Updating mysql row

Historically the mysql extension was the only way until PHP 5.0 (circa 2004).

After that mysqli appeared, which is an improved version of the older mysql driver.

The error/warning in PHP 5.5-5.6 will look like this: $link = mysql_connect('localhost', 'my_user', 'my_password'); if (!

$link) $db_selected = mysql_select_db('my_db', $link); if (!

Instead of Converter tool There’s actually a free converter tool available.And also PDO, which gives you an abstraction layer for different databases.Unfortunately there’s still a lot of legacy code around using the old mysql extension, and that must be updated to use the newer mysqli extension.Here is my example..normal update command would be: // question ID ranges from 1-20 // $questionid == 1, $member_id==1 UPDATE table_Foo Bar SET answer One='$ans1Val', answer Two='$ans2Val', answer Three='$ans3Val' WHERE member_id='$memberid' AND question_id='$questionid'; // $questionid == 2, $member_id==1 UPDATE table_Foo Bar SET answer One='$ans1Val', answer Two='$ans2Val', answer Three='$ans3Val' WHERE member_id='$memberid' AND question_id='$questionid'; ..UPDATE table_Foo Bar SET answer One='yes', answer Two='no', answer Three='yes' WHERE member_id = 1 AND question_id = 1; UPDATE table_Foo Bar SET answer One='no', answer Two='no', answer Three='yes' WHERE member_id = 1 AND question_id = 2; UPDATE table_Foo Bar SET answer One='yes', answer Two='yes', answer Three='no' WHERE member_id = 1 AND question_id = 3; oh, absolutely!!

It can be used to convert automatically all the old mysql code to the new mysqli code and it does a pretty good job.
