# Errors parsing Standard input code: Bitwise OR ‘|’

 * I hope someone can assist me with identifying why WordPress rejects the “|” (
   pipes) used as bitwise OR statements for the variable types.
 *     ```
       if (!function_exists('mb_convert_encoding')) {
           function mb_convert_encoding(array|string $string, string $to_encoding, array|string|null $from_encoding = null): array|string|false { return p\Mbstring::mb_convert_encoding($string, $to_encoding, $from_encoding); }
       }
       ```
   
 * I am running in PHP 7.3 and have pulled in the Twig/Symfony composer libraries(
   v3.1.1) which requires PHP >=7.2.5.
 * Every time I try and commit the Twig/Symfony libraries to my plugin’s SVN repository,
   it results in the following:
 *     ```
       svn: E165001: Commit failed (details follow):
       svn: E165001: Commit blocked by pre-commit hook (exit code 1) with output:
       ***********************************
       PHP error in: starfish-reviews/tags/2.3.28/composer/vendor/symfony/polyfill-mbstring/bootstrap80.php:
       Parse error: syntax error, unexpected '|', expecting variable (T_VARIABLE) in Standard input code on line 15
       Errors parsing Standard input code
       ***********************************
       ```

 * I think the linter was only updated to 7.1 a couple of months ago.
    I don’t think
   there’s a schedule for updating it.

 * The WordPress Plugins team responded with this. Thank you Team!

 * Why is WP such a tremendously shit platform to develop…
 * Thanks for sharing this “insight” from the WP team.

 * Hi guys.
 * Instead of downgrading you could just remove type annotations as part as your
   workflow via a sed command.
 * I have a file with replacements and I do this:
 *     ```
       find . -type f -name bootstrap80.php -exec sed -i .bak -f bootstrap80.php.sed {} +
       find . -name "*.bak" -exec rm {} +
       ```
   
 * The sed file looks like:
 *     ```
       s/: bool//g
       s/: string\|false//g
       ```

 * For anyone else running into this, the latest unproblematic version of the package
   is 1.20.0. You can fix it in the composer.json:
 *     ```
       {
           "require": {
               "symfony/polyfill-mbstring": "1.20.0",
           },
       }
       ```
