PHP : Remove words less than 3 characters in unicode text

Question

I use these regex to remove words less than 3 characters :

$str = preg_replace(\"!\\\\b\\\\w{1,3}\\\\b!\", \"\", $str);  

and

$         


        

Answer 1

Use the u modifier for UTF-8 support:

/\b\w{1,2}\b/u

Answer 2

function RemoveLess($String,$Char=2)
{

    $StringArray=explode (" ",$String);

    foreach ($StringArray as &$Word) 
    {
        if (mb_strlen($Word,"UTF-8")>$Char)
        {
            $Str.=$Word." ";
        }
    }

    return trim($Str);

}


$text="any text here - لا اله إلا الله محمد رسول الله";

echo RemoveLess($text);
