# RPM information extension for PHP
Retrieve RPM information from PHP code using librpm.
This extension can be considered as stable, and be used on production environement.
But be aware that if its API will probably stay stable,
some changes may occur before version 1.0.0.
----
# Sources
* Official git repository: https://git.remirepo.net/cgit/tools/php-rpminfo.git/
* Mirror on github for contributors: https://github.com/remicollet/rpminfo
# Build
You need the rpm development files (rpm-devel) version >= 4.11.3.
From the sources tree
$ phpize
$ ./configure --enable-rpminfo
$ make
$ make test
----
# Usage
## rpmvercmp
int rpmvercmp(string evr1, string evr2);
Allow to compare 2 EVR (epoch:version-release) strings. The return value is < 0 if evr1 < evr2, > 0 if evr1 > evr2, 0 if equal.
$ php -a
php > var_dump(rpmvercmp("1.0", "1.1"));
int(-1)
php > var_dump(rpmvercmp("1:1.0", "1.1"));
int(1)
## rpminfo
array rpminfo(string path [, bool full [, string &error]]);
Retrieve information from a rpm file, reading its metadata.
If given `error` will be used to store error message instead of raising a warning.
The return value is a hash table, or false if it fails.
$ php -a
php > print_r(rpminfo("tests/bidon.rpm"));
Array
(
[Name] => bidon
[Version] => 1

## rpmdbinfo
array rpmdbinfo(string path [, bool full ]);
