When solving the following trigonometric equation, the solution set obtained is:
Solve[{5 (Sin[5 x + \[Phi]] - Sin[x]) == 0,
0 <= \[Phi] <= 2 \[Pi]}, x, Reals]

How to further simplify and combine solution sets of trigonometric equations to obtain the following solution form?
{{x -> ConditionalExpression[
1/6 (\[Pi] - \[Phi] +
2 \[Pi] ConditionalExpression[1, \[Placeholder]]),
ConditionalExpression[1, \[Placeholder]] \[Element] Integers &&
0 <= \[Phi] <= 2 \[Pi]]}, {x ->
ConditionalExpression[
1/4 (-\[Phi] + 2 \[Pi] ConditionalExpression[1, \[Placeholder]]),
ConditionalExpression[1, \[Placeholder]] \[Element] Integers &&
0 <= \[Phi] <= 2 \[Pi]]}}
