将foreach作为数组提交给MySQL

Question

I am needing away to insert data to a database based on an auto generated list from a form.

So I have this that lists out the key and value, but I need to create an array that I can then use a $sql insert to database.

foreach ($_POST as $key => $value) {
        if($value != "") {
            print $key.": ".$value . "<br>";
        }
}

So then I have this for $sql insert

$sql = "INSERT INTO FDPU ($key) VALUES ('$value')";
if ($conn->query($sql) === TRUE) {
echo $key.'='.$value.'New record created successfully'.'<br />';
} else {
echo "Error: " . $sql . "<br>" . $conn->error;
}

Not tested, but something like this should do it:

$keys = array();
$values = array();

foreach ($_POST as $key => $value) {
        if($value != "") {
            $keys[] = $key;
            $values[] = "'" . $value . "'";
        }
}

$sql = "INSERT INTO FDPU (" . implode(',', $keys) . ") VALUES (" . implode(',', $values) . ")";

It stores the keys and values of the variables that are not empty, and then put them together using the very handy function implode.
