Removing carrage returns

Anon

I'm using DHTML on my site, and I need to remove carrage returns or the javascript returns error. I already use php, so using it to remove carrage returns would be no big deal. I can't figure out how to do this though, so could some one help. This would be a good lesson in expanding my understanding of php.
Thanks

$cleanVar = ereg_replace("\r", "", $dirtyVar);

Since you're not actually using any regular expression matching, it's faster to do this, same concept though...

$cleanVar = str_replace("\r","",$dirtyVar);

I was trying to get this working. Before I jsut used includes, but I didn't think I could use them, so I tried using fopen, which I've never used before, and I think I've created an infinate loop. Any coders have some suggestions

if(!($mainn = fopen($main.inc, "r")))
{
print("Error: $mainn could not be read<br>");
}
while(!feof($mainn))
{
$myline = fgets($mainn, 255);
$cleanVar = str_replace("\r","",$myline);
print($cleanVar);
}
fclose($mainn);

$mainn = fopen($main.inc, \"r\")))

is giving you problems, most likely..
$main.inc? if the file name is in $main, then try fopen(\"$main.inc\", \'r\')

if(!$mainn = fopen(\"$main.inc\", \'r)){
print \'Error: $mainn could not be read<br>\';
}

while(!feof($mainn)){
print str_replace(\"\r\",\'\',fgets($mainn, 255));
}
fclose($mainn);

this should work.

there\'s a file content-dumping function...but this\'ll save you some ram, if it\'s run a lot..

oops, those backslashes shouldn't be there - phpbuilder put them there...sorry

Anon

is that fclose tag correct?
Something has to be wrong becuase when I try and load it the it show's it downloding and says its loaded over 5megs before I quit it, and I KNOW the file isn't that big. Any ideas what could be wrong? Here's a larger section.

if ($main == "") {
include ("home.inc");
}
else if ($main != "") {

if(!($mainn = fopen("$main.inc", "r")))
{
print("Error: $mainn could not be read<br>");
}

while(!feof($mainn))
{
print str_replace("\r",'',fgets($mainn,255));}
fclose("$mainn");
}
