string mysql_info(resource $link_identifier = NULL)
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()
Returns detailed information about the last query.
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
- resource $link_identifier [ = NULL]: 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_WARNINGlevel error is generated.
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 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.
