Примеры
Пример #1 Создание Zip архива
<?php
$zip = new ZipArchive();
$filename = "./test112.zip";
if ($zip->open($filename, ZipArchive::CREATE)!==TRUE) {
exit("Невозможно открыть <$filename>\n");
}
$zip->addFromString("testfilephp.txt" . time(), "#1 Это тестовая строка, добавленная как testfilephp.txt.\n");
$zip->addFromString("testfilephp2.txt" . time(), "#2 Это тестовая строка, добавленная как testfilephp2.txt.\n");
$zip->addFile($thisdir . "/too.php","/testfromfile.php");
echo "numfiles: " . $zip->numFiles . "\n";
echo "status:" . $zip->status . "\n";
$zip->close();
?>
Пример #2 Собрать и отобразить подробную информацию об архиве
<?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";
?>
Пример #3 Использование обертки потока Zip, чтение мета-информации OpenOffice
<?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);
?>
Этот пример использует старую версию API (PHP 4), он открывает ZIP-архив, читает каждый файл в архиве и выводит его содержимое. Архив test2.zip, использованный в этом примере, является одним из тестовых архивов исходного дистрибутива ZZIPlib.
Пример #4 Пример использования Zip
<?php
$zip = zip_open("/tmp/test2.zip");
if ($zip) {
while ($zip_entry = zip_read($zip)) {
echo "Название: " . zip_entry_name($zip_entry) . "\n";
echo "Исходный размер: " . zip_entry_filesize($zip_entry) . "\n";
echo "Сжатый размер: " . zip_entry_compressedsize($zip_entry) . "\n";
echo "Метод сжатия: " . zip_entry_compressionmethod($zip_entry) . "\n";
if (zip_entry_open($zip, $zip_entry, "r")) {
echo "Содержимое файла:\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);
}
?>
Коментарии
<?php$zip = new ZipArchive;
$zip->open('teste.zip');
$zip->extractTo('./');
$zip->close();
echo "Ok!";
?>
All these examples will not work if the php script has no write access within the folder.
Although you may say this is obvious, I found that in this case, $zip->open("name", ZIPARCHIVE::CREATE) doesn't return an error as it might not try to access the file system but rather allocates memory.
It is only $zip->close() that returns the error. This might cause you seeking at the wrong end.
1) If you want to add files to a ZIP archive but you don't know if the ZiP file exists or not, you MUST check: this changes the way you open it !.
2) you can not append multiple flags, can use only one (or none).
If the zip does not exists, open it with:
$ziph->open($archiveFile, ZIPARCHIVE::CM_PKWARE_IMPLODE)
(or a different compression method)
If the zip already exists, open it with:
$ziph->open($archiveFile)
or
$ziph->open($archiveFile, ZIPARCHIVE::CHECKCONS)
Example: make backup files every hour and ZIP them all in a daily ZIP archive, so you want to get only one ZIP per day, each ZIP containing 24 files:
<?php
function archivebackup($archiveFile, $file, &$errMsg)
{
$ziph = new ZipArchive();
if(file_exists($archiveFile))
{
if($ziph->open($archiveFile, ZIPARCHIVE::CHECKCONS) !== TRUE)
{
$errMsg = "Unable to Open $archiveFile";
return 1;
}
}
else
{
if($ziph->open($archiveFile, ZIPARCHIVE::CM_PKWARE_IMPLODE) !== TRUE)
{
$errMsg = "Could not Create $archiveFile";
return 1;
}
}
if(!$ziph->addFile($file))
{
$errMsg = "error archiving $file in $archiveFile";
return 2;
}
$ziph->close();
return 0;
}
?>
you can use this code for reading JAR files (java archives)
JAR files use the same ZIP format, so can be easily read
$zf = zip_open(realpath('D:/lucene/allinone/lucene-core.jar')); $i=1;
while($zf && $ze = zip_read($zf)) {
$zi[$i]['zip entry name']= zip_entry_name($ze);
$zi[$i]['zip entry filesize']= zip_entry_filesize($ze);
$zi[$i]['zip entry compressed size']= zip_entry_compressedsize($ze);
$zi[$i]['zip entry compression method']= zip_entry_compressionmethod($ze);
$zi[$i]['zip entry open status'] = zip_entry_open($zf,$ze);
//$zi[$i]['zip entry file contents'] = zip_entry_read($ze,100);
$i++;
}
print_r($zi);
zip_close($zf);
