字符串替换,如何能做到双向替换?
最近要做一个同义词替换的功能,因为是同义词,所以最好是能双向替换,比如“拜会”和“拜见”,在字符串中出现任何一个都要能替换成另一个。
通常用str_replace只能单向替换,不能实现双向替换。
尝试了一下把同义词做成数组再用str_replace替换,结果却不正确。
$find = array("拜会","拜见");
$replace = array("拜见","拜会");
$arr = array("拜会和拜见");
str_replace($find,$replace,$arr);
结果是:拜会和拜会。
问题是怎么样才能使最后的替换结果是“拜见和拜会”?
------解决方案--------------------
改动一下
- PHP code
$find = array("拜会","拜见");$replace = array("拜见","拜会");$str = "拜会和拜见";echo strtr($str, array_combine($find, $replace));<div class="clear"> </div>

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.
