在sqlite中插入太多数据

I keep inserting data into the table t1 by keeping to refresh the browser. After inserting around 30 records, returns me with an error 103.

<?php

function string($s, $quote = FALSE) 
{
    if ($s === NULL) return 'NULL';
    $r = sqlite_escape_string($s);
    if ($quote) return "'".$r."'";
    return $r;
}
if ($db = sqlite_open('fs.db', 0666, $sqliteerror)) 
{ 
    $sqlCreate = "create table t1   (id char(13) NOT NULL,path char(255) NOT NULL,PRIMARY KEY (id))";
    $id = uniqid("");
    $p = "hellovimal";
    $prevsql = sprintf("INSERT INTO t1 (id, path) VALUES (%s,%s)",string($id, TRUE), string($p, TRUE));
    $result = sqlite_query( $prevsql,$db, SQLITE_NUM, $err);

} 
else 
{
    die($sqliteerror);
}

Here is the screenshot

Why such an error occur after inserting around 35 records and how i can fix it ?
