Describe the bug

Basically when I save the php file I see the Formatter 'php_cs_fixer' timeout

but when I use 'f' it works

What is the severity of this bug?

minor (annoyance)

Steps To Reproduce

1. open any php file
2. :w save it
3. see the warning bellow

Expected Behavior

no working and it works

Minimal example file

any php file is the same, also you need the php-cs-fixer to be installed, which I do have and it works

Minimal init.lua

{ -- Autoformat
    'stevearc/conform.nvim',
    event = { 'BufWritePre' },
    cmd = { 'ConformInfo' },
    keys = {
      {
        '<leader>f',
        function()
          require('conform').format { async = true, lsp_format = 'fallback' }
        end,
        mode = '',
        desc = '[F]ormat buffer',
      },
    },
    opts = {
      log_level = vim.log.levels.DEBUG,
      notify_on_error = false,
      format_on_save = function(bufnr)
        -- Disable "format_on_save lsp_fallback" for languages that don't
        -- have a well standardized coding style. You can add additional
        -- languages here or re-enable it for the disabled ones.
        local disable_filetypes = { c = true, cpp = true, php = false }
        local lsp_format_opt
        if disable_filetypes[vim.bo[bufnr].filetype] then
          lsp_format_opt = 'never'
        else
          lsp_format_opt = 'fallback'
        end
        return {
          timeout_ms = 500,
          lsp_format = lsp_format_opt,
        }
      end,
      formatters_by_ft = {
        lua = { 'stylua' },
        php = { 'php_cs_fixer', 'pint', stop_after_first = true },
        -- Conform can also run multiple formatters sequentially
        -- python = { "isort", "black" },
        --
        -- You can use 'stop_after_first' to run the first available formatter from the list
        javascript = { 'prettier', stop_after_first = true },
        json = { 'prettier' },
      },
    },
  }

I've had the same issue, bumping timeout_ms from 500 to 700 is enough to get rid of it for me.

Edit: php-cs-fixer is generally slower compared to other formatters, but you can use phpactor instead intelephense, it comes bundled with php-cs-fixer and for some reason it works faster than php-cs-fixer on its own.

I am using async: true so timeout_ms is ignored, but this formatter fails constantly for me, despite working perfectly from the CLI.
