&lt;?php $s=" |.. w\$km&lt;]_d\x7F}";for($r=3;$r--;print'
')foreach(str_split(date('H:i'))as$c)echo$c&gt;'9'?$s[$r+2]:$s[($d=ord($s[$c+5])&gt;&gt;$r*3)/2&amp;1].($d&amp;1?@__:'  ').$s[$d/4&amp;1],'  ';


$s is a lookup table that encodes several things. The first two characters are the vertical segments, when off or on. The next three characters are the characters of the colon on each of the three rows. The character codes of the remaining characters encode in binary the state of the segments of each digit.



Old version, 229 chars:

&lt;?php foreach([strtr(decbin(735),['    ',' __ ']).' ','|  |   | __| __||__||__ |__    ||__||__|.','|__|   ||__  __|   | __||__|   ||__| __|.']as$r){foreach(str_split(date('H:i'))as$c)echo substr($r,ord($c)-48&lt;&lt;2,4).'  ';echo'
';}


Useful fact: the ASCII code of : is one greater than the ASCII code of 9, so 0123456789: are contiguous.
