Save image from url with curl and file_put_contents PHP

In your $_POST the content of the img src is coming in with certain special characters like & encoded as &.

If you open this URL in the browser, you get the same error: https://scontent.ftbs4-1.fna.fbcdn.net/v/t1.0-9/39900479_1856467244440953_5986986678919626752_n.jpg?_nc_cat=0&oh=6262ebe636e7328f0471af2820fd4050&oe=5C03BEC7.

You can reverse this escaping using html_entity_decode. If I change this line the curl works:

$img_link = html_entity_decode(array_pop($regexResult));

how to get image from curl

Your script is correctly written. I have tried and works fine, but you need to set image headers in order to let navigator show the image.

Example:

header("Content-Type: image/jpeg");

$url = 'https://images.nga.gov/en/web_images/constable.jpg';
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_HEADER, false);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);
curl_setopt($ch, CURLOPT_USERAGENT, 'Mozilla/5.0 (Windows NT 6.1) AppleWebKit/537.11 (KHTML, like Gecko) Chrome/23.0.1271.1 Safari/537.11');
$res = curl_exec($ch);
$rescode = curl_getinfo($ch, CURLINFO_HTTP_CODE); 
curl_close($ch) ;
echo $res;

But please note your image url is down, that's why you are getting 404 error.

Save image using cURL

As it turns out the problem was a simple one.

-The first clue was that the command in terminal was working but the same command with shell_exec() was returning an error.

-The second clue was that as delboy1978uk mentioned the error was not 401 not authenticated but a 403 non authorized.

So there had to be a problem with the URL or parameter.
I printed out the URL but found no error....
So long story short, the problem was with the special characters in the URL. When I printed the URL the browser displayed the & character correctly not as the function got it as a parameter &.

So if I feed URL to htmlspecialchars_decode() prior to run the command then it works flawlessly.

So lookout for special characters in the URL!

image download by php curl or file_get_content

First of all the link you provided is not an image. It outputs..

This XML file does not appear to have any style information associated with it. The document tree is shown below.

Tested & Works !

Below code reads an image from an URL, saves it and then opens/renders on browser.

<?php
$image ="http://blog.stackoverflow.com/wp-content/uploads/stackoverflow-logo-300.png";
$ch = curl_init($image);
curl_setopt($ch, CURLOPT_HEADER, 0);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($ch, CURLOPT_BINARYTRANSFER,1);
$rawdata=curl_exec ($ch);
curl_close ($ch);
$fp = fopen("test.jpg",'w');
fwrite($fp, $rawdata);
fclose($fp);
header ("Content-Type: image/png");
readfile("test.jpg");

OUTPUT :

Sample Image

If you want just to render it.. Do like this.

<?php
readfile("http://blog.stackoverflow.com/wp-content/uploads/stackoverflow-logo-300.png");
header ("Content-Type: image/png");

Downloading Images from list of URL to server using PHP

As the file doc says, the file's newlines are preserved in the resulting array:

Each element of the array corresponds to a line in the file, with the newline still attached.

Pass the FILE_IGNORE_NEW_LINES flag to the file(...) call.

Otherwise, most or all of your $line values will end with a '\n' or '\r' character.

You should probably also pass FILE_SKIP_EMPTY_LINES.

$lines = file( 'List.txt', FILE_IGNORE_NEW_LINES | FILE_SKIP_EMPTY_LINES ); //the list of image URLs
