问题是这一行:

$sql_query_holder="\"".$sql_query_holder."\"";

您的脚本不会输出整个查询，只会输出其中的一部分，然后会对其进行修改.难怪你看不到哪里出了问题.

Your script doesn't output the whole query, just part of it, which it then modifies. No wonder you couldn't see what was wrong.

它运行的查询实际上是:

The query it's running is actually:

SELECT * FROM fm_sources WHERE "excerpt LIKE '%Roy Hodgson%' OR title LIKE '%Roy Hodgson%' <etc etc> " ORDER BY tweet_count DESC

你不需要那些额外的引号

You don't need those extra inverted commas
