How to create an array with X amount of values, based on a string?

Question

I am trying to create an array based on the value of a string (integer), for example:

// my string
$dogs = '2';

// my array
$dogs_array = array(
                [0] => 'Dog 1',
                [1] => 'Dog 2'
              );

So if the string was 4 there would be 4 items in the array. Is this possible? If so how can this be done?

Thanks in advance.

With for or foreach

$i = 1;
$dogs_count = (int)$dogs;
while ($i <= $dogs_count) {
    $dogs_array[] = 'Dog ' . $i++;
}
print_r($dogs_array);

I think you should use loop index in $dogs_array[].

@Mohammad Why should an index be used? PHP automatically increments a numeric index for you, so no need to do it in your code

<?php
// my string
$dogs = '5'; //initialize your variable

$dogsArray = array(); // initialize an empty array

for($i =1; $i <= $dogs; $i++)
{
    array_push($dogsArray, 'Dog '.$i);
}

var_dump($dogsArray);

?>

$count = (int) $dogs;
$dogs_array = [];
for($i = 0;$count>$i; $i++){
    $dogs_array[$i] = "Dogs ".$i;
}
print_r($dogs_array);
