dbx_fetch_row

(PHP 5 <= 5.0.4)

dbx_fetch_row -- Fetches rows from a query-result that had the DBX_RESULT_UNBUFFERED flag set

Description

mixed dbx_fetch_row ( object result_identifier )

dbx_fetch_row() returns a row on success, and 0 on failure (e.g. when no more rows are available). When the DBX_RESULT_UNBUFFERED is not set in the query, dbx_fetch_row() will fail as all rows have already been fetched into the results data property.

As a side effect, the rows property of the query-result object is incremented for each successful call to dbx_fetch_row() .

例子 1. How to handle the returned value

<?php
$result = dbx_query ( $link , 'SELECT id, parentid, description FROM table' , DBX_RESULT_UNBUFFERED );

echo "<table>\n" ;
while ( $row = dbx_fetch_row ( $result )) {
    echo "<tr>\n" ;
    foreach ( $row as $field ) {
        echo "<td>$field</td>" ;
    }
    echo "</tr>\n" ;
}
echo "</table>\n" ;
?>

The result_identifier parameter is the result object returned by a call to dbx_query() .

The returned object contains the same information as any row would have in the dbx_query result data property, including columns accessible by index or fieldname when the flags for dbx_guery were set that way.
