Solution-Guzzle idn_to_ascii(): INTL_IDNA_VARIANT_2003 is deprecated

Guzzle is a PHP package that use by many frameworks like CakePHP. With PHP > 7, guzzlehttp gives an error like idn_to_ascii()  is deprecated. So we can solve these issues by

1) Downgrade Guzzle
2) Reinstall Packages
3) Upgrade PHP Version

If your issue still exists and then we can try to avoid deprecated errors by adding @ before idn_to_ascii() function, it will prevent to generate deprecation errors for this function. Yes we do not make changes in vendor files and also it's not a good way to handle error but sometimes it works

and that's all we wanna do.

Example:
For me its showing error like

idn_to_ascii(): INTL_IDNA_VARIANT_2003 is deprecated
 [ROOT/vendor/guzzlehttp/guzzle/src/Utils.php, line 35]

SO i have opened Utils.php file and added @ before function like below code

BEFORE

 public static function idnUriConvert(UriInterface $uri, $options = 0)
    {
        if ($uri->getHost()) {
            $idnaVariant = defined('INTL_IDNA_VARIANT_UTS46') ? INTL_IDNA_VARIANT_UTS46 : 0;
            $asciiHost = $idnaVariant === 0
                ?  idn_to_ascii($uri->getHost(), $options)
                :  idn_to_ascii($uri->getHost(), $options, $idnaVariant, $info);

AFTER

 public static function idnUriConvert(UriInterface $uri, $options = 0)
    {
        if ($uri->getHost()) {
            $idnaVariant = defined('INTL_IDNA_VARIANT_UTS46') ? INTL_IDNA_VARIANT_UTS46 : 0;
            $asciiHost = $idnaVariant === 0
                ?  @idn_to_ascii($uri->getHost(), $options)
                :  @idn_to_ascii($uri->getHost(), $options, $idnaVariant, $info);
