mysql_fetch_object — Fetch a result row as an object
This extension is deprecated as of PHP 5.5.0, and will be removed in the future. Instead, the MySQLi or PDO_MySQL extension should be used. See also MySQL: choosing an API guide and related FAQ for more information. Alternatives to this function include:
$result
[, string $class_name
[, array $params
]] )Returns an object with properties that correspond to the fetched row and moves the internal data pointer ahead.
resultThe result resource that is being evaluated. This result comes from a call to mysql_query().
class_nameThe 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.
Returns an object with string properties that correspond to the
fetched row, or FALSE if there are no more rows.
| Version | Description |
|---|---|
| 5.0.0 | Added the ability to return as a different object. |
Example #1 mysql_fetch_object() example
<?php
mysql_connect("hostname", "user", "password");
mysql_select_db("mydb");
$result = mysql_query("select * from mytable");
while ($row = mysql_fetch_object($result)) {
echo $row->user_id;
echo $row->fullname;
}
mysql_free_result($result);
?>
Example #2 mysql_fetch_object() example
<?php
class foo {
public $name;
}
mysql_connect("hostname", "user", "password");
mysql_select_db("mydb");
$result = mysql_query("select name from mytable limit 1");
$obj = mysql_fetch_object($result, 'foo');
var_dump($obj);
?>
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
NULLvalue.
