运行时配置

这些函数的行为受 php.ini 的影响。

Filesystem and Streams Configuration Options
Name Default Changeable Changelog
phar.readonly "1" PHP_INI_ALL  
phar.require_hash "1" PHP_INI_ALL  
phar.extract_list "" PHP_INI_ALL Available from phar 1.1.0 to 1.2.3, removed in 2.0.0.
phar.cache_list "" PHP_INI_SYSTEM Available from phar 2.0.0.

以下是配置选项的简要解释。

phar.readonly boolean

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.

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 enable phar.readonly in a script or disable it later. If phar.readonly is enabled in php.ini, a script may harmlessly "re-enable" the INI variable, but may not disable it.

phar.require_hash boolean

This 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 enable phar.require_hash in a script or disable it later. If phar.require_hash is enabled in php.ini, a script may harmlessly "re-enable" the INI variable, but may not disable it.

phar.extract_list string

This 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
<?php
include "phar://archive/content.php";
include 
"phar://arch2/foo.php";
?>

phar.cache_list string

This 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
