Order a multiple line variable

[jonybhi]

Hello,

I've a text file containing data for images its like:

 

1:thumb_1.gif:large_1.gif

8:thumb_2.gif:large_2.gif

5:thumb_3.gif:large_3.gif

 

Array 0 represent views, Array 1 represents thumbnail and Array 2 represents full size image.

 

I'm using the following code to display images:

 

<?php


$file_handle = fopen("datafile.txt", "rb");
while (!feof($file_handle) ) 
{	
	$line_of_text = fgets($file_handle);
	$parts = explode('/n', $line_of_text);
	foreach($parts as $gallery_data)
	{

		$data = preg_split('/:/', $gallery_data);	
	?>

<img src="<?php echo $data[0]; ?>" width="150" height="150">

	<?php


	}
}
fclose($file_handle);

?>

 

the above code displays the images in text file order. I'd like it to display most viewd image first, for which the data in variable $line_of_text should be:

 

8:thumb_2.gif:large_2.gif

5:thumb_3.gif:large_3.gif

1:thumb_1.gif:large_1.gif

 

so the question is, how can i arrange it?

Should be easier (not tested):

 

foreach(file('datafile.txt') as $key => $value) {
   $data[$key] = explode(':', $value);
   $view[$key] = $data[$key][0];
}
array_multisort($view, SORT_DESC, $data);
