php常用的url处理函数总结,phpurl函数
本文实例总结了几种在php中url编码解析函数,如parse_url、rawurldecode、rawurlencode、urldecode、urlencode.分享给大家供大家参考。具体用法如下:
下面来看介绍与实例:parse_url($str url);
把url转换成数组:print_r(parse_url("www.jb51.net")); 解析url并输出返回数组,url 专用格式字符串还原成普通字符串.
语法:string rawurldecode(string str);
返回值:字符串
函数种类:编码处理
内容说明:本函数将字符串解码,从 url 的字符串专用格式解成普通字符串,详细的编码解码信息及规格文件可以参考 rfc 1738,代码如下:
复制代码 代码如下:
echo rawurldecode('foo%20bar%40baz'); //输出foo bar@baz
string rawurlencode ( string str )
返回字符串,此字符串中除了 -_. 之外的所有非字母数字字符都将被替换成百分号(%)后跟两位十六进制数,这是在 rfc 1738 中描述的编码,是为了保护原义字符以免其被解释为特殊的 url 定界符,同时保护 url 格式以免其被传输媒体,像一些邮件系统,使用字符转换时弄乱,例如,如果你想在 ftp 的 url 中包含密码:
复制代码 代码如下:
$str="http://www.bkjia.com"; //定义字符串
$result=rawurlencode($str); //对指定字符串编码
echo $result;
/*
urldecode()
url解码
*/ //输出结果
$str="http%3a%2f%2fwww.jb51.net";
$result=urldecode($str);
echo $result;
/*
urlencode()
url编码
*/
$str="http://www.bkjia.com"; //定义字符串
$result=urlencode($str); //对指定字符串编码
echo $result; //输出结果
希望本文所述对大家的PHP程序设计有所帮助。

This tutorial demonstrates how to efficiently process XML documents using PHP. XML (eXtensible Markup Language) is a versatile text-based markup language designed for both human readability and machine parsing. It's commonly used for data storage an

JWT is an open standard based on JSON, used to securely transmit information between parties, mainly for identity authentication and information exchange. 1. JWT consists of three parts: Header, Payload and Signature. 2. The working principle of JWT includes three steps: generating JWT, verifying JWT and parsing Payload. 3. When using JWT for authentication in PHP, JWT can be generated and verified, and user role and permission information can be included in advanced usage. 4. Common errors include signature verification failure, token expiration, and payload oversized. Debugging skills include using debugging tools and logging. 5. Performance optimization and best practices include using appropriate signature algorithms, setting validity periods reasonably,

Static binding (static::) implements late static binding (LSB) in PHP, allowing calling classes to be referenced in static contexts rather than defining classes. 1) The parsing process is performed at runtime, 2) Look up the call class in the inheritance relationship, 3) It may bring performance overhead.

A string is a sequence of characters, including letters, numbers, and symbols. This tutorial will learn how to calculate the number of vowels in a given string in PHP using different methods. The vowels in English are a, e, i, o, u, and they can be uppercase or lowercase. What is a vowel? Vowels are alphabetic characters that represent a specific pronunciation. There are five vowels in English, including uppercase and lowercase: a, e, i, o, u Example 1 Input: String = "Tutorialspoint" Output: 6 explain The vowels in the string "Tutorialspoint" are u, o, i, a, o, i. There are 6 yuan in total

What are the magic methods of PHP? PHP's magic methods include: 1.\_\_construct, used to initialize objects; 2.\_\_destruct, used to clean up resources; 3.\_\_call, handle non-existent method calls; 4.\_\_get, implement dynamic attribute access; 5.\_\_set, implement dynamic attribute settings. These methods are automatically called in certain situations, improving code flexibility and efficiency.

PHP and Python each have their own advantages, and choose according to project requirements. 1.PHP is suitable for web development, especially for rapid development and maintenance of websites. 2. Python is suitable for data science, machine learning and artificial intelligence, with concise syntax and suitable for beginners.

PHP is widely used in e-commerce, content management systems and API development. 1) E-commerce: used for shopping cart function and payment processing. 2) Content management system: used for dynamic content generation and user management. 3) API development: used for RESTful API development and API security. Through performance optimization and best practices, the efficiency and maintainability of PHP applications are improved.

PHP is a scripting language widely used on the server side, especially suitable for web development. 1.PHP can embed HTML, process HTTP requests and responses, and supports a variety of databases. 2.PHP is used to generate dynamic web content, process form data, access databases, etc., with strong community support and open source resources. 3. PHP is an interpreted language, and the execution process includes lexical analysis, grammatical analysis, compilation and execution. 4.PHP can be combined with MySQL for advanced applications such as user registration systems. 5. When debugging PHP, you can use functions such as error_reporting() and var_dump(). 6. Optimize PHP code to use caching mechanisms, optimize database queries and use built-in functions. 7
