PHP如何在数组指定位置插入元素

$arr = array ( ‘a’ , ‘b’ , ‘c’ , ‘d’ , ‘e’ , ‘f’ , ‘g’ ); //目标数组bai $i_arr = array ( ‘1’ , ‘2’ ); //要插入bai的数组 $n = 2 ; //插入的位置 array_splice ( $arr , $n , 0 , $i_arr ); print_r ( $arr );

Array ( [ 0 ] => a [ 1 ] => b [ 2 ] => 1 [ 3 ] => 2 [ 4 ] => c [ 5 ] => d [ 6 ] => e [ 7 ] => f [ 8 ] => g )
