CSS, HTML bug

查這個function a 那裡會被使用

function a(){

echo ‘<pre>’;

print_r(debug_backtrace(true));

echo ‘</pre>’;

}

PHP debug_backtrace, find the call function location, php

主要防止一些javascript執行(onchange, onclick)的時候,沒有回應
<input type=”text” autocomplete off />
這樣就能取消text box history

HTML HTML, javascript, textbox

Perl	time
PHP	time()
Ruby	Time.now (or Time.new). To display the epoch: Time.now.to_i
Python	import time first, then time.time()
Java	long epoch = System.currentTimeMillis()/1000;
Microsoft .NET C#	epoch = (DateTime.Now.ToUniversalTime().Ticks - 621355968000000000) / 10000000;
VBScript/ASP	DateDiff("s", "01/01/1970 00:00:00", Now())
Erlang	calendar:datetime_to_gregorian_seconds(calendar:now_to_universal_time( now()))-719528*24*3600.
MySQL	SELECT unix_timestamp(now())
PostgreSQL	SELECT extract(epoch FROM now());
Oracle PL/SQL	SELECT (SYSDATE - TO_DATE('01-01-1970 00:00:00', 'DD-MM-YYYY HH24:MI:SS')) * 24 * 60 * 60 FROM DUAL
SQL Server	SELECT DATEDIFF(s, '1970-01-01 00:00:00', GETUTCDATE())
JavaScript	Math.round(new Date().getTime()/1000.0) getTime() returns time in milliseconds.
Unix/Linux	date +%s
Other OS’s	Command line: perl -e "print time" (If Perl is installed on your system)
