json_decode

json_decode($json, true) true什么意思

<?php

$json = '{"a":1,"b":2,"c":3,"d":4,"e":5}';

var_dump(json_decode($json));

var_dump(json_decode($json, true));

?>

结果：

object(stdClass)[1]

  public 'a' => int 1

  public 'b' => int 2

  public 'c' => int 3

  public 'd' => int 4

  public 'e' => int 5

array (size=5)

  'a' => int 1

  'b' => int 2

  'c' => int 3

  'd' => int 4

  'e' => int 5

true返回值是数组,否则返回值为object
