Answer 1

反斜杠可避免引号：

echo "<a href='#false' onclick=\"load_page('piano_programs.php')\">Piano Programs</a>";

Answer 2

You need to add slashes before onclick's two double quotes and move your single quote to the right side of .php .

echo "<a href='#false' onclick=\"load_page('{$program_name}.php')\">Piano Programs</a>";

I like to curly-bracket my variables so that they stand out in my editor and so that they don't get mixed up with the text that immediately follows.
