UnderscoreNamingStrategy

Zend\Stdlib\Hydrator\NamingStrategy\UnderscoreNamingStrategy Converts snake case strings (e.g. foo_bar_baz) to studly case strings (e.g. fooBarBaz) and vice versa.

Example Usage

<?php
$namingStrategy = new \Zend\Stdlib\Hydrator\NamingStrategy\UnderscoreNamingStrategy();
echo $namingStrategy->extract('foo_bar'); // outputs: foo_bar
echo $namingStrategy->extract('Foo_Bar'); // outputs: foo_bar
echo $namingStrategy->extract('FooBar'); // outputs: foo_bar

echo $namingStrategy->hydrate('fooBar'); // outputs: fooBar
echo $namingStrategy->hydrate('FooBar'); // outputs: fooBar
echo $namingStrategy->hydrate('Foo_Bar'); // outputs: fooBar
?>

This strategy can be used in hydrators to dictate how keys should be mapped.

<?php
class Foo {
    public $fooBar;
}

$hydrator = new \Zend\Stdlib\Hydrator\ObjectProperty();
$hydrator->setNamingStrategy(new \Zend\Stdlib\Hydrator\NamingStrategy\UnderscoreNamingStrategy());

$foo = new Foo();
$hydrator->hydrate(['foo_bar' => 123],$foo);

print_r($foo); // Foo Object ( [fooBar] => 123 )
print_r($hydrator->extract($foo)); // Array ( [foo_bar] => 123 )
?>
