If you want to unset all empty index on an array here is a one simple way:
<?php
// an array
$arr =
('a','b','','d','','','g');
$x = 0;
foreach ($arr as $index) {
if ($index == '' || empty($index)) {
unset($arr[$x]);
} else {
$temp[] = $arr[$x];
}
$x++;
}
$arr = $temp;
foreach ($arr as $echo) {
echo $echo;
}
// output will be: abdg
?>
