dbx_fetch_row

(PHP 5 < 5.1.0, PECL dbx >= 1.1.0)

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

说明

dbx_fetch_row ( object $result_identifier ) : mixed

dbx_fetch_row() fetches rows from a result identifier that had the DBX_RESULT_UNBUFFERED flag set.

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().

参数

result_identifier

A result set returned by dbx_query().

返回值

Returns an object on success that 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_query() were set that way.

Upon failure, returns 0 (e.g. when no more rows are available).

范例

Example #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";
?>

Use this function ONLY if you are using:
DBX_RESULT_UNBUFFERED

and make sure the database you're using will allow DBX_RESULT_UNBUFFERED as a flag on the connect line.

I spent 2 days trying to figure out WHY I couldn't use the dbx_fetch_row() function.  Too many languages!
