Stringy

A PHP string manipulation library with multibyte support. Offers both OO method chaining and a procedural-style static wrapper. Tested and compatible with PHP 5.3+ and HHVM. Inspired by underscore.string.js.

Build Status

Requiring/Loading

If you're using Composer to manage dependencies, you can include the following in your composer.json file:

{
    "require": {
        "danielstjules/stringy": "~1.8"
    }
}

Then, after running composer update or php composer.phar update, you can load the class using Composer's autoloading:

require 'vendor/autoload.php';

Otherwise, you can simply require the file directly:

require_once 'path/to/Stringy/src/Stringy.php';
// or
require_once 'path/to/Stringy/src/StaticStringy.php';

And in either case, I'd suggest using an alias.

use Stringy\Stringy as S;
// or
use Stringy\StaticStringy as S;

OO and Procedural

The library offers both OO method chaining with Stringy\Stringy, as well as procedural-style static method calls with Stringy\StaticStringy. An example of the former is the following:

use Stringy\Stringy as S;
echo S::create('Fòô     Bàř', 'UTF-8')->collapseWhitespace()->swapCase();  // 'fÒÔ bÀŘ'

Stringy\Stringy has a __toString() method, which returns the current string when the object is used in a string context, ie: (string) S::create('foo') // 'foo'

Using the static wrapper, an alternative is the following:

use Stringy\StaticStringy as S;
$string = S::collapseWhitespace('Fòô     Bàř', 'UTF-8');
echo S::swapCase($string, 'UTF-8');  // 'fÒÔ bÀŘ'

Implemented Interfaces

Stringy\Stringy implements the IteratorAggregate interface, meaning that foreach can be used with an instance of the class:

$stringy = S::create('Fòô Bàř', 'UTF-8');
foreach ($stringy as $char) {
    echo $char;
}
// 'Fòô Bàř'

It implements the Countable interface, enabling the use of count() to retrieve the number of characters in the string:

$stringy = S::create('Fòô', 'UTF-8');
count($stringy);  // 3

Furthermore, the ArrayAccess interface has been implemented. As a result, isset() can be used to check if a character at a specific index exists. And since Stringy\Stringy is immutable, any call to offsetSet or offsetUnset will throw an exception. offsetGet has been implemented, however, and accepts both positive and negative indexes. Invalid indexes result in an OutOfBoundsException.

$stringy = S::create('Bàř', 'UTF-8');
echo $stringy[2];     // 'ř'
echo $stringy[-2];    // 'à'
isset($stringy[-4]);  // false

$stringy[3];          // OutOfBoundsException
$stringy[2] = 'a';    // Exception

PHP 5.6 Creation

As of PHP 5.6, use function is available for importing functions. Stringy exposes a namespaced function, Stringy\create, which emits the same behaviour as Stringy\Stringy::create(). If running PHP 5.6, or another runtime that supports the use function syntax, you can take advantage of an even simpler API as seen below:

use function Stringy\create as s;

// Instead of: S::create('Fòô     Bàř', 'UTF-8')
s('Fòô     Bàř', 'UTF-8')->collapseWhitespace()->swapCase();

Methods

In the list below, any static method other than S::create refers to a method in Stringy\StaticStringy. For all others, they're found in Stringy\Stringy. Furthermore, all methods that return a Stringy object or string do not modify the original. Stringy objects are immutable.

Note: If $encoding is not given, it defaults to mb_internal_encoding().

at

$stringy->at(int $index)

S::at(int $index [, string $encoding ])

Returns the character at $index, with indexes starting at 0.

S::create('fòô bàř', 'UTF-8')->at(6);
S::at('fòô bàř', 6, 'UTF-8');  // 'ř'

camelize

$stringy->camelize();

S::camelize(string $str [, string $encoding ])

Returns a camelCase version of the string. Trims surrounding spaces, capitalizes letters following digits, spaces, dashes and underscores, and removes spaces, dashes, as well as underscores.

S::create('Camel-Case')->camelize();
S::camelize('Camel-Case');  // 'camelCase'

chars

$stringy->chars();

S::chars(string $str [, string $encoding ])

Returns an array consisting of the characters in the string.

S::create('Fòô Bàř', 'UTF-8')->chars();
S::chars('Fòô Bàř', 'UTF-8');  // array(F', 'ò', 'ô', ' ', 'B', 'à', 'ř')

collapseWhitespace

$stringy->collapseWhitespace()

S::collapseWhitespace(string $str [, string $encoding ])

Trims the string and replaces consecutive whitespace characters with a single space. This includes tabs and newline characters, as well as multibyte whitespace such as the thin space and ideographic space.

S::create('   Ο     συγγραφέας  ')->collapseWhitespace();
S::collapseWhitespace('   Ο     συγγραφέας  ');  // 'Ο συγγραφέας'

contains

$stringy->contains(string $needle [, boolean $caseSensitive = true ])

S::containsAll(string $haystack, array $needles [, boolean $caseSensitive = true [, string $encoding ]])

Returns true if the string contains all $needles, false otherwise. By default the comparison is case-sensitive, but can be made insensitive by setting $caseSensitive to false.

S::create('Str contains foo and bar')->containsAll(array('foo', 'bar'));
S::containsAll('Str contains foo and bar', array('foo', 'bar'));  // true

containsAny

$stringy->containsAny(array $needles [, boolean $caseSensitive = true ])

S::containsAny(string $haystack, array $needles [, boolean $caseSensitive = true [, string $encoding ]])

Returns true if the string contains any $needles, false otherwise. By default the comparison is case-sensitive, but can be made insensitive by setting $caseSensitive to false.

countSubstr

$stringy->countSubstr(string $substring [, boolean $caseSensitive = true ])

S::countSubstr(string $str, string $substring [, boolean $caseSensitive = true [, string $encoding ]])

Returns the number of occurrences of $substring in the given string. By default, the comparison is case-sensitive, but can be made insensitive by setting $caseSensitive to false.

S::create('Ο συγγραφέας είπε', 'UTF-8')->countSubstr('α');
S::countSubstr('Ο συγγραφέας είπε', 'α', 'UTF-8');  // 2

create

S::create(mixed $str, [, $encoding ])

Creates a Stringy object and assigns both str and encoding properties the supplied values. $str is cast to a string prior to assignment, and if $encoding is not specified, it defaults to mb_internal_encoding(). It then returns the initialized object. Throws an InvalidArgumentException if the first argument is an array or object without a __toString method.

$stringy = S::create('fòô bàř', 'UTF-8');  // 'fòô bàř'

dasherize

$stringy->dasherize();

endsWith

$stringy->endsWith(string $substring [, boolean $caseSensitive = true ])

S::endsWith(string $str, string $substring [, boolean $caseSensitive = true [, string $encoding ]])

Returns true if the string ends with $substring, false otherwise. By default, the comparison is case-sensitive, but can be made insensitive by setting $caseSensitive to false.

S::create('FÒÔ bàřs', 'UTF-8')->endsWith('àřs', true);
S::endsWith('FÒÔ bàřs', 'àřs', true, 'UTF-8');  // true

ensureLeft

S::pad(string $str , int $length [, string $padStr = ' ' [, string $padType = 'right' [, string $encoding ]]])

Pads the string to a given length with $padStr. If length is less than or equal to the length of the string, no padding takes places. The default string used for padding is a space, and the default type (one of 'left', 'right', 'both') is 'right'. Throws an InvalidArgumentException if $padType isn't one of those 3 values.

S::create('fòô bàř', 'UTF-8')->pad( 10, '¬ø', 'left');

The replacement defaults to a single dash, and the string is also converted to lowercase.

S::create('Using strings like fòô bàř')->slugify();
S::slugify('Using strings like fòô bàř');  // 'using-strings-like-foo-bar'

startsWith

$stringy->startsWith(string $substring [, boolean $caseSensitive = true ])

S::startsWith(string $str, string $substring [, boolean $caseSensitive = true [, string $encoding ]])

Returns true if the string begins with $substring, false otherwise. By default, the comparison is case-sensitive, but can be made insensitive by setting $caseSensitive to false.

tidy

$stringy->tidy()

S::tidy(string $str)

Returns a string with smart quotes, ellipsis characters, and dashes from Windows-1252 (commonly used in Word documents) replaced by their ASCII equivalents.

S::create('“I see…”')->tidy();
S::tidy('“I see…”');  // '"I see..."'

titleize

$stringy->titleize([ string $encoding ])

S::titleize(string $str [, array $ignore [, string $encoding ]])

Returns a trimmed string with the first letter of each word capitalized. Ignores the case of other letters, preserving any acronyms. Also accepts an array, $ignore, allowing you to list words not to be capitalized.

$ignore = array('at', 'by', 'for', 'in', 'of', 'on', 'out', 'to', 'the');
S::create('i like to watch DVDs at home', 'UTF-8')->titleize($ignore);

toTabs

$stringy->toTabs([ tabLength = 4 ])

S::toTabs(string $str, [, int $tabLength = 4 ])

Converts each occurrence of some consecutive number of spaces, as defined by $tabLength, to a tab. By default, each 4 consecutive spaces are converted to a tab.

S::truncate('What are your plans today?', 19, '...');  // 'What are your pl...'

underscored

$stringy->underscored();

S::underscored(string $str [, string $encoding ])
