how to get rid of \r\n\ ??

[karimali831]

Hello,

 

When I post content to database and query from database \r\n\ is suppose to be new line indent so if I posted this:

 

test

test

 

hello

 

I will get: test\r\ntest\r\n\r\nhello\r\nhello

 

How to fix this?

 

Thanks for any help.

From the PHP Manual (but slightly modified):

 

<?php
// Order of replacement
$str     = "Line 1\nLine 2\rLine 3\r\nLine 4\n";
$order   = array("\r\n", "\n", "\r");
$replace = '';

// Processes \r\n's first so they aren't converted twice.
$newstr = str_replace($order, $replace, $str);
?>

 

That is removing them completely from the string. Instead, if you need to display them as new lines, you can use the nl2br() function, that will convert linebreaks to an HTML break (<br />).

 

<?php
$text = "test\r\ntest\r\n\r\nhello\r\nhello";
echo nl2br($text);
?>

 

Your question wasn't quite clear as to remove linebreaks or show them correctly, so I gave both versions.

You could also just use trim to remove the new line characters. Although I think  nl2br is what he is actually looking for.

@tomfmason, doesn't trim() just remove them in the beginning or end of a string? The OP's string had linebreaks in the middle...
