note 116203 added to language.namespaces.definitionmultiple

When working with multiple namespaces in the same file pay attention for the use of __autoload() : <?php // vendor/Namespaces/Test.php namespace Namespaces\One; class Test { public function __construct() { echo __NAMESPACE__, PHP_EOL; } } namespace Namespaces\Two; class Test { public function __construct() { echo __NAMESPACE__, PHP_EOL; } } ?> <?php // index.php error_reporting(E_ALL); ini_set('display_errors', true); function __autoload($class) { $filename = str_replace('\\', '/', $class) . '.php'; require_once $filename; } // Will not work since there are no "One" and "Two" directories! new \Namespaces\One\Test(); new \Namespaces\Two\Test(); // Works require_once 'vendor/Namespaces/Test.php'; new \Namespaces\One\Test(); new \Namespaces\Two\Test(); ?> ---- Server IP: 72.52.91.14 Probable Submitter: 177.32.116.168 ---- Manual Page -- http://php.net/manual/en/language.namespaces.definitionmultiple.php Edit -- https://master.php.net/note/edit/116203 Del: integrated -- https://master.php.net/note/delete/116203/integrated Del: useless -- https://master.php.net/note/delete/116203/useless Del: bad code -- https://master.php.net/note/delete/116203/bad+code Del: spam -- https://master.php.net/note/delete/116203/spam Del: non-english -- https://master.php.net/note/delete/116203/non-english Del: in docs -- https://master.php.net/note/delete/116203/in+docs Del: other reasons-- https://master.php.net/note/delete/116203 Reject -- https://master.php.net/note/reject/116203 Search -- https://master.php.net/manage/user-notes.php
