autoloader

问题 I am creating a PHP project and want to implement PSR-4 autoloading. I don't know which files I need to create in the vendor directory to implement autoloading for class files. 回答1: If you are using composer , you do not create the autoloader but let composer do its job and create it for you. The only thing you need to do is create the appropriate configuration on composer.json and execute composer dump-autoload . E.g.: { "autoload": { "psr-4": {"App\\": "src/"} } } By doing the above, if you

问题 I want to use pure firebase/php-jwt library in my code. Firstly, I go to /var/www/html/ and like the official library page is suggesting, I do this composer require firebase/php-jwt After I run this command, I see that a new vendor folder is created inside /var/www/html/ with a lot of files and subfolders. I then create my token.php file right in /var/www/html/ with contents similar to that from the official page: <?php use \Firebase\JWT\JWT; $key = "example_key"; $token = array( "iss" =>

问题 does someone knows how to use the "new" Zend Autoloader to Load Models ?

问题 I've been creating an application that requires buttons to make an ajax call to a controller that uses autoloaded models. I was under the impression that variables in an autoloaded model would retain their values after an Ajax call, but for some reason the entire model (including their variables) have lost their new values. Am I misunderstanding the way the autoload function works, or does it have something to do with me using Ajax? Code for reference below. Autoload: $autoload['model'] =

问题 I'm using composer to generate autoloader: "autoload": { "psr-4": { "SomeNamespace\\": "src/SomeDir" } } I need to create instances of all classes that implement specific interface. It's fairly easy when not using autoloader, however get_declared_classes() is not playing well with autoloaders. It will list a class only after it was instantiated with autoloader. 回答1: If you don't keep track of which classes exist, autoloading won't help you. But the situation would be pretty much the same if

问题 I'm working on a project with Zend Framework 1.11, Doctrine 2, some Symfony 2 componenents and others tools & libraries. I'm trying to optimize performance using Xdebug & Webgrind. I've already found some bottlenecks like parsing Ini config, etc.. and cached that. Now, I just realize that the autoloading is the most costly part of my application: Opl\Autoloader\ApcLoader->loadClass 274 31.36 43.86 Zend_Loader_PluginLoader->load 150 4.80 12.29 Zend_Loader_Autoloader->getClassAutoloaders 278 1
