just to clarify: the data is 1 line at a time, or are the 3 information in 1 line each time? in the latter case, what is the separator?

now: EE is not a rent-a-coder, so you should try to clarify/check out the different parts of such a "simple" problem yourself:
* read a file
* split a string into parts (not necessarily required here...)
* write a sql statement for the INSERT
* run the sql statement

so, read up the sites php.net and mysql.com to get basic samples, and come back with concrete problems you have then, posting the code you have then, and the errors/problems you run into.

one line as a separator between firstname, lastname and email address

two lines as a separator between block of firstname lastname and email address

Read the file with fopen & fread (read in php.net)

after that explode the string with \n (new line seperator)

do foreach to work over the array and insert into the database with mysql query

example included...
$filename = "/usr/local/something.txt";
$handle = fopen($filename, "r");
$contents = fread($handle, filesize($filename));
fclose($handle);
 
$content_array = explode("\n", $contents);
 
foreach ($content_array AS $name => $value) {
mysql_query("INSERT INTO table SET field = '$value'");
}

Something like this should get you started. I'll have to verify the field names of your database table.


$link = mysql_connect("localhost", "mysql_user", "mysql_password") 
       or die("Could not connect: " . mysql_error()); 
 
$handle = fopen ("/tmp/inputfile.txt", "r"); 
while (!feof ($handle)) { 
   $first_name = mysql_real_escape_string(fgets($handle)); 
   $last_name =  mysql_real_escape_string(fgets($handle)); 
   $email =      mysql_real_escape_string(fgets($handle)); 
   
   $sql_command="insert into customers (first_name, last_name, email ) values ('$first_name', '$last_name', '$email')";
   $ok=mysql_query($sql_command);
} 
fclose ($handle);

try this ... change the variable of course

<?php
//reading file
$filename = "firstnamelastnameemail.txt";
$file = file($filename);
 
//database settings
$db = "test";
$table = "users";
$col1 = "first";
$col2 = "last";
$col3 = "mail";
 
//connect to mysql
$connection = mysql_connect('localhost', 'root', 'root') or die (mysql_error());
$db = mysql_select_db('test', $connection) or die (mysql_error());
 
//do the reading loop
$j = 0;
$result = array();
for ($i=0;$i< count($file);$i++) {
if ($j == 3)
{
//do the sql query
$query  = "insert into $table (`$col1` , `$col2` , `$col3` ) values ('$result[0]', '$result[1]', '$result[2]')";
$res = mysql_query($query) or die('Error, query `' . $query . '` failed');
$j = 0;
}
if ($file[$i] != "\n") {
$result[$j] = $file[$i];
$j++;
}
        }
 
        mysql_close($connection);
 
 
?>

I would do something like this:
mysql_connect('localhost','user','pass') or die('Could not connect: '.mysql_error());
mysql_select_db('dbname') or die("Could not select database '$dbname'");
$data = file_get_contents('firstnamelastnameemail.txt');
$records = explode("\n\n\n",$data);
$inserted = 0;
foreach($records as $record) {
  list($fname,$lname,$email) = explode("\n\n",$record); 
  $fname = mysql_real_escape_string($fname);
  $lname = mysql_real_escape_string($lname);
  $email = mysql_real_escape_string($email);
  $res = mysql_query("insert into MyTable set fname='$fname',lname='$lname',email='$email'");
  if(!$res) echo 'Failed: '.$fname.' '.$lname.' '$email.'<br />'.mysql_error().'<br />';
  else $inserted++;
}
echo $inserted.' rows inserted.';

Sorry, error in line 12, a missing dot, it should be:

if(!$res) echo 'Failed: '.$fname.' '.$lname.' '.$email.'<br />'.mysql_error().'<br />';

you could just add a few read lines to my code

$first_name = mysql_real_escape_string(fgets($handle)); 
$blank=fgets($handle);
$last_name =  mysql_real_escape_string(fgets($handle)); 
$blank=fgets($handle);
$email =      mysql_real_escape_string(fgets($handle)); 
$blank=fgets($handle);
$blank=fgets($handle);
