Flat File Question

[voyde]

Ok I need a flat file to hold one variable... ten different times.

 

A user submits let say their name, the script adds the users name into the flat file erasing the one at the bottom (so there is only 10 at a time).

 

What i got...

	
$filename = $configpath.'lastten.txt';
if (!$handle = fopen($filename, 'r+')) {
         $error = "Cannot open file ($filename)";
         exit;
    }
    if (fwrite($handle, $direct_link) === FALSE) {
        $error = "Cannot write to file ($filename)";
        exit;
    }
    fclose($handle);

 

How on earth do i get it to write the latest at the top and remove the what once was number 10.

Are you using PHP4 or 5?

 

It would probably be easier to read in the original ten lines, store that as an array, edit the last index and then overwrite the original file with a new one. Would need to know what version your using though.

Php 5

Try something like this,

 

<?php

$filename = $configpath.'lastten.txt';

// Read in file
if ($details = file($filename)===false) {
$error = "Cannot open file {$filename}";
exit;
} else

// Change last index
$details[9] = "My new string\n";


if ($result = file_put_contents($filename,$details)===false) {
   $error = "Cannot write to file ($filename)";
   exit;
}

?>

 

I am not at a server to test this but using these two functions better then using the fopen methods.

That doesnt work it just keeps making one line with the most recent data.

works for me:

 

<?php

$filename = $configpath.'lastten.txt';

// Read in file
$details = file($filename);

// Change last index
$details[9] = "My new string\n";

if ($result = file_put_contents($filename,$details)===false) {
   $error = "Cannot write to file ($filename)";
   exit;
}

?>
