在mysql_query语句中绑定变量

Question

Example mysql_query:

$query=mysql_query("SELECT `col1`, `col2` FROM `table` WHERE
`col1`='$escapedvariable' ");

I know the above is not good in practice.

Better query using prepare and execute

$pSt = $dbh->prepare('SELECT col1, col2 FROM table WHERE col1=:col1);

$pSt->execute(array(':col1'=>$escapedvariable);

$status=$pSt->errorCode();

Question: Can I use mysql_query with bound variables for added security?

Answer 1

不，你必须使用mysqli -functions或PDO 。
