Behaviour¶

To know what a behaviour is, read the chapter “Behaviours”.

Behaviour example: lower case¶

<?php
namespace Romm\Formz\Behaviours;

/**
 * Transforms a value in lowercase.
 *
 * @see \Romm\Formz\Behaviours\AbstractBehaviour
 */
class ToLowerCaseBehaviour extends AbstractBehaviour {
    /**
     * @inheritdoc
     */
    public function applyBehaviour($value)
    {
        if (is_array($value)) {
            foreach ($value as $key => $val) {
                $value[$key] = $this->applyBehaviour($val);
            }
        }
        else {
            $value = $this->applyBehaviourInternal($value);
        }

        return $value;
    }

    /**
     * Transforms the given value in lower case.
     *
     * @param  mixed    $value    The value.
     * @return string
     */
    protected function applyBehaviourInternal($value)
    {
        return mb_strtolower($value, 'UTF-8');
    }
}
