How does mysql_fetch_array block data-free errors? when I connect to a database using PHP, I use mysql_fetch_array to retrieve database data. If the table in the database has no content, an error message containing at least one element is displayed. If there is no data, no data is output, and no php error prompt is displayed, what should I do? How does mysql_fetch_array block error messages without data?

Error_reporting (0 );
$ Query = mysql_query ($ SQL );
Mysql_fetch_array ($ query );

Error_reporting (0 );
Does this statement block all errors?
Yes. If you want to block a single error, write it like this.
@ Mysql_fetch_array ($ query );
