PHP Settings

Choose one of the following PHP handlers at Hosting Parameters >
PHP handler type taking into consideration resources consumption and
security aspects of each option:

image 76978
Performance Memory Usage Security
Apache module (Linux only)

High.

Runs as a part of the Apache web server.

Low

This handler (also known as mod_php) is the least secure
option
as all PHP scripts are executed on behalf of the
apache user. This means that all files created by PHP
scripts of any plan subscriber have the same owner
(apache) and the same permission set. Thus, there is a
theoretical possibility that some users will try to affect
files of another users or some important system files.

Note:

You can evade some security issues by turning the PHP
safe_mode option on. It disables a number of PHP functions
that bring potential security risk. Note that this may lead
to inoperability of some web apps. The safe_mode option is
considered to be obsolete and is deprecated in PHP 5.3.

ISAPI extension (Windows only, not supported since PHP
5.3
)

High.

Runs as a part of the IIS web server.

Low

The ISAPI extension can provide site isolation in case a
dedicated IIS application pool is switched on for
subscriptions. Site isolation means that sites of different
customers run their scripts independently. Thus, an error in
one PHP script does not affect the work of other scripts. In
addition, PHP scripts run on behalf of a system user associated
with a hosting account.

Note:

The ISAPI extension handler is not supported since PHP 5.3.
