range() create an array from a given range of elements with increment value in PHP

Current PHP usage

range() creates an array of values between a start and an end value. A step lets you skip values or build descending sequences.

$odd = range(1, 9, 2);
print_r($odd);

Use a negative step for descending ranges when the start value is greater than the end value.

$output=range($start, $end, [$step]);

Create an array by taking a range starting from $start and ending with $end with optional increment data of $step. The result is $output an array.

Example

$my_array=range(0,10); // create an array
foreach ($my_array as $element) {
    echo $element . "  ";
}

Output is here

0 1 2 3 4 5 6 7 8 9 10

Example with step value

$my_array=range(0,10,2); 
foreach ($my_array as $element) {
    echo $element . "  ";
}

Ouput is here

0 2 4 6 8 10

Example with step value

$my_array=range(0,100,10); 
foreach ($my_array as $element) {
    echo $element . "  ";
}

Ouput is here

0 10 20 30 40 50 60 70 80 90 100

Example with number decrement step value

$my_array=range(100,0,-10); 
foreach ($my_array as $element) {
  echo $element . "  ";
}

100 90 80 70 60 50 40 30 20 10 0

Example using alphabets

$my_array=range(a,z); 
foreach ($my_array as $element) {
  echo $element . "  ";
}

Output is here

a b c d e f g h i j k l m n o p q r s t u v w x y z

Example using alphabets

$my_array=range(A,H); 
foreach ($my_array as $element) {
  echo $element . "  ";
}

Output is here

A B C D E F G H

Example Using alphabets and step

$my_array=range(A,H,3); 
foreach ($my_array as $element) {
  echo $element . "  ";
}

Output is here

A D G

Range with shuffle()

The array created by using range() maintains an order, either increment or decrement. If you want to randomize the elements by not maintaining any particular order then we can use shuffle() function.

$my_array=range(0,10);
shuffle($my_array);
foreach ($my_array as $element) {
    echo $element . "  ";
}

Output is here

4 5 2 3 7 9 1 8 10 0 6

Above output will change each time you run the script.
