从框架代码看zendframework支持配置项

 

配置项生效的主要方法：Zend_Application的setOptions()方法

代码片段如下：

        if (!empty($options['phpsettings'])) {
            $this->setPhpSettings($options['phpsettings']);
        }

        if (!empty($options['includepaths'])) {
            $this->setIncludePaths($options['includepaths']);
        }

        if (!empty($options['autoloadernamespaces'])) {
            $this->setAutoloaderNamespaces($options['autoloadernamespaces']);
        }

        if (!empty($options['autoloaderzfpath'])) {
            $autoloader = $this->getAutoloader();
            if (method_exists($autoloader, 'setZfPath')) {
                $zfPath    = $options['autoloaderzfpath'];
                $zfVersion = !empty($options['autoloaderzfversion'])
                           ? $options['autoloaderzfversion']
                           : 'latest';
                $autoloader->setZfPath($zfPath, $zfVersion);
            }
        }

        if (!empty($options['bootstrap'])) {
            $bootstrap = $options['bootstrap'];

            if (is_string($bootstrap)) {
                $this->setBootstrap($bootstrap);
            } elseif (is_array($bootstrap)) {
                if (empty($bootstrap['path'])) {
                    throw new Zend_Application_Exception('No bootstrap path provided');
                }

                $path  = $bootstrap['path'];
                $class = null;

                if (!empty($bootstrap['class'])) {
                    $class = $bootstrap['class'];
                }

                $this->setBootstrap($path, $class);
            } else {
                throw new Zend_Application_Exception('Invalid bootstrap information provided');
            }
        }

setPhpSettings()方法

    public function setPhpSettings(array $settings, $prefix = '')
    {
        foreach ($settings as $key => $value) {
            $key = empty($prefix) ? $key : $prefix . $key;
            if (is_scalar($value)) {
                ini_set($key, $value);
            } elseif (is_array($value)) {
                $this->setPhpSettings($value, $key . '.');
            }
        }

        return $this;
    }

 假如我们想在config.ini 配置文件中打开php错误显示，那么可以配置

phpSettings.display_errors  = 1

setIncludePaths方法：

    public function setIncludePaths(array $paths)
    {
        $path = implode(PATH_SEPARATOR, $paths);
        set_include_path($path . PATH_SEPARATOR . get_include_path());
        return $this;
    }

如果想将项目根目录下的foo/bar 目录加入进来。config.ini配置文件可以这样写

includepaths[]=APPLICATION_PATH "/../foo/bar"

 打印下看看是否已加入

var_dump(get_include_path());exit;

setAutoloaderNamespaces()

    public function setAutoloaderNamespaces(array $namespaces)
    {
        $autoloader = $this->getAutoloader();

        foreach ($namespaces as $namespace) {
            $autoloader->registerNamespace($namespace);
        }

        return $this;
    }

config.ini配置文件中可以这样写 

autoloadernamespaces[]="Foo_Bar"
