PHP Compression and archive-zip

This extension allows you to read and write the zip archive transparently and the files inside them.

After PHP5.2, in order to use these functions, you must use the--enable-zip configuration option to provide zip support when compiling PHP.

Example #1 Create a ZIP archive

<?php    $zip = new ziparchive ();    $filename = "./test112.zip";    if ($zip->open ($filename, ziparchive::create)!==true) {        exit ("Cannot open < $filename >\n");    }    $zip->addfromstring ("Testfilephp.txt". Time (),         "#1 This is a test string added as testfilephp.txt.\n");    $zip->addfromstring ("Testfilephp2.txt". Time (),         "#2 This is a test string added as testfilephp2.txt.\n");    $zip->addfile ($thisdir. "/too.php", "/testfromfile.php");    echo "Numfiles:". $zip->numfiles. "\ n";    echo "Status:". $zip->status. "\ n";    $zip->close ();? >

Example #2 output document details and list

<?php    $za = new ziparchive ();    $za->open (' Test_with_comment.zip ');    Print_r ($za);    Var_dump ($za);    echo "Numfiles:". $za->numfiles. "\ n";    echo "Status:". $za->status. "\ n";    echo "Statussys:". $za->statussys. "\ n";    echo "FileName:". $za->filename. "\ n";    echo "Comment:". $za->comment. "\ n";    for ($i =0; $i < $za->numfiles; $i + +) {        echo "index: $i \ n";        Print_r ($za->statindex ($i));    }    echo "Numfile:". $za->numfiles. "\ n";? >

Example #3 Zip Stream package to read meta information for a OpenOffice file

<?php    $reader = new XMLReader ();    $reader->open (' zip://'. DirName (__file__). '/test.odt#meta.xml ');    $odt _meta = Array ();    while ($reader->read ()) {        if ($reader->nodetype = = xmlreader::element) {            $elm = $reader->name;        } else {            if ($reader->nodetype = = Xmlreader::end_element && $reader->name = = ' Office:meta ') {break                ;            }            if (!trim ($reader->value)) {                continue;            }            $odt _meta[$elm] = $reader->value;        }    }    Print_r ($odt _meta);? >

This example uses the old API (PHP 4), which opens a ZIP file archive, reads each file in the archive, and outputs the contents of the file. The Test2.zip document used in this example is one of the test documents in the Zziplib source distribution.

Example #4 Zip Usage Example

<?php    $zip = Zip_open ("/tmp/test2.zip");    if ($zip) {while        ($zip _entry = Zip_read ($zip)) {            echo "Name:". Zip_entry_name ($zip _entry). "\ n";            echo "Actual Filesize:". Zip_entry_filesize ($zip _entry). "\ n";            echo "Compressed Size:". Zip_entry_compressedsize ($zip _entry). "\ n";            echo "Compression Method:". Zip_entry_compressionmethod ($zip _entry). "\ n";            if (Zip_entry_open ($zip, $zip _entry, "R")) {              echo "File contents:\n";              $buf = Zip_entry_read ($zip _entry, zip_entry_filesize ($zip _entry));              echo "$BUF \ n";              Zip_entry_close ($zip _entry);            }            echo "\ n";        }        Zip_close ($zip);    }? >
