＄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) {

}

//记录日志

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

// 不显示Log信息

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(INFO, "testing level INFO");

ss_log(DEBUG, "testing level DEBUG");

ss_log_reset();
