31 WordPress Support Officer Questions and Answers:

1 :: Described what is WordPress?

The WordPress web site defines WordPress as "web software you can use to create a beautiful website or blog. " That describes it in the simplest form possible though I will try to expand on that. WordPress is the platform that we currently use for the majority of all client web sites. It was originally used for blogs but has since expanded to be used for full web sites, both personal and business. The main reason people prefer using WordPress now is that it is extremely easy to use, even for a beginner. Once the site is setup (that is where we come in) you will be able to update the content of your web site yourself, without having to know any programming at all! If you are able to create a document in Microsoft Word then you will be bale to update your web site, it is that easy.
WordPress also allows your site to be expanded with incredible features thanks to the many plugins available. We will determine at the start of the project what you will need and everything will be setup and customized for you.

2 :: Is web site on WordPress secure?

Out of the box WordPress is secure and you should not have to worry about any problems with your site. While we agree with that sentiment it does not stop us from taking extra steps to be positive your site will be secure. Part of the process of creating your site involves us taking extra measures to be sure your site will be secure for you. There are many things we will do that you will never need to understand, but unlike many design firms we will not just do a basic install and walk away. This will help prevent attacks against your web site (something that is not very common to begin with though).
There is a common myth that WordPress web sites are more prone to be attacked or hacked than a normal web site. After working on nothing but WordPress sites and blogs for the past three years I have only had to go in and repair a single site and that was due to a problem with the host of the site and not the site itself. Major businesses now use WordPress for their web sites, I am sure they would not do so if they felt it was not secure.

4 :: How to initialize strings with single quotes or double quotes?

Since the data inside the single-quoted string is not parsed for variable substitution, it's always a better idea speed-wise to initialize a string with single quotes, unless you specifically need variable substitution.

5 :: <?php
$str = 'Hello, there.nHow are you?nThanks for visiting Us';
print $str;
?>
Why does not given code print the newline properly?

<?php
$str = 'Hello, there.nHow are you?nThanks for visiting Us';
print $str;
?>
Because inside the single quotes the n character is not interpreted as newline, just as a sequence of two characters - and n.

6 :: How to come code:
<?php print "Contents: $arr[1]"; ?>
works, but
<?php print "Contents: $arr[1][2]"; ?>
doesn't for two-dimensional array of mine?

Any time you have an array with more than one dimension, complex parsing syntax is required. print "Contents: {$arr[1][2]}" would've worked. /> - Yes.
