PHP Fatal error: Uncaught ErrorException: Client error: `POST http://translate.google.com/translate_a/ about google-translate-php HOT 3 CLOSED

This, for example, can be a method for splitting and translating long texts:

        $translatedText = '';
        $cutIndex = 0;
        $divider = PHP_EOL; // for example, I have a lot of new lines in my text
        
        while ( strlen($text) > $cutIndex ) {
            $startIndex = $cutIndex;
            if (strlen($text) < $cutIndex + 4999)
                $cutIndex = strlen($text);
            else
                $cutIndex = strrpos( substr($text,0,$startIndex+4999), $divider );
            $translatedText .= $tr->translate(substr($text, $startIndex, $cutIndex-$startIndex).$divider);
         }

         // return $translatedText;

As a lot of people have noticed (for example), a few weeks ago, Google stopped allowing long texts on Google Translate, and this is what causes the '413 Request Entity Too Large' error. As you can read on forums, and as I also can verify, Google now allows a maximum of 5000 characters. These changes were maybe made to support the new, more accurate translation engine. If you want to translate a longer text, you can split it to shorter parts, and translate them one-by-one.

About the uncaught exception: You should wrap your code in a try-catch block.

@ordinov Thanks for your code, but I think this will not work with special characters, as basic string functions fail to work on them in PHP. Fortunately we have multibyte ( mb_ ) functions. Example:
strlen('café'); //output: 5
mb_strlen('café'); //output: 4

Also if we are talking about splitting SIMPLE, non-multibyte texts at X characters into arrays, you can use str_split($str, $length), however this will also fail on special characters. Example:
str_split('café', 1); //output: array( c, a, f, �, � )

Unfortunately there is no alternative multibyte function for str_split, but you can use this custom function below to split multibyte strings at every X characters:

function mb_str_split($string, $split_length = 1, $encoding = null)
{
    if (is_null($encoding)) {
        $encoding = mb_internal_encoding();
    }

    if ($split_length < 1) {
        return false;
    }

    $return_value = array();
    $string_length  = mb_strlen($string, $encoding);

    for ($i = 0; $i < $string_length; $i += $split_length)
    {
        $return_value[] = mb_substr($string, $i, $split_length, $encoding);
    }

    return $return_value;
}

Example usage: mb_str_split('café', 1); //output: array( c, a, f, é )
