php连接mysql数据库执行sql语句无结果!求搭救
菜鸟初次接触php与mysql数据库的连接操作,模仿书上写了以下代码,发现可以连接上数据库,但是sql语句却总是没有被执行,sql语句是没问题的,在phpMyAdmin中是可以成功执行的,可是到了这里就不行,求大神搭救看看问题出在哪
<?php $host="localhost"; $userName="cheng"; $password="11111111"; $dbName="db_student"; $connID=mysqli_connect($host,$userName,$password); /*if ($connID){echo "ok";} else {echo "error";} */ mysqli_select_db($connID,$dbName); mysqli_query($connID,"set names gbk"); //$query=mysqli_query($connID,"SELECT sno,sname,class,chinese,math,english FROM tb_student"); $result=mysqli_query($connID,"INSERT INTO tb_student(sno, sname, class, chinese, math, english) VALUES ('012531','sbsb','12ji','70','70','70')"); if ($result){echo "ok";} else die('Error: ' . mysql_error()); mysqli_close($connID);

In PHP, password_hash and password_verify functions should be used to implement secure password hashing, and MD5 or SHA1 should not be used. 1) password_hash generates a hash containing salt values to enhance security. 2) Password_verify verify password and ensure security by comparing hash values. 3) MD5 and SHA1 are vulnerable and lack salt values, and are not suitable for modern password security.
