php - Can I set many values for the same variable?

Question

I have a PHP variable that its value = keywords the code searches for

$searchfor = 'error1';

Each time I need to add a new keyword to searchfor, i repeat the function. Can't I for example set

$searchfor = 'error1' and 'error2' and 'error3';

but don't stop the code if one of them didn't exist.

Answer 1

computer programming more verbose than human language. this is so that there is no ambiguity.

No, you must do this:

if( $searchfor == 'value1' || $searchfor == 'value2' || $searchfor == 'value3' )
{
    // do something
}

You must repeat the variable name.

Or you could use an array

$searchfor = 'value1';
$goodValues = array( 'value1', 'value2', 'value3' );
if( in_array( $searchfor, $goodValues ) )
{
    echo 'hi mom';
}

Output:

hi mom

it's up to you to decide which style best suits your needs.
