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.

## Requiring/Loading
|
||
|
||
If you're using Composer to manage dependencies, you can include the following
|
||
in your composer.json file:
|
||
|
||
```json
|
||
{
|
||
"require": {
|
||
"danielstjules/stringy": "~1.9"
|
||
}
|
||
}
|
||
```
|
||
|
||
Then, after running `composer update` or `php composer.phar update`, you can
|
||
load the class using Composer's autoloading:
|
||
|
||
```php
|
||
require 'vendor/autoload.php';
|
||
```
|
||
|
||
Otherwise, you can simply require the file directly:
|
||
|
||
```php
|
||
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.
|
||
|
||
```php
|
||
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:
|
||
|
||
```php
|
||
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:
|
||
|
||
```php
|
||
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:
|
||
|
||
``` php
|
||
$stringy = S::create('Fòô Bàř', 'UTF-8');
|
||
foreach ($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:
|
||
|
||
``` php
|
||
$stringy = S::create('Fòô', 'UTF-8');
|
||
count($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`.
|
||
|
||
``` php
|
||
$stringy = S::create('Bàř', 'UTF-8');
|
||
echo $stringy[2]; // 'ř'
|
||
echo $stringy[-2]; // 'à'
|
||
isset($stringy[-4]); // false
|
||
|
||
$stringy[3]; // OutOfBoundsException
|
||
$stringy[2] = 'a'; // Exception
|
||
```
|
||
|
||
## PHP 5.6 Creation
|
||
|
||
As of PHP 5.6, [`use function`](https://wiki.php.net/rfc/use_function) is
|
||
available for importing functions. Stringy exposes a namespaced function,
|
||
`Stringy\create`, which emits the same behaviour as `Stringy\Stringy::create()`.
|
||
If running PHP 5.6, or another runtime that supports the `use function` syntax,
|
||
you can take advantage of an even simpler API as seen below:
|
||
|
||
``` php
|
||
use function Stringy\create as s;
|
||
|
||
// Instead of: S::create('Fòô Bàř', 'UTF-8')
|
||
s('Fòô Bàř', 'UTF-8')->collapseWhitespace()->swapCase();
|
||
```
|
||
|
||
## Methods
|
||
|
||
In the list below, any static method other than S::create refers to a method in
|
||
`Stringy\StaticStringy`. For all others, they're found in `Stringy\Stringy`.
|
||
Furthermore, all methods that return a Stringy object or string do not modify
|
||
the original. Stringy objects are immutable.
|
||
|
||
*Note: If `$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.
|
||
|
||
```php
|
||
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.
|
||
|
||
```php
|
||
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.
|
||
|
||
```php
|
||
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.
|
||
|
||
```php
|
||
S::create(' Ο συγγραφέας ')->collapseWhitespace();
|
||
S::collapseWhitespace(' Ο συγγραφέας '); // 'Ο συγγραφέας'
|
||
```
|
||
|
||
#### contains
|
||
|
||
$stringy->contains(string $needle [, boolean $caseSensitive = true ])
|
||
|
||
S::contains(string $haystack, string $needle [, boolean $caseSensitive = true [, string $encoding ]])
|
||
|
||
Returns true if the string contains $needle, false otherwise. By default,
|
||
the comparison is case-sensitive, but can be made insensitive
|
||
by setting $caseSensitive to false.
|
||
|
||
```php
|
||
S::create('Ο συγγραφέας είπε', 'UTF-8')->contains('συγγραφέας');
|
||
S::contains('Ο συγγραφέας είπε', 'συγγραφέας', 'UTF-8'); // true
|
||
```
|
||
|
||
#### containsAll
|
||
|
||
$stringy->containsAll(array $needles [, 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.
|
||
|
||
```php
|
||
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.
|
||
|
||
```php
|
||
S::create('Str contains foo')->containsAny(array('foo', 'bar'));
|
||
S::containsAny('Str contains foo', array('foo', 'bar')); // true
|
||
```
|
||
|
||
#### 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.
|
||
|
||
```php
|
||
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.
|
||
|
||
```php
|
||
$stringy = S::create('fòô bàř', 'UTF-8'); // 'fòô bàř'
|
||
```
|
||
|
||
#### dasherize
|
||
|
||
$stringy->dasherize();
|
||
|
||
S::dasherize(string $str [, string $encoding ])
|
||
|
||
Returns a lowercase and trimmed string separated by dashes. Dashes are
|
||
inserted before uppercase characters (with the exception of the first
|
||
character of the string), and in place of spaces as well as underscores.
|
||
|
||
```php
|
||
S::create('TestDCase')->dasherize();
|
||
S::dasherize('TestDCase'); // 'test-d-case'
|
||
```
|
||
|
||
#### 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.
|
||
|
||
```php
|
||
S::create('FÒÔ bàřs', 'UTF-8')->endsWith('àřs', true);
|
||
S::endsWith('FÒÔ bàřs', 'àřs', true, 'UTF-8'); // true
|
||
```

||
|
||
#### ensureLeft
|
||
|
||
$stringy->ensureLeft(string $substring)
|
||
|
||
S::ensureLeft(string $substring [, string $encoding ])
|
||

||
|
||
```php
|
||
S::create('foobar')->ensureLeft('http://');
|
||
S::ensureLeft('foobar', 'http://'); // 'http://foobar'
|
||
```
|
||
|
||
#### ensureRight
|
||
|
||
$stringy->ensureRight(string $substring)
|
||
|
||
S::ensureRight(string $substring [, string $encoding ])
|
||
|
||
Ensures that the string begins with $substring. If it doesn't, it's appended.
|
||
|
||
```php
|
||
S::create('foobar')->ensureRight('.com');
|
||
S::ensureRight('foobar', '.com'); // 'foobar.com'
|
||
```
|
||
|
||
#### first
|
||
|
||
$stringy->first(int $n)
|
||
|
||
S::first(int $n [, string $encoding ])
|
||
|
||

||
|
||
```php
|
||
S::create('fòô bàř', 'UTF-8')->first(3);
|
||
S::first('fòô bàř', 3, 'UTF-8'); // 'fòô'

|
||
|
||
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::regexReplace(string $str, string $pattern, string $replacement [, string $options = 'msr' [, string $encoding ]])
|
||
|
||
Replaces all occurrences of $pattern in $str by $replacement. An alias
|
||
for mb_ereg_replace(). Note that the 'i' option with multibyte patterns
|
||
in mb_ereg_replace() requires PHP 5.4+. This is due to a lack of support
|
||
in the bundled version of Oniguruma in PHP 5.3.
|
||
|

||
$stringy->safeTruncate(int $length [, string $substring = '' ])
|
||
|
||
S::safeTruncate(string $str, int $length [, string $substring = '' [, string $encoding ]])
|
||
|
||
Truncates the string to a given length, while ensuring that it does not
|
||
split words. If $substring is provided, and truncating occurs, the
|
||
string is further truncated so that the substring may be appended without
|
||
exceeding the desired length.
|
||
|
||
```php
|
||
S::create('What are your plans today?')->safeTruncate(22, '...');

|
||
|
||
S::slugify(string $str [, string $replacement = '-' ])
|
||
|
||
Converts the string into an URL slug. This includes replacing non-ASCII
|
||
characters with their closest ASCII equivalents, removing remaining
|
||
non-ASCII and non-alphanumeric characters, and replacing whitespace with
|
||
$replacement. The replacement defaults to a single dash, and the string
|
||
is also converted to lowercase.
|
||
|
||
```php
|
||
S::create('Using strings like fòô bàř')->slugify();

```php
|
||
S::create('FÒÔ bàřs', 'UTF-8')->startsWith('fòô bàř', false);

|
||
|
||
Returns the substring beginning at $start with the specified $length.
|
||
It differs from the mb_substr() function in that providing a $length of
|
||
null will return the rest of the string, rather than an empty string.
|
||
|
||
```php
|
||
S::create('fòô bàř', 'UTF-8')->substr(2, 3);
|
||
