Question

I would like to return multiple arrays and then separate them.

function cal(){
    $st1=array('1','2'); 
    $st2=array('1','2');
    return $st1."-".$st2;
}

call it

$mainstring=explode("-",cal())
print_r($mainstring[0]);
print_r($mainstring[1]);

I want to get original array of $st1 and $st2.

Please help.

Answer 1

Simply change your function cal() to

function cal(){
    $st1=array('1','2'); 
    $st2=array('1','2');
    return array($st1,$st2);
}

And then do

$mainstring=cal();
print_r($mainstring[0]);
print_r($mainstring[1]);
