Php Var Parser

Get the value of PHP variable and constant

Only regex are used to parse the data, so it can give false result (excpecialy with complex string)

Parse the code content, searching for the provided variables, using regex.
Variables should be in the form: { var1: 'type', var2: 'type'}
Where type is one of: 'number', 'string', 'boolean', 'array', 'array_assoc', 'definedConstant', 'constant', 'variable'.
Note that constant means that t the variable searched is assigned a constant (Eg. $var = CONSTANT)
To search for a constant, use 'definedConstant' (Eg. define('CONSTANT', 'value'))
If no type is provided the parser will try to guess the type, but is slow and dangerous
If provided the suffix will be added to the variable name, remember to double escape special characters (Eg. "\\$")
For arrays, only work with square brackets arrays syntax, not with array() syntax.
The intended use is only for parsing simple configuration file, where you now how the code you are parsing should look like. No check are done on the ouput!

Do not use this library in a production environment!

Given this code:

$myVar = 1;
$foo = 'bar';
$bar = true;
$foo->bar = 'Hello "word"!';
$foo->baz = 'Hi, \'word\'';
$baz = $foo;
define('FOO', 123);
const BAR = 456;
$arr = [1,2,"3"];
$arr_assoc = [1 => 1, 2 => 2, 3 => "3"];

will output like this:

import PhpVarParser from 'PhpVarParser';
PhpVarParser.parse(php, {'myVar': 'number'})
// { myVar: '1' }
PhpVarParser.parse(php, {'foo': 'string'})
// { foo: 'bar' }
PhpVarParser.parse(php, {'bar': 'boolean'})
// { bar: 'true' }
PhpVarParser.parse(php, {'FOO': 'definedConstant'}, '')
// { FOO: '123' }
PhpVarParser.parse(php, {'BAR': 'number'}, 'const ')
// { BAR: '456' }
PhpVarParser.parse(php, {'foo->bar': 'string'})
// { 'foo->bar': 'Hello "word"!' }
PhpVarParser.parse(php, {'bar':'string', 'baz':'string'}, '\\$foo->')
// { bar: 'Hello "word"!', baz: "Hi, \\'word\\'" }
PhpVarParser.parse(php, {'baz':'variable', 'foo':'string'}, '\\$', true)
// { baz: 'bar', foo: 'bar' }
PhpVarParser.parse(php, {'arr': 'array'})
// { arr: [1,2,"3"] }
PhpVarParser.parse(php, {'arr_assoc': 'array_assoc'})
// { arr_assoc: {"1": 1, "2": 2, "3": "3"} }
