Khipha idatha kusuka kufayela lombhalo nge-PHP

Njengoba sonke sazi, enye yezinhloso eziyinhloko zobuchwepheshe kanye nekhompyutha ukunethezeka, futhi kulokhu sizosebenzela lula kithi program.

Izikhathi eziningi, indlela yokuphepha ehamba phambili ukwenza konke okusemandleni ukuqinisekisa ukuthi isivakashi awazi ngempela ukuthi wenzani, ngakho-ke sizogwema zonke izinhlobo zokuba sengozini okuvamile kuwebhu Ngale ndlela, ngiphakamisa ukuthi ungayilandeli imihlahlandlela elandelwa yiwo wonke umuntu lapho wenza ikhasi lewebhu, kepha uphakamisa imisebenzi ehlukile ngokwakho.

Enye yezingxenye ezibucayi kunanoma iyiphi iwebhu yi-database, ngoba yonke idatha edinga ukugcinwa, ezimweni eziningi kakhulu, izogcinwa kuyo. Ukuthola i-database sidinga imininingwane elandelayo:

• Iseva
• umsebenzisi
• Contraseña
• Igama ledatha

Imvamisa lolu lwazi lunamathiselwe kufayela elifanayo elenza umsebenzi wokuxhuma ku-database:

<?php

$link=mysql_connect("SERVIDOR", "USUARIO", "CONTRASEÑA");

mysql_select_db("BASE DE DATOS",$link) OR DIE ("Error: No es posible establecer la conexión");

mysql_set_charset('utf8');

?>

Kodwa-ke, njengenjwayelo, kunenye indlela yokwenza izinto, singakwazi ukugcina le datha eyimfihlo kakhulu kufayela elihlukile kunalelo elenza umsebenzi, bese ukhawulela izimvume kulelo fayela.

Kulokhu sizosebenzisa umsebenzi i-rtrim, umsebenzi we khipha idatha kufayela lombhalo elijwayelekile. I-.txt kufanele iqukathe idatha eyodwa kulayini ngamunye, okuthile okufana nalokhu:

Futhi sizokhipha idatha eshiwo kamuva, kufayela elenza ukuxhumana:

<?php
$datos='datos.txt';
$todos_los_datos=file($datos);
$servidor=rtrim($todos_los_datos[0]);
$usuario=rtrim($todos_los_datos[1]);
$clave=rtrim($todos_los_datos[2]);
$basededatos=rtrim($todos_los_datos[3]);
$conectar=mysql_connect($servidor, $usuario, $clave);
mysql_select_db($basededatos, $conectar);
?>
