PHP port of the JavaScript classNames utility. https://github.com/JedWatson/classnames
composer require cjstroud/classnames-php
The classNames can be accessed anywhere.
classNames('foo', ['bar' => true]); // 'foo bar'
The classNames function takes any number of arguments which can be a string or array.
When using an array, if the value associated with a given key is falsy, that key won't be included in the output.
If no value is given the true is assumed.
classNames('foo'); // 'foo'
classNames(['foo' => true]); // 'foo'
classNames('foo', ['bar' => false, 'baz' => true]); // 'foo baz'
classNames(['foo', 'bar' => true]) // 'foo bar'
// Falsy values get ignored
classNames('foo', null, 0, false, 1); // 'foo 1'
Objects and functions will be ignored, unless the object has __toString() function. If it does that will be called and the string value used.
class ExampleObject {
function __toString()
{
return 'bar';
}
}
classNames('foo', function() {}, new stdClass(), new ExampleObject()); // 'foo bar'
<div class="{{ classNames('foo', ['bar' => true]) }}"></div>
<div class="foo bar"></div>
