mysql_fetch_object

Name

mysql_fetch_object — Fetches a row of data from a result handle and returns it as an object.

Synopsis

object mysql_fetch_object(result handle[, result_type]);
mysql result result handle: Result handle returned by mysql_db_query() or mysql_query()
int result_type (optional): Result explanation goes here

Returns

Object containing one row of query data; FALSE when out of data or on error

Description

mysql_fetch_object() retrieves a row of data from a result handle returned by mysql_db_query() or mysql_query() . The data is returned as an object. After the data is retrieved, the result handle's internal pointer is advanced one position.

The column names are used as property names for the object. If column names are duplicated, the data in the last column in the query sharing the name overwrites the value of the other properties. To access data from these types of queries, use mysql_fetch_row() .

Note

Despite the added functionality, mysql_fetch_object() is not significantly slower than mysql_fetch_row() ; in fact, mysql_fetch_array() , mysql_fetch_assoc() , mysql_fetch_object() , and mysql_fetch_row() share a common underlying function in the source code.

Version

PHP 3+, PHP 4+

Example

Example 808. Demonstrate how mysql_fetch_array() retrieves data from a query handle

<pre>
<?php
// Included code that connects to a MySQL server and sets a default database
// See the MySQL Functions chapter introduction for the source code for the file
include ('mysql_connect.inc.php');

// Make a simple SELECT query
$query = "SELECT * FROM user ORDER BY login";
$mysql_result = @ mysql_query ($query)
    or die ("Query '$query' failed with error message: \"" . mysql_error () . '"');

// Show the default behavior of mysql_fetch_array()
// Grab one row from our result handle
$row = @ mysql_fetch_object ($mysql_result)
    or die ("Try a different query - this one did not return any rows.");

// Display the contents of the object returned by mysql_fetch_object()
print_r ($row);
?>
</pre>
