Is there a built-in that re-indexes an array if one of the elements were removed?
echo '<pre>';
$array = array('first','second','third','fourth','fith');
unset ($array[1]);
sort($array);
print_r($array);
gives me the output below. notice how it is out of “order.”
Array
(
[0] => first
[1] => fith
[2] => fourth
[3] => third
)
i know sort() is to sort it by alpha, but would like an output like this instead (re-sort based on index number)
Array
(
[0] => first
[1] => third
[2] => fourth
[3] => fith
)
[Edit]
n/m. i think i found it – ksort()
[Edit2]
arg! it didn’t re-index the list. ksort() didn’t do it
[Edit3]
Found it! array_values() will re-index the list.
echo '<pre>';
$array = array('first','second','third','fourth','fith');
unset ($array[1]);
$array = array_values($array);
print_r($array);
Array
(
[0] => first
[1] => third
[2] => fourth
[3] => fith
)
