Cannot redeclare radio() error, why?

Question

PHP

I don’t understand why my function does not work, it writes an error

Cannot redeclare radio() (previously declared in C:\OpenServer\domains\hostTraining\frontend\views\test\update.php:6)

When I turn on the function

function radio($answer, $right, $number){
    if ($answer == $right){
        return '<label><input type="radio" name="right" class="radio radio-'.$number.'" value="'.$answer.'" checked><span>Правильный</span></label>';
    } else {
        return '<label><input type="radio" name="right" class="radio radio-'.$number.'" value="'.$answer.'" checked><span>Правильный</span></label>';
    }
}

It's just so much less for me to write than to constantly announce

<?= Html::beginForm(['test/update', 'id' => $model->id], 'post') ?>
    <div>
        <label>Вопрос </label>
        <?= Html::input('text', 'Question', $model->name, ['class' => ['form-control']]) ?>
    </div>
    <div>
        <label>Ответ 1 </label>
        <?php echo Html::input('text', 'Answer[1]', $answer[1], ['class' => 'answer-1']);
        if ($answer[1] == $right){
            echo '<label><input type="radio" name="right" class="radio radio-1" value="'.$answer[1].'" checked><span>Правильный</span></label>';
        } else {
            echo '<label><input type="radio" name="right" class="radio radio-1" value="'.$answer[1].'"><span>Правильный</span></label>';
        }
    </div>
    <div>
        <label>Ответ 2 </label>
        <?php echo Html::input('text', 'Answer[2]', $answer[2], ['class' => 'answer-2']);
        if ($answer[2] == $right){
            echo '<label><input type="radio" name="right" class="radio radio-1" value="'.$answer[2].'" checked><span>Правильный</span></label>';
        } else {
            echo '<label><input type="radio" name="right" class="radio radio-1" value="'.$answer[2].'"><span>Правильный</span></label>';
        }
    </div>
    <div>
        <label>Ответ 3 </label>
        <?php echo Html::input('text', 'Answer[3]', $answer[3], ['class' => 'answer-3']);
        if ($answer[3] == $right){
            echo '<label><input type="radio" name="right" class="radio radio-1" value="'.$answer[3].'" checked><span>Правильный</span></label>';
        } else {
            echo '<label><input type="radio" name="right" class="radio radio-1" value="'.$answer[3].'"><span>Правильный</span></label>';
        }
    </div>
    <div>
        <label>Ответ 4 </label>
        <?php echo Html::input('text', 'Answer[4]', $answer[4], ['class' => 'answer-4']);
        if ($answer[4] == $right){
            echo '<label><input type="radio" name="right" class="radio radio-1" value="'.$answer[4].'" checked><span>Правильный</span></label>';
        } else {
            echo '<label><input type="radio" name="right" class="radio radio-1" value="'.$answer[4].'"><span>Правильный</span></label>';
        }
    </div>
    <?php echo FileInput::widget(['name' => 'attachment[]']) ?>
    <div class="form-group">
        <?= Html::submitButton('Редактировать', ['class' => 'btn btn-primary']); ?>
        <?= Html::a('Удалить', ['test/delete', 'id' => $model->id], ['class' => 'btn btn-danger']) ?>
    </div>
<?= Html::endForm() ?>

Who can say what is the problem?

Answer 1

Cannot redeclare radio() (previously declared in C:\OpenServer\domains\hostTraining\frontend\views\test\update.php:6)

The interpreter tells you that it cannot redefine the function, it is already defined in the update.php file on line 6. And this file is connected to the current one.

Answer 2

The problem is that you already have one function called radio, and you can't just declare a second one with the same name.
And in general, you have noodles there . Do not do it this way.
