我是php新手。我有一个代码文件，我使用多个文本编辑器。我将这些值存储在mysql db中。在另一个页面中，我显示一些字段并应用CRUD操作，如更新和删除。 我在更新数据时遇到问题。每当我更新数据时，我的文本编辑器会在文本末尾增加空白行。 我用
Trim
但它对我不起作用？还有其他方法来解决我的问题吗？
这是我的代码
创建代码。

答案 0 :(得分：1)
尝试
$editor1 = preg_replace('/\s+/', ' ', $editor1);
或者您可以为多个电话创建功能。
function removeExtraSpaces($string)
{
$string= preg_replace('/\s+/', ' ', $string);
return $string;
}
调用此功能
$editor1 = removeExtraSpaces($editor1);
答案 1 :(得分：0)
\?仅删除字符串开头或结尾的额外空格。它不会删除字符串中的额外空格。
如果要处理字符串中的额外空格，请考虑多个空格的preg_replace＆＃34; ＆＃34; *只有一个空白＆＃34; ＆＃34;
trim答案 2 :(得分：0)
像这样使用trim()
$lines = array_filter(explode("\n", trim($_POST['textarea'])));
$text = implode("\n", $lines);
编辑01
$lines = preg_split('/\n+/', trim($_POST['textarea']));
$text = implode("\n", $lines);
