PHP：无法打开流：没有此类文件或目录

Question

I'm working on implementing Safari Push Notification service for my website. I've been following the tutorial made by Apple which can be found here . And we have to create a package to serve push notifications and Apple provides a companion php file that helps to create the package.

Now I've downloaded the php file and tried running it, but it always throws a warning saying "Failed to open stream: No such file or directory".

Full Log:

PS: I do have a directory named pushPackage.raw that contains a folder called icon.iconset which has a set of 6 png images. So I have no idea why it says "No such file is present".

PHP Companion file

<?php

// This script creates a valid push package.

    http_response_code(500);
    die;
}

header("Content-type: application/zip");
echo file_get_contents($package_path);
die;

Another thing, this php script does create a package at the specified location (D:/Users/Mike/Desktop), but without the contents present in the pushPackage.raw directory.

Please help me resolve this issue. Thank you so much!

You need to run createPushPackage.php from the folder with Safari-Push-Notifications package (in your case D:\\..\\Downloads\\Safari-Push-Notifications-master\\ ) because code copy("pushPackage.raw/$raw_file", "$package_dir/$raw_file"); use relative path to assets files.

Add some explanation for relative paths:

bash$ pwd
/var/www/test # we inside /var/www/
bash$ ls -la # there are 2 files
    -rw-r--r--   1 alexanderpolomodov  wheel   48 Mar  7 15:07 test.php
    -rw-r--r--   1 alexanderpolomodov  wheel   15 Mar  7 15:08 test.txt
# test.php consist from one string
# var_dump(file_get_contents('test.txt'));
bash$ php test.php # run this script
    string(15) "test filepaths"
bash$ cd ..
# when we run this command from another folder we get error
bash$ php test/test.php 
    Warning: file_get_contents(test.txt): failed to open stream: No such file or directory in /private/var/www/test/test.php on line 3
    bool(false)
