Question

PHP是怎么返回json格式的数据

Answer 1

php 输出JSON格式,使用json_encode函数即可
例如:
<?php
header('Content-type: text/json');
$fruits = array (
"fruits" => array("a" => "orange", "b" => "banana", "c" => "apple"),
"numbers" => array(1, 2, 3, 4, 5, 6),
"holes" => array("first", 5 => "second", "third")
);
echo json_encode($fruits);
?>
得到结果:
{"fruits":{"a":"orange","b":"banana","c":"apple"},"numbers":[1,2,3,4,5,6],"holes":{"0":"first","5":"second","6":"third"}}

Answer 2

<?php
echo json_encode(array('a'=>'bbbb','c'=>'ddddd'));
?>
结果输出为json格式的字符串{"a":"bbbb","c":"ddddd"}
