Question

I have this string in PHP:

$str = 1,3,6,5 

These numbers can change and the length of the set can change to more or less than four. I want to convert to a MySQL query like this in PHP:

$qry = mysql_query("SELECT * FROM tbl WHERE id = 1 or id = 3 or id = 6 or id = 5")

It should be easy, but I don’t know how to do it.

I will be grateful for any help.

Answer 1

You could use IN.

$query = mysql_query("SELECT * FROM table WHERE id IN ($str)");

Make sure $str is validated first to prevent sql injection.
