GET and POST methods
Does anyone know exactly when to use the GET and when to use the POST methods, why and why not?

Thanks in advance.

GET is used for when the variables are in the URL. For example,

http://www.programmerstalk.net/index...iable=my_value

would give you $_GET['my_variable'].

POST is used when data is submitted via a form through tags like

<input type="text" name="my_variable" value="my_value" />

Then, you'd have $_POST['my_variable']

Security reasons my also influence your choice between get and post

$_GET, your variables from the form are passed through the URL, there are some security issues related to this as the user can bookmark this page.

&_POST, less of a security risk because there is no URL passing your data from form to server, also the user can't bookmark the submitted page.

I usauly use $_GET for testing purposes to see if the variable are passed through the URL, when variables are pass I change to $_POST.

For a more complete recommendation on when to use URL versus form-submitted values, do a search for the REST methodology.

There is nothing inherently wrong with GET variables provided you check session status and use them in accordance with the REST methodology. In fact, they can be very helpful for your users and for indexing.
