mysql_fetch_object — Fetch a result row as an object
Questa enstensione deprecata da PHP 5.5.0, e sarà rimossa in futuro. Al suo posto, usare l'estensione MySQLi o PDO_MySQL. Vedere anche la guida MySQL: scelta dell'API e le FAQ relative per ulteriori informazioni. Le alternative a questa funzione includono:
mode as PDO::FETCH_OBJ
Returns an object with properties that correspond to the fetched row and moves the internal data pointer ahead.
resultThe risultato resource che che viene calcolato. Questo risultato deriva dal una chiamata a 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.
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);
?>Nota: Performance
Speed-wise, the function is identical to mysql_fetch_array(), and almost as quick as mysql_fetch_row() (the difference is insignificant).
Nota:
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).
Nota: I nomi dei campi restituiti da questa funzione sono case-sensitive.
Nota: Questa funzione imposta i campio NULL al valore PHP
