We could redirect webpage by using HTML meta tag. The syntax of the meta is:

Editor’s note: In my past post Redirect page using PHP function header(), I talked about how to redirect page with header() function. To refresh a page, by using the same function and redirect to the page to itself, then it has the refresh effect.

We use HTML form a lot for the user to input data and process those data from a PHP file, but with the standard code of a HTML form:

In some cases such as login system, the HTML form should contains a text field for the user to type in the password. But when the user types in the password, other might see the password from behind the user. To avoid from this happening, a password text field is needed. A password text field works when the user type the password into the text field, every character will turn into *.

Editor’s note: To use the records in the MySQL database as the “values and display text” of the check box is a good idea for the administrator because he/she can add, update or delete check box’s items from the MySQL database, without touching the HTML source.

Editor’s note: There is a function in PHP to check the IP address of a host. It is called “gethostbyname()“. We could use it to check the IP address of a website. Steps are very simple: Put the website address into the function, for example: gethostbyname(www.phpsuperblog.com); and print the result out and then the IP address of the website would appear.
