An article introducing the settings of PHPYaf

PHPYaf is a simple and efficient PHP framework that allows you to quickly build high-performance web applications. When using PHPYaf, relevant settings must be made to ensure that you can take full advantage of its full functionality. This article will introduce the settings of PHPYaf.

1. PHP version

First of all, you need to ensure that the PHP version meets the requirements. PHPYaf can run in PHP 5.2 and above, but it is recommended to use PHP 7.x version for better performance.

2. Yaf extension

PHPYaf is developed based on the Yaf extension, therefore, you need to ensure that your PHP has the Yaf extension installed. In Linux systems, you can install the extension through the following steps:

wget http://pecl.php.net/get/yaf -3.0.9.tgz

2. Unzip:

tar zxvf yaf-3.0.9.tgz

3. Enter the extension directory:

cd yaf-3.0.9

/usr/local/php/bin/phpize

./configure --with-php-config=/usr/local/php/bin/php-config

make && make install

5. Add the following to php.ini Content:

extension=yaf.so

Note that if you are using PHPYaf under Windows system, you need to download the corresponding DLL file and load it in the PHP configuration file DLL files.

3. Configuration file

PHPYaf uses an ini format configuration file. You need to create a file named "application.ini" in the application root directory to configure various aspects of the application. parameter. Here is a simple example:

[product]

$name = $config->get("name");

Settings:

$config->set("name", "Tom");

$config->toArray();

4. Routing rules

Routing configuration:

/application/configs/routes.ini

[routes]

product/:id/ :name

Route processing:

(1) Create a controller of ProductController.php

class ProductController extends Yaf_Controller_Abstract {

public function indexAction() {
    echo $this->getRequest()->getParam("id") . ", " . $this->getRequest()->getParam("name");
}

}

spl_autoload_register(function ($className) {

$classPath = "/path/to/" . $className . ".php";
if (file_exists($classPath)) {
    require_once $classPath;
}

});

try {

// 你的业务逻辑代码

} catch (Yaf_Exception $e) {

echo $e->getMessage();

}
