Make a txt file display in reverse

gallienne09 · 10-26-2009, 10:43 PM

Can some one tell me how to reverse the text file so it displays what goes in last first.

Cheers in advance

here is the code:

<html>
<head>
<title>test Text</title>
</head>
<body>
<div style='overflow:auto; width:230px; height:500px; background-color:orange'>
<fieldset width="200">
<legend>
<b>Message Board:</b>
</legend>

<form method="POST" action="text.php" style="font-family:verdana; font-size:10pt">
Nickname:<br><input type="text" name="name" size="25"/><br>
Comment:<br><textarea name="comment" rows="4" cols="23">
</textarea><br>
<input type="submit" value="Submit" />
<input type="reset" value="Reset" />
</form>
</fieldset>

<?php
$date= date("d/m/y");
$name=$_POST['name'];
$comment=$_POST['comment'];

if ($comment != "" )
{
$myFile = "testFile.txt";
$fh = fopen($myFile, 'a') or die("can't open file");
$stringData = "<b>Posted: $date</b>\n<br>";
fwrite($fh, "$stringData");
$stringData = "\"$comment\"\n<br>";
fwrite($fh, "$stringData");
$stringData = "<b>By:$name</b>\n<hr>";
fwrite($fh, $stringData);
fclose($fh);
}

else
{
echo "<b style='color:red'>Please fill in all fields!</b>";
}
?>

<?php

$myFile = "testFile.txt";
$fh = fopen($myFile, 'r');
$theData = fread($fh, filesize($myFile));
fclose($fh);

echo "
<table border='0' width='210' align='center'>
<tr>
<td style='font-family:verdana; font-size:8pt'>
$theData
</td>
</tr>
</table>

";
?>
<?php

?>
</div>
</body>
</html>

php Code:

$arr = file( YOUR_FILE );
$arr = array_reverse( $arr );

That takes all the fun out of learning. :)

php Code:

$myFile = "testFile.txt";
$fh = fopen($myFile, 'r');
$theData = fread($fh, filesize($myFile));
fclose($fh);

Would be...

php Code:

$myFile = 'testFile.txt';
$theData = array_reverse( file( $myFile ) );

foreach ( $theData as $row )
    echo $row . '<br />';

Or however you wish. There's about 3,141.59265 ways to do anything in PHP.
