If Or

[GarryJones]

I need to test for one of several values. Can I include these in a
single "if" statement

I tried using OR but it does not work. In the actual file I need to
check if a supplied user input meets one of about 170 possible code
combinations.

This does not work

if ($var == 1 OR 3 OR 7 OR 8 OR 9 OR "Table" OR "Chair"){
echo 'yes';
} else {
echo 'no';
}

A long winded way to do it and the only way I know how to use OR is...

if ($var == 1 || $var == 3 || $var == 7 || $var == 7 || $var == 9 ||
$var == "Table" || $var == "Chair")
....etc

But I would like to just list the values (and not the $var == for
every possible condition

Put the values in an array and use in_array()

if ( in_array( $var, array( 1, 3, 7, 9) ) {
// do something
}

Re: If Or

well, this is the best i can offer based on what you've described...

function checkInput($val ue)
{
static $combination = array(
1 ,
3 ,
7 ,
8 ,
9 ,
'Table' ,
'Chair'
)
return in_array($value , $combination, true);
}

echo checkInput($var ) ? 'yes' : 'no';


that's one way. and, you could build $combination from a db so that the
function scales. another way would be to write (or store and retrieve) a
regular expression or series of them:

/^[13789]|table|chair$/gi

then you'd preg_match a true or false answer from that.

hth,

Hello,

If you have array of all possible 170 values then you can try with
in_array function. If you don't have array then prepare it and then
check it.

Hardcoding more than 100 conditions doesn't seem to be a good idea in
any case. Put them in db and use the power of sql to find if the value
matches.
