PHP计算显示平均温度、五个最低及最高温度

<?php

$month_temp = "78, 60, 62, 68, 71, 68, 73, 85, 66, 64, 76, 63, 81, 76, 73,

68, 72, 73, 75, 65, 74, 63, 67, 65, 64, 68, 73, 75, 79, 73";

$temp_array = explode(',', $month_temp);

$tot_temp = 0;

$temp_array_length = count($temp_array);

foreach($temp_array as $temp)

{

    $tot_temp += $temp;

}

$avg_high_temp = $tot_temp/$temp_array_length;

echo "平均温度为: ".$avg_high_temp."

";

sort($temp_array);

echo " 五个最低温度：";

for ($i=0; $i< 5; $i++)

{

    echo $temp_array[$i].", ";

}

echo "五个最高温度：";

for ($i=($temp_array_length-5); $i< ($temp_array_length); $i++)

{

    echo $temp_array[$i].", ";

}

结果：

 

<?php

$month_temp = "78, 60, 62, 68, 71, 68, 73, 85, 66, 64, 76, 63, 81, 76, 73,

68, 72, 73, 75, 65, 74, 63, 67, 65, 64, 68, 73, 75, 79, 73";

$temp_array = explode(',', $month_temp);

$tot_temp = 0;

$temp_array_length = count($temp_array);

foreach($temp_array as $temp)

{

    $tot_temp += $temp;

}

$avg_high_temp = $tot_temp/$temp_array_length;

echo "平均温度为: ".$avg_high_temp."

";

sort($temp_array);

echo " 五个最低温度：";

for ($i=0; $i< 5; $i++)

{

    echo $temp_array[$i].", ";

}

echo "五个最高温度：";

for ($i=($temp_array_length-5); $i< ($temp_array_length); $i++)

{

    echo $temp_array[$i].", ";
