由 dawei 使用文本数据库一般是针对小型的应用程序了,这种不就需要安装数据库了,我们可以直接操作文本文件就可以了,但时怎么操作都不如mysql数据库好用了,下面我来给大家介绍一个文本数据库转为mysql数据库实例,代码如下:
<?php
require_once 'config.php';
$action = emptyempty($_GET['action']) ? '' : $_GET['action'];
$id = isset($_GET['id']) ? $_GET['id'] : 0;
if (emptyempty($action)) {//列表
$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));//数据条目总数
$pageall = ceil($total/$items);
$offset = ($page-1)*$items;//数据开始位置
$result .= " limit {$offset},{$items}";//每页显示
$results = mysql_query($result);
$prev = $page - 1;
$next = $page + 1;
$goPrev = "<a href="?page=$prev">上一页</a>";
$goNext = "<a href="?page=$next">下一页</a>";
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 != $page) ? "<a href="?page=$i">$i</a>" : $i;
$pagelinks .= ($i < $pageall) ? '-' : null;
}
// end 分页
$data = array();
//列出文章
while ($row = mysql_fetch_array($results)) {//mysql_fetch_array ; 从查询结果取出一行作为数组；
$data[] = $row;//
}
//列出分类
$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') {//发表
$title = $_POST['title'];
$date = date("Y-m-d H:i:s");
$content = $_POST['content'];
$cid = $_POST['cat'];
if ($title == '' || $content == '' || $cid == '') {
echo "缺少必填项nnnn<a href="javascript：history.go(-1);">返回</a>";
} 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; }
$insertRview = "INSERT INTO review (pid,name,review) VALUES ('$id','$name','$review')";
if (!mysql_query($insertRview,$sql)) {
die('ERROR: ' . mysql_error());
}
header("location: ?action=view&id=$id");
}
$rert = mysql_query("SELECT * FROM review WHERE pid='$id' ORDER BY rid ASC");
$data = array();
while ($relist = mysql_fetch_array($rert)){
$data[] = $relist;
}
include template('view');
} elseif ($action == 'del') {//删除
mysql_query("DELETE FROM posts WHERE pid='$id'");

header("location: index.php");
} else {
$row = mysql_query("SELECT * FROM posts WHERE pid='$id'");
$row = mysql_fetch_array($row);
include template('edit');
}
} elseif ($action == 'newcat') {//新建分类
$cat = isset($_POST['category']) ? $_POST['category'] : 0;
if ($_SERVER['REQUEST_METHOD'] == 'POST') {
if ($cat == '') { echo "缺少必填项nnnn<a href="javascript：history.go(-1);">返回</a>"; exit;}
$insertCat = "INSERT INTO category (category) VALUES ('$cat')";
if (!mysql_query($insertCat,$sql)){

$pagestate .= $goPrev;

}
$pagelinks = '';

$pagelinks .= ($i != $page) ? "<a href="?action=vcat&cid=$cid&page=$i">$i</a>" : $i;
$pagelinks .= ($i < $pageall) ? '-' : null;
} //开源代码Cuoxin.com
$data = array();
while ($vclist = mysql_fetch_array($revcat)) {
$data[] = $vclist;
}
include template('cplist');
}
mysql_close($sql);
题外话了,一个access转换成mysql数据库的实例.
