运行时配置

这些函数的行为受 php.ini 中的设置影响。

**IMAP 配置选项**
名字	默认	可修改范围	更新日志
imap.enable_insecure_rsh	"0"	PHP_INI_SYSTEM	Available as of PHP 7.1.25, 7.2.13 and 7.3.0. Formerly, it was implicitly enabled.

有关 PHP_INI_* 样式的更多详情与定义，见配置可被设定范围。

这是配置指令的简短说明。

imap.enable_insecure_rsh boolean: Establishing a connection to a server may invoke rsh or ssh commands, unless this php.ini option is disabled.

Warning
Neither PHP nor the IMAP library filter mailbox names before passing them to rsh or ssh commands, thus passing untrusted data to this function without disabling this php.ini option is insecure.
