Features

strongly typed
no exceptions thrown
fast
new functions

A fast string manipulation library with multi-byte support. Inspired by the "Stringy" library, with focus on speed.

Lib uses php7 features and does not throw any exceptions (because all input parameters are strongly typed). The code is completely covered by unit tests.

$str = new Str('Acme');
echo (string)$str->slice(2);
// me

Parameters:

int $start
int|null $end

Return:

\Str

slugify

Converts the string into an URL slug.

echo (string)$str->stripWhitespace();
// Acmefoo

// "I see..."

Parameters: nothing

Return:

\Str

titleize

Returns a trimmed string with the first letter of each word capitalized. Also accepts an array, $ignore, allowing you to list words not to be capitalized.

// I Like to Watch Dvds at Home

Parameters:

array $ignore

Return:

\Str

toAscii

Returns an ASCII version of the string. A set of non-ASCII characters are replaced with their closest ASCII counterparts, and the rest are removed by default. The $language or locale of the source string can be supplied for language-specific transliteration in any of the following formats: en, en_GB, or en-GB. For example, passing "de" results in "äöü" mapping to "aeoeue" rather than "aou" as in other languages.

$str = new Str('Äcmế');
echo (string)$str->toAscii();
// Acme

Parameters:

string $language
bool $removeUnsupported
