array(3) {
["a"]=>
string(8) "wuyanzhu"
["b"]=>
string(13) "huangxiaoming"
["c"]=>
string(8) "ninzetao"
}
a ---WUYANZHU
b ---HUANGXIAOMING
c ---NINZETAO
用自訂函數test_print執行後的效果：array(3) {
["a"]=>
string(8) "wuyanzhu"
["b"]=>
string(13) "huangxiaoming"
["c"]=>
string(8) "ninzetao"
}
看一下手冊，手冊寫的很好理解，但你得先回呼函數
