将PHP date（）样式的dateFormat转换为等效的jQuery UI datepicker字符串

Posted 2021-02-25

This is a simple bit of code that allows you to do a write once date format in a php style date() format and convert it to be used by datepicker jQuery UI widget. It returns the converted string. Nothing fancy here, but a time saver for the future. Could use improvement such as error handling for common PHP dateFormat string values that do not have an equivalent UI portion. Potentially make this a two way conversion. Add more available options.

function dateStringToDatepickerFormat($dateString)
{
	$pattern = array(
 
		//day
		'd',		//day of the month
		'j',		//3 letter name of the day
		'l',		//full name of the day
		'z',		//day of the year
 
		//month
		'F',		//Month name full
		'M',		//Month name short
		'n',		//numeric month no leading zeros
		'm',		//numeric month leading zeros
 
		//year
		'Y', 		//full numeric year
		'y'		//numeric year: 2 digit
	);
	$replace = array(
		'dd','d','DD','o',
		'MM','M','m','mm',
		'yy','y'
	);
	foreach($pattern as &$p)
	{
		$p = '/'.$p.'/';
	}
	return preg_replace($pattern,$replace,$dateString);
}
