I have been trying to find a solution for past few hours but unable to do so. I have tried each and every possible solution on the Internet and this forum but nothing seems
i wasn't try in Arabic language but i was tried my code in my last project site, the site was available in multi languages. you may just add php function urlencode for save content in database and for retrieving data content use urldecode function.
$content=urlencode($_POST["content"]);
echo $content;
$sql="update home set content='$content'";
for retrieve/print
echo urldecode($data['content']);
or if you don't want this just change column collation type "UTF8_GENERAL_CI"
