数组
array_fill
<?php $a=array_fill(2,3,"Dog"); print_r($a); ?>
Array ( [2] => Dog [3] => Dog [4] => Dog )
<?php
$input = array("a", "b", "c", "d", "e");
$output = array_slice($input, 2); // returns "c", "d", and "e"
$output = array_slice($input, -2, 1); // returns "d"
$output = array_slice($input, 0, 3); // returns "a", "b", and "c"
// note the differences in the array keys
print_r(array_slice($input, 2, -1));
print_r(array_slice($input, 2, -1, true));
?>
以上例程会输出:
Array
(
[0] => c
[1] => d
)
Array
(
[2] => c
[3] => d
)
