Laufzeit-Konfiguration
Das Verhalten dieser Funktionen wird durch Einstellungen in der php.ini beeinflusst.
Name | Standard | Veränderbar | Changelog |
---|---|---|---|
phar.readonly | "1" | PHP_INI_ALL | |
phar.require_hash | "1" | PHP_INI_ALL | |
phar.cache_list | "" | PHP_INI_SYSTEM |
Hier eine kurze Erklärung der Konfigurationsoptionen:
-
phar.readonly
bool -
This option disables creation or modification of Phar archives using the
phar
stream or Phar 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.Hinweis:
This setting can only be unset in php.ini due to security reasons. If
phar.readonly
is disabled in php.ini, the user may enablephar.readonly
in a script or disable it later. Ifphar.readonly
is enabled in php.ini, a script may harmlessly "re-enable" the INI variable, but may not disable it. -
phar.require_hash
bool -
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.
Hinweis:
This setting can only be unset in php.ini. If
phar.require_hash
is disabled in php.ini, the user may enablephar.require_hash
in a script or disable it later. Ifphar.require_hash
is enabled in php.ini, a script may harmlessly "re-enable" the INI variable, but may not disable it.This setting does not affect reading plain tar files with the PharData class.
Achtungphar.require_hash
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. -
phar.cache_list
string -
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.
Beispiel #1 phar.cache_list usage example
in php.ini (windows): phar.cache_list =C:\path\to\phar1.phar;C:\path\to\phar2.phar in php.ini (unix): phar.cache_list =/path/to/phar1.phar:/path/to/phar2.phar
