Question

我使用此代码从我的文件夹中制作一个zip：

<?php
    // DIRECTORY WE WANT TO BACKUP
    $pathBase = '../';  // Relate Path

    // ZIP FILE NAMING ... This currently is equal to = sitename_www_YYYY_MM_DD_backup.zip 
    $zipPREFIX = "sitename_www";
    $zipDATING = '_' . date('Y_m_d') . '_';
    $zipPOSTFIX = "backup";
    $zipEXTENSION = ".zip";

    // SHOW PHP ERRORS... REMOVE/CHANGE FOR LIVE USE
    ini_set('display_errors',1);
    ini_set('display_startup_errors',1);
    error_reporting(-1);




// ############################################################################################################################
//                                  NO CHANGES NEEDED FROM THIS POINT
// ############################################################################################################################

    // SOME BASE VARIABLES WE MIGHT NEED
    $iBaseLen = strlen($pathBase);
    $iPreLen = strlen($zipPREFIX);
    $iPostLen = strlen($zipPOSTFIX);
    $sFileZip = $pathBase . $zipPREFIX . $zipDATING . $zipPOSTFIX . $zipEXTENSION;
    $oFiles = array();
    $oFiles_Error = array();
    $oFiles_Previous = array();

    // SIMPLE HEADER ;)
    echo '<center><h2>PHP Example: ZipArchive - Mayhem</h2></center>';

    // CHECK IF BACKUP ALREADY DONE
    if (file_exists($sFileZip)) {
        // IF BACKUP EXISTS... SHOW MESSAGE AND THATS IT
        echo "<h3 style='margin-bottom:0px;'>Backup Already Exists</h3><div style='width:800px; border:1px solid #000;'>";
            echo '<b>File Name: </b>',$sFileZip,'<br />';
            echo '<b>File Size: </b>',$sFileZip,'<br />';
        echo "</div>";
        exit; // No point loading our function below ;)
    } else {

        // NO BACKUP FOR TODAY.. SO START IT AND SHOW SCRIPT SETTINGS

当这样完成它压缩文件夹但它在zip的根目录上的每个文件上都有一个斜杠： image

然后我有另一个解压缩zip文件的脚本。

$zip = new ZipArchive;
$res = $zip->open('file.zip');
if ($res === TRUE) {
  $zip->extractTo('/myzips/extract_path/');
  $zip->close();
  echo 'woot!';
} else {
  echo 'doh!';
}

但是当文件和目录以\开头时，它会搞乱解压缩。并且它不会解压缩到目录中，每个文件都会转到unziped文件夹的根目录。 image

如何在zip文件的根目录下删除\？

创建zip是使用\ on file重命名文件
