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

public static function isArabic($string){
    if(preg_match('/\p{Arabic}/u', $string))
        return true;
    return false;
}

Answer 2

The PHP Text_LanguageDetect library is able to detect 52 languages. It's unit-tested and installable via composer and PEAR.

Answer 3

I'm not aware of a PHP solution for this, no.

The Google Translate Ajax APIs may be for you, though.

Answer 4

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;
        }
    }

Answer 5

You can use function, which i have written for you:

<?php
/**
 * Return`s true if string contains only arabic letters.
 *
 * @param string $string
 * @return bool
 */
function is_arabic($string)
{
    return (preg_match("/^\p{Arabic}/i", $string) > 0);
}

But please, check it, before use.

Your question: "How do I detect if an input string is Arabic?" And i have answered to it, what`s wrong?

Read this - Detect language from string in PHP

[EDIT 3]

Excuse, i rewrite function to this, try it:

function is_arabic($subject)
{
    return (preg_match("/^[\x0600-\x06FF]/i", $subject) > 0);
}

Answer 6

I assume you're referring to a Unicode string... in which case, just look for the presence of any character with a code between U+0600–U+06FF (1536–1791) in the string.
