how to get image from url in php? - php

Question

I have one remote url which outputs the image
The url is in format like this
http://domain.com/my_file/view/<file_id>/FULL/
In the url "my_file" is a controller name, "view" is a function name and the other two are the parameters
If I hit this url in browser it shows me image
I want to take that image in my projects folder
I have tried with file_get_contents but it gives me warning with 404
How can I achieve that?

Answer 1

$img=file_get_contents('http://example.com/image/test.jpg');
file_put_contents('/your/project/folder/imgname.jpg',$img);
This works only if allow_url_fopen is set to 1 in your php.ini file.
If you can change this value, enable it and you're done.
Another option is CURL. Check if this module is enabled in your PHP configuration.
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, 'http://example.com/image/test.jpg');
curl_setopt($ch, CURLOPT_RETURNTRANSFER,1);
curl_setopt($ch, CURLOPT_HEADER , 0);
curl_setopt($ch, CURLOPT_VERBOSE, 0);
curl_setopt($ch, CURLOPT_TIMEOUT, 10);
$result = #curl_exec($ch);
$curl_err = curl_error($ch);
curl_close($ch);
if (empty($curl_err)) {
file_put_contents('/your/project/folder/imgname.jpg',$result);
}
If CURL is not enabled, your chance is to write a simple HTTP client like this:
$buf='';
$fp = fsockopen('example.com',80);
fputs($fp, "GET /image/test.jpg HTTP/1.1\n" );
fputs($fp, "Host: example.com\n" );
fputs($fp, "Connection: close\n\n" );
while (!feof($fp)) {
$buf .= fgets($fp,128);
}
fclose($fp);
file_put_contents('/your/project/folder/imgname.jpg',$buf);

Use Curl for this:
function curlFile($url)
{
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_HEADER, 0);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
$data = curl_exec($ch);
curl_close($ch);
return $data;
}
function readurl()
{
$url="http://domain.com/my_file/view/<file_id>/FULL/";
curlFile($url);
}
echo readurl();

If you are trying
$image = file_get_contents('http://domain.com/my_file/view/<file_id>/FULL/');
if($image) file_put_contents('some/folder/<file_id>');
and it does not work, it probably means either:
That there is access control that prevents it on the remote server. In that case, you must set the appropriate cookies. I suggest using curl to do that.
The image path is wrong; try to view source when navigating to http://domain.com/my_file/view/<file_id>/FULL/ using your browser.
The trailing / in your URL should not be there, e.g. http://domain.com/my_file/view/<file_id>/FULL?
