$a = array(2,4,1,3,7,5);
$a = sort($a);
print_r($a);
Copy after login
结果:1;
百思不得其解!求解!!!
------解决方案--------------------1 表示排序成功
------解决方案--------------------PHP code
$a = array(2,4,1,3,7,5);
echo sort($a);
print_r($a);
<br><font color="#e78608">------解决方案--------------------</font><br>sort()是取地的,返回的是是否成功,true==1,所以你应该输出$a <div class="clear">
</div>
Copy after login
