That is not correct. In JavaScript, it will only replace the first occurrence of `|`, you *have* to use regular expressions here.

i want only the outer part of the string in php to be subtituted.. like "||hel||lo||" and the output would be "hel||lo"

@vrynxzent: You can use `trim()` for this, see my answer.

Answer 3

+2 A:

you need to escape the | character because it is used as OR in regex /a|b/ matches either a OR b. Try /\|/

Edit: To achieve wour last goal try doing it this way (alot of regex,I know):

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

Answer 4

+3 A:

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);
