What is it
PhpSimpleRegex is an object oriented regular expressions library for PHP.
This library allows to execute preg_* functions in PHP and use the results as objects, making the use of preg_* functions testeable. PhpSimpleRegex is integrated with VerbalExpressions\PHPVerbalExpressions\VerbalExpressions, SelvinOrtiz\Utils\Flux\Flux and also MarkWilson\VerbalExpression to allow a full Object Oriented approach to Regular Expressions in PHP.
Installation
Composer:
If you want to access directly to this repo, adding this to your composer.json should be enough:
{ "require": { "mcustiel/php-simple-regex": "*" } }
Or just download the release and include it in your path.
How to use it?
This library provides a facade class that wraps most of the preg_* functions from PHP. All you need to do is to create an instance of this class and call the methods you need.
use Mcustiel\PhpSimpleRegex\Executor as RegexExecutor; $regexFacade = new RegexExecutor();
List of methods:
- MatchResult getAllMatches(mixed $pattern, string $subject, integer $offset = 0)
- Match getOneMatch(mixed $pattern, string $subject, integer $offset = 0)
- boolean match(mixed $pattern, string $subject, integer $offset = 0)
- ReplaceResult replaceAndCount(mixed $pattern, string $replacement, mixed $subject, integer $limit = -1)
- mixed replace(mixed $pattern, string $replacement, mixed $subject, integer $limit = -1)
- mixed replaceCallback(mixed $pattern, callable $callback, mixed $subject, integer $limit = -1)
- ReplaceResult replaceCallbackAndCount(mixed $pattern, callable $callback, mixed $subject, integer $limit = -1)
- array split(mixed $pattern, string $string, integer $limit = -1, bool $returnOnlyNotEmpty = false, bool $captureOffset = false, bool $captureSubpatterns = false)
- array grep(mixed $pattern, array $input)
- array grepNotMatching(mixed $pattern, array $input)
For each method, the pattern can be a string, a Flux object, or a PhpVerbalExpression object.
Examples:
getAllMatches:
try { $result = $regexFacade->getAllMatches('/\d+/', 'ab12cd34ef56'); echo 'Number of matches: ' . $result->getMatchesCount() . PHP_EOL; // Prints 3 echo 'First match: ' . $result->getMatchAt(0)->getFullMatch() . PHP_EOL; // Prints 12 // Iterate over results foreach ($result as $index => $match) { echo "Match at index {$index} is " . $match->getFullMatch() . PHP_EOL; } } catch (\Exception $e) { echo 'An error occurred executing getAllMatches'; }
getOneMatch:
try { $result = $regexFacade->getOneMatch('/\d+/', 'ab12cd34ef56'); if (!empty($result)) { echo 'Match: ' . $result->getFullMatch() . PHP_EOL; // Prints 12 } } catch (\Exception $e) { echo 'An error occurred executing getOneMatch'; }
match:
try { if ($regexFacade->match('/\d+/', 'ab12cd34ef56')) { echo 'String matches pattern.'. PHP_EOL; } else { echo 'String does not match pattern.'. PHP_EOL; } } catch (\Exception $e) { echo 'An error occurred executing match'; }
replaceAndCount:
try { // Subject can also be an array. $result = $this->executor->replaceAndCount('/\d+/', 'potato', 'ab12cd34ef56'); echo 'Number of replacements: ' . $result->getReplacements() . PHP_EOL; echo 'Replaced string: ' . $result->getResult() . PHP_EOL; } catch (\Exception $e) { echo 'An error occurred executing replaceAndCount'; }
replace:
try { // Subject can also be a string. $result = $this->executor->replaceAndCount('/\d+/', 'potato', ['ab12cd34ef56', 'ab12cd78ef90']); echo 'Replaced strings: ' . print_r($result->getResult(), true) . PHP_EOL; } catch (\Exception $e) { echo 'An error occurred executing replace'; }
replaceCallback:
try { // Subject can also be an array. $result = $this->executor->replaceCallback('/\d+/', function () { return 'potato'; }, 'ab12cd34ef56'); echo 'Replaced string: ' . $result->getResult() . PHP_EOL; } catch (\Exception $e) { echo 'An error occurred executing replaceCallback'; }
replaceCallbackAndCount:
try { // Subject can also be an array. $result = $this->executor->replaceCallback('/\d+/', function () { return 'potato'; }, 'ab12cd34ef56'); echo 'Number of replacements: ' . $result->getReplacements() . PHP_EOL; echo 'Replaced string: ' . $result->getResult() . PHP_EOL; } catch (\Exception $e) { echo 'An error occurred executing replaceCallbackAndCount'; }
