如何从字符串中删除多个空行。我查看了 stackoverflow 上的示例并尝试相应地更改我的代码，但我没有得到正确的答案。

function removeMultipleBlankLines(&$array)
{
  $value = $array;
  $value = preg_replace("/(^[\r\n]*|[\r\n]+)[\s\t]*[\r\n]+/", "\n", $value);

  return $value;
}

  $textarray=array("The red","big","  ","  ","fox","is ready","","","to jump.");

  echo print_r(removeMultipleBlankLines($textarray));
