Question

我有一个PHP脚本来制作带有2个函数的zip：

dirToArray：获取数组中的所有文件/ empty_folders
create_zip：调用dirToArray（）并生成zipArchive

我收到了一个奇怪的警告，实际上是因为我的zip存档没有构建而产生了真正的错误。

警告结果

警告：ZipArchive :: close（）：读取错误：第x行路径/ to / file.php中的文件描述符错误

有人可以解释一下是什么意思：“文件描述符不好”？

这是代码：

dirToArray

/* to copy all file/folder names from a directory into an array*/
function dirToArray($dir_path) {
    $result = array();
    $path = realpath($dir_path);
    $objects = new \RecursiveIteratorIterator(new \RecursiveDirectoryIterator($path), \RecursiveIteratorIterator::SELF_FIRST);
    foreach($objects as $name => $object) {
        if( $object->getFilename() !== "." && $object->getFilename() !== "..") {
            $result[] = $object;
        }
    }
    return $result;
}

create_zip

/* creates a compressed zip file */
function create_zip($productPath = '', $dirName = '', $overwrite = false) {
    $fullProductPath = $productPath.$dirName;
    $a_filesFolders = dirToArray( $fullProductPath );
    var_dump($a_filesFolders);
    //if the zip file already exists and overwrite is false, return false
    $zip = new \ZipArchive();
    $zipProductPath =  $fullProductPath.'.zip';
    if($zip->open( $zipProductPath ) && !$overwrite){
        $GLOBALS["errors"][] = "The directory {$zipProductPath} already exists and cannot be removed.";
    }

    //if files were passed in...
    if(is_array($a_filesFolders) && count($a_filesFolders)){
        $opened = $zip->open( $zipProductPath, \ZipArchive::CREATE | \ZipArchive::OVERWRITE );
        if( $opened !== true ){
            $GLOBALS["errors"][] = "Impossible to open {$zipProductPath} to edit it.";
        }

        //cycle through each file
        foreach($a_filesFolders as $object) {
            //make sure the file exists
            $fileName = $object -> getFilename();
            $pathName = $object -> getPathname();
            if(file_exists($pathName)) {
                $pos = strpos($zipProductPath , "/tmp/") + 5;
                $fileDestination = substr($pathName, $pos);
                echo $pathName.'<br/>';
                echo $fileDestination.'<br/>';
                $zip->addFile($pathName,$fileDestination);
            }
            else if(is_dir( $pathName )){
                $pos = strpos($zipProductPath , "/tmp/") + 5;
                $fileDestination = substr($pathName, $pos);
                $zip->addEmptyDir($fileDestination);
            }else{
                $GLOBALS["errors"][] = "the file ".$fileName." does not exist !";
            }
        }

        //close the zip -- done!
        $zip->close();
        //check to make sure the file exists
        return file_exists($zipProductPath);
    }else{
        return false;
    }
}

我发现了问题...我对file_exists（）函数感到困惑，该函数检测目录是否存在...所以脚本将文件夹添加为文件并制作了错误。

create_zip（已修补）

/* creates a compressed zip file */
function create_zip($productPath = '', $dirName = '', $overwrite = false) {
    $fullProductPath = $productPath.$dirName;
    $a_filesFolders = dirToArray( $fullProductPath );
    var_dump($a_filesFolders);
    //if the zip file already exists and overwrite is false, return false
    $zip = new \ZipArchive();
    $zipProductPath =  $fullProductPath.'.zip';

    if($zip->open( $zipProductPath ) && !$overwrite){
        $GLOBALS["errors"][] = "The directory {$zipProductPath} already exists and cannot be removed.";
        return false;
    }
    //if files were passed in...
    if(is_array($a_filesFolders) && count($a_filesFolders)){
         $opened = $zip->open( $zipProductPath, \ZipArchive::CREATE | \ZipArchive::OVERWRITE );
        if( $opened !== true ){
            $GLOBALS["errors"][] = "Impossible to open {$zipProductPath} to edit it.";
            return false;
        }else{
            //cycle through each file
            foreach($a_filesFolders as $object) {
                //make sure the file exists
                $fileName = $object -> getFilename();
                $pathName = $object -> getPathname();
                if(is_dir( $pathName )){ /*<-- I put on first position*/
                    $pos = strpos($zipProductPath , "/tmp/") + 5;
                    $fileDestination = substr($pathName, $pos);
                    $zip->addEmptyDir($fileDestination);
                }else if(file_exists($pathName)) {
                    $pos = strpos($zipProductPath , "/tmp/") + 5;
                    $fileDestination = substr($pathName, $pos);
                    $zip->addFile($pathName,$fileDestination);
                }
                else{
                    $GLOBALS["errors"][] = "the file ".$fileName." does not exist !";
                }
            }

            //close the zip -- done!
            $zip->close();
            //check to make sure the file exists
            return file_exists($zipProductPath);
        }
    }else{
        return false;
    }
}

在PHP中，这意味着什么：警告：ZipArchive :: close（）：读错误：（...）中的文件描述符错误？
