Hi there,

For AJAX-calls I'm buffering my output, check for errors and if an error occurred print a custom, json-formatted error message. If everything works as expected, the buffered output is printed. I don't send any headers in my script, but for some reason if an error occurs and my buffering's on, I get a "500 (Internal Server Error)" as response-header. If I switch off my custom error-handling an the same error is thrown, PHP responds with a "200 OK".. How can that be?

My code's this:

// Suppress normal error output
ini_set('display_errors', 0);

// buffer Output
ob_start();

// When the PHP-Script's ended check for errors an print buffered content or an error message
register_shutdown_function(function() {

$error = error_get_last();

if($error) {
ob_end_clean();
header('Content-type: application/json');
echo "{'some': 'json here'}";
}else{
ob_end_flush();
}

});
