(PHP 4 >= 4.3.0, PHP 5)

mysql_info — Get information about the most recent query

Warning

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. Alternatives to this function include:

mysqli_info()

Description

function mysql_info(resource $link_identifier = NULL): string

Returns detailed information about the last query.

Parameters

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.

Return Values

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.

Examples

Example #1 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

Notes

Note:
mysql_info() returns a non-false value for the INSERT ... VALUES statement only if multiple value lists are specified in the statement.
