Escape characters

Hi,

I have a strange basic problem but I cant figure out why it doesn't work.

If I put echo( "this\n\r is\n\r a\n\r test\n\r" ); on my page I see no carriage return and line-feeds????

Result: this is a test

Who can help me?

Thanks,
Jack

cause /n line breaks dont work on html, u need <br> to see its effect on a web page.

I have a similar problem, but in a text area.

I have some code, which I want to add into the text box, and then when the user click on the link,the text is displayd already:

$text  = "\r\n\r\n\r\nPage generated by ......";
print "<TEXTAREA NAME=message COLS=40 ROWS=10 CLASS=formElement ID=message>$text</TEXTAREA>";

What this does is, create a text field, with some text already in the textfield, with 3 spaces for the user to type his own message.
This then gets emailed, as an HTML message. The problem is, it doesn't add those spaces into the email, nor any carrage returns, when I hit the enter button inside the textarea.
What do I need todo to convert the \n and \r and carriage returns to <BR>?

In general, PHP's "\n" does nothing for any HTML stuff. HTML strips all the whitespace out (yes, it's very annoying at times). The only purpose for using PHP's "\n" is to make the source code easier to read (and therefore easier to debug). You'll notice that when you look at the source code for the HTML, there will be those 3 returns before any more text.

[edit]I realized that I may have not actually answered the question. The way to turn the \n and \r into <br> is to include the <br> everywhere you include \n. If you're parsing a string that includes newlines, you could do something like

$string = str_replace("\n", "\n<br />", $string);

I had a look at

$text=str_replace ("\r\n", " ", $text);

, which works great in this example. Cause in the textarea there is still 3 spaces, and now in the email it puts a carrage return where needed, thanx
