[Year 12 SofDev] Records in PHP

[Laurie Savage]

I was playing with an idea along the lines of

class Student{
	public $name;
	public $age;
	public $class;

	public function writeStudent(){
		$fileName = $this-> name.".csv";
		$fh = fopen($fileName, a+);
		$contents = "$this->name, $this->age, $this->class";
		fwrite($fh, $contents);
	}
}

$johnny = new Student;
$johnny->name = "Johnny";
$johnny->age = 12;
$johnny->class = "6A";
$johny->writeStudent();

$liza = new Student etc

which creates a data file for each student.

> 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?
