我从前面的帖子中找到了下面的脚本，使用PHP创建一个ZIP文件。
这个脚本允许您创建一个zip文件，但是它不允许您在任何您想要的目录中创建它。这是原始代码。
<?php
// Config Vars
$sourcefolder = "uploads/output" ; // Default: "./"
$zipfilename = "myarchive.zip"; // Default: "myarchive.zip"
$timeout = 5000 ; // Default: 5000
// instantate an iterator (before creating the zip archive, just
// in case the zip file is created inside the source folder)
// and traverse the directory to get the file list.
$dirlist = new RecursiveDirectoryIterator($sourcefolder);
$filelist = new RecursiveIteratorIterator($dirlist);
// set script timeout value
ini_set('max_execution_time', $timeout);
// instantate object
$zip = new ZipArchive();
// create and open the archive
if ($zip->open("$zipfilename", ZipArchive::CREATE) !== TRUE) {
die ("Could not open archive");
}
// add each file in the file list to the archive
foreach ($filelist as $key=>$value) {
$zip->addFile(realpath($key), $key) or die ("ERROR: Could not add file: $key");
}
// close the archive
$zip->close();
echo "<br>Archive ". $zipfilename . " created successfully - ";
// And provide download link ?>
<a href="http:<?php echo $zipfilename;?>" target="_blank">Download <?php echo $zipfilename?></a>
我试着修改代码，以便能够决定脚本的目的地，因为我在互联网上花了几个小时后没有找到解决方案。一些解决方案建议在哪里改变$zipfilename = "myarchive.zip";到$zipfilename = "uploads/output/myarchive.zip";但在URL下载链接我想显示为:存档myarchive.zip创建成功-下载myarchive.zip不是作为存档上传/输出/myarchive.zip创建成功-下载myarchive.zip
因此，我尝试了这个代码，但它不适合我。我不知道我做错了什么。
<?php
// Config Vars
$sourcefolder = "uploads/output" ; // Default: "./"
$destfolder = "uploads/output/"; // Default: "myarchive.zip"
$zipfilename = "myarchive.zip"; // Default: "myarchive.zip"
$timeout = 5000 ; // Default: 5000
// instantate an iterator (before creating the zip archive, just
// in case the zip file is created inside the source folder)
// and traverse the directory to get the file list.
$dirlist = new RecursiveDirectoryIterator($sourcefolder);
$filelist = new RecursiveIteratorIterator($dirlist);
// set script timeout value
ini_set('max_execution_time', $timeout);
// instantate object
$zip = new ZipArchive();
// create and open the archive
if ($zip->open(''.$destfolder.''.$zipfilename.'', ZipArchive::CREATE) !== TRUE) {
die ("Could not open archive");
}
// add each file in the file list to the archive
foreach ($filelist as $key=>$value) {
$zip->addFile(realpath($key), $key) or die ("ERROR: Could not add file: $key");
}
// close the archive
$zip->close();
echo "<br>Archive ". $zipfilename . " created successfully - ";
// And provide download link ?>
<a href="http:<?php echo $zipfilename;?>" target="_blank">Download <?php echo $zipfilename?></a>
创建zip文件的静态方法示例:
//...
public static function zip($source, $destination)
{
if (!extension_loaded('zip') || !file_exists($source)) {
throw new 'Exception('zip not loaded');
}
$zip = new 'ZipArchive();
if ($zip->open($destination, 'ZIPARCHIVE::CREATE) === false) {
return false;
}
if (is_dir($source) === true) {
$files = new 'RecursiveIteratorIterator(
new 'RecursiveDirectoryIterator($source),
'RecursiveIteratorIterator::SELF_FIRST
);
foreach ($files as $file) {
if (in_array(substr($file, strrpos($file, DIRECTORY_SEPARATOR) + 1), array('.', '..'))) {
continue;
}
$file = realpath($file);
if (is_dir($file) === true) {
$zip->addEmptyDir(str_replace($source . DIRECTORY_SEPARATOR, '', $file . DIRECTORY_SEPARATOR));
} else {
if (is_file($file) === true) {
$zip->addFromString(
str_replace($source . DIRECTORY_SEPARATOR, '', $file),
file_get_contents($file)
);
}
}
}
} else {
if (is_file($source) === true) {
$zip->addFromString(basename($source), file_get_contents($source));
}
}
return $zip->close();
}
