我收到以下错误。有人在我的代码中看到了这个问题吗？感谢。

警告：PDOStatement :: execute（）[pdostatement.execute]：SQLSTATE [HY093]：参数号无效：参数未在（我的文件）第309行（执行行）中定义

注意：名称中带“array”的变量不是实际数组。

这是MySQL的奇怪特性，但您不能在MATCH() AGAINST()的参数中使用查询参数占位符。

您必须在prepare()之前插入字符串，因此它是SQL查询中的字符串文字。请务必使用PDO::quote()以确保正确转义特殊字符。

示例：

$keyword_quoted = $DBH->quote($keyword);

$STH = $DBH->prepare("select jp.jobpost_id,jp.zipcode 
  FROM jobposts jp 
  JOIN zipcodes zc ON jp.zipcode=zc.zipcode 
  JOIN employers em ON jp.employerid=em.employerid 
  WHERE MATCH (jp.description) AGAINST ($keyword_quoted IN BOOLEAN MODE) AND
  . . .

当然，您可以跳过bindValue($keyword)。
