php达成遍历多维数组的方法_php技艺_脚本之家

本文实例讲述了php实现遍历多维数组的方法。分享给大家供大家参考,具体如下:

本文实例讲述了Zend
Framework教程之视图组件Zend_View用法。分享给大家供大家参考,具体如下:

$a=array('fruits'=>array('a'=>'orange','b'=>'grape',c=>'apple'), 'numbers'=>array, 'holes'=>array('first',5=>'second','third') );//第一种:foreach{ if{ foreach($things as $newlist=>$counter){ echo "key:".$newlist."
"."value:".$counter."
"; }}}//第二种:function MulitarraytoSingle{ $temp=array(); if{ foreach ($array as $key=>$value ) { if{ MulitarraytoSingle; } else{ $temp[]=$value; } } }}

Zend_View是Zend Framework的视图组件,MVC中的视图层。
Zend_View也是应用的直接对用户展示的页面。这里介绍一下Zend_View的实现类,以及如何和Controller结合在一起的。

希望本文所述对大家php程序设计有所帮助。

View的实现

Zend_View的实现主要是通过如下目录的类实现:

root@coder-671T-M:/library/Zend# tree | grep View.php│ └── View/├──
View.php

Zend_View和Zend_Controller的整合

主要在Zend_Controller_Action类中,

/** * Initialize View object * * Initializes {@link $view} if not otherwise a Zend_View_Interface. * * If {@link $view} is not otherwise set, instantiates a new Zend_View * object, using the 'views' subdirectory at the same level as the * controller directory for the current module as the base directory. * It uses this to set the following: * - script path = views/scripts/ * - helper path = views/helpers/ * - filter path = views/filters/ * * @return Zend_View_Interface * @throws Zend_Controller_Exception if base view directory does not exist */ public function initView() { if (!$this->getInvokeArg && $this->_helper->hasHelper { return $this->view; } require_once 'Zend/View/Interface.php'; if  && ($this->view instanceof Zend_View_Interface)) { return $this->view; } $request = $this->getRequest(); $module = $request->getModuleName(); $dirs = $this->getFrontController()->getControllerDirectory || !isset { $module = $this->getFrontController->getDefaultModule(); } $baseDir = dirname . DIRECTORY_SEPARATOR . 'views'; if (!file_exists || !is_dir { require_once 'Zend/Controller/Exception.php'; throw new Zend_Controller_Exception('Missing base view directory ; } require_once 'Zend/View.php'; $this->view = new Zend_View(array('basePath' => $baseDir)); return $this->view; } /** * Render a view * * Renders a view. By default, views are found in the view script path as * /.phtml. You may change the script suffix by * resetting {@link $viewSuffix}. You may omit the controller directory * prefix by specifying boolean true for $noController. * * By default, the rendered contents are appended to the response. You may * specify the named body content segment to set by specifying a $name. * * @see Zend_Controller_Response_Abstract::appendBody() * @param string|null $action Defaults to action registered in request object * @param string|null $name Response object named path segment to use; defaults to null * @param bool $noController Defaults to false; i.e. use controller name as subdir in which to search for view script * @return void */ public function render($action = null, $name = null, $noController = false) { if (!$this->getInvokeArg && $this->_helper->hasHelper { return $this->_helper->viewRenderer->render($action, $name, $noController); } $view = $this->initView(); $script = $this->getViewScript($action, $noController); $this->getResponse()->appendBody( $view->render; } /** * Render a given view script * * Similar to {@link render()}, this method renders a view script. Unlike render(), * however, it does not autodetermine the view script via {@link getViewScript()}, * but instead renders the script passed to it. Use this if you know the * exact view script name and path you wish to use, or if using paths that do not * conform to the spec defined with getViewScript(). * * By default, the rendered contents are appended to the response. You may * specify the named body content segment to set by specifying a $name. * * @param string $script * @param string $name * @return void */ public function renderScript($script, $name = null) { if (!$this->getInvokeArg && $this->_helper->hasHelper { return $this->_helper->viewRenderer->renderScript; } $view = $this->initView(); $this->getResponse()->appendBody( $view->render; }

Zend_View.php类

_useViewStream =  ini_get ? false : true; if ($this->_useViewStream) { if (!in_array('zend.view', stream_get_wrappers { require_once 'Zend/View/Stream.php'; stream_wrapper_register('zend.view', 'Zend_View_Stream'); } } if (array_key_exists('useStreamWrapper', $config)) { $this->setUseStreamWrapper($config['useStreamWrapper']); } parent::__construct; } /** * Set flag indicating if stream wrapper should be used if short_open_tag is off * * @param bool $flag * @return Zend_View */ public function setUseStreamWrapper { $this->_useStreamWrapper =  $flag; return $this; } /** * Should the stream wrapper be used if short_open_tag is off? * * @return bool */ public function useStreamWrapper() { return $this->_useStreamWrapper; } /** * Includes the view script in a scope with only public $this variables. * * @param string The view script to execute. */ protected function _run() { if ($this->_useViewStream && $this->useStreamWrapper { include 'zend.view://' . func_get_arg; } else { include func_get_arg; } }}

默认情况会自动通过Controller会通过render方法来实例化Zend_View,
然后rener到对应的视图文件中。当然可以自己实例化Zend_View,然后使用。

action默认指向的文件是和action的名称相同,如果要指定视图文件,可以通过$this->render的相关方法指定.也可以通过addScriptPath和setScriptPath设置视图文件的目录。

$view = new Zend_View();$view->addScriptPath;$view->addScriptPath;// 如果调用 $view->render, Zend_View 将// 首先查找 "/www/app/myviews/example.php", 找不到再找"/www/app/viewscomm/example.php", 如果还找不到,最后查找当前目录下/的"example.php".

Zend_View的常用方法

public function __construct

array, 'encoding' => array;

escape、encoding、basePath、basePathPrefix、scriptPath、helperPath、
helperPathPrefix、filterPath、filterPathPrefix、filterpublic function
getEngine() Return the template engine object

public function init()初始化函数

/*** Given a base path, sets the script, helper, and filter paths relative to it** Assumes a directory structure of:* * basePath/* scripts/* helpers/* filters/* ** @param string $path* @param string $prefix Prefix to use for helper and filter paths* @return Zend_View_Abstract*/public function setBasePath($path, $classPrefix = 'Zend_View')/*** Given a base path, add script, helper, and filter paths relative to it** Assumes a directory structure of:* * basePath/* scripts/* helpers/* filters/* ** @param string $path* @param string $prefix Prefix to use for helper and filter paths* @return Zend_View_Abstract*/public function addBasePath($path, $classPrefix = 'Zend_View')public function addScriptPathAdds to the stack of view script paths in LIFO order.public function setScriptPath Resets the stack of view script paths.public function getScriptPathReturn full path to a view script specified by $namepublic function getScriptPaths()Returns an array of all currently set script pathspublic function addHelperPath($path, $classPrefix = 'Zend_View_Helper_')Adds to the stack of helper paths in LIFO order.public function setHelperPath($path, $classPrefix = 'Zend_View_Helper_')Resets the stack of helper paths.public function getHelperPath Get full path to a helper class file specified by $namepublic function getHelperPaths()Returns an array of all currently set helper pathspublic function getHelper Get a helper by namepublic function getHelpers()Get array of all active helperspublic function getAllPaths() Return associative array of path types => pathspublic function setEscape/*** Assigns variables to the view script via differing strategies.** Zend_View::assign assigns a variable called 'name'* with the corresponding $value.** Zend_View::assign assigns the array keys as variable* names (with the corresponding array values).** @see __set()* @param string|array The assignment strategy to use.* @param mixed  If assigning a named variable, use this* as the value.* @return Zend_View_Abstract Fluent interface* @throws Zend_View_Exception if $spec is neither a string nor an array,* or if an attempt to set a private or protected member is detected*/public function assign

在controller的action可以通过assign传递参数到视图脚本。

$this->view->assign;$this->view->assign;$this->view->assign;

$this->view->roles=$roles;$this->view->a=$a;public function render Processes a view script and returns the output.public function escape:Escapes a value for output in a view script.public function setEncoding Set encoding to use with htmlentities() and htmlspecialchars()public function getEncoding() :Return current escape encoding

视图脚本文件中的常见用法

$this->roles

使用一些常见的助手方法:

$this->baseUrl;$this->paginationControl

在bootstrap初始化view或者controller的init文件中

/** * Initialize the common view helper */protected function _initViewHelper(){ $boot=$this->bootstrap; $view = $boot->getResource; $view->setHelperPath('Sql/View/Helper', 'Sql_View_Helper');}

/** * * @return void */public function listAction(){ $this->view->assign;}
