PEAR_Dependency2::validatePackageDependency() – validatePackageDependency

Synopsis

require_once '/Dependency2.php';

array|true|PEAR_Error PEAR_Dependency2::validatePackageDependency ( array $dep , boolean $required , array $params , bool $depv1 = false )

Description

Validate a package-style dependency. Validation is performed in this sequence:

  1. If the dependency package provides an extension through the <providesextension> tag, then see if it passes the extension validation test first and return if so.

  2. If the list of packages to be installed contains a match for the dependency, use that to validate the dependency and return.

  3. If the dependency package is already installed, make sure the installed version passes the conditions.

  4. At this point, the dependency has failed. If the dependency is required, return a PEAR_Error containing the failure error message, otherwise return an array containing the error message.

Parameter

array $dep

dependency array as defined by package.xml 2.0

boolean $required

array $params

array of PEAR_Downloader_Package objects representing packages to be downloaded that can be used to validate dependencies

boolean $depv1

if TRUE, then deps on pear.php.net that fail will also check against pecl.php.net packages to accommodate extensions that have moved to pecl.php.net from pear.php.net

Throws

throws no exceptions thrown
