Before you start coding your application with PHP or whatever remember to test out your MySQL in your MySQL GUI such as SQLYOG or even the CLI

What are the advantages?

* You don’t have to worry about the Script/MySQL syntax clashes (quoting etc)
* You only have to think MySQL and not say PHP as well
* You can see the data produced or not produced
* You can test your concepts

To save space and make your CSS files easier to read I recommend using shorthand syntax to declare several properties in a single declaration. How the available shorthand properties are used is described in my article Efficient CSS with shorthand properties, so I’m referring you to that instead of going into any details here.

Although the names are much alike, JavaScript is primarily a scripting language for use within HTML pages, while Java is a real programming language that does quite different things from JavaScript. In addition Java is much harder to learn. It was developed by Sun for use in pretty much anything that needs some computing power.

JavaScript was developed by Brendan Eich, then working at Netscape, as a client side scripting language (even though there’s no fundamental reason why it can’t be used in a server side environment).

Originally the language was called Live Script, but when it was about to be released Java had become immensely popular (and slightly hypey). At the last possible moment Netscape changed the name of its scripting language to “JavaScript”. This was done purely for marketing reasons. Worse, Eich was ordered to “make it look like Java”. This has given rise to the idea that JavaScript is a “dumbed-down” version of Java. Unfortunately there’s not the slightest shred of truth in this story.

Java and JavaScript both descend from C and C++, but the languages (or rather, their ancestors) have gone in quite different directions. You can see them as distantly related cousins. Both are object oriented (though this is less important in JavaScript than in many other languages) and they share some syntax, but the differences are more important than the similarities.

If you are a C++ or Java programmer you will be surprised by some of JavaScript’s features. Since I don’t have any previous programming experience, the differences are not described on this site. The best you can do is buy David Flanagan, “JavaScript, the Definitive Guide”, 5th edition, O’Reilly, 2006. In this book the differences between C++/Java and JavaScript are clearly explained. I co–edited a few chapters of this book.

Using a special syntax is a way to tell Google that you want to restrict your searches to certain elements or characteristics of Web pages. Google has a fairly complete list of its syntax elements at www.google.com/help/operators.html. Here are some advanced operators that can help narrow down your search results.

Intitle: at the beginning of a query word or phrase (intitle:”Three Blind Mice”) restricts your search results to just the titles of Web pages.

Intext: does the opposite of intitle:, searching only the body text, ignoring titles, links, and so forth. Intext: is perfect when what you’re searching for might commonly appear in URLs. If you’re looking for the term HTML, for example, and you don’t want to get results such as www.mysite.com/index.html, you can enter intext:html.

Link: lets you see which pages are linking to your Web page or to another page you’re interested in.

Try using site: (which restricts results to top-level domains) with intitle: to find certain types of pages. For example, get scholarly pages about Mark Twain by searching for intitle:”Mark Twain”site:edu. Experiment with mixing various elements; you’ll develop several strategies for finding the stuff you want more effectively. The site: command is very helpful as an alternative to the mediocre search engines built into many sites.

When PHP is tightly intertwined with HTML it can be awful to lay your eyes upon. Many years ago, while with a previous employer, the development staff and I believed it was a sin to use straight HTML in PHP files. We believed every file ending in a .php extension could only contain PHP. In retrospect, I don’t know why we ever did this, but I have seen other groups adhere to such rules as well. This style made what should have been simple HTML far more complex that it had to be.

Over the past few years the style in which developers are writing PHP to output HTML has shifted quite a bit.

Example 1: No Alternative Syntax, and a Lot of PHP.

<?php
echo “<table size=\”100\”>\n”;
echo ” <tbody>\n”;

if($displayResults) {

while($row = mysql_fetch_assoc($result)) { ?>
echo “<tr>\n”;
echo “<td>” . htmlentities($row['id']) . “</td>\n”;
echo “</tr>\n”;
}

}

echo “</tbody>\n”;
echo “</table>\n”;

?>

This is typical to what I’ve seen in a number of PHP applications. Though this is a simple example, I am sure you can appreciate how this method of outputting mostly html can grow out of control. It requires significantly more developer brain power to determine the code’s purpose than the example below.

Example 2: Less PHP Paired With Alternative Syntax

<table>
<tbody>
<?php if($displayResults): ?>
<?php while($row = mysql_fetch_assoc($result)): ?>
<tr>
<td><?php echo htmlentities($row['id']); ?></td>
</tr>
<?php endwhile; ?>
<?php endif; ?>
</tbody>
</table>

Here in example 2 the same functionality is achieved by using PHP alternate syntax and less output statements. As you can see, this fashion of interweaving PHP and HTML can go a long way to increase code readability.

A PHP scripting block usually starts with . The best thing about PHP scripting block is that you can place it anywhere in the document. placed anywhere in the document.

On servers with shorthand support enabled you can start a scripting block with .

It is recommend that you use the standard form

< html >
< body >

< ? php
echo “Hello World”;
? >

< /body >
< /html >< /em >

Every line in PHP ends with a semi-colon. The two basic output text in PHP are: Echo and Print.
