how to remove new lines inside of php string?

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?

Solution

  • You need to place the \n in double quotes.
    Inside single quotes it is treated as 2 characters '\' followed by 'n'. For consistency, \r is better to be removed too.

    You need:

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