Simple PHP function that can be used
to read data of a ZIP archive with PHP. The function receives a string with the path-name of the Zip file; and returns a two dimensional Array with data of each file in archive (name, actual_filesize, compressed_size).
<?php
// Function to Read ZIP Archive. Returns a two dimensional Array with data of each file in archive
function readZipData($zip_file) {
// PHP-MySQL Course - https://coursesweb.net/php-mysql/
$zip_data = array(); // will store arrays with data of each file in archive
$zip = zip_open($zip_file);
// if the $zip_file is opened, traverse the archive
if($zip) {
while ($zip_entry = zip_read($zip)) {
// adds in $zip_data an array with data of each file in archive
$zip_data[] = array(
'name' =>zip_entry_name($zip_entry),
'actual_filesize' => zip_entry_filesize($zip_entry),
'compressed_size' => zip_entry_compressedsize($zip_entry)
);
}
zip_close($zip);
return $zip_data;
}
else echo "Failed to open $zip_file";
}
/* Example */
//the path-name of the zip file
$zip_file = 'dir/file.zip';
// get data of the $zip_file
$zip_data = readZipData($zip_file);
// output the resulted array (with data for archived files)
echo '<pre>';
var_export($zip_data);
echo '</pre>';
?>
This example will return an array like this:
array (
0 =>
array (
'name' => 'file1.txt',
'actual_filesize' => 388984,
'compressed_size' => 114339,
),
1 =>
array (
'name' => 'image.jpg',
'actual_filesize' => 16942,
'compressed_size' => 16801,
),
2 =>
array (
'name' => 'audio/music.mp3',
'actual_filesize' => 16942,
'compressed_size' => 16806,
)
)
