mysql_error -- Returns the text of the error message from previous MySQL operation
Description
string mysql_error ( [resource link_identifier] )
Returns the error text from the last MySQL function.
Errors coming back from the MySQL database backend no longer
issue warnings. Instead, use mysql_error() to
retrieve the error text. Note that this function only returns the
error text from the most recently executed MySQL function (not
including mysql_error() and
mysql_errno()), so if you want to use it, make
sure you check the value before calling another MySQL function.
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 the error text from the last MySQL function, or
'' (empty string) if no error occurred.
