mysql_info
Get information about the most recent query
This extension was deprecated in PHP 5.5.0, and it was removed in PHP 7.0.0. Instead, the MySQLi or PDO_MySQL extension should be used. See also MySQL: choosing an API guide and related FAQ for more information. Alternatives to this function include:
mysqli_info

string mysql_info(resource link_identifier= =NULL);
Returns detailed information about the last query.
link_identifier
The MySQL connection. If the link identifier is not
specified, the last link opened by
mysql_connect
is assumed. If no such link is found, it will try to
create one as if
mysql_connect
had been called with no arguments. If no connection is
found or established, an E_WARNING
level error is generated.
Returns information about the statement on success, or
false
on failure. See the example below for
which statements provide information, and what the returned
value may look like. Statements that are not listed will return
false
.
Example 6.37 Relevant MySQL Statements
Statements that return string values. The numbers are only for illustrating purpose; their values will correspond to the query.
INSERT INTO ... SELECT ... String format: Records: 23 Duplicates: 0 Warnings: 0 INSERT INTO ... VALUES (...),(...),(...)... String format: Records: 37 Duplicates: 0 Warnings: 0 LOAD DATA INFILE ... String format: Records: 42 Deleted: 0 Skipped: 0 Warnings: 0 ALTER TABLE String format: Records: 60 Duplicates: 0 Warnings: 0 UPDATE String format: Rows matched: 65 Changed: 65 Warnings: 0
mysql_info
returns a non-false
value for the INSERT
... VALUES statement only if multiple value lists are
specified in the statement.
