mysql_info

(PHP 4 >= 4.3.0, PHP 5, PECL mysql:1.0)

mysql_info — Get information about the most recent query

Description

string mysql_info ([ resource $link_identifier ] )

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() was called with no arguments. If by chance no connection is found or established, an E_WARNING level warning 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.

String format: Records: 23 Duplicates: 0 Warnings: 0 
INSERT INTO ... VALUES (...),(...),(...)...
String format: Records: 37 Duplicates: 0 Warnings: 0

Notes

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