loop

here is the function description

test($argv)

$argv is an array , for example $argv=array($from1,$to1,$from2,$to2.....); array items must be even.

$argv=array(1,2,4,5) : this will output values like below:

1_4 1_5 2_4 2_5

the number of arrray $argv's is not constant. maybe 3 or 4 levels of loop will be outputed.

i know this will used RECURSIVE , but i don't know exatly how to code.
