PHP - Moved: Wide Space In Between Contents Using <td> In Php Code

Hi All,

I'm having a major mind blank, and can't find anything in the previous posts resolving what I'm after.

I'm setting

$searchtext = $_POST['searchtext'];

I want to check $seachtext is not null.

I've seen isset($searchtext) but it doesn't solve my problem.

Basiclaly; I want an if statement to say if(isset($searchtext)) {......}

Thoughts?

Greetings all,

I like to make a config.php file and place it outside my document root for security. I do this all the time. Then just inlcude the config in any file that I need information for.

include('../includes/config.php');

This works most of the time for any DB connection information a piece of code might need. However, sometimes I like to place all my functions in a file called functions.php to keep them separate and have a single place to work with them.

I have not done any coding in about two years and just started back and for the life of me I can't get any connection attempt inside any of my functions to use the DB connection info from the config.php even if I include the file right inside the functions.php at the top. Even when I put all my functions inside the config file itself they still have no access to the connection vars.

I remember that I used to be able to use a global so some type to do this.  The important part is getting DB connection access to any functions that I write.

Here is an example of a plain config that I might start with;

//* Database connection information.. *//

$DBHost="localhost"; //* Database Hostname
$DBName="some_db"; //* Database Name
$DBUser="some_user"; //* Database Username
$DBPass="some_pass"; //* Database Password

$db = mysql_connect($DBHost, $DBUser, $DBPass);
mysql_select_db($DBName);



Can someone show me where I'm going wrong and the modern excepted method of doing this?

I would greatly appreciated it!!

Thank you.

What is the best practice for using site-wide constants in a class?

E.g. COMPANY_NAME is set in a config file and used on many pages. How would it be best to use this in a class. I'm guessing just calling COMPANY_NAME anywhere in the class would not be considered best practice.

Thanks.

I have a table with postcodes in it. At some point some of the codes will be entered with spaces (LA12 5TH) and some without (LA17HU) what i need is a function to check if there is a space, if not - count back 3 characters from the end of the string and insert a space.

I don't know which string function to use - looked at pad but that seems to be for either end of string and not the middle - any ideas?
