zip_close() 期望参数 1 是第 37 行给出的资源、对象

zip_close() expects parameter 1 to be resource, object given on line 37

我正在创建一个文件来提取 zip 文件。截断的代码检查文件扩展名是否为 .zip,然后检查文件是否已经存在。如果没有,请提取存档。

    if($fileExtension == "zip")
{
    if(is_dir("unzips/".$fileName) == false)
    {
        move_uploaded_file($_FILES["file"]["tmp_name"],"temp/".$_FILES["file"]["name"]);

        $zip = new ZipArchive();
        $zip -> open("temp/".$_FILES["file"]["name"]);

        for($num = 0; $num < $zip->numFiles; $num++)
        {
            $fileInfo = $zip->statIndex($num);
            echo "Successfully Extracted: ".$fileInfo["name"];
            $zip->extractTo("unzips/".$fileName);
            echo "<br />";
        }

        zip_close($zip);

        unlink("temp/".$_FILES["file"]["name"]);
    }
    else
    {
        echo $fileName." The ZIP archive file has already been unzipped";
    }
}
else
{
    echo "Only .zip files are allowed";
}

这是 index.php

void zip_close ( resource $zip )

zip

A ZIP file previously opened with zip_open().

http://php.net/manual/en/function.zip-close.php

$zipZipArchive() class 的实例。因此,您不能将其传递给 zip_close(),因为它需要使用 zip_open().

创建的资源

................................................ ...................................

编辑:我注意到在添加完整源代码后您的代码中还有另一个错误。

您为 $fileName 变量设置了无效值。

$array = explode(".",$_FILES["file"]["name"]);
$fileName = $array[0];

分解 $_FILES["file"]["name"] 并仅获得 $array[0] 值时,您仅获得文件名(不带扩展名)。

因此,当您将无效路径传递给 $zip->open($fileName); 方法时,它会 return 您出错:

ZipArchive::close(): Invalid or uninitialized Zip object

将上面的内容更改为:

$array = explode(".",$_FILES["file"]["name"]);
$extractDir = $array[0];
$fileName = $_FILES["file"]["name"];
$fileExtension = strtolower(end($array));

if(is_dir("unzips/".$extractDir) == false){
   .
   .
   $zip->extractTo("unzips/".$extractDir);
   .
   .
}

这行得通。 希望对您有所帮助:)

zip_close() expects parameter 1 to be resource, object given

错误消息不言自明。

documentation of zip_close() 表示 zip_close() 期望的参数应该是:

A ZIP file previously opened with zip_open().

因为您使用的是 ZipArchive object you have to use its methods to handle it. In particular, ZipArchive::close() is the method used to close a ZipArchive (previously open using ZipArchive::open()

您的代码应如下所示:

$zip = new ZipArchive();
$zip->open("temp/".$_FILES["file"]["name"]);

// Do whatever you want with the content of the archive here (extract files, f.e.)

$zip->close();
