simple ereg_replace question

[johnn]

Hi,
For some reasons I don't know, when I display $text, I still have \n and \n\n on screen. I addslashes when inserting to database and stripslashes $text before the statements below, then displaying it. What's wrong with ereg_replace?

// Strip out carriage returns
$text = ereg_replace("\r","",$text);
// Handle paragraphs
$text = ereg_replace("\n\n","<P>",$text);
// Handle line breaks
$joketext = ereg_replace("\n","<BR>",$text);

Uh.. builtin function called nl2br which adds a <br> tag for each new line found is probably want you want to use.

$text = nl2br($text);

Beats me, I'd just use nl2br(): http://php.net/nl2br

Do what was mentioned earlier.

But a side note: if you're doing a simple search and replace (with no regular expressions involved) use str_replace() instead of ereg_replace().

Thanks. If in a form, I enter (type exactly letter by letter) the following 2 sentences:

This is a \n first sentence
This is a second sentence

Note that at the end of the first sentence, I press "enter key" and then type the second sentence.

Say $text contains the 2 sentences above, and then I press submit key to call x.php

<?
echo $text;
$text = nl2br($text);
echo $text;
?>

The first echo displays:
This is a \n first sentence This is a second sentence

The second echo displays:
This is a \n first sentence
This is a second sentence

nl2br works but it won't take care of \n that I typed in the first sentence (a slash and a letter n). How do I turn the first sentence into:

This is a
first sentence

Thanks,
John

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

Typing \n in a form isn't the same as \n in PHP. \n in a form is actually \\n (two separate characters).

[johnn]

$text = str_replace("\\n","<br />",$text);
Typing \n in a form isn't the same as \n in PHP. \n in a form is actually \\n (two separate characters).

Thanks. It works. I don't why the form does that to \n (adding another slash)?

BTW Why do we need "/" in <br /> ? I saw in some other threads have it too. But with or without it, it still works.

Thanks,
John

Its the new xhtml way of writing <br>, I guess it will become the standard in the future, so everyone is getting their code ready.
