PHP calculation displays average temperature, five minimum and maximum temperatures

PHP calculation displays the average temperature, five minimum and maximum temperatures. The recorded temperatures are 78,60,62,68,71,68,73,85,66,64,76,63,75,76,73,68,62,73,72,65,74,62,62,65 ,64,68,73,75,79,73.

Let's use specific code examples to introduce to you the PHP method of calculating the average temperature, the five lowest and the highest temperatures in the above-mentioned recorded temperatures.

Code examples are as follows:

<?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(&#39;,&#39;, $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].", ";
}

Output:

平均温度为：70.6                               
五个最低温度：60,62,63,63,64，
五个最高温度：76,78,79,81,85，

Related functions:

explode() The function represents using one string to split another string

count() The function represents counting the number of cells in the array or the number of attributes in the object

sort()The function represents sorting the array. When this function ends the array cells will be rearranged from lowest to highest.

Note:

$tot_temp = $temp is equivalent to $tot_temp=$tot_temp $temp
