PDOStatement to json

Question

How would I convert a PDOStatement to json?

Is there lib out there to do this?

EDIT: I need to jsonify a PDO::FETCH_OBJ. Sorry, thanks for all of the responses.

json_encode does not have the ability to jsonify a PDO::FETCH_OBJ.

Thanks.

Answer 1

Use the fetchAll() method of the PDOStatement to retrieve an array of the values, and then pass that to json_encode().

$resultJSON = json_encode($stmt->fetchAll(PDO::FETCH_ASSOC));

Answer 2

$array = $statement->fetchAll( PDO::FETCH_ASSOC );
$json = json_encode( $array );

Answer 3

You can use the inbuilt php function json_encode() http://php.net/manual/en/function.json-encode.php

To encode the statement use something like this:

<?php
$pdo=new PDO("mysql:dbname=database;host=127.0.0.1","user","password");
$statement=$pdo->prepare("SELECT * FROM table");
$json=json_encode($statement);
?>

To encode just the results use something like

<?php
$pdo=new PDO("mysql:dbname=database;host=127.0.0.1","user","password");
$statement=$pdo->prepare("SELECT * FROM table");
$results=$statement->fetchAll(PDO::FETCH_ASSOC);
$json=json_encode($results);
?>
