I have function for converting files and I want to run it as background process cuing curl.
$url = sendMessages.php;
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_FOLLOWLOCATION, 1);
$curled=curl_exec($ch);
curl_close($ch);
I used above code but didn't work.please advice?
Do I have to use full path url?
yes the url is expected to be a full url, that may look something like
$url = 'http://localhost/file/convertfiles.php';
the actual url really depends of your setup,
also you would probably be confronted to timeout issues, these can be overcome but I don't know enough about what you are trying to do or your setup to tell you how

Currently I have page say page1.php. Now in a certain event, I just want to run another link say http://example.com without actually refreshing this page. The link is a kind of script which updates my database. I tried using shell_exec('php '.$url); where $url='http://example.com' however it showed me an error that could not open file so I suppose shell_exec works only for internal files present on the server. Is there a way to do this directly or I have to go with AJAX? Thanks in advance
Try using curl to send the request to the server with php.
$url = 'http://example.com';
$ch = curl_init();
curl_setopt($ch, CURLOPT_AUTOREFERER, TRUE);
curl_setopt($ch, CURLOPT_NOBODY, TRUE);
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_FOLLOWLOCATION, TRUE);
curl_exec($ch);
curl_close($ch);
Alternatively you could try file_get_contents
file_get_contents('http://example.com');
I would do this front-end and I would use JSONP: much clean and safer IMHO.
I have a URL like this https://facebook.com/5 , I want to get HTML of that page, just like view source.
I tried using file_get_contents but that didn't returned me correct stuff.
Am I missing something ?
Is there any other function that I can utilize ?
If I can't get HTML of that page, what special thing did the developer do while coding the site to avoid this thing ?
Warning for being off topic
But does this task have be done using PHP?
Since this sounds like a task of web-scraping, I think you would gain more use in casperjs.
With this, you can target with precision what you would want to retrieved from the fb-page rather than grabbing the whole content, which I assume as of this writing is generated by multiple requests of content and rendered to you through a virtual DOM.
Please note that I haven't tried retrieving content from facebook, but I've done this with multiple services.
Good luck!
You may want to use curl instead: http://php.net/manual/en/curl.examples.php
Edit:
Here is an example of mine:
$url = 'https://facebook.com/5';
$ssl = true;
$ch = curl_init();
$timeout = 3;
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_CONNECTTIMEOUT, $timeout);
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, $ssl);
curl_setopt($ch, CURLOPT_FOLLOWLOCATION, true);
$data = curl_exec($ch);
curl_close($ch);
Note that depending on the websites vhost configuration a slash at the end of the url can make a difference.
Edit: Sorry for the undefined variable.. I copied it out of a helper method i used. Now it should be alright.
Yet another Edit:
curl_setopt($ch, CURLOPT_FOLLOWLOCATION, true);
By adding this option you will follow the redirects that are apperently happening in your example. Since you said it was an example I actually didnt run it before. Now I did and it works.
With permission from the other site, I am supposed to periodically download an image hosted on another site and include it in a collection of webcam photos on our site with an external link to the contributing site.
This hasn't been any issue for any of the other sites, but with this particular one, I can't open the image to resize it and save it to our server. It's not a hotlinking issue because I can create a plain ole' <img src="http://THEIRIMAGE /> on a page on our site and it works fine.
I've tried using $img = new Imagick($sourceFilePath) directly as with all the others, as well as trying to use PHP's copy and also trying to copy the image using cURL but when doing so, the page just times out with no results at all.
Here's the image in question: http://island-alpaca.selfip.com:10202/SnapshotJPEG?Resolution=640x480&Quality=Standard
Like I've said, I'm able to do this sort of thing with several other webcams, but it isn't working with this one, and I am stuck as to why it isn't. Any help would be greatly appreciated.
Thank you.
In order to reduce bandwidth and server load some sites block certain bots from accessing their content. Your cURL request needs to more closely mimic an actual browser, which would include a referrer (usually), user agent, etc. It could also be that there is a redirect and you haven't told cURL to follow redirects.
Try setting more opts like this:
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch,CURLOPT_ENCODING , "gzip");
curl_setopt($ch, CURLOPT_REFERER, $url);
curl_setopt($ch, CURLOPT_USERAGENT, 'PHP');
curl_setopt($ch, CURLOPT_HEADER, true);
curl_setopt($ch, CURLOPT_AUTOREFERER, true);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_FOLLOWLOCATION, true);
curl_setopt($ch, CURLOPT_TIMEOUT, 10);
If that doesn't work, get the user agent from an actual browser and put it in there and see if that makes a difference.
Try using file_get_contents().
for example:
$url = 'http://island-alpaca.selfip.com:10202/SnapshotJPEG?Resolution=640x480&Quality=Standard';
$outputfile = "tmp/image" . date("Y-m-d_H.i.s");
$cmd = "wget -q \"$url\" -O $outputfile";
exec($cmd);
$temp_img = file_get_contents($outputfile);
$img = new Imagick($temp_img);
Can you try this and get back to me?
I have following URL
http://www.davesinclairstpeters.com/auto2_inventorylist?i=37647&c=12452&npg=1&ns=50&echo=2
I want to retrieve content of this url using curl but everytime I make this request it is showing me error, as it is not passing required parameters
Below is my code
$ch = curl_init(); // start CURL
curl_setopt($ch, CURLOPT_URL, $json_url);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_HTTPGET, true);
curl_setopt($ch, CURLOPT_FRESH_CONNECT, true);
$response = curl_exec($ch);
That page doesn't give any information stating that the information isn't being passed properly. In fact, it tells you that the information has been recieved - by viewing the source, you can see:
<!--
javax.servlet.forward.request_uri = /auto2_inventorylist
...
javax.servlet.forward.servlet_path = /auto2_inventorylist
...
javax.servlet.forward.query_string = i=37647&c=12452&npg=1&ns=50&echo=2
-->
Which tells you the information has infact been recieved.
Therefore, it's no problem with your code, but with the website itself. You should make sure the URL you are using is valid, or contact that website to get more information.
With regards to your code itself - the curl_setopt($ch, CURLOPT_HTTPGET, true); isn't necessary, as this is already set by default, and you can also pass the URL as an argument of the curl_init function. Doesn't impact performance, but makes for neater code.
$ch = curl_init($json_url); // start CURL
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_FRESH_CONNECT, true);
$response = curl_exec($ch);
You code is perfectly fine and if there's something wrong returned, simply paste this URL to your web browser and check the result. In this case website simply failed for some reasons. There's nothing you can do about that as problem is NOT on your side.
This URL yields a page of cars with links to more cars. Looks like the URL you're starting with is old, or has some sort of expiration factor that's not obvious.
Not knowing which sort of filtering parameters you're shooting for.. hard to say what else my be wrong, other than your starting URL be bad.

Can you help me get this content spinning API working? It was wrote to work with C# but is there a way I can get it to work using PHP? I've been trying to post to the URL stated on that page using cURL, but all I'm getting back is a blank page. Here's the code I'm using:
$url = "http://api.spinnerchief.com/apikey=YourAPIKey&username=YourUsername&password=YourPassword";
// Some content to POST
$post_fields = "SpinnerChief is totally free. Not a 'lite' or 'trial' version, but a 100% full version and totally free. SpinnerChief may be free, but it is also one of the most powerful content creation software tools available. It's huge user-defined thesaurus means that its sysnonyms are words that YOU would normally use in real life, not some stuffy dictionary definition. And there's more...SpinnerChief can only get better, because we listen to our users, We take onboard your ideas and suggestions, and we update SpinnerChief so that it becomes the software YOU want!";
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_PORT, 9001);
curl_setopt($ch, CURLOPT_POST, 1);
curl_setopt($ch, CURLOPT_POSTFIELDS, $post_fields);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
$result = curl_exec($ch);
curl_close($ch);
echo $result;
Can anyone see something wrong I'm doing? Thanks a lot for the help.
The value for CURLOPT_POST should be 1, and the posted data should be set with CURLOPT_POSTFIELDS.
