PHP port of regexpbuilderjs
RegExpBuilder integrates regular expressions into the programming language, thereby making them easy to read and maintain. Regular Expressions are created by using chained methods and variables such as arrays or strings.
composer req gherkins/regexpbuilderphp
Or download the appropriate release and require RegExpBuilder.php
and RegExp.php
from /src
.
