If formatting date in x-axis in Javascript,

xAxis: {
                type: 'datetime',
                dateTimeLabelFormats: { // don't display the dummy year
                    month: '%e. %b',
                    year: '%b'
                }
            }, 

How can I equate it into php??

'xAxis' => array(
	'type'=>'datetime',
	'dateTimeLabelFormats'=> array( // don't display the dummy year
	    'month' => '%e %b',
	    'year' => '%y'
	),

This will show x-axis like 23:59:57
