4,204 PointsEnhancing a PHP application - not sure what should be changed in this foreach loop
Question: The $numbers array in the code below contains one thousand numbers. I need to count how many of these numbers fit into each of the following categories: (a) how many of them are between 1 and 1000 inclusive, (b) how many of them are less than 1, and (c) how many of them are greater than 1000. I have created a foreach loop to look at each number one after the other, but right now itβs treating every number like it belongs in all three categories. Modify the code below so that the counts are correct.
I'm just completely stumped as to what i need to change to ensure the loop only counts the numbers as described. Do i need an IF statement with the math calculation for each variable being looped through?
The preview isnt much help and the other include files are not in the task so i cant even get the task in a browser and try and figure it out
<?php
require_once('model.php');
$numbers = get_numbers();
$count_less_than_one = 0;
$count_between_one_and_thousand = 0;
$count_greater_than_thousand = 0;
foreach ($numbers as $number) {
$count_less_than_one += 1;
$count_between_one_and_thousand += 1;
$count_greater_than_thousand += 1;
}
include('view.php');
?>
