cursors, and add an example of how to use scrollable cursors (finally!). Add examples for the transaction functions. Correct a typo in the constants. Adopt more reference template goodness throughout. git-svn-id: https://svn.php.net/repository/phpdoc/en/trunk@178958 c90b9560-bf6c-de11-be94-00142212c4b1

<function>PDOStatement::fetchAll</function> 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.
