从zip目录中删除文件

Question

I have a zip file called project.zip with the following structure:

project.zip  
  \project  
    \file.pdf  

I need to delete file.pdf. I tried the following code but I'm getting an error.
Thanks

$zip = new ZipArchive(); 

    $zip_name = 'path\to\project.zip';

    $zip->open( $zip_name );

    $zip->deleteName( 'project\file.pdf' ); 

    $zip->close();

I Also tried with a leading backslash but with no success,

$zip->deleteName( 'prject\file.pdf' );

Answer 1

use forward slashes :

$zip->deleteName( 'project/file.pdf' );
