Install

1. Identify the public web folder for your website. It's probably something like public_html.

2. Create a folder called codebases. Do not put it inside public_html.

   mkdir /path/to/codebases

3. Create a folder called storage. Do not put it inside public_html. You need to set the permissions so your web server can write to this folder.

   mkdir /path/to/storage
   chmod 777 /path/to/storage

4. Clone the SkyPHP codebase into your codebases folder.

   cd /path/to/codebases
   git clone --recursive -b 3.0 git://github.com/SkyPHP/skyphp.git

5. Create a folder for your new project in codebases.

   mkdir /path/to/codebases/my-project
   mkdir /path/to/codebases/my-project/lib
   mkdir /path/to/codebases/my-project/pages
   mkdir /path/to/codebases/my-project/templates

6. Put .htaccess and index.php into your public web folder:

• /path/to/public_html/.htaccess -- copy this file from skyphp/, or better yet create a symbolic link:

  ln -s /path/to/codebases/skyphp/.htaccess /path/to/public_html/

• /path/to/public_html/index.php

  <?php
  // index.php
  // Powered by SkyPHP (github.com/SkyPHP)
  
  #$down_for_maintenance = true;
  
  $my_project_path = '/path/to/codebases/my-project/';
  $skyphp_codebase_path = '/path/to/codebases/skyphp/';
  
  $codebase_path_arr = [
      $my_project_path,
      $skyphp_codebase_path
  ];
  
  // make sure this folder is writable
  $skyphp_storage_path = "/path/to/storage/";
  
  include $skyphp_codebase_path . 'sky.php';

Now open your website in your browser and you should see the 'Welcome to SkyPHP' page.

Sky\Page

Sample page

/pages/test/test.php --> example.com/test

<?php

$this->title = 'Hello World';

// The js and css files for this page are attached automatically by the html5 template
// $this->js[] = '/pages/test/test.js';
// $this->css[] = '/pages/test/test.css';

$this->js[] = '/lib/js/some-other-library.js';

$this->head[] = '<meta property="example" content="you can add html to your head">';

$this->template('html5', 'top');
?>
    <h1>My Hello World Page</h1>
<?php
    // ($this) is the Page object
    d($this); // see some info about your Page

$this->template('html5', 'bottom');

Sky\Model

Saving data objects to the database

<?php

use \My\Model\artist;

$artist = new artist([                  // Create the object...
    'name' => 'Anthrax'
]);                                     // but don't save to the database yet.

if ($artist->_errors) {                 // Validation errors are generated in real-time.
    d($artist->_errors);                // Dump _errors array in a nice html format.
}

$artist->name = 'Slayer';               // Set the artist's name.
$artist->save();                        // Save the object to the database.

$artist->set([                          // Change multiple fields.
    'name' => 'Slayer',                 // *'name' is not saved in this case because only
    'state' => 'CA',                    // modified fields are saved.
    'albums' => [                       // You can easily save nested objects.
        [
            'name' => 'Diabolus in Musica',
            'year' => 1998
        ]
    ]
])->save();

$artist->update([                       // Shorthand for updating fields in the database.
    'name' => 'Slanthrax'
]);

$artist = artist::insert([              // shorthand for inserting new objects to the db.
    'name' => 'Anthrax',
    'state' => 'NY'
]);
echo $artist->id; // 5                  // Get the newly created artist_id.

Getting data objects from the database

<?php

$aritst_id = 5;
$artist = new artist($artist_id);       // Get artist from database by primary key.
$artist = artist::get($artist_id);      // This is the same as above.
echo $artist->name; // Anthrax

$artist = artist::getOne([              // Get one artist using some criteria
    'where' => "name = 'Slayer'"        // ('where' can be a string or array)
])->update([                            // and change their city.
    'city' => 'Huntington Park'
]);

$artists = artist::getMany([            // Get 100 "the" bands from Brooklyn.
    'where' => [
        "name ilike 'The %'",
        "city = 'Brooklyn'",
        "state = 'NY'"
    ],
    'limit' => 100,
    'order by' => 'name asc'
]);
foreach ($artists as $artist) {         // Display each artist and number of albums.
    $qty = count($artist->albums);
    echo "{$artist->name} have {$qty} albums.<br />";
}

$number_of_bands = artist::getCount([   // Get a count of all artists in Brooklyn.
    'where' => "city = 'Brooklyn' and state = 'NY'"
]);

$artist_ids = artist::getList([         // Get an array of every artist.id in NY.
    'where' => "state = 'NY'"
]);
