php - Convert Date and Time strings to DateTime -


i'm trying convert date , time datetime format using php:

$matches_date = null; preg_match('/\[(.*[^]])\]/', $line_text, $matches_date); print "date: ".$matches_date[1]."<br>";  $matches_time = null; preg_match('/\(([^)]*)\)/', $line_text, $matches_time); print "time: ".$matches_time[1]."<br>";  $release_date = date("y-m-d h:i:s", strtotime($matches_date[1] + " " + $matches_time[1])); print "datetime: ".$release_date."<br>";

output:

date: 2013-01-30

time: 13:00:00

datetime: 2013-05-10 20:26:00

datetime incorrect. how fix it? tried many variations none worked.

you using wrong operator concatenate. . not +

$release_date = date("y-m-d h:i:s", strtotime($matches_date[1] . " " . $matches_time[1]));

linux - xterm copying to CLIPBOARD using copy-selection causes automatic updating of CLIPBOARD upon mouse selection -

i've tried various ways coerce xterm (versions 285 , 292) copy selection clipboard clipboard whenever press ctrl-shift-c. promising way far has been, in ~/.xresources, put this: xterm*vt100.translations: #override \ ctrl shift <keypress> c: copy-selection(clipboard) \n\ ctrl shift <keypress> v: insert-selection(clipboard) ctrl-shift-v works perfectly, copying has nuance... if restart xterm, highlighting text puts things in primary clipboard; expected, proper, default behavior. if hit ctrl-shift-c, copies current selection clipboard clipboard. the bug, however, if highlight text after first time pressed ctrl-shift-c, you'll see highlighting copies both primary and clipboard. cannot figure out how stop xterm updating clipboard upon selection... , doesn't make sense me in first place. i said, @ specific point in time, copy selection clipboard... yet starts updating automatically upon selection after doing once... anyone have workaround...
