In PHP, directly using mysqli::query() to execute SQL query strings separated by multiple semicolons will usually only process the first query. This article will introduce in detail two methods to effectively execute multiple MySQL queries in PHP: one is to use SQL's UNION operator to merge multiple SELECT statements into a single result set, which is suitable for queries with the same result structure; the other is to use the mysqli::multi_query() function, which can handle any number and type of SQL statements, but requires more complex code to traverse the result set of each query. The article will also emphasize security and performance considerations in multi-query scenarios.
