PHP read a text file from a directory of zip files

Question

I have a directory which contains a set of zipped files. each of these files has foo.txt file in it.

How can I read this text file from each zip?

I know glob is used to list all files from the directory

Answer 1

PHP has an extension that allows you to work with ZIP archives.

Note that to access that one file you don't need to unzip the whole archive. The ZipArchive::extractTo method allows you to specify what to extract.

$zip = new ZipArchive;
$res = $zip->open('test.zip');
$zip->extractTo('my/extract/folder/', 'foo.txt');

Answer 2

You can use the PHP zip extension as:

foreach(glob('*.zip') as $zipFile) {

        $zip = new ZipArchive;

        if ($zip->open($zipFile) === TRUE) {

                // get the filename without extension.
                $filename = pathinfo($zipFile,PATHINFO_FILENAME);

                // extract.
                $zip->extractTo($filename);
                $zip->close();
                echo "Extracted contents of $zipFile to $filename","\n";
        } else {
                echo "Failed to open $zipFile","\n";   
        }
}

Answer 3

As far as I know compressed data can't be accessed this way, and you'd have to unzip it first.

If you're comfortable though, you can use this PHP extension: http://www.php.net/manual/en/book.zip.php

Answer 4

Have you taken a look at P HP5's ZipArchive functions?

// you could extract the txt-file only and read in the content afterwards
$value = 'myzipfile.zip';
$entry = $zip->getNameIndex('foo.txt');
                copy('zip://'.dirname(__FILE__).'/zip_files/'.$value.'#'.$entry, 'txt_files/'.$value.'.txt');
} 
$zip->close();

// now you can access the file and do with the content what everyou like
