本文实例讲述了php实现的简单日志写入函数。分享给大家供大家参考。具体实现方法如下：
function log( $logthis ){
file_put_contents('logfile.log', date("Y-m-d H:i:s"). " " . $logthis. "\r\n", FILE_APPEND | LOCK_EX);
}
// use \r\n for new line on windows, just \n on linux
// PHP_EOL cross platform solution for new line
// // so better to use this
function log( $logthis ){
file_put_contents('logfile.log', date("Y-m-d H:i:s"). " " . $logthis.PHP_EOL, FILE_APPEND | LOCK_EX);
}
