What should I do if I want to warp my text and create and ARC with it?

Select the warped text menu from the option bar and set the style to arc is the right answer.
To warp text in photoshop, use the following steps.

- Select the Text tool and type your text.
- After selecting the text layer and type tool active, click on the "create warped text" icon in the tool bar.
- In the wrap text window, select the "Arc" style, check the horizontal option and set the bend value to about 20% then click OK.
- Selecting the curved text tool from the tool window will not create an arc, you sure can curve a text in photoshop, placing each letter one at a time will take much time.
