PHP json_encode and javascript functions

Question

I need to encode a javascript function into a JSON object in PHP.

This:

$function = \"function(){}\";
$message = \"Hello\";

$json = array(   
               


        

Answer 1

json_decode parse the given array to json string, so you can play with it as a string. Just use some unique string to indicate the start and the end of the function. Then use str_replace to remove the quotes.

$function = "#!!function(){}!!#"; 
$message = "Hello";

$json = array(   
  'message' => $message,
  'func' => $function
);
$string = json_encode($json);
$string = str_replace('"#!!','',$string);
$string = str_replace('!!#"','',$string);
echo $string;

The output will be:

{"message":"Hello","func":function(){}}
