PHP: te huānga whakamutunga. He ngohi o akiaki

PHP - he whaihua, me te hou: he wetereo kounga me semantics o te kaha ki te mahi i tua atu te mea e tukua. Whakatinanatanga o nga whakaaro o te hōtaka ahanoa-hāngai me te haere noa o te huri i te momo o te tāupe e te parau mau o te ahua tino maia.

Huānga - hoahoa tawhito, me te herekore - he wa takoha, nui atu i te titauraa o te mahi. Ahakoa i reira e he maha rawaka o ngā mahi e whai wāhi te hanga o te raraunga kore ka whakatauria ngā mua ihirangi (rahinga, uara, momo me waehere), e he wātea ana mō te mātakitaki me te whakamahi i roto i huringa PHP forEach. E wātea ana hoki tetahi tikanga o te hanga i te huānga whakamutunga o te ngohi. Ngohi - te herekore mua, me te - tukua ki a koutou te hanga rārangi, engari i roto i te wetereo mua, ko PHP o iti whakamahi.

uara o nāianei o te ngohi

Ki te tau'a ore koe i te taupū me te whakamahi hoahoa

$ ArData [] = scField hou (); // scNumber, scString, scParagraph, ...

i reira scField () - Constructor ahanoa waitara - "mongamonga o ngā mōhiohio", e kua kainga: ki te tau (scNumber), string (scString), ngā kīanga (scParagraph), ... te tiki i te PHP: te huānga whakamutunga = ngohi o ngā whakaahua ona āhuatanga rite te te huānga tūturu.

Hono mo'oní, pe ko e hā huānga whakaaro e hāngai ana, engari i roto i tenei take, ko te mea e tika ana ki te whai i te atatohu (i roto i te PHP - pehu) i roto i te ngohi. More maha - Me ki te whai ratou ake atatohu pūtau. Akiaki i roto i te PHP pehu hapa te whakaaro o "te huānga whakamutunga = ngohi". Wātea i roto i te mutunga mahi () me array_pop (), te huānga whakamutunga rite te māngai ki te ngohi āhuatanga. Mā te array_pop (), i roto i te tua, huri aunoa ki te huānga ngohi o mua, me te e whakarerekētia ona āhuatanga fakatatau. meinga tenei e te taea o te kaupapa o te huānga.

Ko te kupu, whakaaro i roto i te horopaki o PHP wetereo, te tango i te huānga whakamutunga i roto i te ngohi mau te tikanga ki te whakamahi i ona āhuatanga. Raupapa whakatakoto me te tango i ngā huānga, whiwhi tatou āhuatanga hihiri, te hihiri hou hanganga raraunga, i hanga i roto i te wetereo e wātea ana.

Origin me ētahi atu huānga

E he mahi ki te mahi ki te huānga tuatahi o te ngohi, me te neke i te atatohu ā-. I roto i te wetereo noa e whakatinana te mahi matarohia o te hōtaka, he hāngai ana ratou. Ki te whakaaro ki te hanga huānga ki hihiri te huri tikanga - e kore.

I roto i te hōtaka, ko reira tonu he pātai o-whakatau kaupapa: taurangi Ko nga tikanga te operator ki te huri i te akoranga o te hātepe, koropiko tahi mea tātari, hua iku hua.

Ki te neke koe i te pokapū o te mahara ki te tūemi tūturu me hoatu ki a ia ana whakatau ake, e te hōtaka i runga i te, titiro whai kiko katoa rerekē. Nuinga o ngā wā ko reira taea tenei tikanga ki te whakatutuki i te whāinga, tautautefito ki he taimi tae mai te reira ki, hei tauira, te whakamahi o ngā tūtohu tuhinga maha * .docx, tuhia i roto i te XML paerewa Open.

I roto i te PHP ki te tiki i te huānga whakamutunga i roto i te ngohi - reira he tikanga hou, me te whai wāhitanga pai.

Tikiake ana ngā kōnae me ngā āhuatanga hihiri o huānga

A, no te tuku i te pae te kaha ki te tiki i tetahi o nga kōnae, he reira watea ki te whakamahi i te whakaaro o te ahanoa waitara, mo te tauira, SCFile me uri i ia scImage, scDocument, scTabe, e ka whai nga āhuatanga ingoa taua, engari rerekē ratou ahua, me te tikanga (ihirangi). I roto i te horopaki o te wetereo PHP (te whakamutunga huānga = ngohi), mā te whakamahi i mutunga () mahi, ka taea e koe te whakamahi i te reira i te ara whakatau reira te huānga whakamutunga. Kei te ngā tenei whakatau i roto i taua whakamuri reira te whakaaturanga mua, me te taea ki a koe te whakatere i te hanganga raraunga rite hoki kua hanga i te reira.

Taua whakamahi o ngā huānga homai ratou he tikanga rawa hou. E whakarato ana i PHP wetereo, engari taua whakamahi tuku whai wāhitanga nui.

Whakarato atahanga, rokiroki i roto i te pātengi raraunga, te ora i roto i te huru whakahaere (hei tauira), ka waiho e taea e kore ki te whakaaro e pā ana ki te mea ki te mahi i roto i te take ngā. kōnae katoa tukuake e whakanohoia i roto i te raupapa ngohi, a ka te tukatuka reira, kua karangatia e tonu te taua tikanga mo te kaupapa kotahi, engari ka whakaaturia te kōnae image rite ko, te kōnae ripanga - rite te tepu, me te tuhinga - te kuputuhi hāngai. Wātea i roto i te wetereo PHP o te huānga whakamutunga o te ngohi e taputapu ona ake āhuatanga, me te ihirangi motuhake.

I roto i te take whakamutunga, ko te tuhinga tonu pūāhua, aho, tau, me, tino nui, whakahōputu. Kia mau ki he uaua te ara o ia pūmotu, engari na te whakarato i te ahanoa tika mō ia huānga hōputu taea te whiwhi, te feaa-ore, te tuhinga rite ko reira.

Stack ko Recursion roto wetereo

A, no te e mahi tatou i anake ki te huānga whakamutunga, te huru matua - he tāpae, engari ka mahi i tenei tūemi te, a whakamahia e te reira i te taua hanga, a rawa ia - he recursion. Ka taea e tatou te mea maha nga mea pai e pā ana ki ngā whare pukapuka PHPOffice, taua PHPWord, engari tohe e ite ratou tikanga tonu-parirau e whakawhiti te hōpututanga taketake o te tuhinga i roto i te hua, e kore e taea e koutou.

Oia mau, e taea te whakamahi i PHPOffice \ PHPWord ka kia ngāwari whakatuwhera tetahi Tuhinga vordovsky (* .docx), engari te mea pūranga maha hanganga xml-kōnae, pikitia, me ētahi atu taonga anake.

I te wa ano, ki te tango tatou anake te xml-kōnae, ahakoa e pā ana ratou (i roto i ngā o momo, tepu, pikitia), e kore e mahi ki te hanga i tētahi tuhinga hou e hāngai ana i runga i tawhito, me te tika oho ki tona huringa hiahiatia (hei tauira, te huri i te tae momotuhi, hōputu). Kōwhiringa ki te tono ngā tūtohu Open huinga XML, a tae noa te hua pera-whakapumautia rite MS Word, e kore fekuki tonu ki ngā whakaaro a te kaiwhakamahi, kia hape.

kōnae Mau * .docx - he zip-pūranga, me te hanganga mārama, me te mārama. Mā te taea te whakaahuatia ōkawa he maha iti o ngā reira, ka whiwhi i te wa o te tai'oraa i te tonu, hanganga raraunga motuhake, e taea te whakahaere semantically.

I roto i tenei take, te mōhiohio i roto i te tuhinga - te hanganga raraunga ōkawa. Me te reira i te au, ka taea e ngāwari koe heke ki te taumata o te tikanga, me te tau'a ore i te wetereo.
