Stripping line breaks from a string - ereg_replace & str_replace

I have a problem with a script in that the script saved line breaks between values that were saved. Well, the script was written that way for another purpose but now it is causing me issues...

I know I can take normal text like this and remove the /n's

$myvalues = 'cars/ntrucks/nautomibiles';

Using code like this:

$myvalues = ereg_replace('/n', '', $myvalues);

HOWEVER, I do not know how to remove LINE BREAKS which I assume would be \n in the data?

For example:

PHP Code:


		
			
<?php

$myvalues = 'cars

trucks

automibiles';

echo $myvalues . '<br />';



$myvalues = ereg_replace('/n', '', $myvalues);

echo $myvalues . '<br />';

?>

Outputs the data like this (HTML CODE):

Quote:

cars
trucks
automibiles<br />cars
trucks
automibiles<br />

Can someone help be strip these line breaks out of my string?

EDIT to change the title to help someone else that may search this!

It's \n and not /n... (backslash). And it should go between double quotes.

Well, I am closer but the darned line break remains in the code :confused:

I have also been trying to do the same thing with "str_replace" so I used that in my test code too.

Here is my test code:

PHP Code:


		
			
<?php

$myvalues = 'cars

trucks

automobiles';

echo 'DATA IN<br />';

echo nl2br($myvalues) . '<br />';





echo '<br />TEST 1<br />';

$test1= ereg_replace("\n", 'YEA', $myvalues);

echo nl2br($test1) . '<br />';



echo '<br />TEST 2<br />';

$test2 = str_replace("\n", "GO", $myvalues);

echo nl2br($test2) . '<br />';

?>

Here is the output:

Quote:

DATA IN
cars
trucks
automobiles

TEST 1
cars
YEAtrucks
YEAautomobiles

TEST 2
cars
GOtrucks
GOautomobiles

Perhaps I am going about this wrong? I just want to kill those nastly little line breaks :erm:

Remove the "carriage return" characters as well.

PHP Code:


		
			
$test1= ereg_replace("[\r\n]+", 'YEA', $myvalues);

Thank You, that was the problem!

My Test Code:

PHP Code:


		
			
<?php

$myvalues = 'cars

trucks

automobiles';

echo 'DATA IN<br />';

echo nl2br($myvalues) . '<br />';





echo '<br />TEST 2<br />';

$test2 = str_replace("\n", "GO", $myvalues);

echo nl2br($test2) . '<br />';



echo '<br />TEST 3<br />';

$test3= str_replace("\r\n", "NO", $myvalues);

echo nl2br($test3) . '<br />';



echo '<br />TEST 4<br />';

$test4 = str_replace("\r\n", "", $myvalues);

echo nl2br($test4) . '<br />';



?>

OUTPUT:

Quote:

TEST 2

TEST 3

TEST 4

That is exactly what I needed! This is the second time you saved me, I really appreciate your help!

You should use the Perl functions (preg) for regex rather than the PHP ones (ereg).
