我想在php文件中打开一个计数以获得第一个寄存器
<?php
include_once('dbConfig.php');
session_start();
$id_persona= $_SESSION["id"];
$query = "SELECT COUNT( * ) AS alias1 FROM `desayuno_ingreso` WHERE `desayuno_ingreso`.`id` =88757532";
echo $query;
$resultset = mysqli_query($conn,$query);
if(mysqli_num_rows($resultset) > 0){
$k=0;
while ($fila = mysqli_fetch_assoc($resultset)) {
$lat[$k]= $fila['alias1'];
$k=$k+1;
}
}
echo $lat[0];
?>
我尝试过我所知道的每一种方式(以前每种方式都适合我)。但是,它现在不起作用。
我不确定我做错了什么。
EIDTED 这是dbConfig.php文件:
<?php
$dbHost = 'localhost';
$dbUser = 'root';
$dbPass = 'mypassword';
$dbName = 'app';
$conn = mysqli_connect($dbHost,$dbUser,$dbPass,$dbName);
if(!$conn){
die("Database connection failed: " . mysqli_connect_error());
}
?>
