Hello,
I need to compress files by PHP, and save them to a folder, I searched the web, but I just figured out how to compress a string.
For example: When the user accesses the URL x.php?arquivo=exemplo.jpg PHP will compress the exemplo.jpg file already on the server, and will save it to the compactados folder.
In php.net there are examples of how to package with the zip extension and bzip2 . In the previous bzip2 link, the example compresses a string. Then you can read the file as a string. Here's an example of php.net tailored to your situation:
<?php
$filename = "./testfile.bz2";
// open file for writing
$bz = bzopen($filename, "w");
// write string to file
//Aqui você coloca o caminho para o seu arquivo, para ser lido pelo file_get_contents
bzwrite($bz, file_get_contents('./team-member.jpg'));
// close file
bzclose($bz);
// open file for reading
$bz = bzopen($filename, "r");
// read 10 characters
echo bzread($bz, 10);
// output until end of the file (or the next 1024 char) and close it.
echo bzread($bz);
bzclose($bz);
?>
You can also zip in using the first example, also from php.net.
