arrays - PHP: list() set variables dynamically form string (read any CSV file as formatted order)

Can I set variables names as csv title (first line)?

I do think it, so I code this:

$string = "date, name, age"; // csv file title order format
$tit = explode(", ", $string); //array('date', 'name', 'age'); //will be called: $_date

//run php function to find a specific line
$arr = array('bash', 'monkey', 'badger'); //returned line
foreach ($tit as $i => $nam) { 
    $e = "_" . $nam; 
    $$e = $arr[$i];
} 
//set variables contents as title name
echo $_name; //monkey
Copy code

Works perfectly: Try it

But how to turn it into PHP function?

function toList ($tit,$arr) {
    foreach ($tit as $i => $nam) { 
        $e = "_" . $nam; 
        $$e = $arr[$i];
    }
}

$tit = array('date', 'name', 'age'); //will be called as: $_date
$arr = array('bash', 'monkey', 'badger');
    
toList($tit,$arr);
    
echo $_date;
Copy code

As function, code breaks.

How should code it to Php function works?
