I am try to download image files from url from the following code, but it doesn't return the right content from the server. The image can be rendered in browser by loading the url or downloaded using curl in shell mode, but not in php execution. In php execution, the header's content type returned from the server is 'text/html' instead of 'image/jpeg' which it supposes to be.
Anyone has any ideas about this?
$url = 'http://count.koubei.com/showphone/showphone.php?f=jpg&w=104&h=10&bc=255,255,255&fc=0,0,0&fs=10&fn=arial&phone=LTIxMDM3MjIyOTc%3D%23dWBzmKEZpTh7YcWvOw%3D%3D';
$file_handler = fopen('phone.jpeg', 'w');
$curl = curl_init($url);
curl_setopt($curl, CURLOPT_FILE, $file_handler);
curl_setopt($curl, CURLOPT_HEADER, false);
curl_exec($curl);
curl_close($curl);
fclose($file_handler);
why not just use file_get_contents
like this
$img = file_get_contents("http://count.koubei.com/showphone/showphone.php?f=jpg&w=104&h=10&bc=255,255,255&fc=0,0,0&fs=10&fn=arial&phone=LTIxMDM3MjIyOTc%3D%23dWBzmKEZpTh7YcWvOw%3D%3D");
file_put_contents("photo.jpg",$img);

I'm trying to use php to download files that are created and downloaded when you call to a url.
In this case i'm trying to programmatically download a txt file from the dutch weather institute wich can be done by going to(in this example) this url http://projects.knmi.nl/klimatologie/daggegevens/getdata_dag.cgi?lang=nl&byear=2016&bmonth=6&bday=20&eyear=2016&emonth=6&eday=22&variabele=FHX&variabele=FXX&variabele=TG&variabele=TN&variabele=TX&stations=249&submit=Download+data+set
Going to that url downloads the file.
I want to do this with php so I can use the contents of the file to make custom charts.
Does anyone know how to do this with php?
Using file_get_contents(): http://php.net/manual/en/function.file-get-contents.php
or using CURL functions: http://php.net/manual/en/function.curl-exec.php
EDIT: CURL Solution:
$url = 'http://projects.knmi.nl/klimatologie/daggegevens/getdata_dag.cgi?lang=nl&byear=2016&bmonth=6&bday=20&eyear=2016&emonth=6&eday=22&variabele=FHX&variabele=FXX&variabele=TG&variabele=TN&variabele=TX&stations=249&submit=Download+data+set';
$curl = curl_init();
curl_setopt($curl, CURLOPT_URL, $url);
curl_setopt($curl, CURLOPT_RETURNTRANSFER, true);
curl_setopt($curl, CURLOPT_HEADER, false);
$str = curl_exec($curl);
Try:
$content = file_get_contents("The URL here");
echo $content;
i want to download image from this url
http://feelgrafix.com/959413-rococo.html
and this the source image
http://feelgrafix.com/data_images/out/28/959413-rococo.jpg
but when i download image from this source
file Download page url not download source image
this the code i used it
$url = 'http://feelgrafix.com/data_images/out/28/959413-rococo.jpg';
$ch = curl_init($imgURL);
$fp = fopen('image.gif', 'wb');
curl_setopt($ch, CURLOPT_FILE, $fp);
curl_setopt($ch, CURLOPT_HEADER, 0);
curl_setopt($ch, CURLOPT_FOLLOWLOCATION, true);
curl_exec($ch);
curl_close($ch);
fclose($fp);
and this Other way
$content = file_get_contents($url); file_put_contents('sadsdasd.jpg',$content);
i think that this the protect from server ..
no one can download OR see the image direct before open the page home
so what can i do ?
Instead of using curl function i recommend you to user file_get_content($url) to fetch the file and file_put_contents($path) to save it in your desired path and in case if any error it throws just usin # before both the function.
I am fetching data from API of a service provider (Say- http://serviceprovider.com).
From several parameter one is MP3 download Link (example- http://serviceprovider.com/storage/read?uid=475b68f2-a31b-40f8-8dfc-5af791a4d5fa_1_r.mp3&ip=255.255.255.255&dir=recording)
When I put this download link on my browser it saves it to my local PC.
Now My Problem -
I want to save this MP3 file in one of folder on my hosting space, from where I can further use it for playing using JPlayer Audio.
I have tried file_get_contents(), but nothing happened.
Thanks in advance.
Edit:
After reading Ali Answer I tried the following code, But still not working fully.
// Open a file, to which contents should be written to.
$fp = fopen("downloadk.mp3", "w");
$url = 'http://serviceprovider.com/storage/read?uid=475b68f2-a31b-40f8-8dfc-5af791a4d5fa_1_r.mp3&ip=255.255.255.255&dir=recording';
$handle = curl_init($url);
// Tell cURL to write contents to the file.
curl_setopt($handle, CURLOPT_FILE, $fp);
curl_setopt($handle, CURLOPT_RETURNTRANSFER, true);
curl_setopt($handle, CURLOPT_HEADER, false);
// Do the request.
$data = curl_exec($handle);
// Clean up.
curl_close($handle);
fwrite($fp, $data);
fclose($fp);
This created the file download.mp3 file on my server but with 0 bytes, i.e. empty.
The url used here is a download link example not a mp3 file that can be played with modern browser directly.
Function file_get_contents is used for reading local files. What you have is an URL and in order to fetch the contents, you need to do a HTTP request in your script. PHP comes with the curl extension, which provides you with a stable library of functions for doing HTTP requests:
http://php.net/manual/en/book.curl.php
Using curl to download your file could be done like this:
// Open a file, to which contents should be written to.
$downloadFile = fopen("download.mp3", "w");
$url = "http://serviceprovider.com/storage/read?uid=475b68f2-a31b-40f8-8dfc-5af791a4d5fa_1_r.mp3&ip=255.255.255.255&dir=recording";
$handle = curl_init($url);
// Tell cURL to write contents to the file.
curl_setopt($handle, CURLOPT_FILE, $downloadFile);
// Follow redirects.
curl_setopt($handle, CURLOPT_FOLLOWLOCATION, true);
// Do the request.
curl_exec($handle);
// Clean up.
curl_close($handle);
fclose($downloadFile);
You should probably add some error checking.
I have been using the following function to download pictures from a distributor for use on our website as was described here:
$url = "http://covers.stl-distribution.com/7819/lg-9781936417445.jpg";
$itemnum = 80848;
$path = "www.gullions.com/localstore/test/test.jpg";
header('Content-type: image/jpeg');
$ch = curl_init($url);
$fp = fopen("http://www.gullions.com/localstore/test/test.jpg", 'wb');
curl_setopt($ch, CURLOPT_FILE, $fp);
curl_setopt($ch, CURLOPT_HEADER, 0);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_exec($ch);
curl_close($ch);
fclose($fp);
Instead of downloading and saving the picture, it only prints crazy characters to the screen. I know that means that for some reason the browser is trying to render the picture but most likely doesn't recognize the file type. But I can't seem to find the problem. You can see the crazy output by navigating here. To verify that the image wasn't downloaded and saved, you can navigate here. Also, FTP also shows that no file was downloaded. If you navigate to the original picture's download url you'll see that the file we are trying to download does in fact exist.
I have contacted my host and verified that no settings have been changed with the server, that cURL is functioning properly, and have even rolled back my browser to verify that a recent update didn't cause the issue. I created a test file by removing the function from the application and have tried running it separately but have only had the same results.
Add:
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
as by default this parameter is false. Docs read:
TRUE to return the transfer as a string of the return value of
curl_exec() instead of outputting it out directly.
EDIT
Setting CURLOPT_RETURNTRANSFER make curl_exec() return data, so it should be written manually, like this:
$url = "http://covers.stl-distribution.com/7819/lg-9781936417445.jpg";
$ch = curl_init($url);
$fp = fopen("./test.jpg", 'wb');
curl_setopt($ch, CURLOPT_RETURNTRANSFER,true);
curl_setopt($ch, CURLOPT_HEADER, 0);
fwrite($fp, curl_exec($ch));
curl_close($ch);
fclose($fp);
Also this code, that uses CURLOPT_FILE works for me just fine:
$url = "http://covers.stl-distribution.com/7819/lg-9781936417445.jpg";
$ch = curl_init($url);
$fp = fopen("./test.jpg", 'wb');
curl_setopt($ch, CURLOPT_FILE, $fp);
curl_setopt($ch, CURLOPT_HEADER, 0);
curl_exec($ch);
curl_close($ch);
fclose($fp);
so I basically suspect that your file handle is not valid, therefore cURL falls back to default output. Try this code with elementary error checking (you should ALWAYS check for errors):
$url = "http://covers.stl-distribution.com/7819/lg-9781936417445.jpg";
$fp = fopen("./test.jpg", 'wb');
if( $fp != null ) {
$ch = curl_init($url);
curl_setopt($ch, CURLOPT_FILE, $fp);
curl_setopt($ch, CURLOPT_HEADER, 0);
curl_exec($ch);
curl_close($ch);
fclose($fp);
} else {
exit('ERROR: Failed to open file');
}
Note that my examples write to the same folder scripts sits in. It must work unless your server got file permissions messed badly. If it works for you, then investigate if (usually) user your scripts runs as can write to your target folder.
You haven't told your browser what type of file to expect, so it's probably defaulting to text/plain.
You need at least:
header('Content-type: image/jpeg');
As well, curl by default outputs whatever it fetches, unless you explicitly tell it you want to have the fetched data returned, or saved directly to file.
I know it’s possible to use imagecreatefromjpeg(), imagecreatefrompng(), etc. with a URL as the ‘filename’ with fopen(), but I'm unable to enable the wrappers due to security issues. Is there a way to pass a URL to imagecreatefromX() without enabling them?
I’ve also tried using cURL, and that too is giving me problems:
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL,"http://www.../image31.jpg"); //Actually complete URL to image
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
$data = curl_exec($ch);
curl_close($ch);
$image = imagecreatefromstring($data);
var_dump($image);
imagepng($image);
imagedestroy($image);
You can download the file using cURL then pipe the result into imagecreatefromstring.
Example:
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $imageurl);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1); // good edit, thanks!
curl_setopt($ch, CURLOPT_BINARYTRANSFER, 1); // also, this seems wise considering output is image.
$data = curl_exec($ch);
curl_close($ch);
$image = imagecreatefromstring($data);
You could even implement a cURL based stream wrapper for 'http' using stream_wrapper_register.
You could always download the image (e.g. with cURL) to a temporary file, and then load the image from that file.
