php输出字符串方法总结

2. $v = new test();
3. print_r($v);
4. var_dump($v);
5. class test {
6. public $num = 1;
7. public $str = "222";
8. public $bln = true;
9. function test() {
10. global $num;
11. }
12. }

复制代码

结果为： test object ( [num] => 1 [str] => 222 [bool] => 1 ) object(test)#1 (3) { ["num"]=> int(1) ["str"]=> string(3) "222" ["bool"]=> bool(true) }
