[Resolved] array_reverse() question!

[Spud_Nic]

Hi, I'm quite new to php... never used array reverse before and can't get it to work!!!!

What I want to do, is output contents of a text file backwards - i.e. most recent first. i've but the code i'm using below... but how do I add array_reverse into it?

everything I've tried hasnt worked! Thanks.

function ReadFromFile() {

$TheFile = "guestbookdata.txt";
$Open = fopen ($TheFile, "r");

if ($Open) {
	$Data = file ($TheFile);
	for ($n=0; $n < count($Data); $n++) {
		$GetLine = explode("\t", $Data[$n]);
		print ("<table border=\"1\" bordercolor=\"black\" cellspacing=\"0\" cellpadding=\"4\" align=\"center\" width=\"400\">\n");
		print ("<tr>\n");
			print ("<td align=\"center\" width=\"10%\" rowspan=\"2\" valign=\"top\">ONE</td>\n");
			print ("<td align=\"left\" width=\"*\">Posted by $GetLine[0] on $GetLine[3] <br><span style=\"font-size:8pt;\">$GetLine[1]</span> - <span style=\"font-size:8pt;\">$GetLine[4]</span></td>\n");
			print ("<td align=\"center\" width=\"10%\" rowspan=\"2\" valign=\"top\">DEL</td>\n");
		print ("</tr>\n");
		print ("<tr>\n");			
			print ("<td align=\"left\" width=\"*\">$GetLine[2]</td>\n");
		print ("</tr>\n");
		print ("</table><br>\n");
	}
fclose ($Open);

} else {
	print ("<font color=red><b>Unable to load Guestbook. Please try again later.</b></font><br>\n");
}

}

function ReadFromFile() { 

$TheFile = "guestbookdata.txt"; 
$Data = @file ($TheFile); 
if( $Data !== FALSE )
{
$Data = array_reverse( $Data );

for ($n=0; $n < count($Data); $n++) { 
$GetLine = explode("\t", $Data[$n]); 
print ("<table border=\"1\" bordercolor=\"black\" cellspacing=\"0\" cellpadding=\"4\" align=\"center\" width=\"400\">\n");
