how to remove new lines and returns from php string?

Question

A php variable contains the following string:

<p>text</p> <p>text2</p> <ul> <li>item1</li> <li>item2</li> </ul> 

I want to remove all the new line characters in this string so the string will look like this:

<p>text</p><p>text2><ul><li>item1</li><li>item2</li></ul> 

I've tried the following without success:

str_replace('\n', '', $str); str_replace('\r', '', $str); str_replace('\r\n\', '', $str); 

Anyone knows how to fix this?

Answer 1

You need to place the \n in double quotes.
Inside single quotes it is treated as 2 characters '\' followed by 'n'

You need:

$str = str_replace("\n", '', $str); 

A better alternative is to use PHP_EOL as:

$str = str_replace(PHP_EOL, '', $str);
