如果文件增长到大于 500MB，我遇到了 php zip 库的问题，导致错误 500，可能与内存有关...
但是我尝试对 zip 创建进行 cmd 行，这在我的服务器上运行良好。
<?php
set_time_limit(10000);
// Make Zip name
$zipname = "main_backup.zip";
// Make a zip file
$cmd = `zip -r $zipname * -x filelist.php -x $zipname`;
if($cmd){
echo 'zip created';
}
else{
echo 'failed';
}
unlink(__FILE__);
?>
我知道如何排除文件和文件夹，但是有没有办法使用这种方法根据修改时间仅压缩文件？
我已经用谷歌搜索了几个小时，结果是空的。
为此，这里是创建错误 500 的代码。我的网站大约 1.8GB，它总是在 500MB 时出错〜。我应该注意错误日志是空白的，所以我只是假设错误的原因是 RAM 限制问题。
<?php
$zip = new ZipArchive;
$zip_name = "test.zip";
$res = $zip->open($zip_name, ZipArchive::CREATE);
