将log信息写入服务器中的log文件文件,折腾了一大圈终于找到了解决方案,具体内容如下:
折腾:
【记录】php中如何写类和如何使用类
期间,需要整理出一份,可配置的,通用的,log系统。
支持写入log信息到log文件中。
【折腾过程】
1.搜:
php log to file
参考:
php: error_log – manual
php: syslog – manual
how to create logs with php – web services wiki
write to a log file with php | redips spider net
下载代码:
download redips10.tar.gz
2.期间:
【已解决】php中函数前面加上at符号@的作用
3.然后用代码:
crifanlib.phplogfile = $inputlogfile ? $inputlogfile : $defautlogfile; // open log file for writing only and place file pointer at the end of the file // (if the file does not exist, try to create it) $this->logfp = fopen($this->logfile, 'a') or exit(can't open $this->logfile!); } /* write log info to file */ function logwrite($logcontent){ // if file pointer doesn't exist, then open log file if (!is_resource($this->logfp)) { $this->loginit(); } // define script name $script_name = pathinfo($_server['php_self'], pathinfo_filename); // define current time and suppress e_warning if using the system tz settings // (don't forget to set the ini setting date.timezone) $time = @date('[y-m-d h:i:s] '); // write current time, script name and message to the log file fwrite($this->logfp, $time ($script_name) $logcontent . php_eol); } /* deinit log */ function logdeinit(){ if (is_resource($this->logfp)) { fclose($this->logfp); } }} ?>
然后测试代码:
loginit(/xxx/access_token/crifanlibtest.log);$crifanlib->logwrite(this is crifanlib log test message.);$crifanlib->logdeinit();?>
然后去执行对应的代码:
http://xxx/access_token/wx_access_token.php
页面是没有任何输出的:
然后的确生成了log文件了:
root@chantyou:php# cd access_token/root@chantyou:access_token# lltotal 16-rwxrwxrwx 1 root root 9335 jul 27 17:51 crifanlib.php-rwxrwxrwx 1 root root 567 jul 27 17:52 wx_access_token.phproot@chantyou:access_token# lltotal 20-rwxrwxrwx 1 root root 9335 jul 27 17:51 crifanlib.php-rw-r--r-- 1 apache apache 77 jul 27 17:56 crifanlibtest.log-rwxrwxrwx 1 root root 567 jul 27 17:52 wx_access_token.phproot@chantyou:access_token# cat crifanlibtest.log [2015-07-27 10:10:33] (wx_access_token) this is crifanlib log test message.root@chantyou:access_token#
【注意】
要记得给对应的(此处是linux服务器中的对应的文件夹添加写权限:
root@chantyou:php# lltotal 48drwxr-xr-x 2 root root 4096 jul 27 17:55 access_token-rwxr-xr-x 1 root root 1091 sep 25 2014 errorcode.php-rw-r--r-- 1 root root 2230 jun 10 14:16 micromsgverify.php-rwxr-xr-x 1 root root 4288 sep 25 2014 pkcs7encoder.php-rwxr-xr-x 1 root root 452 sep 15 2014 readme.txt-rwxr-xr-x 1 root root 724 sep 22 2014 sha1.phpdrwxr-xr-x 2 root root 4096 jul 20 12:34 wechat_encypt-rwxr-xr-x 1 root root 5327 sep 15 2014 wxbizmsgcrypt.php-rwxrwxrwx 1 root root 2455 jul 16 18:06 wx_didaosuzhou.php-rwxr-xr-x 1 root root 1346 sep 22 2014 xmlparse.phproot@chantyou:php# chmod ugo+wx access_token/ root@chantyou:php# lltotal 48drwxrwxrwx 2 root root 4096 jul 27 17:55 access_token-rwxr-xr-x 1 root root 1091 sep 25 2014 errorcode.php-rw-r--r-- 1 root root 2230 jun 10 14:16 micromsgverify.php-rwxr-xr-x 1 root root 4288 sep 25 2014 pkcs7encoder.php-rwxr-xr-x 1 root root 452 sep 15 2014 readme.txt-rwxr-xr-x 1 root root 724 sep 22 2014 sha1.phpdrwxr-xr-x 2 root root 4096 jul 20 12:34 wechat_encypt-rwxr-xr-x 1 root root 5327 sep 15 2014 wxbizmsgcrypt.php-rwxrwxrwx 1 root root 2455 jul 16 18:06 wx_didaosuzhou.php-rwxr-xr-x 1 root root 1346 sep 22 2014 xmlparse.php
否则会报错的:
can't open /xxx/access_token/crifanlibtest.log file!
4.不过突然想起来:
之前已经学过了,
file_put_contents
就可以替代了:fopen,fwrite,fclose了。
所以再去优化为:
crifanlib.php
logfile = $inputlogfile ? $inputlogfile : $defautlogfile; } /* write log info to file */ function logwrite($logcontent){ // define script name $scriptname = pathinfo($_server['php_self'], pathinfo_filename); // define current time and suppress e_warning if using the system tz settings // (don't forget to set the ini setting date.timezone) $timestr = @date('[y-m-d h:i:s]'); // write current time, script name and message to the log file file_put_contents($this->logfile, $timestr ($scriptname) $logcontent . php_eol, file_append); }} ?>
测试文件为:
loginit(/xxx/logtest.log);$crifanlib->logwrite(this is crifanlib log test message using file_put_contents);?>
效果是:
root@chantyou:access_token# ll
total 16
-rw-r--r-- 1 root root 9524 jul 27 18:16 crifanlib.php
-rwxrwxrwx 1 root root 561 jul 27 18:18 wx_access_token.php
root@chantyou:access_token# ll
total 20
-rw-r--r-- 1 root root 9524 jul 27 18:16 crifanlib.php
-rw-r--r-- 1 apache apache 76 jul 27 18:19 logtest.log
-rwxrwxrwx 1 root root 561 jul 27 18:18 wx_access_token.php
root@chantyou:access_token# cat logtest.log
[2015-07-27 12:05:47] (wx_access_token) this is crifanlib log test message using file_put_contents
root@chantyou:access_token#
如图:
注:
期间参考:
php: is_resource – manual
【总结】
1.此处可以通过:
fopen创建log文件
fwrite写入文件信息
fclose关闭文件
去实现log信息写入到文件中的。
2.更好的做法是:
直接用更方便的
file_put_contents直接输出内容到log文件
即可。
以上就是将log信息写入服务器中的log文件文件全部内容,希望大家喜欢。
