WampServer

It's means.

when I write: echo "Hola";

In the web page shows me: echo "Hola;

I don't understand, because It has to show "Hola" and not the completly script.

Please, I need some help! Thanks.

Its a mistake.

Either the script file does not have an .php extension

Or

You are double clicking on the file in explorer and not as you should be using the browser and entering the url
`localhost/project1/test.php`

Do you have <?php before your 'echo' command?

```
<?php
echo "Hola";
```
or just
```
echo "Hola";
```

Also check whether you're using short open tags ( e.g. <? instead of <?php ) and whether they're enabled in PHP (Left clickWampManager -> PHP -> PHP Settings )
