• PHP - Dynamic Content

  Posted on April 4th, 2009 admin No comments

  Dynamic content in PHP basically means that the content changes. For example: If a visitor to your site submitted a comment you could have your script to output the date and time of the comment back to the user. As the date and time will be different in every comment it’s known as dynamic content. Let’s use the date function:

  <?php

  echo “<p>Comment processed. Date and time processed:  “;

  echo date (’H:i, jS F Y’);

  echo “</p>”;

  ?>

  The above will output to the browser: Comment processed. Date and time processed: 18:20, 4th April 2009

  Quite easy to be honest and PHP can be used in many ways like this!

• PHP Comments (using single-line and multi-line comments)

  Posted on April 4th, 2009 admin 1 comment

  To make our lives easier we can use comments to let yourselves or other programmers know what a piece of code is doing. These are very much like notes as it describes what something is doing. This is essential in PHP when you look back at the code.

  The PHP interpreter will ignore any comments as long as you put these comments in the correct format. There are two types of comments. One called single-line comments and one called multi-line comments which are both self explanatory really!

  To insert a single line comment all you have to do is insert the ‘//’ after a line of code. For example:

  echo ‘<p>Hello world.</p>’; // This is a statement that sends to the browser Hello world.

  To insert a multi-line comment you have to insert your comment between these two tags: /* and */ anywhere in your code (most probably at the start or end of your script). For example:

  /* Created by: Nathan

  Last modified: 4th April 2009

  Script purpose: Process comments

  */

  Inserting comments is something you should get aquainted to as it can really help finding out what bits of code does what.

  All PHP scripts are contained within PHP tags.

  <?php and ?>

  e.g.      <?php echo ‘<p>Hello world.</p>’; ?>

  What does the echo command do? The echo command prints the string passed to it to the browser. The above example will show ‘Hello world’ in the browser when opened.

  Another example:

  echo ‘I love ‘;

  echo ‘PHP’;

  will output ‘I love PHP’ in the browser. This is all simple stuff but it does get more complex!
