我有点卡住了一个问题,我希望这里有人可以发光。
我正在使用一些函数来解压缩 .zip 文件及其文件夹,效果很好。但是,如果我尝试从任何其他目录使用该功能,它似乎不起作用或似乎没有创建文件夹 dirs 并写入文件。
我正在使用以下代码解压缩 .zip 文件。
<?PHP error_reporting(e_all);
include("../../includes/config.php");
/**
* Unzip the source_file in the destination dir
*
* @param string The path to the ZIP-file.
* @param string The path where the zipfile should be unpacked, if false the directory of the zip-file is used
* @param boolean Indicates if the files will be unpacked in a directory with the name of the zip-file (true) or not (false) (only if the destination directory is set to false!)
* @param boolean Overwrite existing files (true) or not (false)
*
* @return boolean Succesful or not
*/
function unzip($src_file, $dest_dir=false, $create_zip_name_dir=true, $overwrite=true)
{
if ($zip = zip_open($src_file))
{
if ($zip)
{
$splitter = ($create_zip_name_dir === true) ? "." : "/";
if ($dest_dir === false) $dest_dir = substr($src_file, 0, strrpos($src_file, $splitter))."/";
// Create the directories to the destination dir if they don't already exist
create_dirs($dest_dir);
// For every file in the zip-packet
while ($zip_entry = zip_read($zip))
{
// Now we're going to create the directories in the destination directories
// If the file is not in the root dir
$pos_last_slash = strrpos(zip_entry_name($zip_entry), "/");
if ($pos_last_slash !== false)
{
// Create the directory where the zip-entry should be saved (with a "/" at the end)
create_dirs($dest_dir.substr(zip_entry_name($zip_entry), 0, $pos_last_slash+1));
}
// Open the entry
if (zip_entry_open($zip,$zip_entry,"r"))
{
// The name of the file to save on the disk
$file_name = $dest_dir.zip_entry_name($zip_entry);
// Check if the files should be overwritten or not
if ($overwrite === true || $overwrite === false && !is_file($file_name))
{
// Get the content of the zip entry
$fstream = zip_entry_read($zip_entry, zip_entry_filesize($zip_entry));
file_put_contents($file_name, $fstream );
// Set the rights
chmod($file_name, 0777);
echo "save: ".$file_name."<br />";
}
// Close the entry
zip_entry_close($zip_entry);
}
}
// Close the zip-file
zip_close($zip);
}
}
else
{
return false;
}
return true;
}
/**
* This function creates recursive directories if it doesn't already exist
*
* @param String The path that should be created
*
* @return void
*/
function create_dirs($path)
{
if (!is_dir($path))
{
$directory_path = "";
$directories = explode("/",$path);
array_pop($directories);
foreach($directories as $directory)
{
$directory_path .= $directory."/";
if (!is_dir($directory_path))
{
//mkdir($directory_path);
my_ftp_mkdir2('httpdocs/templates/temp/', $directory_path);
//chmod($directory_path, 0777);
}
}
}
}
/* CHMOD with FTP */
function my_ftp_mkdir2 ($path, $dir) {
$server = "ftp.domainname.com";
// Connect to FTP server
$connection = ftp_connect ($server);
// Login on FTP server
$user = "username";
$pass = "password";
$result = ftp_login ($connection, $user, $pass);
if ((!$connection) || (!$result)) {
return false;
}
// Go to the dir thats been given
if (!@ftp_chdir ($connection, $path)) {
ftp_close($connection); // close FTP connection
return false;
}
// Create the map and set the rights
if (!@ftp_mkdir($connection, $dir)) {
ftp_close($connection); // close FTP connection
return false;
}
$chmod_cmd = "CHMOD 0777 " . $dir;
$chmod = ftp_site($connection, $chmod_cmd);
ftp_close($connection); // close FTP connection
return true;
}
if (!unzip("../user1/test2.zip", false, true, true)) {
echo 'The file has failed to be unzipped!';
} else {
echo 'The file has been unzipped!';
}
?>
现在这很好用。
但是我在测试目录中运行这个文件,如下所示:httpdocs/templates/temp/unzip.php
名为 test2.zip 的文件位于:httpdocs/templates/user1/test2.zip
因此,当我运行脚本时,它会执行以下操作: httpdocs/templates/user1/test2/index.html httpdocs/templates/user1/test2/img/ 等等。
但是当我从 httpdocs/ 目录运行这个脚本时,它说它已经被解压缩但没有创建任何目录或任何东西。
我的 PHP 有安全模式,这就是为什么我使用 FTP 将目录更改为 777 以进行测试。
所以当我在 httpdocs/unzip.php 中运行这个脚本时
我这样调用函数。
<?php
if (!unzip("templates/user1/test2.zip", false, true, true)) {
echo 'The file has failed to be unzipped!';
} else {
echo 'The file has been unzipped!';
}
?>
但这似乎不起作用,我希望有人可以帮助我提供一些好的建议。谢谢!
