+ php quantifier - PHP

Introduction

This is a PHP package that is designed to help developers add quantifiers to regular expressions in order to match patterns more accurately.

Regular expressions are powerful tools for string pattern matching, but sometimes they can be too vague or too strict. Quantifiers help to specify the number of occurrences of a pattern, making it easier to match the desired pattern.

With this package, developers can add quantifiers to their regular expressions with ease, making their code more efficient and accurate.

Usage

To use this package, simply include the + php quantifier library in your PHP project using composer:

composer require amline/php-quantifier

Then, use the +phpQuantifier class to add quantifiers to your regular expressions:

use Amline\PhpQuantifier;

$pattern = '/[a-z]{1,3}/'; // matches any lowercase letter between 1 and 3 times
$quantifier = new PhpQuantifier($pattern);

echo $quantifier->getRegex(); // returns '/[a-z]{1,3}/'
Examples

Here are some examples of how the +phpQuantifier library can be used:

Match two or more consecutive digits
$pattern = '/\d{2,}/'; // matches two or more consecutive digits
$quantifier = new PhpQuantifier($pattern);

echo $quantifier->getRegex(); // returns '/\d{2,}/'
Match a number with up to two decimal places
$pattern = '/\d+(\.\d{1,2})?/'; // matches a number with up to two decimal places
$quantifier = new PhpQuantifier($pattern);

echo $quantifier->getRegex(); // returns '/\d+(\.\d{1,2})?/'
Match an email address
$pattern = '/[a-zA-z0-9._%+-]+@[a-z0-9.-]+\.[a-z]{2,}/'; // matches an email address
$quantifier = new PhpQuantifier($pattern);

echo $quantifier->getRegex(); // returns '/[a-zA-z0-9._%+-]+@[a-z0-9.-]+\.[a-z]{2,}/'
Conclusion

The +phpQuantifier library is a useful tool for PHP developers who want to improve their regular expression pattern matching. With this library, developers can easily add quantifiers to their regular expressions, making their code more efficient and accurate.
