How i can display the last numbers of a redirected url in php?
with redirected, i mean something like this
$nick=$_GET['nickname'];
$url='http://es.cheese.formice.com/mouse/' . $nick . '';
For example, if the url is script.php?nickname=Skyleter, will be http://es.cheese.formice.com/mouse/Skyleter, the problem here is it redirects to http://es.cheese.formice.com/mouse/Skyleter.17529827, (try yourself) so i want to display the numbers of the redirected url.
Wich, for me is 17529827
Is this possible?
Please dont say "the last 8 digits" like $variable = substr($url, -8); , so every nick has different ID.
Also ill like to display a custom error when input is value. [script.php and not script.php?nick=nick]
It displays "undefinex index" by default.
Thanks!
If it's always going to be numbers, you could use filter_var to easily pull them out.
$url = 'http://es.cheese.formice.com/mouse/Skyleter.17529827';
$id = filter_var($url, FILTER_SANITIZE_NUMBER_INT);
echo $id; // 17529827
If the nickname contains numbers though, this won't work. If the format stays that way (always ending with a dot and a set of numbers), then I guess you could use pathinfo and read that as the extension of your path.
$urlParts = pathinfo('http://es.cheese.formice.com/mouse/Skyleter1111.17529827');
echo $urlParts['extension'];
Since this url will redirect you, you will need to use curl to get the next one.
This will work:
<?php
$nick='Skyleter'; //$_GET['nickname'];
$url='http://es.cheese.formice.com/mouse/' . $nick;
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_HEADER, TRUE);
curl_setopt($ch, CURLOPT_FOLLOWLOCATION, FALSE);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, TRUE);
$a = curl_exec($ch);
if(preg_match('#Location: (.*)#', $a, $r))
$l = trim($r[1]);
$user_id = end((explode('.', $l)));
echo $user_id;
?>
It explodes the string at the last dot (.), which is what comes right before the ID.

I've been trying to write a simple script in PHP to pull off data from a ISBN database site. and for some reason I've had nothing but issues using the file_get_contents command.. I've managed to get something working for this now, but would just like to see if anyone knows why this wasn't working?
The below would not populate the $page with any information so the preg matches below failed to get any information. If anyone knows what the hell was stopping this would be great?
$links = array ('
http://www.isbndb.com/book/2009_cfa_exam_level_2_schweser_practice_exams_volume_2','
http://www.isbndb.com/book/uniform_investment_adviser_law_exam_series_65','

http://www.isbndb.com/book/yale_daily_news_guide_to_fellowships_and_grants'
); // array of URLs
foreach ($links as $link)
{
$page = file_get_contents($link);
#print $page;
preg_match("#<h1 itemprop='name'>(.*?)</h1>#is",$page,$title);
preg_match("#<a itemprop='publisher' href='http://isbndb.com/publisher/(.*?)'>(.*?)</a>#is",$page,$publisher);
preg_match("#<span>ISBN10: <span itemprop='isbn'>(.*?)</span>#is",$page,$isbn10);
preg_match("#<span>ISBN13: <span itemprop='isbn'>(.*?)</span>#is",$page,$isbn13);
echo '<tr>
<td>'.$title[1].'</td>
<td>'.$publisher[2].'</td>
<td>'.$isbn10[1].'</td>
<td>'.$isbn13[1].'</td>
</tr>';
#exit();
}
My guess is you have wrong (not direct) URLs. Proper ones should be without the www. part - if you fire any of them and inspect the returned headers, you'll see that you're redirected (HTTP 301) to another URL.
The best way to do it in my opinion is to use cURL among curl_setopt with options CURLOPT_FOLLOWLOCATION and CURLOPT_MAXREDIRS.
Of course you should trim your urls beforehands just to be sure it's not the problem.
Example here:
$curl = curl_init();
foreach ($links as $link) {
curl_setopt($curl, CURLOPT_URL, $link);
curl_setopt($curl, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($curl, CURLOPT_FOLLOWLOCATION, TRUE);
curl_setopt($curl, CURLOPT_MAXREDIRS, 5); // max 5 redirects
$result = curl_exec($curl);
if (! $result) {
continue; // if $result is empty or false - ignore and continue;
}
// do what you need to do here
}
curl_close($curl);
For example, I want to curl 8 text files from http://example.com/0.txt to http://example.com/7.txt and echo them out, in a loop. The following is my current codes.
for ($i=0; $i < 6; $i++) {
$curl = curl_init();
$post_url = 'http://example.com/' . i . '.txt';
curl_setopt($curl, CURLOPT_URL, $post_url);
curl_setopt($curl, CURLOPT_HEADER, 0);
curl_setopt($curl, CURLOPT_RETURNTRANSFER, 1);
$data = curl_exec($curl);
curl_close($curl);
echo '<article>' . $data . '</article>';
}
It seems that traditionally the value of key CURLOPT_URL is supposed to directly written in the 4th line, but the way doesn't meet my demand. I tried separating the string with two dots and inserting the loop-controlling variable i into the two strings, to form the third parameter, but it doesn't work.
Then I tried bring the statement out from the line, and set a variable in advance which combines two strings and one number variable and place the variable in the curl_setopt() function as the third parameter. It doesn't work.
By the time I search "php curl loop" or "curl in loop with parameter" or something else, Google can hardly provide me with helpful information.
So eventually I am seeking help here : (
Thanks in advance if anyone would like to offer solution.
Not sure it can be because of typo but try fixing this & check,
$post_url = 'http://example.com/' . $i . '.txt'; // You miss '$' here

I am working on getting some xml data into a php variable so I can easily call it in my html webpage. I am using this code below:
$ch = curl_init();
$timeout = 5;
$url = "http://www.dictionaryapi.com/api/v1/references/collegiate/xml/define?key=0b03f103-f6a7-4bb1-9136-11ab4e7b5294";
$definition = simplexml_load_file($url);
echo $definition->entry[0]->def;
However my results are: .
I am not sure what I am doing wrong and I have followed the php manual, so I am guessing it is something obvious but I am just not understanding it correctly.
The actual xml results from that link used in cURL are visible by clicking the link below , I did not post it because it is rather long:

$timeout = 5;
$url = "http://www.dictionaryapi.com/api/v1/references/collegiate/xml/define?key=0b03f103-f6a7-4bb1-9136-11ab4e7b5294";
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($ch, CURLOPT_CONNECTTIMEOUT, $timeout);
$data = curl_exec($ch);
curl_close($ch); // you were missing a semicolon
$definition = new SimpleXMLElement($data);
echo '<pre>';
print_r($definition->entry[0]->def);
echo '</pre>';
// this returns the SimpleXML Object
// to get parts, you can do something like this...
foreach($definition->entry[0]->def[0] as $entry) {
echo $entry[0] . "<br />";
}

I'll try to be short: if you need more info, I'll tell you.
I'm using this code to get infos from Google Maps:
<?php
function getData($url) {
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_HEADER, 0); //Change this to a 1 to return headers
curl_setopt($ch, CURLOPT_USERAGENT, $_SERVER['HTTP_USER_AGENT']);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
$data = curl_exec($ch);
curl_close($ch);
return $data;
}
$url = 'http://maps.google.com/maps/geo?output=xml&q=' . urlencode($startPlace);
$url = 'http://maps.google.com/maps/api/geocode/json?sensor=false&gl=IT&address=' . urlencode($startPlace);
$xml = simplexml_load_string($this->getData($this->url)) or die("Error loading xml data");
$points = $xml->Response->Placemark->Point->coordinates;
$provincia = $xml->Response->Placemark->AddressDetails->Country->AdministrativeArea->SubAdministrativeArea->SubAdministrativeAreaName;
$regione =$xml->Response->Placemark->AddressDetails->Country->AdministrativeArea->AdministrativeAreaName;
echo $regione."<br>";
preg_match_all("/-*[0-9.]*(?=,)/", $points[0], $matches);
$longitude = $matches[0][0];
$latitude = $matches[0][2];
The code is used to retrieve infos about italian locations and till three days ago, all worked fine, but this morning I saw something strange: $regione returned by code ($xml->Response->Placemark->AddressDetails->Country->AdministrativeArea->AdministrativeAreaName;) had an english name.
Let's say the location found be a little town in Lombardia (where 'Lombardia' is the name of the Administrative Area), the Administartive Area name returned by Google Maps was no more 'Lombardia' but 'Lombardy'.
Since this data is used to search in a local database other places in the Administrative area and since the name used in the database is obviously italian name, application doesnìt work anymore.
I'll be grateful for any advice
The problem is solved using a different url, specifying language parameter:
'http://maps.google.com/maps/api/geocode/xml?sensor=false&language=IT&address=' . urlencode($startPlace);
This url type return correct results but defferently formed so it is necessary change the code to access the infos and put them into variables, but this solved my problem
I need to encode only part of the $delete path. Only the # in the email address and # in the property. I know how to use urlencode for the whole thing but not on just that. The way it works, is it loops through to get the properties and most of them include # in the name. Anyone who can help modify so that this works would be greatly appreciated!
The delete:
$delete = "http://admin:12345#192.168.245.133/#api/deki/DELETE:users/$user_id/properties/%s";
Here you can see $user_id this will be an email address BUT the # symbol needs to be encoded.
The properties which follow at the very end, has a # within the name, this needs to also be encoded. For example, one property name userprofile#external.created_date
Here is the code so far:
<?php
$user_id="john_smith#ourwiki.com";
$url=('http://admin:12345#192.168.245.133/#api/deki/users/=john_smith#ourwiki.com/properties');
$xmlString=file_get_contents($url);
$delete = "http://admin:12345#192.168.245.133/#api/deki/DELETE:users/$user_id/properties/%s";
$xml = new SimpleXMLElement($xmlString);
function curl_fetch($url,$username,$password,$method='DELETE')
{
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_CUSTOMREQUEST, $method);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, TRUE); // returns output as a string instead of echoing it
curl_setopt($ch,CURLOPT_USERPWD,"$username:$password"); // if your server requires basic auth do this
return curl_exec($ch);
}
foreach($xml->property as $property) {
$name = $property['name']; // the name is stored in the attribute
curl_fetch(sprintf($delete, $name),'admin','12345');
}
?>
Have you tried this? str_replace($string, array('#', '#'), array('%40', '%23'));
The urlencode function does not allow you to limit it to a subset of characters.
