Passing php file to json fail to load data - php

Question

I have tried to add a php file as the source of data for a jquery calendar that uses json as below:
<script>
$(document).ready(function() {
$("#eventCalendarHumanDate").eventCalendar({
eventsjson: 'modules/events/json/event.humanDate.json.php',
jsonDateFormat: 'human'
});
});
</script>
The php file works when i echo variables only but when i connected to the database and looped, it fails and i get the error "error getting json" But running my code separately i get no error from the php file itself.
<?php
$hostname_app_conn = "localhost";
$database_app_conn = "xx";
$username_app_conn = "xx";
$password_app_conn = "";
$app_conn = mysql_pconnect($hostname_app_conn, $username_app_conn, $password_app_conn) or trigger_error(mysql_error(),E_USER_ERROR);
mysql_select_db($database_app_conn, $app_conn );
$query_rs_content = "SELECT * FROM `mod_events_events` WHERE `active`=1 ORDER BY `Id` LIMIT 365";
$rs_content = mysql_query($query_rs_content, $app_conn) or die(mysql_error());
$totalRows_rs_content = mysql_num_rows($rs_content);
header('Content-type: text/json');
echo '[';
$separator = "";
$days = 16;
$i = 1;
echo $separator;
while($row_rs_content = mysql_fetch_assoc($rs_content))
{
echo ' { "date": "'.$row_rs_content['eventday'].'", "type": "'.$row_rs_content['type'].'", "title": "'.$row_rs_content['Title'].'", "description": "'.$row_rs_content['teasertext'].'", "url": "" },';
}
$separator = ",";
echo ']';
?>
thanks in advance.

You should use the json_encode() function, something like this:
//more code above
$array = new array();
while($row_rs_content = mysql_fetch_assoc($rs_content))
{
$array[] = array(
'date' => $row_rs_content['eventday'],
'type' => $row_rs_content['type'],
'title' => $row_rs_content['Title'],
'description' => $row_rs_content['teasertext'],
'url' => '',
);
}
header('Content-type: application/json');
echo json_encode($array);
die();
Most likely you had some character not being escaped properly or something else that was causing it not to be a valid json array so Javascript is dying trying to parse it.
