+
+## Why?
+Env aims to bring a unified parser for env together for PHP rather than having a few incomplete or buggy parsers written 
+into other libraries. This library is not meant as a complete package for config loading like other libraries as this 
+is out of scope for this library. If you need something like that check out [Vars](http://github.com/m1/Vars) which incorporates
+this library so you can load Env and other file types if you want, or checkout [PHP Dotenv](https://github.com/josegonzalez/php-dotenv)
+if you only need .env parsing
+
+## Requirements
+
+Env requires PHP version `5.3+` - supported and tested on `5.3`, `5.4`, `5.5`, `5.6`, `7` and `hhvm`.
+
+## Install
+
+Via Composer
+
+``` bash
+$ composer require m1/env
+```
+
+## Usage
+
+### Basic
+
+test.env
+```bash
+TEST_1 = VALUE
+```
+
+example.php
+```php
+<?php
+
+//both examples return the same thing
+
+// example 1 -- standard
+use M1\Env\Parser;
+
+$env = new Parser(file_get_contents('test.env'));
+$arr = $env->getContent();
+
+// example 2 -- statically
+$arr = Parser::parse(file_get_contents('test.env'));
+
+var_dump($arr);
+// [
+//      "TEST_1" => "VALUE"
+// ]
+```
+### Context variables
+
+test_context.env
+```bash
+TEST_1 = $EXTERNAL
+TEST_2 = VALUE
+```
+
+example_context.php
+```php
+<?php
+
+//both examples return the same thing
+
+// example 1 -- standard
+use M1\Env\Parser;
+
+$env = new Parser(file_get_contents('test_context.env'), array('EXTERNAL' => 'external'));
+$arr = $env->getContent();
+
+// example 2 -- statically
+$arr = Parser::parse(file_get_contents('test_context.env'), array('EXTERNAL' => 'external'));
+
+var_dump($arr);
+// [
+//      "TEST_1" => "external"
+//      "TEST_2" => "VALUE"
+// ]
+```
+
+### Syntax
+
+The Syntax is slightly more relaxed than bash, but still remains quite bash like
+
+#### Assignment
+To assign values the syntax is `key = value`, unlike bash the assignment is pretty relaxed, any of the below are valid:
+```bash
+TEST1 = value
+TEST2= VALUE
+TEST3 =VALUE
+TEST4=VALUE
+ TEST5 = VALUE
+TEST6  =   VALUE
+```
+
+However keys can not start with a number, e.g.:
+
+```bash
+1notvalid = nope
+```
+
+Will throw a `ParseException`
+
+You can also add `export` to the start of variables to `source` the file in bash ([see here](#source) for more info):
+
+```bash
+export TEST1=value
+```
+
+#### Strings
+
+Strings can either be in quotes (single or double) or without:
+
+```bash
+TEST1 = value
+TEST2 = "value"
+TEST3 = 'value'
+```
+
+To escape new lines or quotes is the standard backslash:
+
+```bash
+TEST1 = "value \n value"
+TEST2 = "value \"value\" value"
+TEST3 = 'value \' value \' value'
+```
+
+If you feature two quoted strings as a value then only the first quoted string will be assigned to the key:
+
+```bash
+TEST1 = "value value" "this sentence in quotes will not be counted"
+```
+
+#### Numbers
+
+Numbers are fairly standard:
+```bash
+TEST1 = 1
+TEST2 = 2
+```
+
+Decimal numbers will be automatically cast to floats:
+```bash
+TEST1 = 1.1 # `float` type
+TEST2 = 2   # `int` type
+```
+
+If you quote numbers they will be counted as strings, or if you have two numbers on one line:
+```bash
+TEST1 = 33 33 # `string` type
+TEST2 = "22"  # `string` type
+```
+
+#### Booleans
+
+Booleans can be `true`, `false`, `yes` and `no`:
+```bash
+TEST1 = true
+TEST2 = false
+TEST3 = yes
+TEST4 = no
+```
+
+Booleans are case-insensitive:
+```bash
+TEST1 = True
+TEST2 = False
+TEST3 = YES
+TEST4 = NO
+```
+
+Booleans in quotes will be treated as strings:
+```bash
+TEST1 = "true" # `string` type
+TEST2 = "YES"  # `string` type
+TEST3 = 'NO'   # `string` type
+```
+
+#### Null
+
+Both of the below are counted as null values:
+```bash
+TEST1 =
+TEST2 = null
+```
+
+Whereas an empty string is counted as a string:
+```bash
+TEST1 = "" # `string` type
+TEST2 = '' # `string` type
+```
+
+#### Variables
+
+Variables are based of the bash syntax:
+```bash
+TEST1 = 'hello'
+TEST2 = ${TEST27} # 'hello'
+```
+
+The types of variable get passed to the calling variable if there is only one variable. If there are more than one variable,
+the calling variable is automatically cast to a string:
+```bash
+TEST1 = 1 # `int` type
+TEST2 = 2 # `int` type
+TEST3 = ${TEST1} ${TEST2} # `string` type
+TEST4 = true     # `bool` type
+TEST5 = ${TEST4} # `bool` type
+```
+
+Also if the variable is in quotes then the variable will be automatically cast as a string:
+```bash
+TEST1 = 1 # `int` type
+TEST2 = "${TEST1}" # `string` type
+```
+
+But you can use variables without quotes and they'll be cast as strings:
+```bash
+TEST1 = foo
+TEST2 = bar
+TEST3 = ${TEST1}/${TEST2} # `string` type
+```
+
+Variables are useful to use in strings like so:
+```bash
+TEST1 = "foo"
+TEST2 = 'bar'
+TEST3 = "hello ${TEST1} and ${TEST2}"
+```
+
+Null values are passed and casted as empty strings if in quotes:
+```bash
+TEST1 = null
+TEST2 = ${TEST1} # `null` type
+TEST3 = "${TEST1}" # `string` type
+```
+
+Single Quotes with variables will be counted as strings:
+```bash
+TEST1 = '${hello} # `string` type, will output: '${hello}'
+```
+
+
+##### Parameter Expansion
+
+You can do parameter expansion, so far you can only do [default values](http://wiki.bash-hackers.org/syntax/pe#use_a_default_value) 
+and [assign default values](http://wiki.bash-hackers.org/syntax/pe#assign_a_default_value) like in the bash syntax:
+
+```bash
+TEST1 = foo
+TEST2 = ${TEST3:=bar}
+TEST4 = ${TEST5=bar}
+TEST6 = ${TEST7:-bar}
+TEST8 = ${TEST9-bar}
+```
+
+The default value parameter expansion syntax is `:-`, the explanation on the [bash-hackers wiki](http://wiki.bash-hackers.org/syntax/pe#use_a_default_value) for this is:
+> SYNTAX:
+>
+>`${PARAMETER:-WORD}`
+>
+>`${PARAMETER-WORD}`
+>
+>If the parameter PARAMETER is unset (never was defined) or null (empty), this one expands to WORD, otherwise it 
+>expands to the value of PARAMETER, as if it just was ${PARAMETER}. If you omit the : (colon), like shown in the second 
+>form, the default value is only used when the parameter was unset, not when it was empty.
+
+For example:
+```bash
+TEST1 = foo
+TEST2 = ${TEST1:-bar} # TEST1 is set so the value of TEST2 = foo
+
+TEST3 = ${TEST4:-bar} # TEST4 is not set so the value of TEST3 = bar
+
+TEST5 = null
+TEST6 = ${TEST5-bar} # TEST5 is set but empty so the value of TEST6 = null
+TEST7 = ${TEST6:-bar} # TEST5 is set and empty so the value of TEST7 = bar
+
+```
+
+The assign default value parameter expansion is `:=`, the explanation on the [bash-hackers wiki](http://wiki.bash-hackers.org/syntax/pe#assign_a_default_value) for this is:
+> SYNTAX:
+>
+>`${PARAMETER:=WORD}`
+>
+>`${PARAMETER=WORD}`
+>
+>This one works like the using default values, but the default text you give is not only expanded, but also assigned 
+>to the parameter, if it was unset or null. Equivalent to using a default value, when you omit the : (colon), as 
+>shown in the second form, the default value will only be assigned when the parameter was unset.
+
+For example:
+```bash
+TEST1 = foo
+TEST2 = ${TEST1:=bar} # TEST1 is set so the value of TEST2 = foo
+
+TEST3 = ${TEST4:=bar} # TEST4 is not set so the value of TEST3 = bar and TEST4 = bar
+
+TEST5 = null
+TEST6 = ${TEST5=bar} # TEST5 is set but emtpy so the value of TEST6 = null 
+TEST7 = ${TEST6=bar} # TEST5 is set and empty so the value of TEST7 = bar and TEST5 = bar
+```
+#### Comments
+
+To comment, just use the `#` syntax, you can also comment inline like so:
+```bash
+# This is a comment
+TEST1 = bar # and so is this
+```
+
+If you put a `#` without a space in a unquoted string, it will be parsed as a string:
+
+```bash
+TEST1 = hello#notacomment
+```
+
+### .env example
+
+```bash
+# Comments are done like this
+
+# Standard key=value
+TEST1 = value
+TEST2 = value
+TEST3 = value # You can also comment inline like this
+
+# Strings
+TEST4 = "value"
+
+## The value of the below variable will be TK4 = "value value"
+TEST5 = "value value" "this sentence in quotes will not be counted"
+
+## Escape newline
+TEST6 = "value \n value"
+
+## Escape double quotes
+TEST7 = "value \"value\" value"
+
+## You can also exchange any of the above for single quotes, eg:
+TEST8 = 'value'
+TEST9 = 'value \' value \' value'
+
+# Numbers
+TEST10 = 1
+TEST11 = 1.1
+TEST12 = 33 33 # Will output as a `string` -- not a number as two numbers are given
+TEST13 = "33" # 33 -- `string` type
+
+# Bools -- All of the below are valid booleans
+TEST14 = true
+TEST15 = false
+TEST16 = yes
+TEST17 = no
+
+## Booleans are case-insensitive
+TEST18 = True
+TEST19 = False
+TEST20 = YES
+TEST21 = NO
+
+TEST22 = "true" # "true" -- `string` type
+TEST23 = "YES" # "YES" -- `string` type
+TEST24 = 'NO' # "NO" -- `string` type
+
+# Null values
+TEST25 =
+TEST26 = null
+
+# Variables
+TEST27 = 'hello'
+TEST28 = ${TEST27} # 'hello'
+
+TEST29 = 1
+TEST30 = 2
+TEST31 = ${TEST29}   # 1 -- `int` type
+TEST32 = "${TEST29}" # 1 -- `string` type
+TEST33 = ${TEST29} ${TEST30} # 1 2 -- `string` type
+
+TEST34 = foo
+TEST35 = bar
+TEST36 = ${TEST34}/${TEST35} # foo/bar -- `string` type
+
+TEST37 = "foo"
+TEST38 = 'bar'
+TEST39 = "hello ${TEST37} and ${TEST38}" # hello foo and bar -- `string` type
+
+TEST40 = true
+TEST41 = false
+TEST42 = ${TEST40} # true -- `bool` type
+TEST43 = ${TEST40} ${TEST41} # true false -- `string` type
+
+TEST44 = null
+TEST45 = ${TEST44} # null -- `null` type
+TEST46 = "${TEST44}" # '' -- `string` type
+TEST46_5 = '${TEST44}' # '' -- `string` type
+
+TEST47=foo
+TEST48=${TEST47:=bar}
+TEST49=${TEST50:=foo}
+TEST51=${TEST52:-foo}
+TEST53=null
+TEST54=${TEST53=foo}
+TEST55=null
+TEST56=${TEST55-foo}
+TEST57=${TEST58:=""}
+TEST59=${TEST60:=null} # TEST59 = null TEST60 = null -- both `null` types
+TEST61=${TEST62:=true} # TEST61 = true TEST62 = true -- both `bool` types
+
+# Comments
+TEST63 = hello # comment
+TEST64 = "hello # comment"
+TEST65 = "hello" #comment
+TEST66 = #comment
+TEST67 = "#comment"
+TEST68 = thisisnota#comment
+```
+
+The result from this library and the expected result of the above is:
+
+```php
+array(
+    "TEST1" => "value",
+    "TEST2" => "value",
+    "TEST3" => "value",
+    "TEST4" => "value",

+    "TEST6" => "value \n value",
+    "TEST7" => 'value "value" value',

+);
+```
+## Notes
+
+### Source
+
+If you need the .env variables in other applications, you can `source` the env, but make sure it's valid bash syntax, as this parser allows a more relaxed form of bash syntax.
+
+```bash
+source .env
+```
+
+This library will always be able to parse bash syntax, but for now the opposite (env syntax -> bash syntax) may not be true, however this is being worked on to bring a strict parser version for `3.0`
+
+## Other library comparisons
+
+The difference between this library and other similar libraries:
+
+#### `zrcing/phpenv`: 
+- Converts all value types to string
+- Does not support `null` values
+- Does not support `int`, `float` or `bool` types
+- Does not support variables
+
+#### `Dotenv\Dotenv`:
+- Does not support unquoted values like `33 33`, this should be cast to string. See `TEST12`
+- Does not support concatenation of variables unquoted like `${VAR} ${VAR2}`, this should be cast to string. See `TEST33`
+- Both of the above crash `Dotenv` without a helpful exception
+- Converts all value types to string
+- Does not support `null` values
+- Does not support `int`, `float` or `bool` types
+- Does not support variables
+- Does not support [parameter expansions](#parameter-expansion)
+- Does not support inline comments where there is no value. See `TEST66`
+
