I'm try to save some pictures from url to my server, but i'm not able to do it.
this is my code (it's standard, i've found on internet):
$ch = curl_init($url);
$fp = fopen($img, 'wb');
curl_setopt($ch, CURLOPT_FILE, $fp);
curl_setopt($ch, CURLOPT_HEADER, 0);
curl_exec($ch);
curl_close($ch);
fclose($fp);
but for each link i put inside $url variable, on my server is always saved a 26 byte image (that's not the original image).
What's wrong?
I can successfully download image using your curl code. It can happen that your server is not allowed to connect the outside web links.
This is a curl equivalent code that download images as well. I believe from your server, you can not download image using this code.
file_put_contents("img.jpg", file_get_contents("http://www.letteratu.it/wp-content/uploads/2014/03/cielo.jpg"));
Run your curl with verbose mode to see the curl's debug messages, and show that us.
curl_setopt($ch, CURLOPT_VERBOSE, 1);
I'm pretty sure you need to include the http:// in the URL. I'm fairly certain it thinks that it is a local file without it (i.e., an implicit file://).

I am trying to load an XML file, but for some reason I can't use a URL.
allow_url_fopen is set to On.
I used this, which didn't work:
$xml = simplexml_load_file("https://example.corn/test.xml");
But this does work:
$xml = simplexml_load_file("../test.xml");
I also tried file_get_contents:
$xml = file_get_contents("https://example.corn/test.xml");
and even cURL:
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, "https://example.corn/test.xml");
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
$xml = curl_exec($ch);
curl_close($ch);
For each example I am displaying the output with var_dump($xml);, which always shows bool(false) when using a URL and shows the correct XML data when using a local path.
I would just use the local path, but this is just for a test and the actual XML file I am going to fetch is from a different site.
I tested it on a local server and it worked, but on my hosted server, it doesn't work at all. They are using the same php.ini. My hosted server is using php-fpm, I'm unsure if that could be a factor, or if there is something that has to be changed with it.
This might be a configuration error that I am unaware of, because the code should work, and the link definitley exists, because I can click on it and see the correct xml in the browser.
What could be causing this issue?
Turns out that I had my openssl.cafile property set to some location that didn't exist.
For some reason no errors were showing when using the commands above.
I think the specified url is not valid or doesn't exist
Read about curl in the PHP docs
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, "http://www.example.com/");
curl_setopt($ch, CURLOPT_HEADER, 0);
curl_exec($ch);
curl_close($ch);
I want to upload the file from local to server using curl in php and without using the form (which is html).
My php version is 5.2.6.
I have tried many different way and make many research about (upload file to server using curl in php), but the solution in google cannot solve my problem.
Below is my code:
// open file descriptor
$fp = fopen ("user.com/user/fromLocal.txt", 'w+') or die('Unable to write a file');
// file to download
$ch = curl_init('C:/wamp/www/user/fromLocal.txt');
// enable SSL if needed
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);
// output to file descriptor
curl_setopt($ch, CURLOPT_FILE, $fp);
curl_setopt($ch, CURLOPT_FOLLOWLOCATION, TRUE);
// set large timeout to allow curl to run for a longer time
curl_setopt($ch, CURLOPT_TIMEOUT, 1000);
curl_setopt($ch, CURLOPT_USERAGENT, 'any');
// Enable debug output
curl_setopt($ch, CURLOPT_VERBOSE, true);
echo $ch;
echo $fp;
curl_exec($ch);
curl_close($ch);
fclose($fp);
Expected output:
The file can upload to server and view.
Actual output:
Unable to write the file
I think you miss important information.
fopen ("user.com/user/fromLocal.txt", 'w+')
this means nothing.
To send a file to the server the server has to be configured to accept a POST request and you have to send the file through that endpoint.
If you have a form, do you send it to: "user.com/user/fromLocal.txt" ??
You have to create the form data with curl and send it to a server ready to accept your request. There are different ways to accomplish that. And the most simple is exactly to send a form using curl and not the HTML. But absolutly you cannot write a file like that in a server.
I am trying to go through a basic curl example. I have a php file running on a server that seems to have curl properly installed and I have another empty text document on the server that I am trying to have information copied to. When I run the script by opening the php file, no information is written to the text file.
For the server, it says curl is enabled:
curl
cURL support enabled
cURL Information libcurl/7.15.5 OpenSSL/0.9.8b zlib/1.2.3 libidn/0.6.5
Here is the php file I am trying to run:
http://www.php.net/manual/en/curl.examples-basic.php
<?php
$ch = curl_init("http://www.example.com/");
$fp = fopen("example_homepage.txt", "w");
curl_setopt($ch, CURLOPT_FILE, $fp);
curl_setopt($ch, CURLOPT_HEADER, 0);
curl_exec($ch);
curl_close($ch);
fclose($fp);
?>
I have an empty file named "example_homepage.txt" in the same folder. Any idea what is going wrong?
Your script is working perfectly. A quick test with curl example.com shows that it returns no output. If you want to actually fetch content, try a real site like $ch = curl_init("http://www.google.com/");.
The address "www.example.com" is just that, an example. You're meant to replace it with something real.
I am using the twitter api to access some account details. It's been made clear that you can easily get the twitter account image:
http://a0.twimg.com/profile_images/1260994338/P3030586-2_bigger.jpg
However, when i try to copy() this image in PHP to my local server it doesn't work. It seems you can't even ping the address as 'could not find host'.
How can I copy the twitter account image to my local server?
$twitsImg ='http://a0.twimg.com/profile_images/1260994338/P3030586-2_bigger.jpg';
$twit=file_get_contents($twitsImg);
$new_img = basename($twitsImg);
file_put_contents($new_img,$twit);
The problem you are having is that the php ini-file variable allow_url_fopen is turned off, as it should be. You need to be using cURL to get the file. cURL is usually installed on web servers by default. This example works on my site:
<?php
function save_image($img,$path){
$ch = curl_init($img);
curl_setopt($ch, CURLOPT_HEADER, 0);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($ch, CURLOPT_BINARYTRANSFER,1);
$data=curl_exec($ch);
curl_close ($ch);
if(file_exists($path)){
unlink($path);
}
$fp = fopen($path,'x');
fwrite($fp, $data);
fclose($fp);
}
save_image("http://a0.twimg.com/profile_images/1260994338/P3030586-2_bigger.jpg","up/file2.jpg");
?>
Also make sure you have the right CHMOD (775) set on your destination folder.
I post pictures from other websites and I would rather have those on my servers, in case their server dies all of a sudden. Say the file is located at "www.www.www/image.gif", how would I copy it to my directory "images" safely?
I write in PHP.
Thanks!
The following should work:
// requires allow_url_fopen
$image = file_get_contents('http://www.url.com/image.jpg');
file_put_contents('/images/image.jpg', $image);
or the cURL route:
$ch = curl_init('http://www.url.com/image.jpg');
$fp = fopen('/images/image.jpg', 'wb');
curl_setopt($ch, CURLOPT_FILE, $fp);
curl_setopt($ch, CURLOPT_HEADER, 0);
curl_exec($ch);
curl_close($ch);
fclose($fp);
If your server is configured to support http:// file paths, you could use file_get_contents.
If that doesn't work, the second simplest way is by using curl for which you will certainly find full-fledged download scripts.
Some servers you pull images from may require a User-agent that shows that you are a regular browser. There is a ready-made class in the User Contributed Notes to curl that handles that, and provides a simple DownloadFile() function.
