On this page, you can find comprehensive information about encrypting and decrypting a string in PHP. Learn how to do it with the functions of openssl.
由于出于安全考虑,参数传递的时候需要进行加密和解密,一个比较简单的方法是直接使用php中的函数mcrypt_encrypt、mcrypt_decrypt,一个加密,一个解密,但是问题又出现了,这个加密过程中会产生一些使url混乱的符号,于是在加密后对加密字符再进行一次处理,然后多了一一次解析: $key = "miyao";//密钥$string="jiami"//需...
