Answer 1

you can use transliteration on any string you want to convert to latin-similar characters. My very-custom transliteration code looks like that:
// convert a utf8-encoded string into latin representative
function transliterate_string($params=array())
{
// PARAMS: "string", "language"
// 0) fill-in "native" chars by language and their "latin" representative
$SP_trans = array(
"ae"=>array("native"=>"ة,بْ,...","latin"=>"a,b,..."),
...other langs if you want
);
// 1) break "native" & "latin" strings
$nc = explode(",",$SP_trans[ $params["language"] ]["native"]);
$lc = explode(",",$SP_trans[ $params["language"] ]["latin"]);
// 2) convert to lower first
$string = mb_strtolower($params["string"],"utf-8");
// 3) loop each character
mb_internal_encoding("UTF-8");
for($x=0,$sz=mb_strlen($string);$x<$sz;$x++) {
$char = mb_substr($string,$x,1);
$index = array_search($char,$nc);
$out[$x] = ($index===FALSE ? $char : $lc[$index]);
}
return trim(implode("",$out));
}
the function just scans a string and convert each character of specific character
set into latin in a custom way. Then you can safely save the file as latin.

It will be better to rename the image name using time stamp
$imgname = time().'.'.'jpg';
$imgtmpname=$_FILES['file']['tmp_name'];
$fullpath= $path.$imgname;
$filename = $imgname;
move_uploaded_file($imgtmpname,$fullpath);
and also store the $imgname in the database so we can fetch the image by this name..It will also avoid the name conflict between images as the timestamps keep changing.
