Remove Arabic diacritic

I want php to convert this ...

Text : الْحَمْدُ لِلَّهِ رَبِّ الْعَالَمِينَ
converted to : الحمد لله رب العالمين

I'm not sure where to start or how to go about it. I don't know at all. I did some research, found this link http://www.suhailkaleem.com/2009/08/26/remove-diacritics-from-arabic-text-quran/ but it doesn't use php. I would like to use php and convert the above text to converted text. I want to remove any diacritical mark from user input of Arabic text

Diacritical characters in Arabic combine characters , which means that it is enough to find them easily. It is not necessary to have a substitution rule for every possible consonant with every possible vowel, which is a bit tedious.

Here's a working example that outputs what you need:



header('Content-Type: text/html; charset=utf-8', true);
$string = 'الْحَمْدُ لِلَّهِ رَبِّ الْعَالَمِينَ';

$remove = array('ِ', 'ُ', 'ٓ', 'ٰ', 'ْ', 'ٌ', 'ٍ', 'ً', 'ّ', 'َ');
$string = str_replace($remove, '', $string);

echo $string; // outputs الحمد لله رب العالمين

What is the meaning of the array $remove

. It looks weird because there is a combination character between the quotes '

, so it changes one of those single quotes. This may need to be saved in the same character encoding as your text.

try it:



$string = 'الْحَمْدُ لِلَّهِ رَبِّ الْعَالَمِينَ';
$string = preg_replace("~[\x{064B}-\x{065B}]~u", "", $string);
echo $string; // outputs الحمد لله رب العالمين

I don't speak Arabic, but I think you can make some character set in the alphabet:

function remap($string) {
    $remap = [
        'ą' => 'a',
        'č' => 'c',
        /* ... Arabic alphabet remap */
    ];
    return str_replace(array_keys($remap), $remap, $string);
}

echo remap('ąčasdadfg'); // => acasdadfg

Try this code, it works fine:

$unicode = [
            "~[\x{0600}-\x{061F}]~u",   
            "~[\x{063B}-\x{063F}]~u",   
            "~[\x{064B}-\x{065E}]~u",   
            "~[\x{066A}-\x{06FF}]~u",   
        ];

$str = preg_replace($unicode, "", $str);
