带换行符的str_replace？ [关闭]

Question

I'm trying to replace a regular expression with a line break. Right now I'm trying this which doesn't work:

$string = str_replace(';', '
', $string);

I need to make sure that semi colons are exactly the same as ' ' line breaks, how can I get this done?

Use double quotes, otherwise is not parsed. Documentation
