# PHP Arrays

Sort an array of temperatures in ascending order and retrieve 5 coolest and 5 warmest temperatures.

  

### Initialize array

`$array = array(68, 70, 72, 58, 60, 79, 82, 73, 75, 77, 73, 58, 63, 79, 78, 68, 72, 73, 80, 79, 68, 72, 75, 77, 73, 78, 82, 85, 89, 83);`  

  

### Print array

`print_r($array);`  

  

#### Output:  

![printArray](https://user-images.githubusercontent.com/32812640/82562015-0a62d080-9b92-11ea-8490-95c4582b636c.PNG)  

  

### Sort array in ascending order


for ($j = 0; $j < count($array); $j++) {

  for ($i = 0; $i < count($array) - 1; $i++) {

    if ($array[$i] > $array[$i + 1]) {

      $temp = $array[$i + 1];

      $array[$i + 1] = $array[$i];

      $array[$i] = $temp;

    }

  }

} 

  

  

### Average of all tempratures


$total = 0;

foreach ($array as $key => $value) {

  $total = $total + $value;

}

echo ($total / count($array)) . ' is the average of the temperatures.';

  

  

#### Output:  

![average](https://user-images.githubusercontent.com/32812640/82561574-3d589480-9b91-11ea-9c6c-ee15a22c8802.PNG)  

  

### Five coolest tempratures


$max = count($array);  

for ($i = $max - 5; $i < $max; $i++) {  

  echo "$array[$i]℉ temperature";  

}



  

#### Output:  

![coolest](https://user-images.githubusercontent.com/32812640/82561782-958f9680-9b91-11ea-8389-11f4e350b07e.PNG)  


  

### Five warmest tempratures


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

  echo "$array[$i]℉ temperature";  

}



  

#### Output:  

![warmest](https://user-images.githubusercontent.com/32812640/82561725-798bf500-9b91-11ea-8094-924e9d476215.PNG)
