AND and OR by leito on 02-19-2004 at 04:47 AM
Hi, again! hahaha, I want to make something like this in PHP
if ( $a=yes OR ($b<=10 AND $c<=10) { etc.
Were, <= means "smaller or equal to"
and one condition is $a=yes
and the other conditions is $b<=10 AND $c<=10
I think this could be like...
if ($a=="yes" || ($b<="10" && $c<=10)) {
My question is can i group conditions using ()? Is <= the way you write "smaller or equal to"?
Thank you in advance for your help.

quote:Yes. The example you posted should work fine, though I'd remove the quotes around "10" as it's an integer, not a string.

Just in case you didn't know, by the way, if you want it to execute only of one of the two are true and not both, use XOR.

fluffy what does XOR means? what I want is that if one condition is true, "good to go" haha.
And WDZ thanks, for the "less than or equal to" hahaha, I learn something new!

XOR is false if the two conditions are verified, true when one and only one of the two conditions is verified

XOR: eXclusive OR: A XOR B: or A or B but not both at the same time
