This library implements an fully compatible PHP version of [big-bit-mask](https://github.com/ASolomatin/big-bit-mask) - the bitmask serializable into a base64-like, url-safe string. Other platform compatibility ---------------------------- [](#other-platform-compatibility) PlatformRepositoryPackageJavaScript / TypeScript[big-bit-mask](https://github.com/ASolomatin/big-bit-mask)[NPM](https://www.npmjs.com/package/big-bit-mask).NET[BigBitMask.NET](https://github.com/ASolomatin/BigBitMask.NET)[NuGet](https://www.nuget.org/packages/BigBitMask.NET/)Install ------- [](#install) ``` > composer require asolomatin/php-big-bit-mask ``` Usage ----- [](#usage) ### Namespace [](#namespace) ``` use asolomatin\BigBitMask\BitMask; ``` ### What next? [](#what-next) Now we can create new empty bitmask ``` $bitmask = new BitMask(); ``` or load it from string ``` $bitmask = new BitMask("CE3fG_gE-56"); //Let's see what inside now $content = ""; for ($i = 0; $i < 11 * 6; $i++) { // Each character contains 6 bits, as in base64 $content .= $bitmask[$i] ? "1" : "0"; } echo $content.PHP_EOL; ``` output: `010000001000111011111110011000111111000001001000011111100111010111` Then we can change some bits and get back our string representation ``` $bitmask[65] = false; $bitmask[64] = false; $bitmask[63] = false; $bitmask[61] = false; $bitmask[19] = false; $bitmask[5] = true; echo strval($bitmask).PHP_EOL; ``` output: `iE3dG_gE-5` #### But what if I want to have a named flags? [](#but-what-if-i-want-to-have-a-named-flags) You can extend BitMask class with your model: ``` class MyCoolCheckboxes extends BitMask { const CHECKBOX_0 = 0; const CHECKBOX_1 = 1; const CHECKBOX_2 = 2; const CHECKBOX_3 = 3; const CHECKBOX_4 = 4; const CHECKBOX_5 = 5; const CHECKBOX_6 = 6; const CHECKBOX_7 = 7; const CHECKBOX_8 = 8; const CHECKBOX_9 = 9; // Some magic public function __set(string $name, bool $value) { call_user_func([$this, "set".ucfirst($name)], $value); } public function __get(string $name): bool { return call_user_func([$this, "set".ucfirst($name)]); } public function getCheckbox0(): bool { return $this[self::CHECKBOX_0]; } public function setCheckbox0(bool $value) { $this[self::CHECKBOX_0] = $value; } public function getCheckbox1(): bool { return $this[self::CHECKBOX_1]; } public function setCheckbox1(bool $value) { $this[self::CHECKBOX_1] = $value; } public function getCheckbox2(): bool { return $this[self::CHECKBOX_2]; } public function setCheckbox2(bool $value) { $this[self::CHECKBOX_2] = $value; } public function getCheckbox3(): bool { return $this[self::CHECKBOX_3]; } public function setCheckbox3(bool $value) { $this[self::CHECKBOX_3] = $value; } public function getCheckbox4(): bool { return $this[self::CHECKBOX_4]; } public function setCheckbox4(bool $value) { $this[self::CHECKBOX_4] = $value; } public function getCheckbox5(): bool { return $this[self::CHECKBOX_5]; } public function setCheckbox5(bool $value) { $this[self::CHECKBOX_5] = $value; } public function getCheckbox6(): bool { return $this[self::CHECKBOX_6]; } public function setCheckbox6(bool $value) { $this[self::CHECKBOX_6] = $value; } public function getCheckbox7(): bool { return $this[self::CHECKBOX_7]; } public function setCheckbox7(bool $value) { $this[self::CHECKBOX_7] = $value; } public function getCheckbox8(): bool { return $this[self::CHECKBOX_8]; } public function setCheckbox8(bool $value) { $this[self::CHECKBOX_8] = $value; } public function getCheckbox9(): bool { return $this[self::CHECKBOX_9]; } public function setCheckbox9(bool $value) { $this[self::CHECKBOX_9] = $value; } } $checkboxes = new MyCoolCheckboxes(); $checkboxes->checkbox5 = true; $checkboxes->checkbox7 = true; $checkboxes->checkbox8 = true; echo strval($checkboxes).PHP_EOL; ``` output: `gG` --- License ------- [](#license) **[MIT](https://github.com/ASolomatin/php-big-bit-mask/blob/master/LICENSE)** Copyright (C) 2020 Aleksej Solomatin ### Health Score 30 — LowBetter than 65% of packages Maintenance29 Infrequent updates — may be unmaintained Popularity18 Limited adoption so far Community8 Small or concentrated contributor base Maturity54 Maturing project, gaining track record Bus Factor1 Top contributor holds 100% of commits — single point of failure How is this calculated?**Maintenance (25%)** — Last commit recency, latest release date, and issue-to-star ratio.
