php-serialized v1.2.0

PHP serialize and unserialize for NodeJS (with useful error messages)

const {serialize, unserialize} = require('php-serialized');

serialize([ null ]);
// => 'a:1:{i:0;N;}'

unserialize('a:1:{i:0;N;}');
// => [ [0, null] ]

The return value of unserialize is always an array.

By default, array nodes are not converted in any way.

Pass a function to transform parsed arrays.

unserialize('a:1:{i:0;N;}', (arr) => {
  let res = [];
  for (let i = 0; i < arr.length; i += 2) {
    res[arr[i]] = arr[i + 1];
  }
  return res;
});
// => [ [null] ]

Note: Serialized class instances are not currently supported. Pull requests are encouraged!

parse(str: string, raw: Function | true): Array<Node>

Parse a serialized string into an array of AST nodes.

Any syntax errors are returned in an array. The parser will continue until the end is reached or a fatal error is encountered. This means multiple errors can be returned.

When 1+ errors are encountered, the returned array will only contain error nodes. Use results[0].type !== 'error' to know if there are no errors.

const {parse} = require('php-serialized-ast');

parse('a:0:{}');
// => [{ type: 'array', value: [], start: 0, end: 6 }]

parse('a:0:{');
// => [{ type: 'error', error: 'Array never closed', start: 0 }]

reduce(ast: Array<Node> | Node) : any

Convert AST nodes to their raw values using the reduce function.

Array nodes are not converted in any way.

const {reduce, parse} = require('php-serialized-ast');

reduce(parse('a:1:{i:0;N;}')); => [ [0, null] ]

Note: Doing reduce(parse(str)) will always be slower than doing unserialize(str) because of the intermediate AST nodes.
