Php 从MySQL数据库生成数组

我有数据库连接。我想做一个数组，但我觉得有些问题。这是我的数组代码：

$var = "SELECT SUBSTRING(KayitTarihi,1,4) AS year,SUBSTRING(KayitTarihi,6,2) AS month,SUBSTRING(KayitTarihi,9,2) AS day,SUBSTRING(KayitTarihi,12,2) AS saat,SUBSTRING(KayitTarihi,15,2) AS dakika,Guc FROM Urun WHERE Date(KayitTarihi)=\"".$link_m."\"";

$result = $mysqli->query($var);

$data = array();
foreach ($result as $row) {$data[] = $row;}

print_r($data);

$no=1;$total_deger=count($data);
echo $total_deger;

for($i=0;$i<$total_deger);$i++){
    $xxx[i]="[Date.UTC(".$data[i]['year'].",".$data[i]['month'].",".$data[i]['day'].",".$data[i]['saat'].",".$data[i]['dakika'].",00),".$data[i]['Guc']."]";if($no < $total_deger){echo ",";}
    echo $xxx[i];
}

$var=“选择子串（KayitTarihi，1,4）作为年份，子串（KayitTarihi，6,2）作为月份，子串（KayitTarihi，9,2）作为天，子串（KayitTarihi，12,2）作为saat，子串（KayitTarihi，15,2）作为dakika，Guc从Urun开始，其中日期（KayitTarihi）为“.$link\u m.”；
$result=$mysqli->query（$var）；
$data=array（）；
foreach（$result as$row）{$data[]=$row；}
打印（数据）；
$no=1$总数=计数（数据）；
echo$total_deger；
对于（$i=0；$i），首先要检查SQL查询返回的行。然后我认为需要将
foreach
修改为
，而
如下所示。在循环之前还要检查返回的行

if ($result->num_rows > 0) {
    while($row = $result->fetch_assoc()) {
        $data[] = $row;
    }
}

根据此处给出的示例：
带有更正和建议的代码（均已注释）：-

语法错误：-
for（$i=0；$iyes，现在没问题了..谢谢。但是现在我的$no=1和我的if语句$noAlso
echo$xxx[i]；
应该是
echo$xxx[$i]；
当事情没有按预期工作时，请查看PHP错误日志，这也适用于这一行所有
i
变量都必须是
$xxx[i]=”[Date.UTC（“.$data[i]['year'.]”、“$data[i]['month'.]”、“$data[i]['day'.]”、“$data[i]['saat'.]”、“$data[i]['dakika'.]”、00）、“$data[i]['Guc'.]”如果（$no<$total_deger）{.echo”、“；}
在打开PHP标签后立即进行测试时添加到文件顶部，例如
我添加了一个
foreach（）
suggestion，这对您更有利。当我再次使用foreach时，只是看到，，，，，不是我的值。我的总数=9，但我的输出是[Date.UTC（，，，，，，，，，，，，，，]，[Date.UTC（（foreach或for循环，而不是两者）
