php中数组中第二大数的程序逻辑
function secondHighest(array $arr) {
sort($arr);
echo $arr[sizeof($arr)-2];
}
secondHighest(array( 4, 9, 5, 2, 8, 0, 3, 22));
在php中查找数组的最大元素
<?php
$array = array(5,7,81,0,12);
$max1 =0 ;
$max2 = 0;
for($i=0; $i $max1)
{
$max2 = $max1;
$max1 = $array[$i];
}
else if($array[$i] > $max2)
{
$max2 = $array[$i];
}
}
echo "Maximum value = ".$max1;
echo "
";
echo "Second maximum Value =".$max2;
?>
