语法错误，意外＆＃39; $ query＆＃39; （T_VARIABLE）

Question

$koneksi = mysqli_connect($host_name, $username, $password, $database);

$query = mysqli_query($koneksi, "SELECT * FROM pembeli");
$hasil = mysqli_query($query);

while ( $buyer = mysqli_fetch_assoc($hasil)){
    echo $buyer ['Nama'];
    echo $buyer ['Barang'];
    echo $buyer ['Retribusi'];
}

我有那行代码，它的生成语法错误意外＆＃39; $ query＆＃39;（T_VARIABLE）。怎么了 ？

Answer 1

在mysqli中无需写： - mysql_select_db($database);

因为第四个参数是数据库名称

示例： - mysqli_connect($localhost, $username, $password, $database);

更新您的代码，如下所示

$database  = "jaka_crud_ci";

$koneksi = mysqli_connect($host_name, $username, $password, $database);

$query = mysqli_query($koneksi, "SELECT * FROM pembeli");

while ( $buyer = mysqli_fetch_assoc($query)){
    echo $buyer['Nama'];
    echo $buyer['Barang'];
    echo $buyer['Retribusi'];
}
