PDOStatement::fetchAll -- Returns an array containing all of the result set rowsAtenção |
Esta função é EXPERIMENTAL. Isso quer dizer que o comportamento desta função e seu nome, incluindo TUDO o que está documentado aqui pode mudar em futuras versões do PHP, SEM QUALQUER NOTIFICAÇÃO. Esteja avisado, e use esta função por sua própria conta e risco. |
Controls the contents of the returned array as documented in PDOStatement::fetch(). Defaults to PDO_FETCH_BOTH.
PDOStatement::fetchAll() returns an array containing all of the remaining rows in the result set. The array represents each row as either an array of column values or an object with properties corresponding to each column name.
Using this method to fetch large result sets will result in a heavy demand on system and possibly network resources. Rather than retrieving all of the data and manipulating it in PHP, consider using the database server to manipulate the result sets. For example, use the WHERE and SORT BY clauses in SQL to restrict results before retrieving and processing them with PHP.
