Pothuajse menj\u00ebher\u00eb zbuluam se Go na lejon t\u00eb krijojm\u00eb aplikacione m\u00eb t\u00eb m\u00ebdha me nj\u00eb rritje t\u00eb performanc\u00ebs deri n\u00eb 40 her\u00eb.

Mjedisi juaj i p\u00ebrditsh\u00ebm i zhvillimit PHP<\/h3>\n

\nPara se t\u00eb flasim se si Go mund ta zgjoj\u00eb modelin e \u2018vdekjes\u2019 s\u00eb PHP, le t\u00eb shqyrtojm\u00eb mjedisin tuaj standard t\u00eb zhvillimit PHP.<\/p>\n

N\u00eb shumic\u00ebn e rasteve, ju e \u0437\u0430\u043f\u0443\u0441\u043a\u0430\u0442\u0435 aplikacionin me nj\u00eb kombinim t\u00eb serverit web nginx dhe serverit PHP-FPM. I pari sh\u00ebrben skedar\u00ebt statik\u00eb dhe redirection k\u00ebrkesat specifike te PHP-FPM, nd\u00ebrsa vet\u00eb PHP-FPM ekzekuton kodin PHP. Ndoshta ju po p\u00ebrdorni nj\u00eb kombinim m\u00eb pak t\u00eb njohur t\u00eb Apache dhe mod_php. Por ndon\u00ebse ai funksionon pak ndryshe, parimet jan\u00eb t\u00eb nj\u00ebjta.<\/p>\n

Le t\u00eb shohim se si PHP-FPM ekzekuton kodin e aplikacionit. Kur arrin nj\u00eb k\u00ebrkes\u00eb, PHP-FPM inicializon nj\u00eb proces PHP dyt\u00ebsor dhe detajet e k\u00ebrkes\u00ebs i kalon si pjes\u00eb e gjendjes s\u00eb tij (_GET, _POST, _SERVER etj.). <\/p>\n

Gjat\u00eb ekzekutimit t\u00eb skriptit PHP, gjendja nuk mund t\u00eb ndryshohet, prandaj mund t\u00eb merrni nj\u00eb set t\u00eb ri t\u00eb t\u00eb dh\u00ebnave hyr\u00ebse vet\u00ebm n\u00eb nj\u00eb m\u00ebnyr\u00eb: duke e pastruar memorien e procesit dhe e inicializoni at\u00eb p\u00ebrs\u00ebri.<\/p>\n

Ky model ekzekutimi ka shum\u00eb p\u00ebrfitime. Nuk keni nevoj\u00eb t\u00eb shqet\u00ebsoheni shum\u00eb p\u00ebr konsumimin e memories, t\u00eb gjith\u00eb proceset jan\u00eb plot\u00ebsisht t\u00eb izoluar, dhe n\u00ebse ndonj\u00eb prej tyre \"vdes\", do t\u00eb rinovohet automatikisht dhe kjo nuk do t\u00eb ndikoj\u00eb n\u00eb proceset e tjera. Por ka dhe disavantazhe lidhur me k\u00ebt\u00eb qasje q\u00eb shprehen gjat\u00eb p\u00ebrpjekjeve p\u00ebr t\u00eb shkall\u00ebzuar aplikacionin.<\/p>\n

\nN\u00ebse jeni duke u marr\u00eb me zhvillimin profesional n\u00eb PHP, at\u00ebher\u00eb e dini se nga duhet t\u00eb filloni nj\u00eb projekt t\u00eb ri - nga zgjedhja e nj\u00eb kuadri.
