Take a look at func_num_args() and func_get_args()
<?php
function multiArgs() {
list( $numArgs, $args )
= array( func_num_args(), func_get_args() );
switch( $numArgs ){
case 1:
// one var passed
break;
case 2:
// two vars passed
echo "You passed two vars: "
. join( ', ', $args ) . "<br />\n";
break;
case 3:
// three vars passed
break;
default:
// error or default handler for
echo "You passed $numArgs vars: "
. join( ', ', $args ) . "<br />\n";
break;
}
// do stuff...
}
multiArgs( 'foo', 'bar' );
multiArgs( 'is', 'this', 'what', 'you', 'want', 'to', 'do?' );
?>
