD();
print_r($obj->get_host_and_keyword('http://www.google.co.in/search?sourceid=chrome&ie=UTF-&q=hire php php programmer'));
// sample output
//Array
//(
// [host] => www.google.co.in
// [keyword] => hire php php programmer
//)
// $search_engines = array(
// 'q' => 'alltheweb|aol|ask|ask|bing|google',
// 'p' => 'yahoo',
// 'wd' => 'baidu',
// 'text' => 'yandex'
//);
?>
$query = parse_url($request, PHP_URL_QUERY);
This one should work For Google, Bing and sometimes, Yahoo Search:
if( isset($_SERVER['HTTP_REFERER']) && $_SERVER['HTTP_REFERER']) {
$query = getSeQuery($_SERVER['HTTP_REFERER']);
echo $query;
} else {
echo "I think they spelled REFERER wrong? Anyways, your browser says you don't have one.";
}
function getSeQuery($url = false) {
$segments = parse_url($url);
$keywords = null;
if($query = isset($segments['query']) ? $segments['query'] : (isset($segments['fragment']) ? $segments['fragment'] : null)) {
parse_str($query, $segments);
$keywords = isset($segments['q']) ? $segments['q'] : (isset($segments['p']) ? $segments['p'] : null);
}
return $keywords;
}
I believe google and yahoo had updated their algorithm to exclude search keywords and other params in the url which cannot be received using http_referrer method.
Please let me know if above recommendations will still provide the search keywords.
What I am receiving now are below when using http referrer at my website end.
from google: https://www.google.co.in/
from yahoo: https://in.yahoo.com/
