Question

我的数据数据存在问题。我的阵列是：

$dataarray=array("FECHAS" => date("Y-m-d"),"HORAS" => date("H:i:s"),"RGD" => 0,"RGA" => 0,"FLU" => 0,"DD2" => 0,
             "H2O" => 0,"PRES_U" => 0,"U" => 0,"V" => 0,"TS" => 0,"T1" => 0,"T2" => 0,"H1" => 0,"H2" => 0, "HS" => 0,
             "VV1" => 0,"VV2" => 0);

我尝试将我创建的数据中的数据复制到我的数据库中，但现在奇怪的值开始变得越来越好，我不知道它们来自何处以及如何删除它们：这是我用来放置数据的代码一个数组进入DB：

//___________________ PUT DATA INTO SQL_______________________________

for($j=0;$j<$variable_para_base;$j++)
{
$keys = array();
$vars = array();
foreach($dataarray[$j] as $k=>$v)
{
    $keys[] = $k;
    $vars[] = $v;
}

$columns = implode(", ",$keys);
$escaped_values = array_map('mysql_real_escape_string', $vars);
$values = implode("', '", $escaped_values);

//$query = "INSERT INTO var ($columns) VALUES ('$values')";

$query = "INSERT INTO var (FECHAS,HORAS,RGD,RGA,FLU,DD2,H2O,PRES_U,U,V,TS,T1,T2,H1,H2,HS,VV1,VV2) VALUES ('$values')";


echo "<br>"." / ".$vars[16]." / ".$vars[17]." / ".$vars[18]."<br>"
        ." / ".$keys[16]." / ".$keys[17]." / ". $keys[18]."<br>";
echo $query;
echo "<br>Numero de variables: ".count($keys)."<br>";
//implode the arrays and separate by comma

$statement = $mysqli->prepare($query);
$result = $statement->execute(); //execute.

if($result) {
    print "Array inserted, worked like a charm.";
}
else {
    print "I failed, sorry...". $mysqli->error();
}

unset($keys);
unset($vars);

} $陈述式＆GT;关闭（）;

我的初始数组中的数据看起来像这样，为了从一行移动到另一行，我使用$ j：

2014-02-23 19:46:33 -5.36 0 0.34 0 0,0 0.66 -1.93 0 0,7.79 75.02 40.18 -0.07 0,0
2014-02-23 20:16:40 -4.58 1.44 0 0 -0.0,0 0 2.04 0 3.47,0 90.99 0 0 0,-2.06
2014-02-23 20:53:14 -4.05 0 0 -4.70 -0.0,0 1.21 0 8.05 3.10,0 96.69 55.74 -0.07 0,0
2014-02-23 21:27:37 0 -5.10 0 137.12 0,0 -5.60 1.59 8.17 10.53,0 42.53 35.88 0 0,0

但是，当我看到数据时，我将数据放入数据库奇怪的值。

/ 0 / 0 /
/ VV1 / VV2 /
INSERT INTO var (FECHAS,HORAS,RGD,RGA,FLU,DD2,H2O,PRES_U,U,V,TS,T1,T2,H1,H2,HS,VV1,VV2) VALUES ('2014-02-23', '19:46:33',   '-5.36', '0', '0.34', '0', '0', '0', '0.66', '-1.93', '0', '0', '7.79', '75.02', '40.18', '-0.07', '0', '0')

Numero de variables: 19

因为这个我无法将数据上传到数据库中而且不知道我的错误在哪里我也创建了一个包含来自我的数组的数据的文件，但是我使用了像$ dataarray [“FECHAS”]这样的值而不是foreach功能。有什么想法吗？

EDITED

echo "<br>Var_Export J =0 ...: ";
var_export($dataarray[$j]);
echo "<br>Var_Export J =5";
var_export($dataarray[5]);
echo "<br>Var_Export J = $variable_para_base";
var_export($dataarray[$variable_para_base-1]);
echo "<br> Var_Export ...: ";
var_export($dataarray);
foreach($dataarray as $ind=>$arr)
{
var_export($dataarray);
foreach($arr as $k=>$v)
 {
    $keys[] = $k;
    $vars[] = $v;
 }

    $columns = implode(", ",$keys);
    $escaped_values = array_map('mysql_real_escape_string', $vars);
    $values = implode("', '", $escaped_values);

$query = "INSERT INTO var ($columns) VALUES ('$values')";

//$query = "INSERT INTO var (FECHAS,HORAS,RGD,RGA,FLU,DD2,H2O,PRES_U,U,V,TS,T1,T2,H1,H2,HS,VV1,VV2) VALUES ('$values')";

echo $query;
$statement = $mysqli->prepare($query);
$result = $statement->execute(); //execute.

if($result) {   print "<br>Array inserted, worked like a charm.";   }
else {      print "I failed, sorry...". $mysqli->error();   }

unset($keys);
unset($vars);
}
$statement->close();


//________________________ END PUT IN________________________________________

现在我把var_export（）的结果：我事先评论它给了少量j的结果但是当我试图访问整个块时它给了我一个警告。

最后编辑：这是我执行print_r时获得的（$ dataarray）;它继续，它不是整个执行，当它变得太大时我不得不停止它。

Answer 1

您不需要第一个for循环。

    foreach($dataarray as $ind=>$arr){
    {
     foreach($arr as $k=>$v)
     {
        $keys[] = $k;
        $vars[] = $v;
     }

    $columns = implode(", ",$keys);
    $escaped_values = array_map('mysql_real_escape_string', $vars);
    $values = implode("', '", $escaped_values);

    //...the rest of your insert code


    unset($keys);
    unset($vars);
    }
    $statement->close();

由于您说$dataarray已嵌套数组，因此您可以使用上述两个foreach。

Array拥有的数据超出了应有的数据
