Question

I have a PHP script that parses an array using the json_encode() method but returns blank

The PHP Code is as follows

$companies = $db->getCustomerNames();
print_r($companies)
if (!empty($companies)){
$jsonstring = json_encode($companies);
echo $jsonstring ; 
}
else{
    echo 'false';
}

• $companies is populated and i can print it out yet

I also have a javascript that looks like this

jQuery.ajax({

    type: "GET",
    url: "http://localhost/myscript.php"
    success: function(msg) {
        companies = jQuery.parseJSON(msg);
        //DO OTHER STUFF WITH companies 
    }
});

• The PHP script connects to a DB and echo the JSON encoded array
• The Javascript gets the array using AJAX so i can use it’s content
• When I hit http://localhost/myscript.php i get a blank page
• Works fine on my local server
• The page is hosted on Yahoo (not sure if it makes a difference)

Answer 1

Try to use function_exist because on some servers json* functions could be disabled or php is configured to not use it
