输出的那个语句是一个合法的PHP赋值语句。
你是不是想直接赋值给一个数组呀，那你看看下面的例子代码：
<?php
$json=<<<END
[{0:{s_id:'1999',name:'元素'},1:{s_id:'2049',name:'时韵'},2:{s_id:'2050',name:'里程'},3:{s_id:'2051',name:'CIVIC'},4:{s_id:'2927',name:'pilot'},5:{s_id:'2857',name:'insight'},6:{s_id:'2904',name:'S2000'}}]
END;
$arr='$arr=';
for ($i=0;$i<strlen($json);$i++){
$c=substr($json,$i,1);
if ($c=='[' || $c=='{') $arr.='array(';
elseif ($c==']' || $c=='}') $arr.=')';
elseif ($c==':') $arr.='=>';
else $arr.=$c;
}
$arr.=';';
eval($arr);
print_r($arr);
?>

json_decode有2个参数...数据源....第二个参数是返回形式..默认是对象..如果是true的话..就是数组
比如 json_decode($value, true)
