字符串中首字符的位置是 0 而不是 1。

对象：

class Car
{
var $color;
function Car($color="green") {
$this->color = $color;
}
function what_color() {
return $this->color;
}
}

对象转数组

function object_to_array($obj){

$_arr = is_object($obj) ? get_object_vars($obj) :$obj;

foreach ($_arr as $key=>$val){

$val = (is_array($val) || is_object($val)) ? $this->object_to_array($val):$val;

$arr[$key] = $val;

}

return $arr;

}
