[php-src] Issue #9726: PHP PDO connects to MySQL using PDO:: CURSOR_ Invalid SCROLL cursor, unable to scroll to get the desired row

Issue: https://github.com/php/php-src/issues/9726 Author: 1107012776 ### Description For example, I have a table with two fields: id and value. I inserted nearly 100k rows into this table. I want to use the scrollable cursor. I wrote the following code: ``` $sql = 'SELECT id FROM cursor_ test;'; $stmt = $dbh->prepare($sql, array(PDO::ATTR_CURSOR => PDO::CURSOR_SCROLL)); $stmt ->Execute (); $row = $stmt->fetch(PDO::FETCH_ASSOC, PDO::FETCH_ORI_ABS, 3); var_ dump($row['id']); // 1, the expected value is 3 ``` What did I do wrong? ### PHP Version PHP5.6.25 ### Operating System window7
