The Zend API contains macros that can be used to convert a *zval to a  value. These macros are defined in the Zend header file, zend_API.h in the  Zend directory of your PHP build directory. Some of these attributes can be  used with the statement attribute handlers such as the PDO_ATTR_CURSOR and  PDO_ATTR_CURSOR_NAME. See the statement attribute handling functions for  more information. </p></div><hr /><div style="text-align: center;"> <div class="prev" style="text-align: left; float: left;"><a href="internals2.pdo.pdo_stmt_t.html">pdo_stmt_t definition</a></div> <div class="next" style="text-align: right; float: right;"><a href="internals2.pdo.error-handling.html">Error handling</a></div> <div class="up"><a href="internals2.pdo.html">PDO Driver How-To</a></div> <div class="home"><a href="index.html">PHP Manual</a></div></div></body></html>
