Note that we intend to implement the PHP // note 1: behavior by default if IE ever does allow it; only gives shallow copy since // note 1: is by reference in PHP anyways // note 1: Since JS objects' keys are always strings, and (the // note 1: default) SORT_REGULAR flag distinguishes by key type, // note 1: if the content is a numeric string, we treat the // note 1: "original type" as numeric. // example 1: var $data = {d: 'lemon', a: 'orange', b: 'banana', c: 'apple'} // example 1: asort($data) // example 1: var $result = $data // returns 1: {c: 'apple', b: 'banana', d: 'lemon', a: 'orange'} // example 2: ini_set('locutus.sortByReference', true) // example 2: var $data = {d: 'lemon', a: 'orange', b: 'banana', c: 'apple'} // example 2: asort($data) // example 2: var $result = $data // returns 2: {c: 'apple', b: 'banana', d: 'lemon', a: 'orange'} const strnatcmp = require('../strings/strnatcmp') const i18nlgd = require('../i18n/i18n_loc_get_default') const valArr = [] let valArrLen = 0 let k let i let sorter let sortByReference = false let populateArr = {} const $global = typeof window !== 'undefined' ? window : global $global.$locutus = $global.$locutus || {} const $locutus = $global.$locutus $locutus.php = $locutus.php || {} $locutus.php.locales = $locutus.php.locales || {} switch (sortFlags) { case 'SORT_STRING': // compare items as strings sorter = function (a, b) { return strnatcmp(a, b) } break case 'SORT_LOCALE_STRING': // compare items as strings, based on the current locale // (set with i18n_loc_set_default() as of PHP6) var loc = i18nlgd() sorter = $locutus.php.locales[loc].sorting break case 'SORT_NUMERIC': // compare items numerically sorter = function (a, b) { return a - b } break case 'SORT_REGULAR': // compare items normally (don't change types) break default: sorter = function (a, b) { const aFloat = parseFloat(a) const bFloat = parseFloat(b) const aNumeric = aFloat + '' === a const bNumeric = bFloat + '' === b if (aNumeric && bNumeric) { return aFloat > bFloat ? 1 : aFloat < bFloat ? -1 : 0 } else if (aNumeric && !bNumeric) { return 1 } else if (!aNumeric && bNumeric) { return -1 } return a > b ? 1 : a < b ? -1 : 0 } break } const iniVal = (typeof require !== 'undefined' ? require('../info/ini_get')('locutus.sortByReference') : undefined) || 'on' sortByReference = iniVal === 'on' populateArr = sortByReference ? inputArr : populateArr // Get key and value arrays for (k in inputArr) { if (inputArr.hasOwnProperty(k)) { valArr.push([k, inputArr[k]]) if (sortByReference) { delete inputArr[k] } } } valArr.sort(function (a, b) { return sorter(a[1], b[1]) }) // Repopulate the old array for (i = 0, valArrLen = valArr.length; i < valArrLen; i++) { populateArr[valArr[i][0]] = valArr[i][1] } return sortByReference || populateArr }
