On this page you can find all versions of the php package lsr/helpers. It is possible to download/install these versions without Composer. Possible dependencies are resolved automatically.
FAQ
Example:
In general, it is recommended to use always a project to download your libraries. In an application normally there is more than one library needed.
- Some hosting areas are not accessible by a terminal or SSH. Then it is not possible to use Composer.
- To use Composer is sometimes complicated. Especially for beginners.
- Composer needs much resources. Sometimes they are not available on a simple webspace.
- If you are using private repositories you don't need to share your credentials. You can set up everything on our site and then you provide a simple download link to your team member.
- Simplify your Composer build process. Use our own command line tool to download the vendor folder as binary. This makes your build process faster and you don't need to expose your credentials for private repositories.
Informations about the package helpers
LSR Helpers
lsr/helpers provides string conversion, timing and CSRF helpers and Composer-autoloaded global utility functions for LSR applications.
Requirements
- PHP
>=8.4andext-simplexml. lsr/interfaces^0.3.0, Nette Utils^4.0, Gettext^5.7and Tracy^2.9(installed by Composer).Strings::toSnakeCase()usesmb_strtolower(): provideext-mbstringor a compatible polyfill when using that method.- Framework-specific helpers need application setup:
TokenHelpertakes aLsr\Interfaces\SessionInterface,Timerreads thePRODUCTIONconstant, andsvgIcon()reads files beneathASSETS_DIR . 'icons/'.
Installation
String and numeric helpers
Strings extends Nette\Utils\Strings. The camel/Pascal helpers transform underscores and spaces; they are not general-purpose word tokenizers.
includes/functions.php is loaded automatically by Composer and defines each global helper only if its name is not already defined. It includes map(), ratio(), first(), last(), not_empty(), trailingSlashIt(), alert() and svgIcon(). Do not include the file manually. map() does not clamp its result and requires distinct input bounds. alert() returns HTML without escaping its arguments; escape untrusted content before using it.
Application integration
Lsr\Helpers\Csrf\TokenHelperstores random form tokens through the injected session contract and compares tokens withhash_equals(). Prefer this class over the deprecated globalformToken(),isTokenValid()andformValid()functions. For a prefixedformToken($prefix), pass the expected token explicitly toisTokenValid($submitted, $expected); its implicit lookup uses the unprefixed session key.formValid()expects an HMAC derived from the form name, not the raw token returned byformToken().Lsr\Helpers\Tools\Timerexposes staticstart(),startIncrementing(),stop()andget()methods. DefinePRODUCTIONbefore calling it; timing is disabled when that constant is true.svgIcon()requires an application-definedASSETS_DIRending in a directory separator and existing SVG files under itsicons/directory. Use trusted icon names and SVG assets.
Development
CI runs on PHP 8.4 and 8.5. Install development dependencies and run the same three checks locally:
These use phpunit.xml. The suite exercises array helpers without external services. composer analyze and composer test remain available as local shortcuts.
Run composer cs to check PHP coding style without changing files and composer cs:fix to apply fixes (composer cbf is an alias). PHP CS Fixer uses .php-cs-fixer.php.
