示例

示例 #1 创建 Zip 归档

<?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();
?>

示例 #2 输出文档细节和列表

<?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";
?>

示例 #3 Zip 流封装,读取 OpenOffice 文件的元信息

<?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);
?>

此例使用了旧的 API(PHP 4),它打开了 ZIP 文件归档,读取归档里的每个文件,并输出文件内容。此例用到的 test2.zip 文档是 ZZIPlib 源分布里测试文档中的一个。

示例 #4 Zip 使用范例

<?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);

}
?>
