php怎么把数组转换成json格式化

Answer 1

可以使用json_encode完成转换，

范例：

<?php
$arr = array ('a'=>1,'b'=>2,'c'=>3,'d'=>4,'e'=>5);
echo json_encode($arr);
?>

以上例程会输出：

{"a":1,"b":2,"c":3,"d":4,"e":5}

Answer 2

<?php
$array=array(
	"data1"=>"data1",
	"data2"=>"data2",
	"data3"=>array(
		"data11"=>"data11",
		"data22"=>"data22",
		"data33"=>"data33"
	),
	"data4"=>array(
		"data111",
		"data222",
		"data333"
	)
);
echo json_encode($array);
?>

是不是这个？输出的JSON：

{"data1":"data1","data2":"data2","data3":{"data11":"data11","data22":"data22","data33":"data33"},"data4":["data111","data222","data333"]}
