A palavra stream significa corrente. Em geral, qualquer conexão de rede é uma stream, e existem vários tipos de protocolos para streams. Esses protocolos definem como os dados fluem na corrente.
No PHP, vários protocolos são suportados de forma transparente:
<?php
| <?php | |
| $a = 10; | |
| if ($a > 5) { | |
| $b = 5; | |
| } else { | |
| $b = 10; | |
| } |
| <?php | |
| // PHP Self Stats | |
| /* | |
| * get_loaded_extensions() returns all the extension names | |
| * currently loaded. | |
| * | |
| * Using array_intersect(), we can get only the extensions | |
| * we want from those which are really available. |
I was asked how I deal with validation / create and update validation rulesets. Well here is one method I have used. Don't be afraid to build on top of what the framework has already given you. In my projects I use a base class for almost anything. You never know when you want your classes to inherit some common functionality. My BaseValidator actually has some pretty useful methods and properties in it.
<?php
namespace FooProject\Internal\Validators;
use FooProject\Internal\Sanitizers\BaseSanitizer;

| require 'gosu' # gem install gosu --no-document | |
| include Gosu | |
| $dimension, $splits = 200, 20 | |
| $size = $dimension.to_f / $splits.to_f | |
| class Worm | |
| attr_writer :dir | |
| def initialize() reset end |
| <?php | |
| /** | |
| * Handle file uploading and add attachment. | |
| * | |
| * @return array Uploaded file's details on success, error message on failure | |
| */ | |
| function wp_import_handle_upload() { | |
| if ( !isset($_FILES['filefield_name']) ) { | |
| $file['error'] = __( 'File is empty. Please upload something more substantial. This error could also be caused by uploads being disabled in your php.ini or by post_max_size being defined as smaller than upload_max_filesize in php.ini.' ); | |
| return $file; |
