PHP Removing Windows ^M Character

Question

I have a CSV I am downloading from a source I'm not in control of and the end of each line is a

^M 

character when printed to a bash terminal. How can I sanitize this input programmatically in PHP?

Answer 1

What you're seeing is a Windows control character. To get rid of this in PHP, what you need to do is $file = str_ireplace("\x0D", "", $file) this will work whether hexadecimal is lowercase or uppercase.

Answer 2

You can also ask PHP to auto detect any weird line endings by just adding in this line before reading the CSV file and you won't be required to do anything else.

ini_set('auto_detect_line_endings', true);

Answer 3

^M is a carriage return, you should be able to remove it with:

$string = str_replace( "\r", "", $string);
