It's not the most elegant way, but it works:

<?php
function sqlite_field_names($db, $tablename){
    $sq5=sqlite_single_query($db, "SELECT sql FROM sqlite_master WHERE tbl_name='".$tablename."'", SQLITE_NUM);
    $kommando=$sq5[0];
    $cut=strtok($kommando,"(");
    while($fieldnames[]=strtok(",")) {};
    array_pop($fieldnames);
    foreach($fieldnames as $no => $field)
        if (strpos($field, "PRIMARY KEY")){
            strtok($field,"(");
            $primary=strtok(")");
            unset($fieldnames[$no]);
        } else
            $fieldnames[$no]=strtok($field, " ");
    return $fieldnames;
}
?>

While working with SQLite using its object-oriented mode, I found need to display a column/field name without knowing what it was in advance.  I couldn't find any examples on the Internet, just this document.  So, for anyone who happens to need to do this, here's an example.

<?php

$db = "db/database.sqlite";

// create new database (OO interface)
$dbo = new SQLiteDatabase("$db");

// create table foo and insert sample data
$dbo->query("
 CREATE TABLE foo(id INTEGER PRIMARY KEY, name CHAR(255));
 INSERT INTO foo (name) VALUES('Ilia1');
 INSERT INTO foo (name) VALUES('Ilia2');
 INSERT INTO foo (name) VALUES('Ilia3');
");

$query = "SELECT * FROM foo;";

$result = $dbo->query($query) or die("Error in query");

echo "
<table border='1' cellpadding='10'>
 <tr>
  <td>".$result->fieldName(0)."</td>
  <td>".$result->fieldName(1)."</td>
 </tr>";

// iterate through the retrieved rows
while ($result->valid()) {
  // fetch current row
  $row = $result->current();
  echo "
 <tr>
  <td>".$row[0]."</td>
  <td>".$row[1]."</td>
 </tr>";
  // proceed to next row
  $result->next();
}

echo "</table>";

?>

This code works with SQlite version 3 databases. 
<?php
function sqlite_field_names($dbfile, $tablename){
    try
      {
    $db = new PDO("sqlite:".$dbfile);
    $sql=$db->query("SELECT sql FROM sqlite_master WHERE tbl_name='".$tablename."'");
    foreach($sql as $row)
        {
        $fields = $row["sql"];
        }
    $db = NULL;
   }
   catch(PDOException $e)
   {
    print "Exception : ".$e->getMessage();
   }
    $cut=strtok($fields,"(");
    while($fieldnames[]=strtok(",")) {};
    array_pop($fieldnames);
    foreach($fieldnames as $no => $field)
        if (strpos($field, "PRIMARY KEY")){
            strtok($field,"(");
            $primary=strtok(")");
            unset($fieldnames[$no]);
        } else
            $fieldnames[$no]=strtok($field, " ");
    return $fieldnames;
}

print_r(array_values(sqlite_field_names($dbfile, $tablename)));
?>
