Question

Okay, so I have a few possible matches that I need to test. It can either equal A or B, so the obvious way to test it would be something like this:

if($val=="A"||$val="B"){
    echo "yup";
}

I was just wondering if their were an easier way to test values without restating the variable for every value, like this (I know this doesn’t work):

if($val==("A"||"B")){
    echo "yuppers";
}

Is something like this possible?

Answer 1

You can use in_array

$array = array('A','B','other values');
if(in_array($val, $array)){
    // value is in array
}else {
    // invalid value
}
