轉：PHP - .htaccess設置顯示PHP錯誤

使用.htaccess能夠在某種程度上更改PHP的錯誤顯示的設置，實際上，至關於更改PHP.ini的參數，非常方便。

將如下相應代碼放到對應目錄中的.htaccess文件，便可實現相應功能。

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

只顯示PHP錯誤 ：

php_flag  display_errors        on
php_flag  display_startup_errors on
php_value error_reporting        2047

其中，「2047」爲要顯示的錯誤的級別，詳細表格以下：

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 

要把錯誤保存到日誌文件中 ，能夠這樣設置：

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

而後，能夠設置不容許訪問.log文件 ：

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

設置錯誤日誌的最大致積 ，以bytes爲單位：

# general directive for




 setting max error size
log_errors_max_len integer

綜合上述，.htaccess的PHP錯誤顯示設置彙總 ：

# 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>

如下則是適合開發者應用的設置：

# 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>
