Custom php-cs-fixer script to make it runnable with stdout

php-cs-fixer-std.php

#!/usr/local/bin/php
<?php

// Inspired from https://gist.github.com/Epskampie/427c512722b8e6c4cbf5f1340b87986b
// To use this script:
// - Change #!/usr/local/bin/php to your PHP binary path
// - chmod +x php-cs-fixer-std.php
// - Make symlink: ln -s ~/Downloads/php-cs-fixer-std.php /usr/local/bin/php-cs-fixer-std
// - Use: php-cs-fixer-std fix --rules=@Symfony src/PhpFile.php
// - This supports only one file and --debug flag to see the file content before and after the fix
