I have a textarea that i get via $_POST in php. I want to replace the carriage returns in the string, but it won't work. I tried $var=str_replace("\n", "",$var); but it didn't work. Also, $var=str_replace("\n", "a",$var); will put an a in between the carriage returns, but it does not get rid of them. Any ideas?

try nl2br() or just swap \n with <br />

It didn't work; it replaced the line break with <br /> but i'm writing them to a file and it kept the line breaks but printed <br /> in them.
Example:
test<br />
<br />
test
