PDO更新不更新数据库

Question

I can't get this code to update my, mysql database.

        $SQL = $odb -> prepare("UPDATE `LB` SET `running` = `running` + 1 WHERE `url`= :url");
        $SQL -> execute(array(":url"=> $url ));

May someone please help, I have searched for this and couldn't find something like this.

Don't do :url in your array, there is no need for it.

You can also use a question mark in place of your =:url like so:

url=?

Then in your array, you can either place a direct value:

$SQL->execute(array($url));

Or you can bind values incrementally:

$SQL->bindValue(1, $url, PDO::PARAM_INT);
$SQL->execute();

Except, instead of using PDO::PARAM_INT, you would use your own parameters...

So I'm guessing in your instance you would use PDO::PARAM_STR

Hopefully this helps :)
