Systems not using sendmail should set this directive to the sendmail wrapper/replacement their mail
system offers, if any. For example, Qmail (http://www.qmail.org/) users can normally set it to
/var/qmail/bin/sendmail.
Safe Mode Configuration Directives
safe_modeboolean
Whether to enable PHP’s safe mode. Read the Security chapter for more more information.
safe_mode_exec_dirstring
If PHP is used in safe mode, system and the other functions executing system programs refuse to
start programs that are not in this directory.
Debugger Configuration Directives
debugger.hoststring
DNS name (exp 3pod.com) or IP address of host used by the debugger.
debugger.portstring
Port number used by the debugger.
debugger.enabledboolean
Whether the debugger is enabled.
Extension Loading Directives
enable_dlboolean
This directive is really only useful in the Apache module version of PHP. You can turn dynamic
loading of PHP extensions with dl on and off per virtual server or per directory.
The main reason for turning dynamic loading off is security. With dynamic loading, it’s possible to
ignore all the safe_mode and open_basedir restrictions.
