如何从字符串中移除换行符并用一个空格替换? PHP
假设以下带换行符的字符串
$sentence = " My name is John Smith My Favorite subject is PHP. ";
你需要移除上述换行符并替换为空格,即输出应为 -
My name is John Smith My Favourite subject is PHP.
为此,使用 trim() 和 preg_replace() 进行替换。
示例
PHP 代码如下
<!DOCTYPE html> <html> <body> <?php $sentence = " My name is John Smith My Favorite subject is PHP. "; $sentence = trim(preg_replace('/\s\s+/', ' ', $sentence)); echo $sentence; ?> </body> </html>
输出
这将产生如下输出
My name is John Smith My Favorite subject is PHP.
