JS:将JS对象格式化为php语法形式(完美支持无unicode编码匹配的正则)

/*** 格式化Object数据为php语法形式* @param {*} obj 任意数据* @param {String} spaceLen 缩略符长度：必须在2~65536之间，否则默认为2* @return {String} 格式化后的PHP语法字符串*/
function formatToPhp(obj, spaceLen) {formatToPhp = function (obj, spaceLen) {const space =spaceLen >= 2 && spaceLen <= 65536 ? ' '.repeat(spaceLen) : '  'return formatToPhp.fn(obj, '', (formatToPhp.space = space))}formatToPhp.toStr = function (scalar) {scalar = JSON.stringify(scalar).split('\'').join('\\\'')return '\'' + scalar.slice(1, -1) + '\''}formatToPhp.fn = function (obj, minSpace, maxSpace) {const t = typeof objif (t === 'object') {const nextSpace = maxSpace + this.spaceswitch (Object.prototype.toString.call(obj)) {case '[object Array]':return obj.length === 0? '[]': `[\n${maxSpace}${obj.map((item) => this.fn(item, maxSpace, nextSpace)).join(`,\n${maxSpace}`)}\n${minSpace}]`case '[object Object]':const keys = Object.keys(obj)return keys.length === 0? '[]': `[\n${keys.map((key) => maxSpace + this.toStr(key) + ' => ' + this.fn(obj[key], maxSpace, nextSpace)).join(',\n')}\n${minSpace}]`case '[object RegExp]':return '\'' + (obj + '').split('\'').join('\\\'') + '\''}return null} else if (t === 'string') return this.toStr(obj)return t === 'function' ? 'function(){}' : JSON.stringify(obj) || null}return formatToPhp(obj, spaceLen)
}

注意：正则在匹配unicode编码时需要手动修改。例如：

  JS正则：/[\u4e00-\u9fa5]+/

  PHP正则：/[\x{4e00}-\x{9fa5}]+/u
