json_encode is returning NULL?
I'm having a strange problem with
json_encode() in php. Pretty simple code:
$content = json_encode(array('content1' => $arm_length, 'content2' => $body_length)); echo $content;
$body_length variables contain the HTML markup for two select dropdown menus. My problem is when it
echo's out it show's
content2. If I take the
json_encode() away and just do
print_r($content) it shows all the data as it should be.
Does anyone know what's happening here? Is there certain data that can't be parsed into JSON? I've done this a few times now using Ajax/PHP and never had any problems.
Cheers for any help with this.
