PHP-回声要求在变量中传递代码

Question

I have some sudo code here

    $image_position = left

    switch($image_position){
        case 'left':
            $block_con = "require(locate_template('templates/block-media-left.php'))";
            break;
        case 'right':
            $block_con = 'require(locate_template("templates/block-media-right.php"))';
            break;
        case 'center':
            $block_con = 'require(locate_template("templates/block-media-center.php"))';
            break;  
        default:
            $block_con = 'require(locate_template("templates/block-text.php"))';

    }


    <div>

        <?php echo $block_con; ?>

    </div>

Depending on the value of the $image_position I want to load a different block of php found in a templates folder.

The switch works but echo a string and does not add the require code.

I didn't think it would but don't know how to do this.

How about this?

<?php 
$image_position = 'left';
switch($image_position){
    case 'left':
        $block_con = 'templates/block-media-left.php';
        break;
    case 'right':
        $block_con = 'templates/block-media-right.php';
        break;
    case 'center':
        $block_con = 'templates/block-media-center.php';
        break;  
    default:
        $block_con = 'templates/block-text.php';
}
?>


<div>
    <?php require(locate_template($block_con)); ?>
</div>

It's important to note that this is just REQUIRING the PHP file currently. This means it'll be included and executed. You'd have to echo in that included PHP file to get any output.
