String ob_get_close()

:params
return value : the current buffer's contents

:content
Returns the current output buffer's contents and discards the buffer, switching back to the previous one on the stack. This is the usual way to capture rendered output for post-processing.

:example
ob_start();
print("hello ");
print("world");
String html = ob_get_close();
print("captured ", html.length(), " chars: ", html, "\n");
