定义和用法

array_walk() 函数对数组中的每个元素应用用户自定义函数。在函数中，数组的键名和键值是参数。

     ";}$a=array("a"=>"red","b"=>"green","c"=>"blue");array_walk($a,"myfunction","has the value");?>

结果

a has the value redb has the value greenc has the value blue

其实传参，数组哪里($value)可以加个&,那就代表引用(指针)，把原始数组也更改了.

 

     ";}$a=array("a"=>"red","b"=>"green","c"=>"blue");array_walk($a,"myfunction","has the value");?>
