range --
Create an array containing a range of elements
Description
array range ( mixed low, mixed high)
range() returns an array of elements from
low to high,
inclusive. If low > high, the sequence will be from high to low.
Exemplu 1. range() examples
foreach(range(0, 9) as $number) { echo $number; } foreach(range('a', 'z') as $letter) { echo $letter; } foreach(range('z', 'a') as $letter) { echo $letter; }
Notã:
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.
Exemplu 2. Simulating decrementing ranges and character sequences
# array_reverse can be used to flip the order of a range foreach(array_reverse(range(0,9)) as $number) { echo $number; }
# array_map() can be used to turn integers into characters using chr() foreach(array_map('chr', range(ord('a'),ord('z'))) as $character) { echo $character; }
