Error updating database php

For many people, the main reson for learning a scripting language like PHP is because of the interaction with databases it can offer.In this tutorial I will show you how to use PHP and the My SQL database to store information on the web and include it into your website.

Isto simplismente significa que ela está disponível em todos escopos pelo script.

It will allow you to store names with their addresses, e-mail and phone numbers.

You will be able to update records and search the database.

Não há necessidade de fazer global $variable; para acessá-la dentro de uma função ou método.

Be carefull with $_SESSION array elements when you have the same name as a normal global. But setting $wppa['elm1'] to another value or referring to it gives unpredictable results, maybe 'value1', or 'newvalue1'.

To do this I will be using an example all the way through.

As you use this tutorial, you will learn how to create a web based contact management program.Freedom2Surf are a free (banner supported) web host and support PHP and have My SQL installed.Host Rocket are an excellent web host and can offer you 300MB of space with PHP, My SQL and loads of other extras for under a month.The following example leads to unpredictable behaviour of the $wppa array elements, some are updated by normal code, some not, it is totally unpredictable what happens. The most strange behaviour is that not all elements of $wppa[xx] show up as $_SESSION['wppa'][xx].If you are using a session variable as a token to use as a handshake on next page load and the token updates on the new page load, but they mysteriously will not match and there is no obvious explanation.Although all the database administrative options can be done through PHP scripts, I strongly suggest installing a copy of PHPMy Admin on your server.
