Extracting info from a text file

Recommended Posts

Hi there,

I'm setting up an online portfolio and would like to know what the best way to pull up image descriptions would be. I've seen it done before by setting up a text file like this:

image1.jpg; information about this one
image2.jpg; information about the second one.

then when you load image1.jpg onto the page, you also pull up "information about this one" into the page.

Right now I just have a navigation set up where the link is to index.php?id=imagename

and then I load the appropriate image like so:

[code]$first = array('home','about','contact', 'work');

if (in_array($_GET['id'], $first)) {
          print '<img src="http://' . $_SERVER['HTTP_HOST'] . '/images/' . $_GET['id'] . '.jpg" alt="title" />';[/code]

I'm not even sure what the process would be called so I haven't really been able to do research on it.

I know I could set up something using line numbers and call the images by numbers that calls up the appropriate line number - but I'd prefer to have it know which line to pull based on the variable $id.

You can use explode() 2 times... But I would rather create a multidimensional array:

[code]
$data = array (
   '0' => array (
      'img'   => 'image1.jpg';
      'descr' => 'information about this one'
    ),

   '1' => array (
      'img'   => 'image2.jpg';
      'descr' => 'information about the second one.'
    ),
);[/code]

serialize() it and store in a txt. It's more accurate.

I am pretty new at php so I think I need a little bit more information - can anyone either direct me to a tutorial or a script that I could customize?
