php-clj

This is a fork of php-clj that has been updated for compatibility with newer versions of the ordered dependency. The tests have been updated to pass in Clojure 1.10.1. If you are getting an error like clojure.lang.ExceptionInfo: Conflicting data-reader mapping {:url #object[java.net.URL 0x42039326 "jar:file:/home/john/.m2/repository/org/flatland/ordered/1.5.7/ordered-1.5.7.jar!/data_readers.clj"], :conflict ordered/set, :mappings {ordered/set #'ordered.set/into-ordered-set, ordered/map #'ordered.map/ordered-map}} with the mainline php-clj, then this fork is what you need.

A Clojure library to deserialize PHP as generated by serialize into Clojure data structures and vice versa.

Current version: 0.5.1

Supported Clojure versions: 1.10.1

Usage

(ns foo.bar
  (:require [php_clj.core :refer [php->clj clj->php]]))

(php->clj "s:18:\"Café Scientifique\";")
;; => "Café Scientifique"

(php->clj "i:1337;")
;; => 1337

(php->clj "a:2:{s:4:\"Wöo\";a:3:{i:0;i:1;i:1;i:2;i:2;i:3;}s:3:\"Bar\";b:0;}")
;; => #ordered/map (["Wöo" [1 2 3]] ["Bar" false])

(clj->php "Café")
;; => "s:5:\"Café\";"

(clj->php {"name" "Bob"})
;; => "a:1:{s:4:\"name\";s:3:\"Bob\";}"

A Note on PHP Arrays

As PHP's Arrays are actually ordered maps, converting an array such as:

array(
    "name" => "Bob",
    "age" => 42
)

Will result in an ordered map equivalent to the following:

{"name" "Bob", "age" 42}

Note that Clojure's standard map implementation does not retain insertion order (and ArrayMaps are only suitable for "very small maps") hence the use of the ordered-map type.

Arrays with consecutive indices starting at 0 such as

array(
    0 => "a",
    1 => "b",
    2 => "c"
)

Will be converted into vectors like so:

["a" "b" "c"]

Installation

php-clj is available on Clojars, add the following to your Leiningen dependencies:
