運行時配置

這些函數(shù)的行為受 php.ini 中的設置影響。

這是配置指令的簡短說明。

filter.default string

Filter all $_GET, $_POST, $_COOKIE, $_REQUEST and $_SERVER data by this filter. Original data can be accessed through filter_input().

Accepts the name of the filter you like to use by default. See the existing filter list for the list of the filter names.

注意:

Be careful about the default flags for the default filters. You should explicitly set them to the value you want. For example, to configure the default filter to behave exactly like htmlspecialchars() you need to set them default flags to 0 as shown below.

示例 #1 Configuring the default filter to act like htmlspecialchars

filter.default = full_special_chars
filter.default_flags = 0

filter.default_flags int

Default flags to apply when the default filter is set. This is set to FILTER_FLAG_NO_ENCODE_QUOTES by default for backwards compatibility reasons. See the flag list for the list of all the flag names.
