[Year 12 SofDev] Records in PHP

[Kevork Krozian]

Hi Folks,
 
This is where it gets interesting to store a record in PHP ( in memory or in a file ).
See http://www.designdetector.com/archives/04/10/FlatFileDatabaseDemo.php#database. Basically it is a very painful process without a database.
An associative array can represent a record. And an array of associative arrays can  represent an array of records. These are effectively multidemensional arrays.
As for classes, I wouldn't think it necessary to represent a record as such as in the serial or a sequential file example in the Fitzpatrick book in the quote from Laurie. 
Interestingly the syntax for a class is :

   <?php 
            class student {
                var $fname = "john";
                var $surname = "smith";
                var $age = "17";
           }
     $myStudent = new student();
     echo "Student details".$myStudent->fname." " .$myStudent-> surname."  " .$myStudent->age;
?>
   
  It does look and feel like a record.  It is the class definition and instantiation that might throw the students I am thinking. 

Keep well

I am not sure of what the text says ( I use the other book :) but records per se are not basic data types.
In PHP you can use a CSV file to store records and then process these using a simple array where the array position is a "field" and every element is initially a string.

This is my first time teaching SD. We’re using PHP and the Fitzpatrick/Keane text. PHP doesn’t have a specific type called a “record” and a single vector array doesn’t seem to match the concept as illustrated (fig 6.5, page 162). Looking at the example in the text I’m wondering if I could describe it as an instance of a class?
