Example #1 MysqlndUhConnection::listFields() example
<?php
class proxy extends MysqlndUhConnection {
public function listFields($res, $table, $pattern) {
printf("%s(%s)\n", __METHOD__, var_export(func_get_args(), true));
$ret = parent::listFields($res, $table, $pattern);
printf("%s returns %s\n", __METHOD__, var_export($ret, true));
return $ret;
}
}
mysqlnd_uh_set_connection_proxy(new proxy());
$mysql = mysql_connect("localhost", "root", "");
mysql_select_db("test", $mysql);
mysql_query("DROP TABLE IF EXISTS test_a", $mysql);
mysql_query("CREATE TABLE test_a(id INT, col1 VARCHAR(255))", $mysql);
$res = mysql_list_fields("test", "test_a", $mysql);
printf("num_rows = %d\n", mysql_num_rows($res));
while ($row = mysql_fetch_assoc($res))
var_dump($row);
?>
以上例程会输出：
proxy::listFields(array ( 0 => NULL, 1 => 'test_a', 2 => '', )) proxy::listFields returns NULL num_rows = 0
