PHP: How do I detect if an input string is Arabic

Question

Is there a way to detect the language of the data being entered via the input field?

Answer 1

This function checks whether the entered line/sentence is arabic or not. I trimmed it first then check word by word calculating the total count for both.

function isArabic($string){
        // Initializing count variables with zero
        $arabicCount = 0;
        $englishCount = 0;
        // Getting the cleanest String without any number or Brackets or Hyphen
        $noNumbers = preg_replace('/[0-9]+/', '', $string);
        $noBracketsHyphen = array('(', ')', '-');
        $clean = trim(str_replace($noBracketsHyphen , '', $noNumbers));
        // After Getting the clean string, splitting it by space to get the total entered words 
        $array = explode(" ", $clean); // $array contain the words that was entered by the user
        for ($i=0; $i <= count($array) ; $i++) {
            // Checking either word is Arabic or not
            $checkLang = preg_match('/\p{Arabic}/u', $array[$i]);
            if($checkLang == 1){
                ++$arabicCount;
            } else{
                ++$englishCount;
            }
        }
        if($arabicCount >= $englishCount){
            // Return 1 means TRUE i-e Arabic
            return 1;
        } else{
            // Return 0 means FALSE i-e English
            return 0;
        }
    }
