HomeBackend DevelopmentPHP TutorialThinkPHP V2.2说明文档没有说明的那些事实例小结_PHP

本文实例讲述了ThinkPHP V2.2说明文档没有说明的那些事。分享给大家供大家参考。具体分析如下:

以下是总结一下说明文档没有提及和详细说明的内容:(日后不断更新)

1. 在配置文件中设置了APP_DEBUG为true,进入debug模式的时候,页面默认是不会显示trace信息信息的。

解决方法:'SHOW_PAGE_TRACE'=>true 加上这个就可以了。

2.action 内的success 方法只需要存入两个参数 success($message,$ajax=false),调用的页面是没写也会显示。

解决方法:要在配置文件中加上:
'TMPL_ACTION_SUCCESS'     => 'Public:success'(错误跳转:'TMPL_ACTION_ERROR'     => 'Public:success')

其实2.2版本中默认设置是这样的:

'TMPL_ACTION_ERROR'     => THINK_PATH.'/Tpl/dispatch_jump.html'。

3.用普通标签load模板引擎直接无视。

解决方法:无(还没找到原因)

4.__ROOT__在模板输入只会是空字符,在页面跳转后就不能用__ROOT__地址回到首页了。

解决方法:自己去修改__ROOT__,又或者在所有页面中加上, 如:

5.有些服务器上ThinkPHP框架会出现以下问题:

无法加载模块,这情况在是否有设置.htaccess文件无关。

问题在于ThinkPHP\Lib\Think\Util\Dispatcher.class.php中的getPathInfo方法中

此方法是重新负值于$_SERVER['PATH_INFO'],问题就来了

$_SERVER['PATH_INFO']
$_SERVER['ORIG_PATH_INFO']
$_SERVER['REDIRECT_PATH_INFO']
$_SERVER["REDIRECT_URL"]

以上的系统变量不一定有,这个是全蛋疼的事,所以getPathInfo会一路判断有哪个就要怎么处理什么的。

出问题的地方在于判断有$_SERVER["REDIRECT_URL"]之后的操作,原码:

$path = $_SERVER["REDIRECT_URI"];
if(empty($_SERVER['QUERY_STRING']) || $_SERVER['QUERY_STRING'] == $_SERVER["REDIRECT_QUERY_STRING"]) {
$parsedUrl = parse_url($_SERVER["REQUEST_URL"]);
if(!empty($parsedUrl['query'])) {
$_SERVER['QUERY_STRING'] = $parsedUrl['query'];
parse_str($parsedUrl['query'], $GET);
$_GET = array_merge($_GET, $GET);
reset($_GET);
}else {
unset($_SERVER['QUERY_STRING']);
}
reset($_SERVER);
}

标成红色的就是出错的原因,改成REQUEST_URI就会正常的了。

*注:$_SERVER["REQUEST_URI"] 获取http://blog.lpreterite.com后面的值,包括/

希望本文所述对大家基于ThinkPHP的php程序设计有所帮助。

How does PHP type hinting work, including scalar types, return types, union types, and nullable types?How does PHP type hinting work, including scalar types, return types, union types, and nullable types?Apr 17, 2025 am 12:25 AM

PHP type prompts to improve code quality and readability. 1) Scalar type tips: Since PHP7.0, basic data types are allowed to be specified in function parameters, such as int, float, etc. 2) Return type prompt: Ensure the consistency of the function return value type. 3) Union type prompt: Since PHP8.0, multiple types are allowed to be specified in function parameters or return values. 4) Nullable type prompt: Allows to include null values ​​and handle functions that may return null values.

How does PHP handle object cloning (clone keyword) and the __clone magic method?How does PHP handle object cloning (clone keyword) and the __clone magic method?Apr 17, 2025 am 12:24 AM

In PHP, use the clone keyword to create a copy of the object and customize the cloning behavior through the \_\_clone magic method. 1. Use the clone keyword to make a shallow copy, cloning the object's properties but not the object's properties. 2. The \_\_clone method can deeply copy nested objects to avoid shallow copying problems. 3. Pay attention to avoid circular references and performance problems in cloning, and optimize cloning operations to improve efficiency.
