That could mean a lot of things. I'm going to assume you have a simple
indexed array and want to remove any entries where array[index] == FALSE,
and reindex the array.
The most elegant way is to copy all the values you want to keep to a new
array.
$a = array(FALSE, 2, 3, FALSE, 5, FALSE, 7, FALSE, FALSE, FALSE);
$b = array();
for ($i = 0; $i < sizeof ($a); $i++)
{
if ($a[$i] !== FALSE)
{
$b[] = $a[$i];
}
}
$a = $b;
print_r ($a);
If you don't want to reindex the array, you could use unset()
$a = array(FALSE, 2, 3, FALSE, 5, FALSE, 7, FALSE, FALSE, FALSE);
for ($i = 0; $i < sizeof ($a); $i++)
{
if ($a[$i] === FALSE)
{
unset ($a[$i]);
}
}
print_r ($a);
