eregi_replace not replacing \r\n

[deleted]

I have a form which after submission reports the entered values. One of the values is multiline text (mediumtext). I am using eregi_replace to replace the carriage breaks (\r\n in this case) with in the formatted results.

The code is below:
<?php
$workout = mysql_escape_string($_POST['newworkoutdesc']);

// changes carriage returns into line breaks
$workoutdescription = eregi_replace("\r\n"," ",$workout);

echo $workoutdescription;
?>

The Output:
4-5 x 1 Mile at 1/2 marathon effort\r\n8 x 200 strides\r\n\r\n40 seconds rest after the miles.\r\n

The odd thing is that I am using pretty much the same code elsewhere and it works. The main difference is that the value for the code that works is being pulled from a database.

I could use some help with this one.

Thanks.

Try to use

$workoutdescription = eregi_replace("\r\n"," ",$workout);

Backslashes must be escaped by another \

dunno if this helps, but i've never used eregi_replace before so i know nothing about it. What I use though is str_replace:



$workout = mysql_escape_string($_POST['newworkoutdesc']); 

// changes carriage returns into line breaks 
$workoutdescription = str_replace("\n", "<br>", $workout); 

echo $workoutdescription;

but then thats just me 🙂

You should use str_replace() it is much faster than using regular expressions.

I tried using
$workout = $row['workoutdesc'];

// changes carriage returns into line breaks
$workoutdescription = str_replace("\n", " ", $workout);

echo $workoutdescription;

and
$workoutdescription = str_replace("\r\n", " ", $workout);

but I am still getting the same output.

the function nl2br might do what you are trying for also. it changes newlines to 's in a given string of text as a variable or a literal.

example:
$text = "hello\nThis is an\n example of the nl2br\nfunction";
$brtext = nl2br($text);

echo $brtext;
/
:::outputs:::
hello 
This is an 
example of the nl2br 
function
/

as far as I know, nl2br() only replaces \n, not \r or \r\n

If your server is on windows (\r\n) or macintosh (\r), then use str_replace()

if I run the following code:

<?
$text = "4-5 x 1 Mile at 1/2 marathon effort\r\n8 x 200 strides\r\n\r\n40 seconds rest after the miles.\r\n";

$newtext = nl2br($text);

echo $newtext;
?>

the output in html is exactly:
4-5 x 1 Mile at 1/2 marathon effort 
8 x 200 strides 
 
40 seconds rest after the miles.

so nl2br will work with \r\n
all a carriage return is, is an operation that prepares for the next character to be printed as the first character on a line. the newline or \n is what actually does the break

ah, I didn't test it. I just read a user submitted comment on the nl2br() page at php.net ( http://www.php.net/nl2br() ) The one by eightraks at linux-foo dot com

He suggested using ereg_replace to replace either of the 3 instances: \n, \r, \r\n, so I figured since this was on the nl2br() page, it would only work convernt \n's.

Anyways, good to know. I should've tested before posting.
