问题
Is there a way to add files to a zip file from another server with php's zip extension? ie.
addFile(array('localfile.txt,'http://www.domain.com/remotefile.txt'))
//(that obviously does not work)
I suppose I can download the files to a temporal folder and then add them to the zip file, but I was looking for a more automated solution or a function already made
回答1:
use file_get_contents() and ZipArchive::addFromString()
$zipArchiveInstance->addFromString($filename, file_get_contents($mediaUrl));
This writes the contents fetched remotely straight into your php object (no need to write/read temp file)
回答2:
It's not hard to read remote files in PHP.
file_get_contents("http://example.com/remote.txt");
Or to copy them locally:
copy("http://example.com/remote.txt", "/tmp/local.txt");
Whichever way you do it, the contents are going to have to be transferred to a local temp folder or memory before you can do anything with them.
回答3:
Fetch them with cURL, add them from TEMP directory.
