PHP: Failed to open stream: No such file or directory

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

// Convenience function that returns an array of raw files needed to construct the package.
function raw_files() {
    return array(

    }
    file_put_contents("$package_dir/manifest.json", json_encode((object)$manifest_data));
}

// Creates a signature of the manifest using the push notification certificate.
function create_signature($package_dir, $cert_path, $cert_password) {
    // Load the push notification certificate
    $pkcs12 = file_get_contents($cert_path);
    $certs = array();
    if(!openssl_pkcs12_read($pkcs12, $certs, $cert_password)) {

// MAIN
$package_path = create_push_package();
if (empty($package_path)) {
    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!

Make sure your .PNG files are in the specified path and have proper permissions to be readable by PHP. The warnings seem to imply that they're not there. — apokryfos, Mar 07 '16 at 10:59
The PNG files are there and proper permissions are there. I have checked it in both Windows and Mac, every time this warning comes. — Sivaprasanna Sethuraman, Mar 07 '16 at 12:01
You're using relative paths to the PNGs . Can you do an `echo getcwd()` to make sure you're currently in the correct directory? — apokryfos, Mar 07 '16 at 12:06

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)

Actually, it is there only. The createPushPackage.php file is in the same directory where pushPackage.raw resides. – Sivaprasanna Sethuraman Mar 07 '16 at 11:57

You need to run your php script when you are inside Safari-Push-Notifications directory. Relative paths related to the your current point inside filesystem. – alexander.polomodov Mar 07 '16 at 12:14
