htaccess怎么关闭php错误？
用.htaccess关闭PHP错误显示
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 Order allow,deny Deny from all Satisfy All
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 Order allow,deny Deny from all Satisfy All
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 Order allow,deny Deny from all Satisfy All
