php - 数组值存入mysql

Question

我有一个看起来像这样的数组:

Array ( [0]  => 'overview' 
        [53] => 'PUBLIC' 
        [54] => '-friendsD' 
        [55] => 'XHTML' 
        [56] => '1.0' 
        [57] => 'Transitional' 
        [77] => 'People' );

如何获取这些值并使用 INSERT 将它们放入 MySQL？例如INSERT INTO array_value VALUES ('$arrayvalues')。对于每个数组值都是 MySQL 中的一个新帖子。

我尝试过这个:

  <?php
$homepage = file_get_contents('http://www.mysiteexample.com/');
$array = explode(" ",$homepage);
foreach($array as $val) {
$servername = "localhost";
$username = "111";
$password = "111";
$dbname = "111";
    // Create connection
$conn = new mysqli($servername, $username, $password, $dbname);
    // Check connection
if ($conn->connect_error) {
    die("Connection failed: " . $conn->connect_error);
} else {
if ($val != " "){
$val = $val. " ";
    $query = "INSERT INTO `111` (word) VALUES ('$val')";

       $executeQuery = $conn->query($query) === TRUE;

    }

    if ($executeQuery === TRUE) {
        //echo "New record created successfully";
echo $val;
    } else {
        //echo "Error: " . $query . "<br>" . $conn->error;
echo $val. " ";
    }}
    $conn->close();
}
?>

这在一定程度上是有效的。它会产生许多空结果，如何将其过滤为没有空帖子。我尝试了 $val != ""但这不起作用。

您可以循环遍历数组并构建查询。然后执行它。

<?php
$homepage = file_get_contents('http://www.mywebsite.com/');
$array = explode(" ",$homepage);

$servername = "localhost";
$username = "username";
$password = "password";
$dbname = "myDB";

    // Create connection
$conn = new mysqli($servername, $username, $password, $dbname);
    // Check connection
if ($conn->connect_error) {
    die("Connection failed: " . $conn->connect_error);
} else {
    $executeQuery;

    for ($i = 0; $i < count($array); $i++) {
        if (!empty($array[$i])) {
            $executeQuery = $conn->query("INSERT INTO `yourTable` (yourField) VALUES ('" . $array[$i]  . "')");
        }
    }

    if ($executeQuery === TRUE) {
        echo "New record created successfully";
    } else {
        echo "Error: " . $query . "<br>" . $conn->error;
    }
    $conn->close();
}
?>
