<?php 

    $arr = array(0,1,2,3,4); 

    var_dump(array_slice($arr,0,2)); 

    echo "<br/>"; 

    $arr2 = array('a'=>array('a','a','a'),'b'=>array('b','b','b')); 

    var_dump(array_slice($arr2,0,1)); 

?>

返回的結(jié)果如下:
array(2) { [0]=> int(0) [1]=> int(1) }
array(1) { ["a"]=> array(3) { [0]=> string(1) "a" [1]=> string(1) "a" [2]=> string(1) "a" } }

array_slice函數(shù)實(shí)現(xiàn)的分頁(yè)方法非常好用,分享如下:

復(fù)制代碼代碼如下:
