WordPress Expert Questions And Answers

1⟩ Described 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.

3⟩ How 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.

5⟩ If the variable $a is equal to 5 and variable $b is equal to character a, what's the value of $$b?

Answer #1

100, it's a reference to existing variable.

Answer #2

5, $$b acts as a variable variable and would be the same as writing $a.

Answer #3

$a=5; $b="a"; echo $$b; it will be 5 not 100;

6⟩ Why doesn't the following 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.

7⟩ Would you 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.

8⟩ Is a 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.

12⟩ Will you have the ability to update my own content?

That depends on the site/project itself. We have created sites where almost every aspect could be edited by the client (content, navigation, photos, forms, etc) and others where it was a simple setup to allow for the main content areas to be edited. This is something we will discuss when planning the project and determine what your need will be. At the very least you will be able to edit the site content yourself and the ability to add/remove photos.

13⟩ Tell me do I need to know any programming to make updates?

To initially setup a site and customize it you will, though you don't need to worry about that because that is what we are doing for you. Once the site is setup we will train you on how to perform the updates (very simple) and you will be good to go. In order to perform the content updates you may need in the future you will not need to know any programming at all. I compared it earlier to using Microsoft Word and it really is that easy!

Forget about having to hire a programmer to make simple text updates on your site from now on, you can go in and do it yourself in a matter of minutes.

It's how they handle failures. If the file is not found by require(), it will cause a fatal error and halt the execution of the script. If the file is not found by include(), a warning will be issued, but execution will continue.

17⟩ Would I use print "$a dollars" or "{$a} dollars" to print out the amount of dollars in this example?

In this example it wouldn't matter, since the variable is all by itself, but if you were to print something like "{$a},000,000 mln dollars", then you definitely need to use the braces.
