Currently, I am utilizing the following code to download a zip file from an external server that contains more than 1,000 images. The process of downloading and creating/copying the source zip file onto my server is successful, but for some reason, the code stops executing at this point. The expected output from the if else statement below does not appear.
Initially, I had set CURLOPT_TIMEOUT to 240, however, this proved to be insufficient as it would result in a curl timeout error. Given that the zip file is close to 100MB in size, I estimated that the process would take around 15 minutes to complete. Hence, I adjusted CURLOPT_TIMEOUT to 1200 considering the varying sizes of the source zip file on a daily basis.
Any insights on why the code ceases to function? Are there any specific settings that require modification?
$source_photos_file = 'source_photos_file.zip';
$curl = curl_init();
$destination_photos_file = fopen($_SERVER['DOCUMENT_ROOT'].'/files/photos.zip', 'w');
curl_setopt($curl, CURLOPT_URL, FTP_URL.$source_photos_file); #input
curl_setopt($curl, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($curl, CURLOPT_CONNECTTIMEOUT, 30);
curl_setopt($curl, CURLOPT_TIMEOUT, 1200);
curl_setopt($curl, CURLOPT_FILE, $destination_photos_file); #output
if (curl_exec($curl) === false)
{
echo '<p>Curl error: ' .curl_error($curl). ' - error # '.curl_errno($curl).'</p>';
}
else
{
echo '<p>Execution completed without any errors</p>';
}
curl_close($curl);
fclose($destination_photos_file);
$photos_unzip_result = shell_exec('unzip -P password '.$_SERVER['DOCUMENT_ROOT'].'/files/photos.zip -d '.$_SERVER['DOCUMENT_ROOT'].'/files/pics_test/');
