range

(PHP 3>= 3.0.8, PHP 4 )

range --  Create an array containing a range of elements

Description

array range ( mixed low, mixed high [, int step])

range() returns an array of elements from low to high, inclusive. If low > high, the sequence will be from high to low.

New parameter: The optional step parameter was added in 5.0.0.

If a step value is given, it will be used as the increment between elements in the sequence. step should be given as a positive number. If not specified, step will default to 1.

<?php
// array(0,1,2,3,4,5,6,7,8,9)
foreach(range(0, 9) as $number) {
    echo $number;
}

// The step parameter was introduced in 5.0.0
// array(0,10,20,30,40,50,60,70,80,90,100)
foreach(range(0, 100, 10) as $number) {
    echo $number;
}

// Use of characters introduced in 4.1.0
// array('a','b','c','d','e','f','g','h','i');
foreach(range('a', 'i') as $letter) {
    echo $letter;
}
// array('c','b','a');
foreach(range('c', 'a') as $letter) {
    echo $letter;
}
?>

Замечание: Prior to version 4.1.0 the range() function only generated incrementing integer arrays. Support for character sequences and decrementing arrays was added in 4.1.0.
