PHP Guestbook sorting

[alen]

I made this simple guestbook script which stores everything in a file. I would have used a sql database, but I don't have one. Anyway .. I need to sort the entries. The newest entry comes first.

 

You can find my script at;

http://anigma.sitees.com/Guestbook/lagre.phps (lagre=save)

 

and you can test my script here;

Any idea on what I can do? I know how to sort it with MySQL, but I think it's not quite the same.

You can read all the entires in array with keys of the array set to the date of each entry. You can then sort the array.

Could you show me an example? Thanks!

 

I'm new to this

I posted this yesterday, may be of use to you.

 

<?php
function setSortVar(&$item, $key, $sortBy)
	{
	$item[0]=$item[$sortBy];
	}

function myArraySort($x, $y)
	{
	if ($x[0] == $y[0])
		{
		return 0;
		}
	else if ($x[0] < $y[0])
		{
		return -1;
		}
	return 1;
	}

$myCollection = array();
$myCollection[0][0]=""; // Sorting Value
$myCollection[0][1]="Die Die Die"; // Name
$myCollection[0][2]="Movie"; // Main Category
$myCollection[0][3]="DVD"; // Sub Category
$myCollection[0][4]="Drama"; // Type of movie

$myCollection[1][0]=""; // Sorting Value
$myCollection[1][1]="Worm Race"; // Name
$myCollection[1][2]="Movie"; // Main Category
$myCollection[1][3]="DVD"; // Sub Category
$myCollection[1][4]="Action"; // Type of movie

$myCollection[2][0]=""; // Sorting Value
$myCollection[2][1]="Ha ha."; // Name
$myCollection[2][2]="Movie"; // Main Category
$myCollection[2][3]="HDDVD"; // Sub Category
$myCollection[2][4]="Comedy"; // Type of movie

$sortBy=1;

//Look for sort vars
if (isset($_GET['sortBy']))
	{
	switch ($_GET['sortBy'])
		{
		case 1:
		$sortBy=1;
		break;
		case 2:
		$sortBy=2;
		break;
		case 3:
		$sortBy=3;
		break;
		case 4:
		$sortBy=4;
		break;
		default:
		$sortBy=1;
		break;
		}
	}

array_walk($myCollection, 'setSortVar', $sortBy);
usort($myCollection, 'myArraySort');
print_r($myCollection);
?>

1- use file("filepath"); function to read all the entries line by line in an array.

2- now you can loop through all the elements of the array and parse each array element.

3- find out date in the array element.

4- craeate another array and put date as key of the array element and rest of the data as value.

5- use ksort(), krsort() array functions to sort the array.

 

Hope this will help
