We do not xi:include core INI settings, since we want to keep alphabetic sort order (well, roughly at least). We do add xi:fallback elements to all xi:includes, just in case.

This option disables creation or modification of Phar archives
|
|
using the <literal>phar</literal> stream or <classname>Phar</classname>
|
|
object's write support. This setting should always be enabled on
|
|
production machines, as the phar extension's convenient write support
|
|
could allow straightforward creation of a php-based virus when coupled
|
|
with other common security vulnerabilities.

<note>

<para>
|
|
This setting can only be unset in php.ini due to security reasons.
|
|
If <literal>phar.readonly</literal> is disabled in php.ini, the
|
|
user may enable <literal>phar.readonly</literal> in a script
|
|
or disable it later. If <literal>phar.readonly</literal> is
|
|
enabled in php.ini, a script may harmlessly "re-enable"
|
|
the INI variable, but may not disable it.

This option will force all opened Phar archives to contain some

kind of signature (currently MD5, SHA1, SHA256, SHA512 and OpenSSL are supported), and will

refuse to process any Phar archive that does not contain a signature.

<caution>
|
|
<simpara>
|
|
<literal>phar.require_hash</literal> does not provide any security per se,
|
|
it is merely a measure against running accidentially corrupted Phar archives,
|
|
because anyone who would be able to tamper with the Phar could easily fix
|
|
the signature afterwards.

Allows mapping phar archives to be pre-parsed at web server startup,
|
|
providing a performance improvement that brings running files out of a
|
|
phar archive very close to the speed of running those files from a
|
|
traditional disk-based installation.
