Example #1 MysqlndUhConnection::getSqlstate() example
<?php
class proxy extends MysqlndUhConnection {
public function getSqlstate ( $res ) {
printf ( "%s(%s)\n" , __METHOD__ , var_export ( func_get_args (), true ));
$ret = parent :: getSqlstate ( $res );
printf ( "%s returns %s\n" , __METHOD__ , var_export ( $ret , true ));
return $ret ;
}
}
mysqlnd_uh_set_connection_proxy (new proxy ());
$mysqli = new mysqli ( "localhost" , "root" , "" , "test" );
var_dump ( $mysqli -> sqlstate );
$mysqli -> query ( "AN_INVALID_REQUEST_TO_PROVOKE_AN_ERROR" );
var_dump ( $mysqli -> sqlstate );
?>
以上例程会输出:
proxy::getSqlstate(array ( 0 => NULL, )) proxy::getSqlstate returns '00000' string(5) "00000" proxy::getSqlstate(array ( 0 => NULL, )) proxy::getSqlstate returns '42000' string(5) "42000"
