从Oracle数据库返回Json

Question

如何使用php从Oracle返回Json格式？我做了这个并用firebug进行了调试，没有任何错误，它没有返回任何内容......但它已经完成了打印！

<?php

$user = "username";
$pass = "password";
$host = "myhost/myservicename";

$conn = oci_connect($user, $pass, $host);
$sql  = oci_parse($conn, "SELECT * FROM emp WHERE rownum <100");

oci_execute($sql);

$rows = array();
while($r = oci_fetch_assoc($sql)) {
$rows[] = $r;
 }
$locations =(json_encode($rows));
echo 'done!';
?>

Answer 1

响应就是您打印页面的内容。

所以将'done!'更改为$locations
