Images via cron

[Kudose]

Is there any reason the following code would work when accessed via browser but not via cron? Sorry for the commented code ... all of the methods produce the same result.

$toEncode = substr($img_url, strrpos($img_url, '/')+1);
                #echo $toEncode.'<br />';
                $url = substr($img_url, 0, strrpos($img_url, '/')+1);
                #echo $url.'<br />';
                $encoded = rawurlencode($toEncode);
                $img_url = $url . $encoded;
                #echo $img_url.'<br />';
                $img = file_get_contents($img_url, FILE_BINARY, NULL, 0, 1024000);
                #$h = fopen($img_url, "rb");
                #$img = fread($h, 102400);
                #fclose($h);
                #$curl = curl_init($img_url);
                #curl_setopt($curl, CURLOPT_RETURNTRANSFER, 1);
                #$img = curl_exec($curl);

            $file_name = str_replace(array(" ", '(', ')', '+', '!'), '_', rawurldecode($encoded));
            #echo $file_name.'<br />';
            #header('Content-type: image/jpeg');
            #echo $img;
            file_put_contents(LISTING_IMAGES_DIR.$file_name, $img);

TIA!

check the paths are not coming from some var such as $_SERVER which will be different between cl and via Apache.

I'm not using any superglobals.

Is the cron process using different credentials that perhaps don't have access to write data? Have you tried enabling error logging and setting error_reporting to E_ALL to try and trap any errors?

[Kudose]

The directory I am writing to is 777 and I have error_reporting(E_ALL) as my second line in the script.

I ran the script from the CLI as root and everything worked out, but su-ing to the user and running the script yielded broken images.

I'm a little confused.
