httpcookie - PHP: Expire vs. Clearing a cookie -


a newbie question, bare me...

with respect creating cookies php, difference between using 'expire' parameter of 'setcookie' , setting cookie ""? in other words have cookie that's collecting information, @ point grab information , send it, , after point want destroy cookie. since (from understanding) cookies stored on client side, options expire or set "". read, 'expire' sets cookie 0, respect values; int 0 or empty string?

also question extending original questions asked here. aka if had question posted, , wanted ask similar question, edit original question , add new section or start new question (like did here)?

when set cookie stored client browsers, if set expire parameter cookie expire(deleted) after given time client computer, , if set cookie 0 cookie stay in client browser value 0.

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...
