if statement

jsmith23

I am trying to construct an "if statement" and I am not sure if I can do it this way. There may be a better way.

I want the logic to do this, but I don't know the syntax:

if {
(($var1 = $var2) AND ($var3 = $var4)) OR
(($var1 = $var4) AND ($var3 = $var2))
}

then do whatever.

Thanks.

Hiya,

This is the correct syntax

if(($var1 = $var2) AND ($var3 = $var4)) OR
(($var1 = $var4) AND ($var3 = $var2))
{
//do whatever
}

However, there are always better ways in the design of a program than monstrous if statement. But that comes with practice.

Thanks for the quick response. I am a newbie, but I am learning.

Thanks again.

Oops made a mistake make sure you use the comparion equals (double equal sign)

if(($var1 == $var2) AND ($var3 == $var4)) OR
(($var1 == $var4) AND ($var3 == $var2))
{
//do whatever
}

What could I look into to try to do this better?

Well depends on what your doing heh...there are times when you need a big if statement.

Id have to see the code and what your trying to do.

I have a table tblbets that has team1id and team2id. I am entering 2 teams into the table and I am trying to get it to check to see if the teams have already been entered. It doesn't matter in which order they have been entered.

So, I query the table, place it in an array, and I am using the if statement to check the if the id's are already in the table.

I hope that makes sense.

why dont you query the db, and then see the $mysql_num_rows
if its >0 they are already there.

kinda simpler i think
