test: Strings
brief: >
Any group of characters beginning with an
alphabetic or numeric character is a string,
unless it belongs to one of the groups below
(such as an Integer or Time).
yaml: |
String
php: |
'String'

test: String characters
brief: >
A string can contain any alphabetic or
numeric character, along with many
punctuation characters, including the
period, dash, space, quotes, exclamation, and
question mark.
yaml: |
- What's Yaml?
- It's for writing data structures in plain text.
- And?
- And what? That's not good enough for you?
- No, I mean, "And what about Yaml?"
- Oh, oh yeah. Uh.. Yaml for Ruby.
php: |
array(
"What's Yaml?",
"It's for writing data structures in plain text.",
"And?",
"And what? That's not good enough for you?",
"No, I mean, \"And what about Yaml?\"",
"Oh, oh yeah. Uh.. Yaml for Ruby."

test: Indicators in Strings
brief: >
Be careful using indicators in strings. In particular,
the comma, colon, and pound sign must be used carefully.
yaml: |
the colon followed by space is an indicator: but is a string:right here
same for the pound sign: here we have it#in a string
the comma can, honestly, be used in most cases: [ but not in, inline collections ]
php: |
array(
'the colon followed by space is an indicator' => 'but is a string:right here',
'same for the pound sign' => 'here we have it#in a string',
'the comma can, honestly, be used in most cases' => array('but not in', 'inline collections')
)
---
test: Forcing Strings
brief: >
Any YAML type can be forced into a string using the
explicit !str method.
yaml: |
date string: !str 2001-08-01
number string: !str 192
php: |
array(
'date string' => '2001-08-01',
'number string' => '192'
)
---
test: Single-quoted Strings
brief: >
You can also enclose your strings within single quotes,
which allows use of slashes, colons, and other indicators
freely. Inside single quotes, you can represent a single
quote in your string by using two single quotes next to
each other.
yaml: |
all my favorite symbols: '#:!/%.)'
a few i hate: '&(*'
why do i hate them?: 'it''s very hard to explain'
entities: '£ me'
php: |
array(
'all my favorite symbols' => '#:!/%.)',
'a few i hate' => '&(*',
'why do i hate them?' => 'it\'s very hard to explain',
'entities' => '£ me'
)
---
test: Double-quoted Strings
brief: >
Enclosing strings in double quotes allows you
to use escapings to represent ASCII and
Unicode characters.
yaml: |
i know where i want my line breaks: "one here\nand another here\n"
php: |
array(
'i know where i want my line breaks' => "one here\nand another here\n"
)
---
test: Multi-line Quoted Strings
todo: true
brief: >
Both single- and double-quoted strings may be
carried on to new lines in your YAML document.
They must be indented a step and indentation
is interpreted as a single space.
yaml: |
i want a long string: "so i'm going to
let it go on and on to other lines
until i end it with a quote."
php: |
array('i want a long string' => "so i'm going to ".
"let it go on and on to other lines ".
"until i end it with a quote."
)
---
test: Plain scalars
todo: true
brief: >
Unquoted strings may also span multiple lines, if they
are free of YAML space indicators and indented.
yaml: |
- My little toe is broken in two places;
- I'm crazy to have skied this way;
- I'm not the craziest he's seen, since there was always the German guy
who skied for 3 hours on a broken shin bone (just below the kneecap);
- Nevertheless, second place is respectable, and he doesn't
recommend going for the record;
- He's going to put my foot in plaster for a month;
- This would impair my skiing ability somewhat for the
duration, as can be imagined.
php: |
array(
"My little toe is broken in two places;",
"I'm crazy to have skied this way;",
"I'm not the craziest he's seen, since there was always ".
"the German guy who skied for 3 hours on a broken shin ".
"bone (just below the kneecap);",
"Nevertheless, second place is respectable, and he doesn't ".
"recommend going for the record;",
"He's going to put my foot in plaster for a month;",
"This would impair my skiing ability somewhat for the duration, ".
"as can be imagined."

---
test: 'Null'
brief: >
You can use the tilde '~' character for a null value.
yaml: |
name: Mr. Show
hosted by: Bob and David
date of next season: ~
php: |
array(
'name' => 'Mr. Show',
'hosted by' => 'Bob and David',
'date of next season' => null
)
---
test: Boolean
brief: >
You can use 'true' and 'false' for Boolean values.
yaml: |
Is Gus a Liar?: true
Do I rely on Gus for Sustenance?: false
php: |
array(
'Is Gus a Liar?' => true,
'Do I rely on Gus for Sustenance?' => false
)
---
test: Integers
dump_skip: true
brief: >
An integer is a series of numbers, optionally
starting with a positive or negative sign. Integers
may also contain commas for readability.
yaml: |
zero: 0
simple: 12
one-thousand: 1,000
negative one-thousand: -1,000
php: |
array(
'zero' => 0,
'simple' => 12,
'one-thousand' => 1000.0,
'negative one-thousand' => -1000.0
)
---
test: Integers as Map Keys
brief: >
An integer can be used a dictionary key.
yaml: |
1: one
2: two
3: three
php: |
array(
1 => 'one',
2 => 'two',
3 => 'three'
)
---
test: Floats
dump_skip: true
brief: >
Floats are represented by numbers with decimals,
allowing for scientific notation, as well as
positive and negative infinity and "not a number."
yaml: |
a simple float: 2.00
larger float: 1,000.09
scientific notation: 1.00009e+3
php: |
array(
'a simple float' => 2.0,
'larger float' => 1000.09,
'scientific notation' => 1000.09
)
---
test: Time
todo: true
brief: >
You can represent timestamps by using
ISO8601 format, or a variation which
allows spaces between the date, time and
time zone.
yaml: |
iso8601: 2001-12-14t21:59:43.10-05:00
space separated: 2001-12-14 21:59:43.10 -05:00
php: |
array(
'iso8601' => mktime( 2001, 12, 14, 21, 59, 43, 0.10, "-05:00" ),
'space separated' => mktime( 2001, 12, 14, 21, 59, 43, 0.10, "-05:00" )
)
---
test: Date
todo: true
brief: >
A date can be represented by its year,
month and day in ISO8601 order.
yaml: |
1976-07-31
php: |
date( 1976, 7, 31 )
