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 regex
Making regex great again
Php's built in preg_* functions require some odd patterns like passing variables by reference and treating false or null values as errors. spatie/regex provides a cleaner interface for preg_match, preg_match_all, preg_replace and preg_replace_callback.

Installation
You can install the package via composer:
Usage
Matching a pattern once
Matches a pattern on a subject. Returns a MatchResult object for the first match.
MatchResult::hasMatch(): bool
Checks if the pattern matches the subject.
MatchResult::result(): string
Return the full match that was made. Returns null if no match was made.
MatchResult::group(int $id): string
Return the contents of a captured group (with a 1-based index). Throws a RegexFailed exception if the group doesn't exist.
Matching all occurences of a pattern
Matches a pattern on a subject. Returns a MatchAllResult object containing all matches.
MatchAllResult::hasMatch(): bool
Checks if the pattern matches the subject.
MatchAllResult::results(): array
Returns an array of MatchResult objects.
Replacing a pattern in a subject
Replaces a pattern in a subject. Returns a ReplaceResult object.
ReplaceResult::result(): mixed
Regex::replace also works with callables. The callable will receive a MatchResult instance as it's argument.
Patterns, replacements and subjects can also be arrays. Regex::replace behaves exactly like preg_replace in those instances.
Error handling
If anything goes wrong in a Regex method, a RegexFailed exception gets thrown. No need for checking preg_last_error().
