The use of text databases is generally for small applications. This does not require the installation of a database. We can directly operate text files, but no matter how we operate, it is not as easy to use as the mysql database. Let me explain below. Let me introduce an example of converting a text database into a mysql database.

The code is as follows

Copy code

require_once 'config.php';

$action = empty($_GET['action']) ? '' : $_GET['action'];
$id = isset($_GET['id']) ? $_GET['id'] : 0;

if (empty($action)) {//List

$result = "SELECT * FROM posts ORDER BY pid DESC";
$items = 3;
$page = isset($_GET['page']) ? intval($_GET['page']) : 1;
$page = ($page =='' && $page < 0) ? 1 : $page;
$total = mysql_num_rows(mysql_query($result));//Total number of data entries
$pageall = ceil($total/$items);
$offset = ($page-1)*$items;//Data starting position
$result .= "limit {$offset},{$items}";//Display on each page
$results = mysql_query($result);

$prev = $page - 1;
$next = $page + 1;
$goPrev = "Previous page";
$goNext = "Next page";

If ($page == $pageall){ $goNext = NULL;}

$pagestate = '';

If ($page == 1 && $pageall > 1) {
$pagestate .= $goNext;
} elseif ($pageall > $page || $page >1) {
$pagestate .= $goNext . '|' .$goPrev;
} elseif ($page >1 ) {
$pagestate .= $goPrev;
} else {
          $pagestate .= 'Just One Page';
}

$pagelinks = '';

for ($i = 1; $i <= $pageall; $i++) {
          $pagelinks .= ($i != $page) ? "$i" : $i;
          $pagelinks .= ($i < $pageall) ? '-' : null;
}

// end paging
$data = array();

//List articles
While ($row = mysql_fetch_array($results)) {//mysql_fetch_array; Take out a row from the query result as an array;
         $data[] = $row;//
}

//List categories
$recat = mysql_query("SELECT * FROM category ORDER BY cid DESC");
$cdata = array();

While ($catlist = mysql_fetch_array($recat)) {
          $cdata[$catlist['cid']] = $catlist;
}

Include template('index');

} elseif ($action == 'post') {//Publish

$title = $_POST['title'];
$date = date("Y-m-d H:i:s");
$content = $_POST['content'];
$cid = $_POST['cat'];

If ($title == '' || $content == '' || $cid == '') {

echo "Missing required fieldsnnnnReturn";

} else {

          $insertPost = "INSERT INTO posts (title, time, post, cid) VALUES ('$title','$date','$content','$cid')";

If (!mysql_query($insertPost,$sql)) {
            die('ERROR: '. mysql_error());
        }

        header('location: index.php');

    }

} elseif ($action == 'view') {//查看

    $view = mysql_query("SELECT * FROM posts WHERE pid='$id'");

    while ($row = mysql_fetch_array($view)) {

     $title    = $row['title'];
     $time     = $row['time'];
     $post     = $row['post'];

    }

    if ($_SERVER['REQUEST_METHOD'] == 'POST') {//评论

        $name   = isset($_POST['name']) ? $_POST['name'] : 0;
        $review = isset($_POST['review']) ? $_POST['review'] : 0;

        if ($name == '' && $review == '') { echo "缺少必填项";    exit; }
