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

rpminfo(string path [, bool full  [, string &error]]): array;

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
