mysqli_real_query
(PHP 5, PHP 7, PHP 8)
mysqli::real_query -- mysqli_real_query — 执行一个mysql查询
说明
面向对象风格
过程化风格
对数据库执行单条查询，其结果可以使用 mysqli_store_result() 或 mysqli_use_result() 检索或存储。
警告
Security warning: SQL injection
If the query contains any variable input then parameterized prepared statements should be used instead. Alternatively, the data must be properly formatted and all strings must be escaped using the mysqli_real_escape_string() function.
为了确定给定的查询是否应返回结果集，参阅 mysqli_field_count()。
错误／异常
If mysqli error reporting is enabled (MYSQLI_REPORT_ERROR) and the requested operation fails,
a warning is generated. If, in addition, the mode is set to MYSQLI_REPORT_STRICT,
a mysqli_sql_exception is thrown instead.
