Gjat\u00eb dhjet\u00eb viteve t\u00eb fundit, ne krijuam aplikacione p\u00ebr kompani nga lista Fortune 500<\/a><\/noindex>, dhe p\u00ebr biznese me nj\u00eb audienc\u00eb prej m\u00eb pak se 500 p\u00ebrdoruesve.

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.

Ne do t\u00eb tregojm\u00eb se si kombinimi Go dhe PHP ndihmon n\u00eb zgjidhjen e problemeve reale t\u00eb zhvillimit dhe si u b\u00eb nj\u00eb mjet q\u00eb na ndihmon t\u00eb heqim dor\u00eb nga disa nga problemet e lidhura me modelin e 'vdekjes' s\u00eb PHP<\/a><\/noindex>.<\/p>\n

Mjedisi juaj p\u00ebr zhvillim PHP \u00e7do dit\u00eb<\/h3>\n

\nPara se treguar se si, me ndihm\u00ebn e Go, mund ta ringjallni modelin e \"vdekjes\" s\u00eb PHP-s\u00eb, le t\u00eb shqyrtojm\u00eb ambientin tuaj standard t\u00eb zhvillimit PHP.<\/p>\n

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

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

Gjendja nuk mund t\u00eb ndryshoj\u00eb gjat\u00eb ekzekutimit t\u00eb skenarit PHP, prandaj nj\u00eb grup t\u00eb ri t\u00eb t\u00eb dh\u00ebnave hyr\u00ebse mund t\u00eb merret vet\u00ebm n\u00eb nj\u00eb m\u00ebnyr\u00eb: duke pastruar memorien e procesit dhe duke e inicializuar at\u00eb p\u00ebrs\u00ebri.<\/p>\n

Ky model ka shum\u00eb p\u00ebrfitime. Nuk duhet t\u00eb shqet\u00ebsoheni shum\u00eb p\u00ebr konsumin e memories, t\u00eb gjitha proceset jan\u00eb t\u00eb izoluara plot\u00ebsisht, dhe n\u00ebse nj\u00ebri prej tyre \"vdes\", ai do t\u00eb rikrijohet automatikisht pa prekur proceset e tjera. Por ky qasje ka edhe disavantazhe, q\u00eb shfaqen kur p\u00ebrpiqeni t\u00eb shkall\u00ebzoni aplikacionin.<\/p>\n

Disavantazhet dhe efikasiteti i ul\u00ebt i nj\u00eb ambienti t\u00eb zakonsh\u00ebm PHP<\/h3>\n

\nN\u00ebse jeni t\u00eb angazhuar n\u00eb zhvillimin profesional me PHP, e dini nga duhet t\u00eb filloni nj\u00eb projekt t\u00eb ri \u2014 nga zgjedhja e nj\u00eb framework-u. Ai p\u00ebrb\u00ebn biblioteka p\u00ebr shtimin e var\u00ebsive, ORM, p\u00ebrkthime dhe shabllone. Dhe, sigurisht, t\u00eb gjitha t\u00eb dh\u00ebnat e hyrjes nga p\u00ebrdoruesit mund t\u00eb vendosen leht\u00ebsisht n\u00eb nj\u00eb objekt (Symfony\/HttpFoundation ose PSR-7).

Por m\u00eb e keqja \u00ebsht\u00eb se pas kryerjes s\u00eb \u00e7do detyre, do t\u00eb duhet t\u00eb rinisni nga fillimi: t\u00eb gjith\u00eb kodin e sapo iniciuar b\u00ebhet i padobish\u00ebm, me t\u00eb cilin nuk mund t\u00eb p\u00ebrpunoni nj\u00eb tjet\u00ebr k\u00ebrkes\u00eb.
