pear install PHP_Archive        -> e versiune gen alpha, beta, etc si de-aia nu se instaleaza
pear install PHP_Archive-0.11.4 -> specificata versiunea exacta si instalarea va rula fara probleme
pear search pecl                -> cautare pachet pecl (gasit CodeGen_PECL)
pear install CodeGen_PECL       -> instalare varianta stable, deci fara a specifica versiunea
