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.

API Reference
Character Analysis Methods
checkVowels(string $string): int
Counts lowercase vowels (a, e, i, o, u) in the given string.
- Parameter:
$string- The input string to analyze - Returns: Integer count of vowels found
checkConsonates(string $string): int
Counts lowercase consonants (non-vowel letters) in the given string.
- Parameter:
$string- The input string to analyze - Returns: Integer count of consonants found
checkNumber(string $str): int
Counts numeric digits (0-9) in the given string.
- Parameter:
$str- The input string to analyze - Returns: Integer count of digits found
upper(string $string): int
Counts uppercase letters (A-Z) in the given string.
- Parameter:
$string- The input string to analyze - Returns: Integer count of uppercase letters found
lower(string $string): int
Counts lowercase letters (a-z) in the given string.
- Parameter:
$string- The input string to analyze - Returns: Integer count of lowercase letters found
noalpha(string $string): int
Counts non-alphanumeric characters (special characters, spaces, punctuation) in the given string.
- Parameter:
$string- The input string to analyze - Returns: Integer count of special characters found
calculateWordLetterAverage(string $string): int
Calculates the average number of characters per word in the given string.
- Parameter:
$string- The input string containing words - Returns: Integer average (rounded up) using
ceil()
Result Management Methods
set(string $key, string $value): void
Stores or accumulates character findings by type.
- Parameter:
$key- The character type identifier - Parameter:
$value- The character to store
get(string $key): array
Retrieves stored characters of a specific type.
- Parameter:
$key- The character type identifier - Returns: Array of characters, or empty array if not found
getAll(): array
Retrieves all collected character results.
- Returns: Associative array of all character collections

Important Notes
Character Case Sensitivity
The library only counts lowercase vowels and consonants (a-z, not A-Z). Use the upper() and lower() methods separately for case analysis.
Examples
Method Naming
Note: The method is named checkConsonates (not "checkConsonants") for historical reasons, but functions identically to a consonant counter.
Performance
- Lightweight: Zero external dependencies
- Efficient: Uses native PHP functions for character analysis
- Memory: Minimal memory footprint, suitable for batch processing
