Needed a function to test if a date was valid in PHP. This function does that but it also requires an expected date format.
function isValidDate($date, $expectedFormat = 'Y-m-d'){
$t = strtotime($date);
if($date == date($expectedFormat, $t)){
return true;
}
return false;
}
Example
var_dump(isValidDate('2016-12-06'));
var_dump(isValidDate('12-06-2016'));
var_dump(isValidDate('12-06-2016', 'm-d-Y'));
var_dump(isValidDate('not a date'));
Output
bool(true)
bool(false)
bool(true)
bool(false)
