I could not stand by and see that mangled code. Here is what I think you meant to do.

<?php
function createButton()
{
    echo '<button onclick="testFunction()">My Button</button>';
}

function my_php_function()
{
    echo '<script>
    function check()
    {
        alert("Works");
    }
    function testFunction() {
      check();
    }
  </script>';
}
add_action( 'wp_footer', 'my_php_function' );
