PHP 、shell、crontab 执行定时任务

为了实现自动更新网站数据的功能，使用PHP 、shell、crontab 执行定时下载文件、读取文件并更新数据库。

一、思路

1、linux编写shell使用wget下载链接文件。

2、php读取下载的文件并存储数据到数据库。

3、使用linux crontab定时任务执行1、2步骤即可。

代码如下：

1、shell代码

#!/bin/sh
if 
#wget 下载文件并把文件按照日期重命名
wget -c http://www.****.cn/***/***C?type=productType -O /home/***/$(date -d "today" +"%Y%m%d")productType.txt -o /***/wget.log 
wget -c http://www.****.cn/***/***C?type=product -O /home/***/$(date -d "today" +"%Y%m%d")product.txt -o /***/wget.log
#把下载好的文件复制到PHP项目中
cp /***/$(date -d "today" +"%Y%m%d")productType.txt /***/w***/default/****/upload/$(date -d "today" +"%Y%m%d")productType.txt
cp /***/$(date -d "today" +"%Y%m%d")product.txt /***/upload/$(date -d "today" +"%Y%m%d")product.txt
then 
echo "数据下载成功！">>/***/access.log;
date +%Y%m%d%H%I%S>>/***/access.log
else
echo "数据下载失败！">>/***/error.log;
date +%Y%m%d%H%I%S>>/***/error.log
fi

2、PHP代码

<?php

 * Time: 15:59
 */

$handler = mysql_connect("localhost", "root", "****");
mysql_select_db("****_products");
mysql_query("SET AUTOCOMMIT=0");//设置为不自动提交，因为MYSQL默认立即执行
mysql_query("BEGIN");//开始事务
if (empty($dopost)) $dopost = "";
$file = "upload/".date("Ymd",time()).'productType.txt';
$get = fopen($file, 'r');//mysql读取文件
if ($get) {
    $del = "DELETE FROM `#@__products_type`";
    $js = $dsql->ExecuteNoneQuery($del);
    while (!feof($get)) {
        $oneline = fgets($get);
        $contents = explode("ξδθ", $oneline);
        $id = $contents[0];
        $name = $contents[1];
        $er = $contents[2];
        $err = $contents[3];
        if ($name == null || $err != null) {
            echo "本条数据格式不正确，上传失败" . '<br/>';
        } else {
            echo $id . "|" . $name . '<br/>';
            $inquery = "INSERT INTO `#@__products_type`(id,name) VALUES ('$id','$name')";
            $dsql->ExecuteNoneQuery($inquery);
        }
    }
} else {
    echo "更新产品类型失败！请使用“上传产品资料”功能更新数据！" . '</br>';
    die;
}
$file = "upload/".date("Ymd",time()).'product.txt';
$fh = fopen($file, 'r');
if ($fh) {
    echo "内容为:" . '<br/>';
    while (!feof($fh)) {
        $oneline = fgets($fh);
        $contents = explode("ξδθ", $oneline);

        if ($deleted == null || $err != null) {
            echo "本条数据格式不正确，上传失败" . '<br/>';
        } else {

            $row = $dsql->GetOne("SELECT id FROM `#@__products` WHERE ReportNo = '$ReportNo'");
            $shuzu = $row['id'];
            echo $id . "|" . $progress . "|" . $testDepartmentID . "|" . $ProductName . "|" . $ProductModel . "|" . $ProductType . "|" . $ProductTypeName . "|" . $SendCompany .

            if (!empty($shuzu)) {
                $update = "update `#@__products` SET id='$id',progress='$progress',
        testDepartmentID='$testDepartmentID',
        ProductTypeName = '$ProductTypeName',
        ProductName = '$ProductName',
        ProductModel = '$ProductModel',

fclose($get);
fclose($fh);

3、定时任务

每周五上午10点更新数据  *(分)  *(时)  *(日)  *(月)  *(周)
[root@localhost]# crontab  -l
00 10 * * 5 /home/****/***g.sh      
05 10 * * 5 /usr/bin/curl http://www.****.net/****/***.php

经过测试更新成功！
