Learning OOP

[deansatch]

I have been using php for a long time now and I am know it very well. I feel it is time I learned OOP though. I have been reading up on it and if I understand correctly, it allows total separation of html and php backend stuff.

 

I am however having trouble finding examples or tutorials that show OOP in a real world useful way.

 

e.g.

 

I have a simple while loop output in to a table which I currently do like this:

 

$v_list ="<h2>Variable List</h2>\n
<div><table><thead><tr><td>V 1</td><td>V 2</td><td>V 3</td></tr></thead><tbody>\n";
$query = mysql_query("SELECT * from table");
$vnum=0;
$vnum = mysql_num_rows($query);
while($row = mysql_fetch_assoc($query)){;
$v1= $row['v1'];
$v2= $row['v2'];
$v3= $row['v3'];

$v_list .= "<tr><td>$v1</td><td>$v2</td><td>$v3</td></tr>\n";

}
$v_list .= "</tbody></table></div>";
if($vnum> 0){echo $v_list;}

 

How could I use OOP to keep the php part in a separate file from the html?

 

e.g.

 

file 1:

my php code looping and setting of variables

 

file 2:

<h2>Variable List</h2>

<div>
<table>
<thead>
<tr><td>V 1</td><td>V 2</td><td>V 3</td></tr></thead><tbody>
<tr><td>$v1[0]</td><td>$v2[0]</td><td>$v3[0]</td></tr>
<tr><td>$v1[1]</td><td>$v2[1]</td><td>$v3[1]</td></tr>
<tr><td>$v1[2]</td><td>$v2[2]</td><td>$v3[2]</td></tr>
</tbody>
</table>
</div>

 

Thanks in advance

it allows total separation of html and php backend stuff.

 

While OOP can assist in this area, its far from its main objective, so I think you may have been given a bum steer there.

 

If you want to learn OOP, I would suggest picking up one of the bigger frameworks and building a few projects with it. These usually impliment a few different design patterns including MVC.

 

Zend Framework is pretty darn popular atm.
