Function ereg_replace() is deprecated - How to clear this bug?

Question

I have written following PHP code:

$input="menu=1&type=0&";

print $input."<hr>".ereg_replace('/&/', ':::', $input);

After running above code, it gives following warning,

Deprecated: Function ereg_replace() is deprecated

How can I resolve this warning.

Switch to preg_replace^Docs and update the expression to use preg syntax (PCRE) instead of ereg syntax (POSIX) where there are differences^Docs (just as it says to do in the manual for ereg_replace^Docs).
