Can this be done??

peppino

will this work?

if ($value != '1' || '2'){
do this
}

It can be done, but the do this will always be executed 😉

Figure it out 😉

just to exapand a bit on madwormer2's post:

you are asking PHP to evaluate 2 distinct statements:
1. if $value != '1' equals boolean TRUE
2. if '2' equals boolean TRUE

you are saying to conditionally excute code if either one is true (by using the || operator). the 1st statement may or may not be true. the second one will always be true, hence, the code will always be excecuted.

if suspect what you probably want is this:

if ($value != '1' && $value != '2')
{
	// do something is $value is neither 1 nor 2
}

madwormer2

Ya, thats it (I'm no good at explanations, leave it to the experts 😉 )

i want to execute the code only if $value = anything other then art and prints.
example
if ($value != 'art' || $value != 'prints'){
do this
}

i know i can write it like above, but i was just curious of you could do something like this maybe:

if ($value != ('art' || 'prints')){
do this
}

that's wrong then. you would want the && operator, not the || operator.

you should look at the [man]switch[/man] statement.

peppino

yeah so, is there something in php that will allow you to do like "if $value = anything other then these 5 specific words" execute (or dont) the code, without having to type out each of the 5 words and use either the && or || symbols

peppino

ok cool thanks devin.

you may want to check out [man]strcmp[/man] if you are comparing strings...there was an interesting thread regarding false positives when comparing strings using "==" (doube equals) instead of strcmp.
