Here is an example of re-using labels in separate methods - in this example, the end: label is used
in each, with the goto condition behaving like an if/else condition:
class DateController
{
public $day, $month, $year;
public function __construct(){
$this->day = $this->setDays();
$this->month = $this->setMonths();
$this->year = $this->setYears(1901, (int)date('Y'), 'asc');
}
/**
* @param int
* @return array
*/
protected function setDays(int $default = 0){
$days = array();
for($i = 1; $i <= 31; $i++){
$day = "{$i}";
if($i<10){
$day = "0{$i}";
}
$days[$day] = $day;
}
if($default == 0){
goto end;
}
$days['default'] = $default;
end:
return $days;
}
/**
* @param string, string, string
* @return array
*/
protected function setMonths(string $type = "full", string $keyType =
"numeric", string $default = ''){
$keys = array(
'numeric' => array(
"01", "02", "03", "04", "05",
"06", "07", "08", "09", "10", "11",
"12"
),
'full' => array(
"January", "February", "March", "April",
"May", "June", "July",
"August", "September", "October",
"November", "December"
),
'short' => array(
"Jan", "Feb", "Mar", "Apr", "May",
"Jun",
"Jul", "Aug", "Sep", "Oct", "Nov",
"Dec"
)
);
$months = array();
$index = 0;
foreach($keys[$keyType] as $primaryKey){
$months[$primaryKey] = $keys[$type][$index];
$index++;
}
if($default = ''){
goto end;
}
$months['default'] = $default;
end:
return $months;
}
/**
* @param int, int, string
* @return array
*/
protected function setYears(int $start = 1977, int $end = 2017, $order = "asc"){
$years = array();
if($order == "asc"){
for($i = $start; $i <= $end; $i++){
$years["{$i}"] = $i;
}
goto end;
}
for($i = $end; $i >= $start; $i--){
$years["{$i}"] = $i;
}
end:
return $years;
}
}
