取出数组中最大值解决方案
取出数组中最大值
$t=array('1','2','3','4','5');
$result=array_search(max($t),$t);
echo '最大值:'.$result;
?>
这个结果为什么显示是4
吐血了
------解决方案--------------------
max($t)是5
$result=array_search(5,$t);
这是在$t数组中寻找值为5的元素 返回这个元素对应的键。
5存在于这个数组 并且键是4 所以返回4是ok的
数组的键从0开始
你的程序最后一句话改为 echo '最大值的键:'.$result;
------解决方案--------------------
echo '最大值:'. max($t);
何必要画蛇添足的 array_search 呢?
------解决方案--------------------

This can cause problems if you plan to use your iPhone as your main camera for large projects or travel.
