how to get actual number of unicode character?

[markthien]

Hi guys,

 

I got a textarea let user enter their remark and I need to get the length of user entered remark.

Hence, I use strlen but it's no right when user enter both chinese and alphabet together like:

 

$tmp = 'Hello dear'; // string from textarea

$len = strlen($tmp); // this is correct where it return 10

 

$tmp = 'Hello dear 双皮奶'; // string from textarea

$len = strlen($tmp); // this is not really correct where it return 19

 

I need it to return length of 13 for the 2nd one. Hwo to do that? thanks!

 

Cheers,

Mark Thien

strlen(utf8_decode($tmp))

[inversesoft123]

function unistrlen($tmp)

{

  $foo = preg_split("//u", $tmp);

  $foo1 = -2;

  foreach ($foo as $tmp)

    $foo1++;

  return $foo1;

}

 

I am not sure abut this dirty function but try

inversesoft123, is there any reason you decided to mention using preg_split over your earlier suggestion of strlen/utf8_decode?
