Most links point to interfaces for clarity, but abstract classes and concrete implementations can be found in the same folder where relevant. All tests are located in the [Tests](https://github.com/youlweb/JulLib/blob/master/src/Lib/Tests) folder. Collection ---------- [](#collection) - [Buffer](https://github.com/youlweb/JulLib/blob/master/src/Lib/Collection/Buffer/BufferInterface.php) A fixed size, iterable F.I.F.O object buffer. - [Collection](https://github.com/youlweb/JulLib/blob/master/src/Lib/Collection/CollectionInterface.php) An iterable set of objects, complete with filter, sort, etc. Entity ------ [](#entity) - [Entity](https://github.com/youlweb/JulLib/blob/master/src/Lib/Entity/EntityInterface.php) Definition of a persistent object. - [Handler](https://github.com/youlweb/JulLib/blob/master/src/Lib/Entity/Handler/HandlerInterface.php) Set of operations handling the persistence and retrieval of entities. Math ---- [](#math) - [Function](https://github.com/youlweb/JulLib/blob/master/src/Lib/Math/Functions/FunctionInterface.php) An object-oriented container for mathematical functions. The goal of this architecture is to build function stacks. - [Closure function](https://github.com/youlweb/JulLib/blob/master/src/Lib/Math/Functions/ClosureFunction.php)A user-defined function is used to calculate the function output. - [Log](https://github.com/youlweb/JulLib/blob/master/src/Lib/Math/Functions/Log.php)Natural logarithm and log(`base`). - [Softmax](https://github.com/youlweb/JulLib/blob/master/src/Lib/Math/Functions/Softmax.php)The categorical probability distribution of a vector. The softmax function is often implemented at the final layer of an artificial neural network used for classification. - [Vector](https://github.com/youlweb/JulLib/blob/master/src/Lib/Math/Vector/VectorInterface.php) Perform common arithmetic operations on a vector of floats. For instance, the cosine similarity of two vectors is commonly used in text mining and classification tasks. String ------ [](#string) - [Filter](https://github.com/youlweb/JulLib/blob/master/src/Lib/String/Filter/FilterInterface.php) A filter transforms a string. This object-oriented approach allows to build filter stacks. - [Lowercase](https://github.com/youlweb/JulLib/blob/master/src/Lib/String/Filter/Lowercase.php)Convert all alphabetical characters to lowercase. - [Uppercase](https://github.com/youlweb/JulLib/blob/master/src/Lib/String/Filter/Uppercase.php)Convert all alphabetical characters to uppercase. - [Whitespace](https://github.com/youlweb/JulLib/blob/master/src/Lib/String/Filter/Whitespace.php)Trim consecutive whitespaces down to a single whitespace. New lines and tabs are also converted to a single whitespace. - [Property](https://github.com/youlweb/JulLib/blob/master/src/Lib/String/Property/PropertyInterface.php) A property quantifies a particular aspect of a string. Useful to create vector representations, such as word vectors. - [Closure property](https://github.com/youlweb/JulLib/blob/master/src/Lib/String/Property/ClosureProperty.php)A user-defined function is used to calculate the property value. - [Shannon entropy](https://github.com/youlweb/JulLib/blob/master/src/Lib/String/Property/ShannonEntropy.php)Estimate the average minimum number of bits needed to encode a string. One of the many aspects to consider to create strong passwords, or measure randomness in a string. - [Tokenizer](https://github.com/youlweb/JulLib/blob/master/src/Lib/String/Tokenizer/TokenizerInterface.php) Break a string down into an array of terms. - [Delimiter](https://github.com/youlweb/JulLib/blob/master/src/Lib/String/Tokenizer/Delimiter.php)Similar to PHP's native explode() function, with additional checks. - [Repeated substring](https://github.com/youlweb/JulLib/blob/master/src/Lib/String/Tokenizer/RepeatedSubstring.php)Find all repeated substrings in a string. Used in full text indices, data compression, semantic analysis, spam filtering, and within the field of bioinformatics. - [Suffix array](https://github.com/youlweb/JulLib/blob/master/src/Lib/String/Tokenizer/SuffixArray.php)A sorted array of all suffixes of a string. An efficient alternative to a suffix tree. Sys --- [](#sys) - [PhpInfo](https://github.com/youlweb/JulLib/blob/master/src/Lib/Sys/PhpInfo.php) Wrapper for the classic phpinfo() function. ### Health Score 20 — LowBetter than 14% of packages Maintenance20 Infrequent updates — may be unmaintained Popularity5 Limited adoption so far Community6 Small or concentrated contributor base Maturity41 Maturing project, gaining track record Bus Factor1 Top contributor holds 100% of commits — single point of failure How is this calculated?**Maintenance (25%)** — Last commit recency, latest release date, and issue-to-star ratio. Uses a 2-year decay window. **Popularity (30%)** — Total and monthly downloads, GitHub stars, and forks. Logarithmic scaling prevents top-heavy scores. **Community (15%)** — Contributors, dependents, forks, watchers, and maintainers. Measures real ecosystem engagement. **Maturity (30%)** — Project age, version count, PHP version support, and release stability. ### Community Maintainers ![](https://www.gravatar.com/avatar/c60fcc16a965c6acf2e074f8e6beb3f2d1786e5fcbb56702843433affc7ebf1f?d=identicon)[youlweb](/maintainers/youlweb) --- Top Contributors [![youlweb](https://avatars.githubusercontent.com/u/2779672?v=4)](https://github.com/youlweb "youlweb (81 commits)") ### Embed Badge ![Health badge](/badges/jul-lib/health.svg) ``` [![Health](https://phpackages.com/badges/jul-lib/health.svg)](https://phpackages.com/packages/jul-lib) ``` PHPackages © 2026 [Directory](/)[Categories](/categories)[Trending](/trending)[Changelog](/changelog)[Analyze](/analyze)
