Question

I’ve some problem retrieving json information with a PHP.

I’ve created a simple php page that returns a json:

$data = array(
    'title' => 'Simple title'
);
print json_encode($data);

And in another page I try to get that array as an object:

$content = file_get_contents($url);
$json_output = json_decode($content, true); 

switch(json_last_error())
{
    case JSON_ERROR_DEPTH:
        echo ' - Maximum stack depth exceeded';
        break;
    case JSON_ERROR_CTRL_CHAR:
        echo ' - Unexpected control character found';
        break;
    case JSON_ERROR_SYNTAX:
        echo ' - Syntax error, malformed JSON';
        break;
    case JSON_ERROR_NONE:
        echo ' - No errors';
        break;
}

The problem is that there is an error with this approach: I receive a “JSON_ERROR_SYNTAX” because after “file_get_contents” function I have an unknown character at the beginning of the string.

If I copy/paste it on Notepad++ I didn’t see:

{"title":"Simple title"}

but I see:

?{"title":"Simple title"}

Could someone help me?

Make sure both your scripts have same encoding – and if it’s UTF make sure they are without Byte Order Mark (BOM) at very begin of file.
