How can I find and print all of the numbers between two numbers in PHP?

Question

Right now I'm asking the user for two numbers. I'm trying to print the numbers in between $one and $two assuming $one is smaller than $two.

Answer 1

range gives an array containing all the numbers.

You can iterate over that:

foreach (range($one, $two) as $number)
    echo "$number <br>\n";

Or simply use a loop:

for ($number = $one; $number <= $two; $number++)
    echo "$number <br>\n";

Answer 2

<?php
foreach (range($one, $two) as $number) {
    echo $number." \n";
}
?>

range($one, $two) makes an array of numbers from $one to $two.

<?php
$numbers = range($one, $two);
foreach ($numbers as $number) {
    echo $number." \n";
}
?>

In this example, the array of numbers are first stored in $numbers before they are printed.

If $one is 5 and $two is 10 these examples will output:

5 
6 
7 
8 
9 
10 

Answer 3

Just a simple for loop should do the trick:

for($i=$a; $i<=$b; $i++) {
  echo $i;
}

Answer 4

This sounds like homework...

for ($i=$one+1; $i<$two; $i++)
{
  echo $i . "\n";
}

This really gets you only the numbers between, not the endpoints.

Answer 5

for($i=$one + 1; $i<$two; $i++) {
    echo $i;
}
