如果您要使用PHP格式化令牌来格式化ECMAScriptDate对象，那么类似以下内容的方法可能会有所帮助。它支持除时区名称之外的所有标记。我认为您不能仅使用浏览器中的javascript就能可靠地做到这一点，尽管诸如node.js之类的功能可能可以做到。

还有一些功能，例如是否遵守夏令时并生成RFC 2822格式字符串，但是我认为它们很容易添加。它支持带引号的字符，因此您可以构建类似以下的字符串：

P.format(date, 'jS \\o\\f F, Y') // 1st of August, 2019

任何与令牌不匹配的字符都将被复制到输出字符串（例如，上面的空格和逗号）。

// Parser and formatter using PHP tokens
let P = function(global) {

  let P = {lang: 'en-GB'};

  // Format tokens and functions
  let tokens = {

    // DAY
    // day of month, pad to 2 digits
    d: d => pad(d.getDate()),
    // Day name, first 3 letters
    D: d => getDayName(d).substr(0,3),
    // day of month, no padding
    j: d => d.getDate(),
    // Full day name
    l: d => getDayName(d),
    // ISO weekday number (1 = Monday ... 7 = Sunday)
    N: d => d.getDay() || 7,
    // Ordinal suffix for day of the month
    S: d => getOrdinal(d.getDate()),
    // Weekday number (0 = Sunday, 6 = Saturday)
    w: d => d.getDay(),
    // Day of year, 1 Jan is 0
    z: d => {
      let Y = d.getFullYear(),
