Saving an image from a PHP URL using curl and PHP - php

Question

I have tried to download an image from a PHP link. When I try the link in a browser it downloads the image. I enabled curl and I set “allow_url_fopen” to true. I’ve used the methods discussed here Saving image from PHP URL but it didn’t work. I've tried "file_get_contents" too, but it didn't work.
I made few changes, but still it doesn’t work. This is the code
$URL_path='http://…/index.php?r=Img/displaySavedImage&id=68';
$ch = curl_init ($URL_path);
curl_setopt($ch, CURLOPT_HEADER, 0);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($ch, CURLOPT_BINARYTRANSFER,1);
$raw=curl_exec($ch);
curl_close ($ch);
$fp = fopen($path_tosave.'temp_ticket.jpg','wb');
fwrite($fp, $raw);
fclose($fp);
Do you have any idea to make it works? Please help. Thanks

Answer 1

<?php
if( ini_get('allow_url_fopen') ) {
//set the index url
$source = file_get_contents('http://…/index.php?r=Img/displaySavedImage&id=68');
$filestr = "temp_ticket.jpg";
$fp = fopen($filestr, 'wb');
if ($fp !== false) {
fwrite($fp, $source);
fclose($fp);
}
else {
// File could not be opened for writing
}
}
else {
// allow_url_fopen is disabled
// See here for more information:
// http://php.net/manual/en/filesystem.configuration.php#ini.allow-url-fopen
}
?>
This is what I used to save an image without an extension (dynamic image generated by server). Hope it works for you. Just make sure that the file path location is fully qualified and points to an image. As #ComFreek pointed out, you can use file_put_contents which is the equivalent to calling fopen(), fwrite() and fclose() successively to write data to a file. file_put_contents

You can use it as a function :
function getFile($url){
$ch = curl_init();
curl_setopt($ch, CURLOPT_HEADER, 0);
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($ch, CURLOPT_FOLLOWLOCATION, true);
$tmp = curl_exec($ch);
curl_close($ch);
if ($tmp != false){
return $tmp;
}
}
And to call it :
$content = getFile(URL);
Or save its content to a file :
file_put_contents(PATH, getFile(URL));

Answer 3

You're missing a closing quote and semicolon on the first line:
$URL_path='http://…/index.php?r=Img/displaySavedImage&id=68';
Also, your URL is in $URL_path but you initialise cURL with $path_img which is undefined based on the code in the question.

Answer 4

Why use cURL when file_get_contents() does the job?
<?php
$img = 'http://…/index.php?r=Img/displaySavedImage&id=68';
$data = file_get_contents( $img );
file_put_contents( 'img.jpg', $data );
?>
