我在爆炸行中遇到解析错误。
我只想使用已经存储在数据库中的关键字（布拉德·皮特，搏击俱乐部，项目混乱），然后将其转换为逗号分隔的数组。然后将该数组与新的用户输入合并。

<?php
$tags = $_POST['tagArray'];
$title = $_POST['title'];

$DBServer = "localhost";
$DBUser = "------";
$DBPass = "-------";
$DBName = "movies";

$conn = mysqli_connect($DBServer, $DBUser, $DBPass, $DBName);


$query = "SELECT keywords FROM movieTitles WHERE movie='" .$title. "'";
$result = mysqli_query($conn, $query);
$row = mysqli_fetch_array($result);
$keywords = $row['keywords'];

$current = explode("," $keywords[0]);
$array = array_unique(array_merge($tags,$current));

echo $array;

mysqli_close($conn);

?>

最佳答案

$current = explode(",", $keywords[0]);

您错过了一个逗号
