variable comparison

[wrathican]

hi there.

my problem is that i have three variables, all of which could be different values (numerical between 1 and 4).

i need to compare these vars to each other to see which has the lowest value (1) because i only actually need one value.

 

i have thought about using an if statement something like this

if var1 or var2 or var3 are equal to 1

actual value is set to one

 

if var1 or var2 or var3 are equal to 2

actual value is set to one

 

if var1 or var2 or var3 are equal to 3

actual value is set to one

 

if var1 or var2 or var3 are equal to 4

actual value is set to four

 

but how do format the condition?

i could do it like this:

if(($var1 == 1) || ($var2 == 1) || ($var3 == 1)){
$actualvalue = 1;
}else if(.........

would that be the best way?

or is there an easier way?

Use "min()" math function

 

Syntax:

<?php
$var1 = 18;
$var2 = 3;
$var3 = 153;
$var4 = 82;

echo min($var1,$var2,$var3,$var4); //Prints 3

?>
