<tr <?php if($i&1)echo ' class="alternate"'?>>
这段代码位于一个循环内,$i是自增量,目的是为了奇数行,加上class,使其高亮
我习惯与用Zend Studio进行代码整理,ctrl+shift+f 但是在这种情况下貌似出了点问题
在偶数行,显示的应该是
在PHP格式化部分有个white-space 我把里面所有的空格都取消了,没有任何作用。但是在HTML的格式化部分,也没找到类似的功能,大能们帮我想想办法把。
回复讨论(解决方案)
这不是很正常吗?
html 标记中,标记名和属性之间不就是应该有一个空格将他们分开吗?
html之间有空格隔开是正常的,但html和php代码之间有空格,就会造成一些问题,最常见的就是我提出的那个问题
空格是你自己打上的好么。。
按 ctrl+shift+f 就自动有空格了
为了整理格式,时不时的都要进行一次格式化
空格是你自己打的。。。。。。
看看
看来是软件特性了,没办法解决了

Session regeneration refers to generating a new session ID and invalidating the old ID when the user performs sensitive operations in case of session fixed attacks. The implementation steps include: 1. Detect sensitive operations, 2. Generate new session ID, 3. Destroy old session ID, 4. Update user-side session information.

PHP sessions have a significant impact on application performance. Optimization methods include: 1. Use a database to store session data to improve response speed; 2. Reduce the use of session data and only store necessary information; 3. Use a non-blocking session processor to improve concurrency capabilities; 4. Adjust the session expiration time to balance user experience and server burden; 5. Use persistent sessions to reduce the number of data read and write times.

The security of PHP sessions can be achieved through the following measures: 1. Use session_regenerate_id() to regenerate the session ID when the user logs in or is an important operation. 2. Encrypt the transmission session ID through the HTTPS protocol. 3. Use session_save_path() to specify the secure directory to store session data and set permissions correctly.
