以下代码：
$zip = new ZipArchive();
if ($zip->open('./archive.zip',ZIPARCHIVE::CREATE) !== TRUE) {
die ("Could not open archive");
}
$iterator = new RecursiveIteratorIterator(new RecursiveDirectoryIterator("./folder/"));
foreach ($iterator as $key => $value) {
try {
$zip->addFile(realpath($key),$key);
echo "'$key' successfully added.\n";
} catch (Exception $e) {
echo "ERROR: Could not add the file '$key': $e\n";
}
}
$zip->close();
Uncaught exception 'UnexpectedValueException' with message 'RecursiveDirectoryIterator::__construct(./some/path/): Failed to open dir: Too many open files' in /some/other/path/zip.PHP:24 Stack trace: #0 [internal function]: RecursiveDirectoryIterator->__construct('./some/path/') #1 /some/other/path/zip.PHP(24): RecursiveDirectoryIterator->getChildren() #2 {main} thrown in /some/other/path/zip.PHP on line 24
只需将迭代器转换为具有
原文链接：https://www.f2er.com/php/133803.htmliterator_to_array函数的数组,您似乎可以根据需要迭代任意数量的文件：
$iterator = new RecursiveIteratorIterator(new RecursiveDirectoryIterator("./folder/"));
$files = iterator_to_array($iterator,true);
// iterate over the directory
// add each file found to the archive
foreach ($files as $key => $value) {
try {
$zip->addFile(realpath($key),$key);
echo "'$key' successfully added.\n";
} catch (Exception $e) {
echo "ERROR: Could not add the file '$key': $e\n";
}
}
