【问题描述】：

//这里是完整的脚本。我需要将返回的数组结果发送到 mysql。我在 mySQL 插入函数上尝试了许多变体，但 mysql 仍然不会填充数据。 mysql中的表有列名'date'，'home'，'score'，'away'。我使用 xamp 作为本地主机，数据库名称：'brazil'，表名：'seriea'。任何想法，将不胜感激！谢谢。

<?php 

$data = array();
$html = file_get_contents('http://www.soccerstats.com/round_details.asp?league=brazil'); //get the html returned from the following url
$doc = new DOMDocument();
libxml_use_internal_errors(true);

if(!empty($html)){
    $doc->loadHTML('<meta http-equiv="content-type" content="text/html; charset=utf-8">'.$html);
    libxml_clear_errors();
    $xpath = new DOMXPath($doc);

    $entries = $xpath->query('//table[@class="stat"]');
    foreach($entries as $key => $value) {



        $data[] = array(
            'date' => trim($value->getElementsByTagName('font')->item(0)->nodeValue),
            'home' => trim($value->getElementsByTagName('font')->item(1)->nodeValue),
            'score' => trim($value->getElementsByTagName('font')->item(2)->nodeValue),
            'away' => trim($value->getElementsByTagName('font')->item(3)->nodeValue),
        );
    }
}


echo "<pre>";

print_r($data);
echo "</pre>";

// Create connection
$con=mysqli_connect("***","***","***");
mysqli_select_db('brazil', $con);

// Check connection
if (mysqli_connect_errno()) {
  echo "Failed to connect to MySQL: " . mysqli_connect_error();
}

else
{
$date = $_POST['date'];
$home = $_POST['home'];
$score = $_POST['score'];
$away = $_POST['away'];
$sql="INSERT INTO seriea (date, home, score, away) VALUES ('$date','$home','$score','$away')";
if (!mysqli_query($sql,$con))
{
die('Error: ' . mysqli_error());
}
else{
echo "1 record added";
}
}
mysqli_close($con);
?>

//输出到mysql//

【问题讨论】：

它仍然无法工作 - 准确、简洁且完全没用。解释什么不起作用，以及正在发生什么。哦 - 而且不要混用对 mysql_*() 和 mysqli_*() 的调用。只需使用mysqli_*()。
你好，你为什么使用$_POST？数据在$data

标签： php mysql phpmyadmin sql-insert

【解决方案1】：

从数据所在的$data 开始，您需要从中构建查询。考虑这个例子：

$values = '';
$initial_statement = 'INSERT INTO `seriea` (`date`, `home`, `score`, `away`) VALUES ';
foreach($data as $key => $value) {
    $values[] = "('".implode("','", $value)."')";
}

$values = implode(',', $values);
$complete_statement = $initial_statement . $values;
$query = mysqli_query($con ,$complete_statement);

$complete_statement 应该会产生这样的结果：

INSERT INTO `seriea` (`date`, `home`, `score`, `away`) VALUES ('1 Jun 14',' Fluminense ','1 - 1',' Internacional '),('1 Jun 14',' Vitória ','0 - 1',' Sport Recife '),('1 Jun 14',' Corinthians ','1 - 1',' Botafogo '),('1 Jun 14',' Chapecoense ','2 - 1',' Bahia '),('1 Jun 14',' Cruzeiro ','3 - 0',' Flamengo '),('1 Jun 14',' Santos ','2 - 0',' Criciúma '),('1 Jun 14',' Grêmio ','0 - 0',' Palmeiras '),('1 Jun 14',' Figueirense ','1 - 3',' Atlético PR '),('31 May 14',' São Paulo ','2 - 1',' Atlético MG '),('31 May 14',' Coritiba ','3 - 0',' Goiás '),('30 May 14',' Bahia ','0 - 2',' Santos '),('29 May 14',' Internacional ','2 - 0',' Chapecoense '),('29 May 14',' Flamengo ','1 - 1',' Figueirense '),('29 May 14',' Atlético MG ','2 - 0',' Fluminense '),('29 May 14',' Atlético PR ','2 - 2',' São Paulo '),('29 May 14',' Corinthians ','1 - 0',' Cruzeiro '),('29 May 14',' Goiás ','0 - 0',' Vitória ')

Important Note: Please add this on top of your php file

header('Content-Type: text/html; charset=utf-8');

这样你就会得到 "Fluminense" 而不是 "Â Fluminense"
