Line break problems in PHP filter textarea

The replacement code I wrote earlier is like this.

$content = Str_replace ('\ r \ n', $_post['content') );

To ensure that window and Linux line breaks are removed, change to this:

$content = Str_replace ('\ r'= str_replace ('\ n  ", $content);

Run the time to find that there is still a problem, the newline is not replaced, and then began to Baidu textarea line break, and the use of str_replace, and finally found to be single quotation marks and double quotes using the problem.

Finally, change to:

$content = Str_replace ("\ r \ n""", $_post['content'  = Str_replace ("\r""" = Str_replace ("\ n"" ", $content);

Filtering success
