我认为这对你有用:

function read($file) {
  ob_start();
  include($file);
  $content = ob_get_contents();
  ob_end_clean();

  return $content;
}

像这样使用它:

$file = 'path/to/your/file.php';
$content = read($file);

要传递变量,您可以修改上面的函数,如下所示:

  function read($file, $vars) {
    ob_start();
    extract($vars, EXTR_SKIP);
    include($file);
    $content = ob_get_contents();
    ob_end_clean();

    return $content;
  }

  $file = 'path/to/your/file.php';
  $vars = array(
    'var1' => 'value',
  );
  $content = read($file, $vars);

您可以像这样访问包含文件中的变量:print $ var1;
