thanks gan udah bisa :D @sykmaw

sippp sama sama gan

kok saya punya gagal terus yah

<?php

$host = 'localhost'; $user = 'root'; $password = ''; $db = 'cobaja';

$link = mysql_connect($host, $user, $password, $db) or die(mysql_error());

?>

ini koodingan saya. pesan yang muncul

Fatal error: Uncaught Error: Call to undefined function mysql_connect() in C:\xampp\htdocs\konek.php:9 Stack trace: #0 {main} thrown in C:\xampp\htdocs\konek.php on line 9

apakah ada coodingan atau langkah2 yang harus dilakukan terlebih dahulu sebelum mengkoneksinkan database? terima kasih

ada yang punya masalah kaya ginikah mirip? udah ikutin tutorialnya cuma ga tau apa yang problem uda cari google jg. Daripada buat forum baru tapi erornya mirip apa bisa sekalian tanya ya.

Warning: mysqli_connect() expects parameter 5 to be int, string given in C:\xampp\htdocs\test_file\auth_php\functions\db.php on line 9

Warning: mysqli_error() expects exactly 1 parameter, 0 given in C:\xampp\htdocs\test_file\auth_php\functions\db.php on line 9

kodenya seperti ini

<pre> &lt;?php

$host = 'localhost'; $user = 'root'; $password = 'root'; $HP ='root'; $db = 'teaja';

$link = mysqli_connect($host, $user, $password, $HP, $db) or die(mysqli_error()); ?&gt; </pre>

Bukannya parameter mysqli_connect hanya butuh 4 gan ?

<pre> mysqli_connect('localhost','user','password','database'); </pre>

Coba hapus variabel $hp gan, semoga membantu

kosong kan aja isi variable $password, seperti: <pre> &lt;?php

$host = 'localhost'; $user = 'root'; $password = ''; $db = 'teaja';

$link = mysqli_connect($host, $user, $password, $db) or die(mysqli_error()); ?&gt; </pre>
