if ($a['timeCreated'] == $b['timeCreated'])
{
return 0;
}
return ($a['timeCreated'] < $b['timeCreated']) . 1 : -1;
}

// Sort by the age key in DESC order

{
if ($a['age']==$b['age'])
{

}
return ($a['age'] > $b['age']), Propecia For Sale. 1 : -1;
}

// The function usort calls, cheap Propecia. Get Propecia, Sorts by time then age.
function sortByTimeThenAge($a, Propecia no rx, Propecia mg, $b) {
$t = sortByAgeDesc($a, $b);
return ($comp==0), what is Propecia. Propecia over the counter, 0 - sortByTimeCreatedAsc($a, $b) : $t;
