i am working on a function to check an Array if there are special Chars i do not want to have.
The Main Function
public function scan()
{
$matches = array ();
foreach ($this->arr_select as $key => $value) {
if (preg_match_all(StringWorker::getRegex(), $value['filename'], $match)) {
$matches[$key]['id'] = $value['id'];
$matches[$key]['filename'] = $value['filename'];
$matches[$key]['chars'] = $match;
}
}
return $matches;
}
This is the Source Array
Array
(
[0] => Array
(
[id] => 2
[filename] => image_708_2_41_87026_gg_Mytrauringstore_Verlobungsringe_Saint_Maurice.jpg
)
...
[6861] => Array
(
[id] => 12322
[filename] => image_2623_йцу.JPG
)
...
[7162] => Array
(
[id] => 12699
[filename] => image_3050_Ringänderung_Service_kostenlos_Mytrauringstore.jpg
)
...
)
So with this Regex
protected static $regex = '([^a-zA-Z0-9äöüßÄÖÜ_.\-\+]+)';
i get this result
Array
(
[6861] => Array
(
[id] => 12322
[filename] => image_2623_йцу.JPG
[chars] => Array
(
[0] => Array
(
[0] => �¹
[1] => �†
[2] => �ƒ
)
)
)
...
[7162] => Array
(
[id] => 12699
[filename] => image_3050_Ringänderung_Service_kostenlos_Mytrauringstore.jpg
[chars] => Array
(
[0] => Array
(
[0] => �ˆ
)
)
)
)
and with this Regex
protected static $regex = '/[\xc2-\xdf][\x80-\xbf]/';
i get this Result
Array
(
[6861] => Array
(
[id] => 12322
[filename] => image_2623_йцу.JPG
[chars] => Array
(
[0] => Array
(
[0] => Ð
[1] => ¹
[2] => Ñ
[3] => Ñ
[4] => ƒ
)
)
)
...
[7162] => Array
(
[id] => 12699
[filename] => image_3050_Ringänderung_Service_kostenlos_Mytrauringstore.jpg
[chars] => Array
(
[0] => Array
(
[0] => Ì
[1] => ˆ
)
)
)
)
So with the second Regex i match the Chars that really exists in the String. But i also matches these Chars
ä ö ü ß Ä Ö Ü
but these Chars should'n match.
So how to manage this?
