如何找出所有产品中的缺失图片？

昨天突然发现公司受理的一个网站有些图片不显示。初步认为是图片地址失效或者本地图片库图片缺失，于是写了个检查的小程序，写下来，面得忘记了。

<?php

/*
* To change this template, choose Tools | Templates
* and open the template in the editor.
*/
require('includes/application_top.php');
$res = tep_db_query("select * from " . TABLE_PRODUCTS . " p, " . TABLE_PRODUCTS_DESCRIPTION . " pd where p.products_status = '1' and pd.products_id = p.products_id and pd.language_id = '" . (int) $languages_id . "'");
while ($product_info = tep_db_fetch_array($res)) {
if (!empty($product_info['products_description'])) {
if (preg_match('/<img.*?(?: |\\t|\\r|\\n)?src=[\'"]?(.+?)[\'"]?(?:(?: |\\t|\\r|\\n)+.*?)?>/sim', $product_info['products_description'])) {

echo '<span style="color:red;">' . $product_info['products_model'] . '</span>';
echo '########## id:' . $product_info['products_id'];
echo '----------------link:<a href="' . tep_href_link(FILENAME_PRODUCT_INFO, 'products_id=' . $product_info['products_id']) . '">' . tep_href_link(FILENAME_PRODUCT_INFO, 'products_id=' . $product_info['products_id']) . '</a>';
echo '<br>';

preg_match_all('/<img.*?(?: |\\t|\\r|\\n)?src=[\'"]?(.+?)[\'"]?(?:(?: |\\t|\\r|\\n)+.*?)?>/sim', $product_info['products_description'], $outinfo);
foreach ($outinfo[1] as $key => $out) {
echo $out . '<br>';
$hostnameby = substr($out, 0, 23);
$hostnamebywww = substr($out, 0, 27);

if ($hostnamebywww === 'http://xxx.xom/') {
$imgurl = substr($out, 27);
}else if ($hostnameby === 'http://www.xxx.xom/') {
$imgurl = substr($out, 23);
}else{
echo 'this is old<br>';
echo '<img src="'.$out.'" width="200" height="200"/><br>';
}
define('PC_PATH', dirname(__FILE__));
define('DS', DIRECTORY_SEPARATOR);
if (!file_exists(PC_PATH . DS . $imgurl)) {
echo '<img src="'.HTTP_SERVER . '/' . $imgurl . '" width="200" height="200"/><br>';
echo $imgurl.'<br>';
}
unset($imgurl);
}
echo '<br><br>';
}
}
}

require(DIR_WS_INCLUDES . 'application_bottom.php');
?>

首先用sql语句查找所要检查的产品

因为图片存在于产品描述中，我们只对有产品描述的产品进行查找

if (!empty($product_info['products_description'])) {}

产品描述中要有图片才可能出现不显示的情况，所以

if (preg_match('/<img.*?(?: |\\t|\\r|\\n)?src=[\'"]?(.+?)[\'"]?(?:(?: |\\t|\\r|\\n)+.*?)?>/sim', $product_info['products_description'])) {}

正则表达式是我无耻的从网上拿来用的，鄙视一下。

之后输出一些关键信息查看

再用preg_match_all() 函数检查所以图片

foreach() 循环检查

输出没有的图片

if (!file_exists(PC_PATH . DS . $imgurl)) {
echo '<img src="'.HTTP_SERVER . '/' . $imgurl . '" width="200" height="200"/><br>';
echo $imgurl.'<br>';
}

如果是外连图片就直接输出

}else{
echo 'this is old<br>';
echo '<img src="'.$out.'" width="200" height="200"/><br>';
}

最后运行看输出的结果

唉，最后还得人工检查，真失败。如果能写成自动的就好了，目前没想到方法。

附：后来要求找出已经恢复的产品相的产品号

修改了下上面的程序，终于不用手工了

while ($product_info = tep_db_fetch_array($res)) {

//print_r($outinfo);
foreach ($outinfo[1] as $key => $out) {

$hostnameby = substr($out, 0, 31);

if ($hostnamebywww === 'http://www.xxx.xxx/picture/') {
$imgurl = substr($out, 35);

} else if ($hostnameby === 'http://xxx.xxx/picture/') {
$imgurl = substr($out, 31);

} else {
$imgurl = '';
}
if ($imgurl != '') {
echo '<img src="' . HTTP_SERVER . '/picture/' . $imgurl . '" width="200" height="200"/><br>';
echo $imgurl . '<br>';

$content.=$product_info['products_model'];
$content.="," . $link;
$content.="," . HTTP_SERVER . '/picture/' . $imgurl;
//$content.=",";
$content = $content . "\r\n";
}
unset($imgurl);
}
echo '<br><br>';
}
}
}
$fp = fopen("imginfo.csv", 'w');
fwrite($fp, $content);
fclose($fp);
