數(shù)據(jù)庫連接失敗....
$link = mysql_connect('127.0.0.1', 'root', 'root','3307') or die('數(shù)據(jù)庫連接失敗');
mysql_select_db('phpdata');//選擇一個需要操作的數(shù)據(jù)庫
mysql_query("set names 'utf8'");
if (!$link) {
die('Could not connect: ' . mysqli_error());
}
echo '數(shù)據(jù)庫連接成功！';
mysqli_close(!$link);
ps:本地的mysql 庫端口已經(jīng)改成3307了.

先測試一下配置有沒有問題，再試試前端數(shù)據(jù)能不能傳入數(shù)據(jù)庫
