Txhawm rau txuas cov ntawv ntxiv rau PHP tsab ntawv, siv cov haujlwm tshwj xeeb suav nrog. Tom qab sib txuas cov ntaub ntawv sab nraud, tus programmer muaj sijhawm los siv cov ntawv sau sau lossis lwm yam ntsiab lus hauv daim ntawv thov tam sim no.
Xws li ua haujlwm
Xws li muaj cov syntax hauv qab no:
suav nrog “file file”;
Lub npe yog tus kwv tij lossis txoj kev tsis muaj tseeb nrog kev txuas ntxiv ntawm daim ntawv sau cia. Yog tias tsis muaj qhov chaw tau teev tseg, PHP yuav saib xyuas cov ncauj lus ntawm php.ini, uas teev meej nrog rau _path - qhov chaw qhia ntxiv qhov chaw qiv tuaj yeem tso. Yog tias qhov kev taw qhia yog khoob lossis cov ntaub ntawv xav tau tsis pom ntawm txoj kev teev hauv nws, cov lus hais tawm yuav raug zam.
Thaum ua haujlwm tiav, koj tuaj yeem siv cov ntsiab lus uas koj xav tau hauv tsab ntawv, cob qhia cov hloov pauv, siv cov ntawv tshaj tawm tsim, thiab lwm yam. Piv txwv, muaj 2 cov ntawv 1.php thiab 2.php. Cov ntsiab lus ntawm 1.php zoo li no:
<? php
$ firstly = “kuj sib txawv thiab los ntawm thawj cov ntawv”;
$ secondly = “tus nqi txawv teb”;
?>
Txhawm rau suav cov nuj nqis saum toj no hauv 2.php, koj tuaj yeem ua txoj haujlwm nram qab no:
<? php
Xws li “1.php”;
ncha $ firstly;
$ tawm = "$ ob";
ncha $ muaj tawm; ?>
Hauv tsab ntawv no ntawm daim ntawv thib ob, qhov hais kom ua suav nrog cov ntsiab lus ntawm thawj daim ntawv, tom qab ntawd cov hloov pauv tau tshaj tawm nyob rau hauv 1.php tau siv los tso saib qhov tsim nyog ntawm qhov screen.
Xws li tuaj yeem siv tau ob qho tib si thaum pib ntawm cov ntaub ntawv thiab sab hauv cov haujlwm tshaj tawm hauv txhua ntu ntawm daim ntawv no. Nws yog qhov tsis tsim nyog los siv txoj haujlwm los txuas cov ntaub ntawv nyob rau ntawm cov chaw deb. Yog tias koj xav ua qhov kev zoo no, koj yuav tsum tau xaiv qhov option_url_fopen hauv php.ini cov ntaub ntawv ntawm koj lub chaw nyob deb lossis thaj chaw deb.
Yuav tsum muaj
Cov haujlwm xav tau zoo ib yam li suav nrog. Cov lus txib tsis txawv nyob hauv syntax thiab kev siv thev naus laus zis. Qhov txawv tsuas yog tias yog cov ntawv sau tseg uas ploj lawm, yuav tsum sau cov ntawv sau, thaum suav nrog yuav pib sau cov ntawv thiab saib cov lus ceeb toom E_WARNING, uas tuaj yeem raug siv siv @ cov cim tshwj xeeb. Piv txwv li:
<? php
xav tau “1q.php”;
echo “Tsab ntawv tsis ua haujlwm”; ?>
Hauv qhov ua piv txwv, txoj kev mus rau daim ntawv tsis muaj daim ntawv 1q.php yog teev. Yog tias cov ntaub ntawv ploj lawm, tsab ntawv yuav tsis coj los ua kev hais lus ncha, thiab tus neeg siv lub vijtsam yuav tso tawm cov ntawv lossis cov lus yuam kev (nyob ntawm php.ini nqis). Yog tias koj sau cov cai zoo sib xws siv nrog rau:
<? php
suav nrog “1q.php”;
echo “Tsab Ntawv txuas ntxiv”; ?>
Qhov hais kom ua ncha yuav raug tua thiab cov lus coj ua yuav tshwm rau ntawm cov zaub.
