PHP中设置时区，记录日志文件的实现代码_php技巧

代码如下:


date_default_timezone_set('Asia/Hong_Kong'); //set time zone
set_error_handler("myHandler"); //set error handler
$chinatime = date('Y-m-d H:i:s'); //get current time
$max_size = 500000;
try
{
$content = "Hello WeiXin!";
logger2($content);
//throw new Exception("Value must be 1 or below aaaaaaaaaaaaaaaaaaa");
}
catch(Exception $e)
{
logger2("Exception Message: ".$e->getMessage());
}
//record operation log into .log file
function logger($log_content)
{
print_r(date('H:i:s')." ".$log_content."
");
$log_filename = date("Ymd").".log";
$file = fopen($log_filename ,"a+");
fwrite($file, date('H:i:s')." ".$log_content."\r\n");
fclose($file);
}
//record operation log into .log file
function logger2($log_content)
{
Global $max_size;
print_r(date('H:i:s')." ".$log_content." "."
");
$log_filename = date("Ymd").".log";
if(file_exists($log_filename) and (abs(filesize($log_filename)) > $max_size)){unlink($log_filename);sleep(1);}
file_put_contents($log_filename, date('H:i:s')." ".$log_content." "."\r\n", FILE_APPEND);
}
//error handler function
function myHandler($level, $message, $file, $line, $context)
{
logger("[ERROR] LEVEL: $level, MESSAGE: $message, FILE: $file, LINE: $line, CONTENT: $context");
die();
}
?>
