可以試試json

PHP code

$coord = array (    0=>array (        "x" => "102.00001",        "y" => "20.12321"    ),    1=>array (        "x" => "300.22",        "y" => "111.22"    ),    2=>array (        "x" => "202.1121",        "y" => "30.2122"    ));$str = json_encode($coord);echo $str;//[{"x":"102.00001","y":"20.12321"},{"x":"300.22","y":"111.22"},{"x":"202.1121","y":"30.2122"}]
