Return Values
The return value of this function on success depends on the fetch type. In
all cases, Examples
Example #1 Fetching rows using different fetch styles
<?php The above example will output: PDO::FETCH_ASSOC: Return next row as an array indexed by column name Array ( [name] => apple [colour] => red ) PDO::FETCH_BOTH: Return next row as an array indexed by both column name and number Array ( [name] => banana [0] => banana [colour] => yellow [1] => yellow ) PDO::FETCH_LAZY: Return next row as an anonymous object with column names as properties PDORow Object ( [name] => orange [colour] => orange ) PDO::FETCH_OBJ: Return next row as an anonymous object with column names as properties kiwi Example #2 Fetching rows with a scrollable cursor
<?php The above example will output: Reading forwards: 21 10 5 16 0 5 19 20 10 Reading backwards: 19 20 10 16 0 5 21 10 5 Example #3 Construction order When objects are fetched via PDO::FETCH_CLASS the object properties are assigned first, and then the constructor of the class is invoked. If PDO::FETCH_PROPS_LATE is also given, this order is reversed, i.e. first the constructor is called, and afterwards the properties are assigned.
<?php The above example will output something similar to: I am Alice. I am Alice. I don't have a name yet. I am Bob. See Also
