输出
-------------------------------
现在的数组
array(3) { ["name"]=> string(9) "李小龙" ["tel"]=> string(11) "11111111111" ["age"]=> string(2) "12" }
-------------------------------
数组转对象
object(stdClass)#1 (3) { ["name"]=> string(9) "李小龙" ["tel"]=> string(11) "11111111111" ["age"]=> string(2) "12" }
输出对象属性
string(9) "李小龙"
-------------------------------
对象转数组
array(3) { ["name"]=> string(9) "李小龙" ["tel"]=> string(11) "11111111111" ["age"]=> string(2) "12" }
输出数组数值
string(9) "李小龙"
-------------------------------
Json到数组
array(8) { ["a"]=> string(6) "哈哈" ["b"]=> string(3) "我" ["c"]=> string(3) "数" ["d"]=> string(3) "一" ["e"]=> string(1) "3" ["f"]=> string(1) "2" ["g"]=> string(1) "1" ["h"]=> string(12) "别生气了" }
官方换种方法
对象
object(stdClass)#2 (8) { ["a"]=> string(6) "哈哈" ["b"]=> string(3) "我" ["c"]=> string(3) "数" ["d"]=> string(3) "一" ["e"]=> int(3) ["f"]=> int(2) ["g"]=> int(1) ["h"]=> string(12) "别生气了" }
属性:哈哈
数组
array(8) { ["a"]=> string(6) "哈哈" ["b"]=> string(3) "我" ["c"]=> string(3) "数" ["d"]=> string(3) "一" ["e"]=> int(3) ["f"]=> int(2) ["g"]=> int(1) ["h"]=> string(12) "别生气了" }
-------------------------------
数组到Json
array(8) { ["a"]=> string(6) "哈哈" ["b"]=> string(3) "我" ["c"]=> string(3) "数" ["d"]=> string(3) "一" ["e"]=> string(1) "3" ["f"]=> string(1) "2" ["g"]=> string(1) "1" ["h"]=> string(12) "别生气了" }
string(136) ""{\"a\":\"\u54c8\u54c8\",\"b\":\"\u6211\",\"c\":\"\u6570\",\"d\":\"\u4e00\",\"e\":3,\"f\":2,\"g\":1,\"h\":\"\u522b\u751f\u6c14\u4e86\"}""
希望本文所述对大家PHP程序设计有所帮助。
