generating-password-protected-zip-files-using-php.md

Alternative way of creating Password protected zip file when you are not ready to upgrade to php 7

<?php
$password = 'pass';
$outfile = 'download.zip';
$infile = 'file.txt';

header("Content-type: application/octet-stream");
header("Content-disposition: attachment; filename=$outfile");

@system("zip -P $password $outfile $infile");
readfile($outfile);
@unlink($outfile);

S3 Setting Expiration when uploading file

The answer from @Paras is good. But there is one thing that can confuse newcommers:

'options'     => [
    'Expires' => gmdate('D, d M Y H:i:s GMT', strtotime('+1 month')),
    >>> WRONG visibility' => 'public', WRONG <<<
]

If you want to define global options for the HEADERS, the options array is the right way to go. But if you also want to define the visibility, you can not mix it up. Visibility has to be define outside of options array.

👍

'visibility'  => 'public',
'options'     => ['Expires' => gmdate('D, d M Y H:i:s GMT', strtotime('+1 month'))]
