finding multiple substrings in a string

[AN-net]

how would i go about finding multiple substrings in a string. should i use strpos but how do i more than one? should i use a switch?

i.e.:

switch($foo)
{
case strpos($foo, 'bar'):
do whatever
break;
case strpos($foo, 'foo');
do whatever
break;
}


any suggestions:)

Why not just an IF for each one ?


if (strpos($foo, 'bar'))
{
do whatever
}
if (strpos($foo, 'foo'))
{
do whatever
}
