mysql_fetch_object
(PHP 4, PHP 5, PECL mysql:1.0)
mysql_fetch_object — Fetch a result row as an object
Description
Returns an object with properties that correspond to the fetched row and moves the internal data pointer ahead.
Parameters
- result
-
The result resource that is being evaluated. This result comes from a call to mysql_query().
- class_name
-
The name of the class to instantiate, set the properties of and return. If not specified, a stdClass object is returned.
- params
-
An optional array of parameters to pass to the constructor for class_name objects.
Return Values
Returns an object with string properties that correspond to the fetched row, or FALSE if there are no more rows.
mysql_fetch_row() fetches one row of data from the result associated with the specified result identifier. The row is returned as an array. Each result column is stored in an array offset, starting at offset 0.
ChangeLog
| Version | Description |
|---|---|
| 5.0.0 | Added the ability to return as a different object. |

}
mysql_free_result($result);
?>
Example #2 mysql_fetch_object() example

class foo {
public $name;
}
mysql_connect("hostname", "user", "password");

var_dump($obj);
?>
Notes
Note: Performance Speed-wise, the function is identical to mysql_fetch_array(), and almost as quick as mysql_fetch_row() (the difference is insignificant).
Note: mysql_fetch_object() is similar to mysql_fetch_array(), with one difference - an object is returned, instead of an array. Indirectly, that means that you can only access the data by the field names, and not by their offsets (numbers are illegal property names).
Note: Field names returned by this function are case-sensitive.
Note: This function sets NULL fields to the PHP NULL value.
