Check if an IPv4 Address is Inside a CIDR Range

Anonymous

Jun 14, 2026

Splits a CIDR into network and prefix, converts the test IP and network to integers via ip2long, builds a mask as -1 shifted left by 32 minus the prefix, and compares the masked values. Prefix zero matches everything; invalid input throws.

Relative Time Ago Formatter

Anonymous

Takes a DateTimeInterface and returns a string like 3 hours ago by diffing against now in seconds and matching the largest fitting unit from year down to second, with pluralization. Future and sub-second diffs are explicit cases.

Sparkline from Numbers Using Unicode Blocks

Anonymous

Jun 14, 2026

Maps a numeric series onto eight block characters by normalizing each value into the min..max range and scaling to an index 0..7. A flat series (zero range) renders the lowest block. Produces a compact inline chart you can print in a terminal or log line.

Weighted Random Selection

Anonymous

Jun 14, 2026

Picks a key with probability proportional to its integer weight. Sums the weights, draws an int in 1..total, then walks the cumulative weight until it meets or exceeds the draw and returns that key. Runs in one pass with no allocation beyond the inputs.

Bloom Filter in Pure PHP

Anonymous

Jun 14, 2026

Probabilistic set: hashes each item with crc32 plus a sha256-derived second hash, setting bits at h1 + i*h2 mod size for i hashes. mightContain returns false if any bit is unset (definitely absent), true otherwise (probably present). No false negatives.

Base62 Encoder for Short IDs

Anonymous

Jun 4, 2026

Encodes a non-negative integer to a compact base-62 string over 0-9a-zA-Z by repeated modulo and integer division, prepending digits. Decodes by scanning each char back through strpos on the alphabet. Good for short URL-safe slugs.

JSON Pointer (RFC 6901) Resolver

Anonymous

Jun 4, 2026

Walks a decoded JSON document by a slash-delimited pointer, unescaping ~1 to slash and ~0 to tilde in that order per the RFC, descending arrays by key and objects by property. Empty pointer returns the document, a missing segment throws.

Topological Sort with Kahn Algorithm

Anonymous

Jun 4, 2026

Builds an adjacency list and indegree map from a node-to-prerequisites graph, seeds a queue with zero-indegree nodes, then pops each, appends it, and decrements dependents. If fewer nodes come out than went in, a cycle exists.

LRU Cache in Pure PHP Using Ordered Arrays

Anonymous

Jun 4, 2026

Exploits PHP array insertion order: get() unsets and reappends the key so the most recently used sits at the tail, put() evicts via array_shift which drops the least recently used head when over capacity. Effectively O(1) amortized.

Human-Readable Byte Formatter and Parser

Anonymous

Jun 4, 2026

formatBytes derives the unit via floor(log(bytes,1024)), clamps to the unit table, and rounds value/1024^pow. parseBytes reverses it with a regex capturing the number and optional KB to PB suffix, then multiplies by 1024^index.

UUID v7 Generator (Time-Ordered) in Pure PHP

Anonymous

Jun 4, 2026

Builds a UUIDv7 by packing a 48-bit millisecond Unix timestamp into the first 12 hex chars, then 74 random bits from random_bytes, masking the version nibble to 7 and the variant bits to binary 10. Time-ordered so it indexes well as a primary key.

Finite State Machine (FSM) in Pure PHP

Anonymous

May 16, 2026

Stores current state and a transitions map keyed by [from_state][event]. trigger() looks up the next state, moves to it, appends to history, and fires the registered callback. on() accepts an array of source states for multi-origin transitions.
