在php中,可以用.htaccess檔案去設定日誌的顯示層級,比如

關閉錯誤顯示：

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隻顯示PHP錯誤：

php_flag  display_errors        on

php_flag  display_startup_errors on

php_value error_reporting        2047其中，“2047”為要顯示的錯誤的層級，詳細表格如下：

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 要把錯誤儲存到記錄檔中，可以這樣設定：

# enable PHP error logging

php_flag  log_errors on

php_value error_log  /home/path/public_html/domain/PHP_errors.log然後，可以設定不允許訪問.log檔案：

# prevent access to PHP error log

<Files PHP_errors.log>

Order allow,deny

Deny from all

Satisfy All

</Files>設定錯誤記錄檔的最大體積，以bytes為單位：

# general directive for setting max error size

log_errors_max_len integer綜合上述，.htaccess的PHP錯誤顯示設定匯總：

# 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>以下則是適合開發人員應用的設定：

# 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>
