一、array_map() 1、array_map()函数将用户自定义函数作用到数组中的每个值上,并返回用户自定义函数作用后的带有新值的数组,若函数作用后无返回值,则对应的新值数组中为空。 2、回调函数接受的参数数目应该和传递给array_map()函数的数组数目一致。 3、提示:您可以向函数输入一个或者多个数组。 若相函数输入2个数组,
array_slice();//截取一段值 $arr2=array_slice($arr,0,3); 0开始位置,3个 ,返回值:截取的内容 array_splice();//截取一段值,保留一段值 返回值:截取后剩下的内容 //array_splice(3,3,"aa"); 从下标3的位置开始向后截取3个值,aa替换截取的内容 array_combine();//合并,一个是key,一个是valu...
