String

String class

String is a class that turns string into PHP objects. It implements a fluent interface, improving how we manipulate strings, and extends functionality by providing common functions.

Imagine that you need to replace "hello" to "goodbye" and make first letter uppercase. In classic PHP it would like something like this:

$string = 'hello, world';
$string = str_replace('hello', 'goodbye', $string);
$string = ucfirst($string);
echo $string; // Goodbye, world

Using the String class it gets simpler:

$string = 'hello, world';
$string = new String\String($string);
echo $string->replace('hello', 'goodbye')->sentencecase(); // Goodbye, world

OR

$string = 'hello, world';
echo String\String::make($string)->replace('hello', 'goodbye')->sentencecase(); // Goodbye, world

LetterPairSimilarity class

This class can be used to compare string using "Strike a match" algorithm.

$similarity = String\LetterPairSimilarity::compare('Healed', 'Healthy');
echo round($similarity, 2); // 0.55

Requirements

• PHP 5.3 and higher
