这是配置指令的简短说明。
phar.readonly
boolThis 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.Note:
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
boolThis option will force all opened Phar archives to contain some kind of signature (currently MD5, SHA1, SHA256 and SHA512 are supported), and will refuse to process any Phar archive that does not contain a signature.
Note:
This setting can only be unset in php.ini due to security reasons. 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.
phar.extract_list
stringThis INI setting has been removed as of phar 2.0.0
Allows mappings from a full path to a phar archive or its alias to the location of its extracted files. The format of the parameter is
name=archive,name2=archive2
. This allows extraction of phar files to disk, and allows phar to act as a kind of mapper to extracted disk files. This is often done for performance reasons, or to assist with debugging a phar.Example #1 phar.extract_list usage example
in php.ini:phar.extract_list = archive=/full/path/to/archive/,arch2=/full/path/to/arch2<?phpinclude "phar://archive/content.php";include "phar://arch2/foo.php";?>
phar.cache_list
stringThis INI setting was added in phar 2.0.0
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.
Example #2 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
