json_decode用法

$json = '{"a":1,"b":2,"c":3,"d":4,"e":5}';
//解析为json对象
var_dump(json_decode($json));
//解析为数组
var_dump(json_decode($json, true));
代码执行结果
object(stdClass)#1 (5) { 
   
    ["a"] => int(1)
    ["b"] => int(2)
    ["c"] => int(3)
    ["d"] => int(4)
    ["e"] => int(5)
}

array(5) { 
   
    ["a"] => int(1)
    ["b"] => int(2)
    ["c"] => int(3)
    ["d"] => int(4)
    ["e"] => int(5)
}
