Hi,
as your structure is always the same you could just loop through all
elements and subelements and use unset() to remove the unwanted array
elements:
foreach ($foo as $key => $value) {
foreach ($value as $subkey => $subvalue) {
// put your check logic here
if ($foo[$key][$subkey]['expires'] == '') {
unset($foo[$key][$subkey]);
}
}
}
What do you think?
