How to delete lines from a txt file based on checkbox selection

[anzacdan]

Hey all need some help with the subject title.

 

Have a user text file with all information(Name, address, passwords, etc..) Need to be able to select the user based on Checkbox selection then hit delete button and all users checked will be removed from the txt file and thus removed from HTML page. Im using PHP to show contents of the txt file into my HTML page.

 

So far i have:

 

 

<?php

$file = fopen("user.txt","r");

 

echo '<table border="0" width="100%">

<tr>

<th>Select</th>

<th>Username</th>

<th>Password</th>

<th>FirstName</th>

<th>LastName</th>

<th>Email</th>

<th>Address</th>

</tr>

';

while(!feof($file)) {

$user = explode(":", fgets($file));

 

echo '<tr>

<td><input type="checkbox" name="chkDelete" id = "chkDelete" value="select" /></td>

<td>' . $user[0] . '</td>

<td>' . $user[1] . '</td>

<td>' . $user[2] . '</td>

<td>' . $user[3] . '</td>

<td>' . $user[4] . '</td>

<td>' . $user[5] . '</td>

</tr>';

 

echo '</table>';

fclose($file);

?>

 

Am unsure as to how i would go about doing this, help would be greatly appreciated!

 

Thanks in advanced,

 

Daniel.

How are your users stored within your text file? I guess they are sperated by a :
