PHP无用图片清理,php – 如何在img / p /上删除Prestashop无用的图像
在Prestashop,當(dāng)我刪除一些產(chǎn)品時(shí),圖像保留在他們的目錄/ img / p / so,此時(shí)我的圖像目錄接近2GB.
找到這個(gè)腳本來(lái)刪除Prestashop上無(wú)用的和BBDD未鏈接的圖像,但我不知道為什么它只檢測(cè)孤立圖像但不刪除它們.也許在php配置上禁用unlink功能？可能嗎？或者代碼錯(cuò)了？還有另一種方法可以進(jìn)行這種清理嗎？
// root path of the shop
$shop_root='/home/myweb/public_html/';
// limit number of image files to check, set to 10 for testing
$limit=1000000000;
include $shop_root . '/config/settings.inc.php';
$pdo = new PDO( 'mysql:host='._DB_SERVER_.';dbname='._DB_NAME_, _DB_USER_, _DB_PASSWD_ );
$pdo->setAttribute(PDO::ATTR_ERRMODE, PDO::ERRMODE_EXCEPTION);
$r=$pdo->query('select count(1) cnt from ps_image')->fetch();
echo 'count images database: '.$r['cnt'] . "
";
// reset some counters
$cnt_files=0;
$cnt_checked=0;
$cnt_not_found=0;
$cnt_found=0;
for($ii=1; ($ii<=9) && ($cnt_files != $limit); $ii++)
{
$path=$shop_root.'img/p/'.$ii;
delImage($path);
for($jj=0; ($jj<=9) && ($cnt_files != $limit); $jj++)
{
$path=$shop_root.'img/p/'.$ii.'/'.$jj;
delImage($path);
for($kk=0; ($kk<=9) && ($cnt_files != $limit); $kk++)
{
$path=$shop_root.'img/p/'.$ii.'/'.$jj.'/'.$kk;
delImage($path);
for($ll=0; ($ll<=9) && ($cnt_files != $limit); $ll++)
{
$path=$shop_root.'img/p/'.$ii.'/'.$jj.'/'.$kk.'/'.$ll;
delImage($path);
}
}
}
}
echo 'files: '.$cnt_files.' checked: '.$cnt_checked.' not_found: '.$cnt_not_found.' found: '.$cnt_found;
function delImage($imageDir)
{
global $limit, $pdo, $cnt_files, $cnt_checked, $cnt_not_found, $cnt_found;
if ($handle = @opendir($imageDir)) { //@ is wriiten to avoid warning message and is handled in else condition
echo $imageDir."
";
while ($cnt_files != $limit && false !== ($entry = readdir($handle))) {
if ($entry != "." && $entry != "..") {
$cnt_files++;
$pi = explode('-',$entry);
if($pi[0]>0 && !empty($pi[1])) {
$cnt_checked++;
if(!checkExistsDb($pdo,$pi[0])) {
$cnt_not_found++;
echo 'rm '.$imageDir.'/'.$entry."
";
unlink($imageDir.'/'.$entry);
} else {
$cnt_found++;
}
}
}
}
closedir($handle);
}
else
{
echo $imageDir." doesn't exist".'
';
}
}
function checkExistsDb($pdo, $id_image) {
$r=$pdo->query($q='select \'ok\' ok, (select id_image from ps_image where id_image = '.(int)$id_image.') id_image');
$row=$r->fetch();
if($row['ok']!='ok') die( 'Problem with query, please correct');
return $row['id_image']?true:false;
}
?>
