PHP无用图片清理,php – 如何在img / p /上删除Prestashop无用的图像

在Prestashop,当我删除一些产品时,图像保留在他们的目录/ img / p / so,此时我的图像目录接近2GB.

找到这个脚本来删除Prestashop上无用的和BBDD未链接的图像,但我不知道为什么它只检测孤立图像但不删除它们.也许在php配置上禁用unlink功能？可能吗？或者代码错了？还有另一种方法可以进行这种清理吗？

// 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;

}

?>

这是一个输出部分：
