PHP에서 일반적으로 사용되는 방법은 무엇입니까?

$my_array = array("Dog","Cat","Horse");
list($a, $b, $c) = $my_array;//或者
list($a, , $c) = $my_array;

$str = 'one,two,three,four';
// 零 limit
print_r(explode(',',$str,0));
// 正的 limit
print_r(explode(',',$str,2));
// 负的 limit
print_r(explode(',',$str,-1));

     <?php
         $xmldata=file_get_contents("php://input");
        $data=simplexml_load_string($xmldata);
         print_r($data);
    ?>

$array = array('lastname', 'email', 'phone');
 $comma_separated = implode(",", $array);
 echo $comma_separated; // lastname,email,phone
 $pizza  = "piece1 piece2 piece3 piece4 piece5 piece6";
$pieces = explode(" ", $pizza);
 echo $pieces[0]; // piece1
echo $pieces[1]; // piece2
