PHP html_entity_decode() 实例
虽然使用PHP htmlentities() 只能对HTML标签字符串进行HTML 实体化,但是您可以使用PHP html_entity_decode() 对所有HTML 实体化的字符进行转换成字符。
<?<span php </span><span function</span> showCode(<span $s</span>){<span return</span> <span str_replace</span>('&', '&', <span $s</span><span );} </span><span //</span><span 由于转成HTML实体后,输出依旧是原字符,所以这里对 & 替换成 & 可以输出源代码格式,如果不用这个替换,您可以通过查看输出的 $html 源代码,能够看到一样的结果。</span> <span $weigeti</span> = '-->"E.V-Get.com"<--'<span ; </span><span $html</span> = <span htmlentities</span>(<span $weigeti</span>,<span ENT_QUOTES); </span><span echo</span> showCode(<span $html</span><span ); </span><span //</span><span 输出【-->"E.V-Get.com"<--】</span> <span $entity</span> = <span html_entity_decode</span>(<span $html</span><span ); </span><span echo</span> showCode(<span $entity</span><span ); </span><span //</span><span 输出【-->"E.V-Get.com"<--】</span> <span $entity_noquotes</span>=<span html_entity_decode</span>(<span $html</span>,<span ENT_NOQUOTES); </span><span echo</span> showCode(<span $entity_noquotes</span><span ); </span><span //</span><span 输出【-->"E.V-Get.com"<--】</span> ?>

Session in PHP is a mechanism for saving user data on the server side to maintain state between multiple requests. Specifically, 1) the session is started by the session_start() function, and data is stored and read through the $_SESSION super global array; 2) the session data is stored in the server's temporary files by default, but can be optimized through database or memory storage; 3) the session can be used to realize user login status tracking and shopping cart management functions; 4) Pay attention to the secure transmission and performance optimization of the session to ensure the security and efficiency of the application.

Absolute session timeout starts at the time of session creation, while an idle session timeout starts at the time of user's no operation. Absolute session timeout is suitable for scenarios where strict control of the session life cycle is required, such as financial applications; idle session timeout is suitable for applications that want users to keep their session active for a long time, such as social media.

The server session failure can be solved through the following steps: 1. Check the server configuration to ensure that the session is set correctly. 2. Verify client cookies, confirm that the browser supports it and send it correctly. 3. Check session storage services, such as Redis, to ensure that they are running normally. 4. Review the application code to ensure the correct session logic. Through these steps, conversation problems can be effectively diagnosed and repaired and user experience can be improved.
