php function judgment based on Example regular Browser of expression language default

   PHP函数实例,基于正则表达式来判断浏览器的默认语言,其实php判断浏览器语言使用超级全局变量_SERVER["HTTP_ACCEPT_LANGUAGE"] 就可以获得了,然后再根据HTTP请求的Accept-Language: 头信息用正则匹配,最终判断出语言类型。

  PHP判断浏览器实例函数:

  01

  02$lang=substr($_SERVER['HTTP_ACCEPT_LANGUAGE'],0,4);

  03//只取前4位,可判断最优先的语言

  04if (preg_match("/zh-c/i", $lang))

  05 echo "简体中文";

  06else if (preg_match("/zh/i", $lang))

  07 echo "繁體中文";

  08else if (preg_match("/en/i", $lang))

  09 echo "English";

  10else if (preg_match("/fr/i", $lang))

  11 echo "French";

  12else if (preg_match("/de/i", $lang))

  13 echo "German";

  14else if (preg_match("/jp/i", $lang))

  15 echo "Japanese";

  16else if (preg_match("/ko/i", $lang))

  17 echo "Korean";

  18else if (preg_match("/es/i", $lang))

  19 echo "Spanish";

  20else if (preg_match("/sv/i", $lang))

  21 echo "Swedish";

  22else

  23 echo $_SERVER["HTTP_ACCEPT_LANGUAGE"];

  24?>

  在使用时只需调用函数名即可,本函数会自动返回检测结果。

Is Debian Strings compatible with multiple browsers Is Debian Strings compatible with multiple browsers Apr 02, 2025 am 08:30 AM

"DebianStrings" is not a standard term, and its specific meaning is still unclear. This article cannot directly comment on its browser compatibility. However, if "DebianStrings" refers to a web application running on a Debian system, its browser compatibility depends on the technical architecture of the application itself. Most modern web applications are committed to cross-browser compatibility. This relies on following web standards and using well-compatible front-end technologies (such as HTML, CSS, JavaScript) and back-end technologies (such as PHP, Python, Node.js, etc.). To ensure that the application is compatible with multiple browsers, developers often need to conduct cross-browser testing and use responsiveness

Explain JSON Web Tokens (JWT) and their use case in PHP APIs. Explain JSON Web Tokens (JWT) and their use case in PHP APIs. Apr 05, 2025 am 12:04 AM

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,
