How can I replace this character | in JavaScript?

<html>
<body>

<script type="text/javascript">

var str="data|data|data";
document.write(str.replace(/|/g,"<br />"));

</script>

In the output of given code, every character has the “< br />”

I don’t know what is wrong with my code.. 🙂

Also, for PHP, I want the function to use if the input is

|string||

and the output should be 

string

only. I want only the outer part of the string in PHP to be subtituted: ||hel||lo|| would become hel||lo.

Could I use trim()? I think trim() only applies to white spaces.

    JavaScript:

    You have to escape the pipe symbol:

    document.write(str.replace(/\|/g,"<br />"));
//                       ---^

    PHP:

    You can pass another parameter to trim() that specifies which characters to remove:

    $str = trim($str, '| ');

    If you also want to remove the character in the middle of the string you can use str_replace():

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