用.htaccess设置PHP错误显示(转)

post by rocdk890 / 2011-12-1 16:56 Thursday linux技术

今天在网上看到使用.htaccess可以在某种程度上更改PHP的错误显示的设置,实际上相当于更改PHP.ini的参数,很是方便。将以下相应代码放到对应目录中的.htaccess文件,即可实现相应功能。

关闭错误显示:

php_flag display_startup_errors off
php_flag display_errors off
php_flag html_errors off
php_value docref_root 0
php_value docref_ext 0

只显示PHP错误:

php_flag  display_errors        on
php_flag  display_startup_errors on
php_value error_reporting        2047

其中,“2047”为要显示的错误的级别,详细表格如下:

1 E_ERROR
2 E_WARNING
4 E_PARSE
8 E_NOTICE
16 E_CORE_ERROR
32 E_CORE_WARNING
64 E_COMPILE_ERROR
128 E_COMPILE_WARNING
256 E_USER_ERROR
512 E_USER_WARNING
1024 E_USER_NOTICE
2047 E_ALL
2048 E_STRICT
4096 E_RECOVERABLE_ERROR 

要把错误保存到日志文件中,可以这样设置:

# enable PHP error logging
php_flag  log_errors on
php_value error_log  /home/path/public_html/domain/PHP_errors.log

然后,可以设置不允许访问.log文件:

# prevent access to PHP error log
<Files PHP_errors.log>
 Order allow,deny
 Deny from all
 Satisfy All
</Files>

设置错误日志的最大体积,以bytes为单位:

# general directive for



 setting max error size
log_errors_max_len integer

综合上述,.htaccess的PHP错误显示设置汇总:

# PHP error handling for production servers

# disable display of startup errors
php_flag display_startup_errors off

# disable display of all other errors
php_flag display_errors off

# disable html markup of errors
php_flag html_errors off

# enable logging of errors
php_flag log_errors on

# disable ignoring of repeat errors
php_flag ignore_repeated_errors off

# disable ignoring of unique source errors
php_flag ignore_repeated_source off

# enable logging of php memory leaks
php_flag report_memleaks on

# preserve most recent error via php_errormsg
php_flag track_errors on

# disable formatting of error reference links
php_value docref_root 0

# disable formatting of error reference links
php_value docref_ext 0

# specify path to php error log
php_value error_log /home/path/public_html/domain/PHP_errors.log

# specify recording of all php errors
php_value error_reporting 999999999

# disable max error string length
php_value log_errors_max_len 0

# protect error log by preventing public access
<Files /home/path/public_html/domain/PHP_errors.log>
 Order allow,deny
 Deny from all
 Satisfy All
</Files>

以下则是适合开发者应用的设置:

# PHP error handling for



 development servers
php_flag display_startup_errors on
php_flag display_errors on
php_flag html_errors on
php_flag log_errors on
php_flag ignore_repeated_errors off
php_flag ignore_repeated_source off
php_flag report_memleaks on
php_flag track_errors on
php_value docref_root 0
php_value docref_ext 0
php_value error_log /home/path/public_html/domain/PHP_errors.log
php_value error_reporting 999999999
php_value log_errors_max_len 0

<Files /home/path/public_html/domain/PHP_errors.log>
 Order allow,deny
 Deny from all
 Satisfy All
</Files>
