The
sql_allfetsel() functions retrieves an array with all of the results of a selection. It accepts the same parameters as the
sql_select() function and is a combined short-cut to replace calling
sql_select() and
sql_fetch_all(). As it stores all of the results in a PHP array, be careful not to exceed the memory limit allowed to PHP if you are dealing with large data volumes.
It accepts 9 parameters:
-#
$select,
-#
$from,
-#
$where,
-#
$groupby,
-#
$orderby,
-#
$limit,
-#
$having,
-#
$serveur,
-#
$option.
The
sql_allfetsel() function is used as shown below:
$all = sql_allfetsel('column', 'table');
// $all[0]['column'] is the column in the first line retrieved
Example
Select all of the
objet /
id_objet pairs associated with a particular document:
if ($liens = sql_allfetsel('objet, id_objet', 'spip_documents_liens', 'id_document=' . intval($id))) {
foreach ($liens as $l) {
// $l['objet'] and $l['id_objet']
}
}
The "Contact avancé" plugin selects all of the emails for the recipients of a message as shown below:
// Retrieve who it was sent to
$destinataire = _request('destinataire');
if (!is_array($destinataire)) {
$destinataire = array($destinataire);
}
$destinataire = array_map('intval', $destinataire);
$mail = sql_allfetsel('email', 'spip_auteurs', sql_in('id_auteur', $destinataire));
