README

A simple, lightweight, dependency free PHP library for predicates and callbacks for dates, strings, numbers, versions etc

Features

• Suite of predicates
• Convienence callbacks for things like easier array filtering
• No namespace means no worrying about use statements and qualifying function names
• Deprecation notices for when/if php adds a new function by the same name
• Built-in locale awareness (internationalization) for most predicates
• Predicate Categories
  • General Use
  • Dates
  • Numbers
  • Strings
  • PHP (versions)
  • Platform
  • Server
  • Callbacks

Usage

• Ensure to have intl extension enabled in your php.ini
• > composer require ft/predicates

Examples

$array = [null,0,1,2,3,4,5,'one','two'];

array_filter($array, 'is_positive'); // [1,2,3,4,5]
array_filter($array, is_and('is_positive', is_not('is_truthy'))); // [2,3,4,5]
array_filter($array, is_xor('is_positive', 'is_truthy')); // [2,3,4,5]

is_month_name("january") //true

A lot of effort has been put into making the predicates locale aware. An example of built-in support:

putenv("lang=kr_KR");

is_month_name('february') //true
is_month_name('이월') //true

Note Not all languages may be supported, as this is a work in progress. To help us add support, please submit a language in discussions!
