问题描述

如何使用PHP或regex修剪每行新行的开头和结尾的空格?

How do you trim white space on beginning and the end of each new line with PHP or regex?

例如，

$text = "similique sunt in culpa qui officia 

     deserunt mollitia animi, id est 

  laborum et dolorum fuga   

";

应该是

$text = "similique sunt in culpa qui officia

deserunt mollitia animi, id est

laborum et dolorum fuga
";

推荐答案

使用正则表达式无疑可以更快地完成此任务.但是，如果您喜欢嵌套函数，那么这也将在所有行中 trim 空格:

Using a regex is certainly quicker for this task. But if you like nesting functions this would also trim whitespace from all lines:

$text = join("\n", array_map("trim", explode("\n", $text)));
