Hi,
As I mentioned in my original posting, I am not a PHP programmer; But,
it seems that for keyboard input functions you WILL have to convert
UTF-8 to HTML encoding if you want to use your function; for example
by calling a function like htmlentities() or utf8_decode() before
calling utf8_to_int(). The pseudo code looks like this:
if (input is in UTF-8) { # for example input is from a Linux keyboard
$str = htmlentities($str, ENT_COMPAT, "UTF-8" );
}
$intvalue = utf8_ot_int($str);
I've included the function again; I added the extra code to check for "x in set y"
test. Also note the use of the built-in strtr() function. These builtins usually
are more efficient (written in C) and are faster. This code has not been tested.
function utf8_to_int($str)
{
$transtbl = array (
"۰" => '0',
"۱" => '1',
"۲" => '2',
"۳" => '3',
"۴" => '4',
"۵" => '5',
"۶" => '6',
"۷" => '7',
"۸" => '8',
"۹" => '9'
);
foreach ($transtbl as $key => $value) {
if ($key == $str) { # it has an HTML
encoded numeric
$str = strtr($str, $transtbl); # convert all of them to ASCII
[0-9]
return (int) $str; # convert to whole
thing to integer
}
}
return (int) $str;
}
One last thing, this function (and your version) has a fatal flaw. Do you
want to guess what it is?
Hint: What happens if the string is "ABCDE"? What is the difference in the
return value from the function for the strings "ABCD" and "۰"?

Hi dears.
Mr.Tavakkolian was helping me until my function completed.
This function converts utf8(digit) to integer.
$farsi_table_linux=array("NONE",
"۰",
"۱",
"۲",
"۳",
"۴",
"۵",
"۶",
"۷",
"۸",
"۹");
function search_index_array($str)
{
global $farsi_table;
for ($i=0;$i<11;$i++)
{
if ($farsi_table[$i]==$str )
return $i;
}
return FALSE;
}// end of search_index_array
////////////////////////////////
function utf8_to_int($str)
{
$len=strlen($str);
$out="";
$char=explode(";",$str);
for ($i=0;$i<$len;$i++)
{
$char[$i].=";";
if (search_index_array($char[$i])!=False)
$out.=search_index_array($char[$i])-1;
}//end of for ($i)
return $out;
}//end of utf8_to_int
When i call utf8_to_int("۰"."۹") ,this return 09 ,But When i enter a
number(utf8) via keyboard,This function return 0.
Please guide me that i how enter a number via keyboard(persian) & i get true answer.
--regards
