Array question

[farsighted]

Hey,

 

I'm really new to php, and coding in general, so please forgive me if anything I say is dumb. What I'm trying to do is this:

I have a variable ($variable) that I want to compare to the instances of an array ($values) using an if/else statement like this:

if ($variable == $values) {

code to be executed

 

What I need to know is, how do I compare the variable to all the instances of the array? Would I have to use a loop function? If so, I'd need to be pointed in the right direction... Or can I just do something like:

if ($variable == $values[0, 1 ,2]) { //I know that doesn't work, but is there some sort of way like that to do it? Is there a way of saying if ($variable == $values[0] or $values[0] or $values[0]) {

code to be executed

 

Thanks

Shane

you can use function in_array(), no need to loop thru array if you just want to compare to all elements

 

<?php 
$arr = array("a", "b", "c");
$variable = "a";

if(in_array($variable, $arr)) {
..code to be executed
}

?>

Thanks for the quick reply!

 

I'll give that a try...
