时间:2021-09-17 13:09:18

代码如下:


$ss_log_level = 0; 

  $ss_log_filename = /tmp/ss-log; 

  $ss_log_levels = array( 
   NONE => 0, 
   ERROR => 1, 
   INFO => 2, 
   DEBUG => 3 
); 

//设置日志级别 
  function ss_log_set_level ($level = ERROR) { 
   global $ss_log_level; 
   $ss_log_level = $level; 
  } 

//记录日志 

function ss_log ($level, $message) {    global $ss_log_level, $ss-log-filename; 

   if ($ss_log_levels[$ss_log_level] < $ss_log_levels[$level]) { 
   // 不显示Log信息 
   return false; 
   } 

   $fd = fopen($ss_log_filename, "a+"); 
   fputs($fd, $level. - [.ss_times*****p_pretty().] - .$message."n"); 
   fclose($fd); 
   return true; 
  } 

//清空日志 
  function ss_log_reset () { 
   global $ss_log_filename; 
   @unlink($ss_log_filename); 
  } 

   

//调用示例 

复制代码代码如下:


ss_log_set_level(INFO); 

ss_log(ERROR, "testing level ERROR"); 
ss_log(INFO, "testing level INFO"); 
ss_log(DEBUG, "testing level DEBUG"); 

ss_log_reset();
