Example #1 MysqlndUhConnection::getErrorString() example

<?php
class proxy extends MysqlndUhConnection {
 public function 
getErrorString($res) {
   
printf("%s(%s)\n"__METHOD__var_export(func_get_args(), true));
   
$ret parent::getErrorString($res);
   
printf("%s returns %s\n"__METHOD__var_export($rettrue));
   return 
$ret;
 }
}
mysqlnd_uh_set_connection_proxy(new proxy());

printf("connect...\n");
$mysqli = new mysqli("localhost""root""""test");
printf("query...\n");
$mysqli->query("WILL_I_EVER_LEARN_SQL?");
printf("errno...\n");
var_dump($mysqli->error);
printf("close...\n");
$mysqli->close();
?>

The above example will output:

 connect... proxy::getErrorString(array ( 0 => NULL, )) proxy::getErrorString returns '' query... errno... proxy::getErrorString(array ( 0 => NULL, )) proxy::getErrorString returns 'You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near \'WILL_I_EVER_LEARN_SQL?\' at line 1' string(168) "You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near 'WILL_I_EVER_LEARN_SQL?' at line 1" close...
