1 <?php 2 $a1=array("a"=>"1","b"=>"2","c"=>"3",1,array(1,2)); 3 $result=array_slice($a1,-2,-1); 4 print_r($result); 5 ?>
Array ( [0] => 1 )
http://www.cnblogs.com/4php/archive/2012/10/13/2720208.html 中，的一個例子：
（6）刪除數組（假設數組很長，無法數清數組所含元素的個數）倒數兩個元素。
之前使用的是：
1 <?php 2 $a1=array("Dog","Cat","Horse","Bird","5","6","7","8","9","10"); 3 $n1=count($a1); 4 $n1-=2; 5 array_splice($a1,$n1,2); 6 print_r($a1); 7 ?>
Array ( [0] => Dog [1] => Cat [2] => Horse [3] => Bird [4] => 5 [5] => 6 [6] => 7 [7] => 8 )
如果使用array_slice函數，那么程序會寫成：
<?php $a1=array("Dog","Cat","Horse","Bird","5","6","7","8","9","10"); $a2=array_slice($a1,0,-2); print_r($a2); ?>
Array ( [0] => Dog [1] => Cat [2] => Horse [3] => Bird [4] => 5 [5] => 6 [6] => 7 [7] => 8 )
結果一樣，但是代碼非常簡單，只用了一個array_slice函數進行截取即可。
1.array_slice函數與array_splice函數的區別。
array_slice函數：是通過定義要保留元素的起點和終點，來獲取數組的元素。slice的含義是划分，即划分出要保留的元素。
array_splice函數：是通過定義要刪除元素的起點和終點，來獲取數組的元素。splice的含義是連接，即刪除元素后，將剩下的元素連接起來。
