He aha ka PHP programming?

The PHP Programmiersprache has emerged as one of the most popular and widely used languages to build websites. He wikiwiki a maʻalahi ke aʻo ʻana i ka Object-Orientierte Programmiersprache i hoʻohana ʻia i nā ʻano noi like ʻole., mai nā ʻōnaehana hale kūʻai a me nā ʻōnaehana hoʻokele maʻiʻo i ka hoʻokipa pūnaewele. Inā ʻoe e ʻimi e aʻo hou e pili ana i ka PHP, heluhelu mai.

ʻŌlelo hoʻonohonoho hoʻonohonoho mea

PHP has evolved into an ObjectOrientated programming language, he huaolelo ke ano “hoʻolālā mea.” ʻOiai ʻo PHP 4 ua loaʻa kekahi ObjectOrientation, ka hoʻokuʻu PHP hou loa, PHP 5, ua piha ObjectOriented. ʻO ia hoʻi, ʻaʻole e haʻalele hou ana ʻo PHP ma hope o nā ʻōlelo papahana ʻē aʻe i ka wā e pili ana i ka hoʻolālā ʻana i nā mea. Aia kekahi mau kuhi hewa, akā naʻe, e mau nei no.

Hoʻohana nā ʻōlelo hoʻolālā i nā mea i nā papa e hoʻonohonoho i ka ʻikepili ma ke ʻano kūpono. Hōʻike kēlā me kēia papa i kahi ʻano ʻikepili. Aia nā papa i nā ʻano a me nā hiʻohiʻona a hoʻohana ʻia i kumu no ka launa pū ʻana. Hoʻohana ʻia nā papa e hoʻohālike i nā ʻano ʻikepili paʻakikī. He ʻokoʻa i nā ʻikepili maʻalahi i hoʻohana ʻia i ka code PHP kuʻuna, ʻAe ʻo OOP i kahi hierarchy logical o ka ʻikepili.

He ala maikaʻi loa ia e hoʻomaʻamaʻa i kāu code e mālama ai. Hiki iā ʻoe ke hoʻohana hou i ke code a hoʻohana hou i nā ʻāpana me ka hopohopo ʻole e kūʻē kekahi i kekahi. He mea maikaʻi loa kēia i ka wā e hana ai i ka nui, nā noi paʻakikī. ʻO ka hoʻohana ʻana i ka polokalamu Object-Oriented e maʻalahi ka mālama a hoʻohana hou i ka code.

Nui nā pōmaikaʻi o ka hoʻolālā ʻana i nā mea. Hiki iā ʻoe ke hoʻoponopono i nā pilikia paʻakikī ma ka lawe ʻana i kahi pae hou o ka abstraction i kāu code. Hana ʻia kēia ma ka hoʻokaʻawale ʻana i nā code i nā papa ʻokoʻa. Loaʻa i kēia mau papa nā ʻano ʻikepili kikoʻī a me nā ʻano i hiki ke hoʻololi a hoʻohana hou ʻia no nā kumu like ʻole.

He ala maikaʻi loa ka hoʻolālā ʻana i nā mea e hana ai i nā noi pūnaewele ikaika. He ʻoi aku ka maʻalahi ma mua o HTML, a he maʻalahi ke aʻo a hoʻohana. He koho maikaʻi nō hoʻi no ke kūkulu ʻana i nā polokalamu ʻoihana pilikino. Ma waho aʻe o ka hana ʻana i kahi pūnaewele dynamic, Hāʻawi ka PHP iā ʻoe e hana i nā polokalamu maʻamau i kū hoʻokahi i kāu hui.

Hiki iā ʻoe ke hoʻokaʻawale i kāu mau papa mai kekahi i kekahi. Ma kahi o hoʻokahi papa nui a me nā papa liʻiliʻi, hiki iā ʻoe ke loaʻa nā papa ʻokoʻa a me nā ʻano hana no kēlā me kēia papa. Ma ka hopena, ʻoi aku ka maʻalahi o kāu code, ʻoi aku ka hoʻonohonoho ʻana, a ʻoi aku ka maikaʻi. Hiki iā ʻoe ke hoʻokele maikaʻi i kāu code.

ʻO ke ala maikaʻi loa e ʻimi ai i kahi ʻōlelo hoʻolālā kūikawā kūpono iā ʻoe, ʻo ia ke kūkākūkā me kāu pūnaewele. Inā loaʻa iā ʻoe kahi kēkelē ma kahi kahua e pili ana i ka ʻepekema kamepiula, Hiki iā ʻoe ke nīnau i kāu mau hoa hana i ka ʻōlelo hoʻolālā a lākou e hoʻohana ai. Hiki iā lākou ke hāʻawi iā ʻoe i kekahi mau ʻōlelo aʻoaʻo a i ʻole e haʻi iā ʻoe e pili ana i nā ʻōlelo papahana kūikawā hiki iā ʻoe ke aʻo iā ʻoe iho. Hiki iā ʻoe ke ʻimi i nā kūlana ma Stellenanzeigen e ʻike i nā ʻōlelo a me nā hui ʻana i makemake ʻia.

Ma waho aʻe o PHP, hiki nō hoʻi iā ʻoe ke hoʻohana i nā ʻōlelo papahana ʻē aʻe. ʻO Ruby kekahi o lākou. Eia naʻe, he mau hemahema ko keia olelo. ʻo kahi laʻana, He lohi loa ʻo Ruby. Hoʻohana ʻo Ruby i nā ʻano ʻikepili ikaika.

PHP is a highly flexible and powerful programming language that supports multiple databases and real-time monitoring. ʻO kāna mau hiʻohiʻona pili i ka datenbank he koho maikaʻi loa ia no ka hoʻomohala pūnaewele. He kumu hāmama ka PHP, ʻo ia hoʻi, hiki i kekahi ke hoʻoiho a hoʻohana me ka manuahi. Aia kekahi kaiaulu PHP nui e kaʻana like i nā ʻōlelo kōkua a me ka ʻike.

Hoʻohana nui ʻia ka PHP ma ka ʻoihana hoʻomohala pūnaewele. He kiʻekiʻe kona kaulana, a hoʻohana pinepine ʻia i ke code ma hope o kekahi o nā pūnaewele nui loa ma ka Pūnaewele. Kahi mea hou aʻe, He manuahi ka PHP a ke hoʻomaikaʻi mau ʻia nei. ʻOiai, aia kekahi mau hemahema, me kona palena scalability a me unpredictability, He koho paʻa ka PHP.

Loaʻa iā PHP kahi syntax maʻalahi, e maʻalahi i nā polokalamu polokalamu ke hoʻololi. Hoʻokomo pū ʻia i loko o HTML, ʻo ia hoʻi, ua kākau maikaʻi ʻia ke code. He ʻōlelo hoʻolālā ikaika ʻo PHP a hiki ke hoʻoponopono i nā pilikia paʻakikī, ka hoʻomaikaʻi ʻana i ka ʻoihana hoʻokūkū. E like me ia, he mea nui e aʻo a hoʻomaopopo i ka ʻōlelo i mea e hana ai i nā polokalamu pūnaewele pono loa a me nā lako polokalamu.

He mea nui nō hoʻi e paʻa i ka wā e kūkulu ai i nā polokalamu pūnaewele. Ua ʻike ʻia kahi haʻawina hou 86% o nā polokalamu PHP i loaʻa kahi nāwaliwali i kapa ʻia ʻo XSS. ʻAʻole kēia ka hopena o ka honua, ʻoiai ua hana ke kaiāulu PHP i nā hana he nui i mea e palekana ai ka PHP. Eia naʻe, ʻAʻole paʻa loa ka PHP, a he mea nui ka mālama a me ka nānā ʻana e pale aku i nā hoʻoweliweli palekana. Inā pili ʻoe i ka palekana, ʻO Python ka koho maikaʻi loa. Nui nā hiʻohiʻona palekana a hiki ke mālama i nā noi paʻakikī.

He paʻakikī ke aʻo ʻana i kahi ʻōlelo papahana hou, akā ʻoi aku ka maʻalahi ma mua o kou manaʻo. Inā he mea hou ʻoe i ka coding, he manaʻo maikaʻi e hoʻomaka me ka ʻōlelo maʻalahi hiki iā ʻoe ke aʻo, a laila hoʻonui mai laila. He manaʻo maikaʻi nō hoʻi e hoʻomaka me kahi ʻōlelo e hana pū ana me nā hale waihona puke a me nā papa hana. Eia hou, he mea nui e noʻonoʻo i ke ʻano o ka papahana āu e makemake ai e hoʻokō me ka ʻōlelo.

Inā he mea hou ʻoe i ka manaʻo o ka hoʻomohala pūnaewele, He koho paha ʻo PHP iā ʻoe. He mea maʻalahi ke hoʻomaka me PHP. He nui nā noi o ka ʻōlelo a hiki ke kōkua i kekahi mea polokalamu. Akaka a hiki ke heluhelu ʻia kāna syntax, he mea kūpono ia no nā poʻe hoʻomaka. He koho kaulana ia no nā mea hoʻomohala pūnaewele.

ʻOi aku ka wikiwiki o PHP ma mua o nā ʻōlelo papahana ʻē aʻe. Ua hoʻomaikaʻi ʻo PHP 7.x i ka hōʻuluʻulu code a ʻoi aku ka wikiwiki o 2x ma mua o kona mua. Me kāna mau hiʻohiʻona hou e like me Zend Engine 3.0, ʻOi aku ka wikiwiki o ka PHP. Eia kekahi, ʻoi aku ka maʻalahi o ka ʻōlelo ʻana i nā koi ma mua o nā ʻōlelo papahana ʻē aʻe.

I ka wā e pili ana i ka papahana, He koho kaulana ʻo PHP no nā mea hoʻomohala pūnaewele. He maʻalahi ke aʻo a hoʻohana, a ʻoi aku ka maʻalahi ma mua o Java. Hāʻawi ia iā ʻoe e hana me ka code arbitrary a manuahi, he pōmaikaʻi nui ia no nā mea hoʻomohala. Eia kekahi, He kumu wehe ʻo PHP a holo ma luna o kekahi paepae.

Papahana Hoʻopono-mea (OOP) He ala ia i ka hoʻolālā ʻana e hoʻohana ana i nā mea ma ke ʻano he hale kūkulu o kahi papahana. Ma keia hana, ua wehewehe ʻia nā mea he mau mea e noho nei i kēia manawa. Hiki i kēia mau mea ke loaʻa nā waiwai a pili pū me nā mea ʻē aʻe. 'Oko'a nā mea mai nā papa, ʻo ia nā ʻāpana paʻa o ke code pono e loiloi ʻia a noho like. Hoʻohana ʻo PHP i kahi hierarchy o nā papa, kapa ʻia Nā mea, e hoʻonohonoho i ka hana o kahi papahana.

He mea maʻalahi ka hoʻohana hou ʻana a me ka mālama ʻana i nā code. Hoʻohana pinepine ʻia nā manaʻo o Object-Orientation i nā noi paʻakikī. PHP 5 loaʻa nā mea maikaʻi ma mua o nā mana mua. No hoʻokahi, Hāʻawi ia i ka mana ʻoi aku ka maikaʻi ma luna o nā ʻano a me nā waiwai. ʻAe kēia i nā mea hoʻomohala e kākau i nā noi paʻakikī i ka manawa liʻiliʻi.

Hāʻawi pū ʻo PHP i nā ʻano hana kilokilo, ʻaʻole i kāhea pinepine ʻia e ka mea hoʻohana akā kāhea ʻia e PHP ke hoʻokō ʻia kekahi mau kūlana. Ua kapa ʻia kēia mau ʻano me ka lua-understroke, ʻoiai ʻoi aku ka maikaʻi o ka pale ʻana i ka hoʻohana ʻana i kēia ʻano i ka wā e hoʻopaʻa inoa ai. Hiki ke hui pū ʻia nā ʻano hana i nā hui.

Ma PHP, nā papa he waiwai pilikino a lehulehu. ʻO nā waiwai pilikino ka mea palekana loa. Loaʻa nā waiwai pilikino e nā lālā o ka papa. Nā waiwai pilikino, e like me ka mea i hana ʻia i kekahi mea, ʻaʻole hiki ke ʻike ʻia e ka lehulehu. Hiki i nā papa ke hoʻohana i ka pfeiloperator -> e komo i kā lākou mau waiwai a me nā ʻano hana.

Hāʻawi ka papahana Object-Oriented i nā mea hoʻomohala e hoʻohālike i ka honua ma ke ʻano o nā mea. Loaʻa i kēia mau mea nā ʻikepili a me nā ʻano hana a hiki ke hoʻohana ʻia i nā ʻano hana like ʻole. Ua wehewehe ʻia nā papa e hui pū i nā mea like. Ke wehewehe ʻia kahi papa, hiki i ka Object ke hana i nā hana he nui a hoʻohana hou ʻia.

Hāʻawi ka papahana Object-Oriented i nā mea hoʻomohala e kākau i nā papahana e hoʻohana ana i kahi waihona. Hiki ke hana a mālama ʻia nā mea i loko o nā faila PHP. Hiki kēia ma ka hoʻohana ʻana i nā arrays. Me ka hoʻohana ʻana i nā arrays, hiki iā ʻoe ke mālama i nā waiwai he nui i ka manawa hoʻokahi. Hiki iā ʻoe ke hoʻohana i kahi kauoha i kūkulu ʻia i kapa ʻia echo. Hiki iā ʻoe ke hoʻokomo i nā snippet code i loko o ka HTML i loaʻa.

E like me ka inoa, Hoʻohana ʻia ka papahana Object-Oriented i nā kūlana e hoʻomalu i ke kahe o ka ʻike. He ʻokoʻa koʻikoʻi kēia ma waena o ka imperative a me ka hoʻolālā hana. ʻOiai hoʻohana nā ʻōlelo ʻelua i nā kūlana no ka mālama ʻana i ka ʻikepili, ʻO kahi ʻano hana pono e ʻoi aku ka abstraction a me ka maʻalahi. Hiki i nā mea hoʻomohala PHP ke kākau i nā code e hana maikaʻi ana no kā lākou hui me ka hoʻohana ʻana i kahi ʻano ākea.

Hoʻohana pū ʻo OOP i ka manaʻo o kahi papa, ʻo ia ka mea e hōʻike ana i kahi mea maoli. ʻO kahi mea he laʻana o ka papa. ʻo kahi laʻana, inoa o ke kanaka, makahiki, helu kelepona, a hiki ke mālama ʻia nā ʻike ʻē aʻe i loko o ka papa o ke kanaka. Hiki i kekahi mea ke loaʻa nā ʻano a me nā waiwai e hiki ai iā ʻoe ke hana i nā hana ma luna.
