How to zoom in while using an iPhone?

I like to use the Internet on my iPhone, but a lot of the time I have difficulty reading the words on the screen, because they're so small. Is there any way that I can magnify the words on the screen?

Use your index finger and thumb on the same hand.start with them close together then spread them apart.

Put your pointer finger and thumb together on the screen and separate them then do the oppostie to do the opposite.

Pinching and Double Tapping
If you want to zoom in on a particular section of a web page, simply double tap it (tap twice in quick succession on the same part of the screen) with your finger. This enlarges that section of the page. The same double tap zooms out again.

Multitouch
If you want more control over what you're zooming in on or how much zooming you do, use the multitouch feature.

Put your index finger together with your thumb and place them on the part of the iPhone's screen that you want to zoom in on. Then, drag your fingers apart, sending each one towards the opposite edge of the screen. This zooms in on page. The text and images appear blurry for a moment and then the iPhone makes them crisp and clear again. To zoom out of the page, put your fingers at opposite ends of the screen and drag them towards each other, meeting in the center of the screen.

Put your fingers on the screen and separate them as if you are opening it and making a hole. Try it and you'll see.
