php函数mysql_query批量执行多句sql语句
正常情况下用php的mysql_query函数是不能批量执行多句CREATE TABLE之类的语句的;
而有些场景;比如说有一个sql备份文件、又或是程序初始化时创建数据表结构的时候需要批量执行文件中的sql语句;
解决这个问题可以用explode函数按';'号把sql语句拆成数组;再通过循环执行mysql_query即可;因为每句sql都是以';'号结束的;
但是考虑到sql语句中可能有实体符号 之类的;如果按';'号来拆;容易误伤;所以用preg_split正则来拆更靠谱;
示例环境:
sql文件:./thinkbjy.sql
$sql_array=preg_split("/;[\r\n]+/", file_get_contents('./thinkbjy.sql')); foreach ($sql_array as $k => $v) { mysql_query($v,$link); echo mysql_error().'<br>'; }
执行 echo mysql_error().'
';用来查看是否有错误;

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,

In PHP8, match expressions are a new control structure that returns different results based on the value of the expression. 1) It is similar to a switch statement, but returns a value instead of an execution statement block. 2) The match expression is strictly compared (===), which improves security. 3) It avoids possible break omissions in switch statements and enhances the simplicity and readability of the code.
