php文件中的sql的分割问题 $query='Select * from authorized_users where name= "'.$userid.'" and password=sha1("'.$password.'")'; 这样写对吗? [解决办法] 字符串是用单引号括起来的 [解决办法]
$query="Select * from authorized_users where name= '$userid' and password='{sha1($password)}'"; [解决办法] $query='Select * from authorized_users where name= "'.$userid.'" and password=sha1("'.$password.'")'; 语法正确,但可读性不强
$query="Select * from authorized_users where name='$userid' and password=sha1('$password')"; 这样是不是清爽些?
