替换PHP中的空行 [英] replace blank lines in php

问题描述

如何从字符串中删除多个空白行. 我查看了关于stackoverflow的示例，并尝试相应地更改了代码，但是我没有得到正确的答案.

How do I remove multiple blank lines from a string. I have looked at the examples on stackoverflow and have tried to change my code accordingly but I am not getting the right answer.

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));

推荐答案

您可以这样做:

$array_with_nonblank_lines = array_filter($textarray, 'trim');

获得您想要的东西.

此处是 php的有关trim函数的文档页面的链接，该页面做这项工作.

Here is link to php's docs page about trim function, which does the job.
