php mysqli_query结果没有

参见英文答案 > How do I get PHP errors to display? 24个
我试图使用MysqLi_query从表中获取数据.
当我使用以下命令时,它可以正常工作：

$hostname = "********";
$username = "*******";
$password = "********";
$databaseName = "**************";
$dbConnected = MysqLi_connect($hostname,$username,$password,$databaseName);

当我尝试包含上述代码的文件包括(‘../ htconfig / dbConfig.PHP’);然后我没有得到任何结果：

……“0结果”

PHP

include('../htconfig/dbConfig.PHP');
$dbConnected = MysqLi_connect($db['hostname'],$db['username'],$db['password'],$db['databaseName']); 

if(!$dbConnected) {
    die('Connect Error (' . MysqLi_connect_errno() . ') '
            . MysqLi_connect_error());
}
echo 'Success... ' . MysqLi_get_host_info($dbConnected) . "\n". "MysqLi_set_charset($dbConnected,"utf8");

$tPerson_sqlselect = "SELECT  ";
$tPerson_sqlselect .= "ID,Salutation,FirstName,LastName,CompanyID ";    
$tPerson_sqlselect .= "FROM ";
$tPerson_sqlselect .= "tPerson ";           

$result = MysqLi_query($dbConnected,$tPerson_sqlselect);

if (MysqLi_num_rows($result) > 0) {
// output data of each row
while($row = MysqLi_fetch_assoc($result)) {
    echo "Salutation: ".$row["Salutation"]. "-FirstName: ".$row["FirstName"]." ".$row["LastName"]."  -CompanyID: ".$row["CompanyID"]. "MysqLi_close($dbConnected);
?>

我找不到我的错误..
请帮忙！

dbConfig.PHP 文件：

PHP
$db = array(
'hostname' => '*****','username' => '*****','password' => '*****','database' => '*****',); 
?>

最佳答案

如果您仍在使用相同的变量名,那么$dbConnected应该是这样的：

include('../htconfig/dbConfig.PHP');
$dbConnected = MysqLi_connect($hostname,$databaseName);

如果你想要它是$db [‘field’]那么你的../htconfig/dbConfig.PHP应该是这样的：

$db = array('hostname' => 'xxxx','username' => 'xxxx','password' => 'xxxx','databaseName' => 'xxxx');

编辑：
你在dbConfig.PHP中的数组说’数据库’,但你在$dbConnected MysqLi_connect函数中使用了’databaseName’？
