前段时间写了个关于手机应用的api,一直是用的query_string这种地址,而且还是根据一个act参数来区分所有的动作,这种让开发人员看起来比较费眼。本来想改写为“?c=controller&m=method&type=3&id=1” 这种形式,利用m参数来载入文件并进行实例化,后来看了sina weibo api 是对地址进行了路由。也决定跟风对地址路由。本来CI框架自己自带路由效果,但是因为考虑是写api,想写的比较纯粹一点。
支持默认控制器(index)和方法(index):
index.php
index.php/controller
index.php/controller/method
index.php/controller/method/prarme1/value1
index.php/controller/method/param1/value1/param2/value2.....
具体类如下:
$APP_PATH= str_replace($_SERVER['DOCUMENT_ROOT'], '', __FILE__);
$SE_STRING=str_replace($APP_PATH, '', $_SERVER['REQUEST_URI']); //计算出index.php后面的字段 index.php/controller/methon/id/3
$SE_STRING=trim($SE_STRING,'/');
//echo $SE_STRING.'
';
//这里需要对$SE_STRING进行过滤处理。
$ary_url=array(
'controller'=>'index',
'method'=>'index',
'pramers'=>array()
);
//var_dump($ary_url);
$ary_se=explode('/', $SE_STRING);
$se_count=count($ary_se);
//路由控制
if($se_count==1 and $ary_se[0]!='' ){
$ary_url['controller']=$ary_se[0];
}else if($se_count>1){//计算后面的参数,key-value
$ary_url['controller']=$ary_se[0];
$ary_url['method']=$ary_se[1];
if($se_count>2 and $se_count%2!=0){ //没有形成key-value形式
die('参数错误');
}else{
for($i=2;$i $ary_kv_hash=array(strtolower($ary_se[$i])=>$ary_se[$i+1]);
$ary_url[pramers]=array_merge($ary_url[pramers],$ary_kv_hash);
}
}
}
$module_name=$ary_url['controller'];
$module_file=MODULE_DIR.$module_name.'.class.php';
//echo $module_file;
$method_name=$ary_url['method'];
if(file_exists($module_file)){
include($module_file);
$obj_module=new $module_name(); //实例化模块m
if(!method_exists($obj_module, $method_name)){
die('方法不存在');
}else{
if(is_callable(array($obj_module, $method_name))){ //该方法是否能被调用
//var_dump($ary_url[pramers]);
$get_return=$obj_module->$method_name($ary_url[pramers]); //执行a方法,并把key-value参数的数组传过去
if(!is_null($get_return)){ //返回值不为空
var_dump($get_return);
}
}else{
die('该方法不能被调用');
}
}
}
else
{
die('模块文件不存在');
}

What’s still popular is the ease of use, flexibility and a strong ecosystem. 1) Ease of use and simple syntax make it the first choice for beginners. 2) Closely integrated with web development, excellent interaction with HTTP requests and database. 3) The huge ecosystem provides a wealth of tools and libraries. 4) Active community and open source nature adapts them to new needs and technology trends.

PHP and Python are both high-level programming languages that are widely used in web development, data processing and automation tasks. 1.PHP is often used to build dynamic websites and content management systems, while Python is often used to build web frameworks and data science. 2.PHP uses echo to output content, Python uses print. 3. Both support object-oriented programming, but the syntax and keywords are different. 4. PHP supports weak type conversion, while Python is more stringent. 5. PHP performance optimization includes using OPcache and asynchronous programming, while Python uses cProfile and asynchronous programming.

PHP is mainly procedural programming, but also supports object-oriented programming (OOP); Python supports a variety of paradigms, including OOP, functional and procedural programming. PHP is suitable for web development, and Python is suitable for a variety of applications such as data analysis and machine learning.

PHP originated in 1994 and was developed by RasmusLerdorf. It was originally used to track website visitors and gradually evolved into a server-side scripting language and was widely used in web development. Python was developed by Guidovan Rossum in the late 1980s and was first released in 1991. It emphasizes code readability and simplicity, and is suitable for scientific computing, data analysis and other fields.

PHP is suitable for web development and rapid prototyping, and Python is suitable for data science and machine learning. 1.PHP is used for dynamic web development, with simple syntax and suitable for rapid development. 2. Python has concise syntax, is suitable for multiple fields, and has a strong library ecosystem.

PHP remains important in the modernization process because it supports a large number of websites and applications and adapts to development needs through frameworks. 1.PHP7 improves performance and introduces new features. 2. Modern frameworks such as Laravel, Symfony and CodeIgniter simplify development and improve code quality. 3. Performance optimization and best practices further improve application efficiency.

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.

mPDF
mPDF is a PHP library that can generate PDF files from UTF-8 encoded HTML. The original author, Ian Back, wrote mPDF to output PDF files "on the fly" from his website and handle different languages. It is slower than original scripts like HTML2FPDF and produces larger files when using Unicode fonts, but supports CSS styles etc. and has a lot of enhancements. Supports almost all languages, including RTL (Arabic and Hebrew) and CJK (Chinese, Japanese and Korean). Supports nested block-level elements (such as P, DIV),
