you need to use "==" instead of "=" "==" is used when comparing values (i.e. is this "==" to that) "=" is used to set something's value (i.e. this "=" that)

I just cant seem to work out why this doesn't work. My PHP book doesn't explain "if" statements very well so i have no idea if i am breaking a rule. $system_day = date("j"); for($day = 1; $day < 32; $day++){ if($day = $system_day){ echo "match!"; } else{ echo "no match"; } } the problem i am experiencing is that it seems the "if" statement is setting the $day value to equal $system_day instead of comparing their values.... if i add echo "Day: " . $day . " System_day: " . $system_day; before and after the if statement then the first result is something like Day: 1 System_day: 29 after the "if" statement has executed the result is Day: 29 System_day: 29 so you see, instead of "if" comparing $day to $system_day it is making $day equal to $system_day. any ideas why and how to fix this? help is most appreciated :) -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
