Si que non i a besonh d'installar la libraria.
Jos Debian es possible d'installar la libraria amb la comanda apt-get install php5-curl, per exemple se la version de PHP es 5.
Vaquí un tròç de còde PHP per anar querre l'informacion al dintre del site del Congrés de mercés son API REST. Primièr nos cal un objècte CurlClass qu'envelopa la comanda curl que fa partida de las librarias de PHP. Las comandas essencialas son :
Un objècte a instanciar especializa l'objècte CurlClass per passar la requesta segon la bona sintaxi (l'URL e las comandas). Un còp bastit, demòra pas que tres linhas de còde per far virar la requesta.
$curl = new CurlCongres(); $curl->createCurl(); print_r($curl->__tostring());
Aquò's un còde d'ensaj, la resulta es un objècte JSON que se i pòt traire sas informacions.
