I'm trying to make a LaTeX parser in PHP, and I want to remove certain trailing new lines (\\
signs).
But the problem is, I only want to remove the new line (the double backslash) if it's before everything else.
Like, I want to remove the first \\
in the following example:
\\3+6=9
But not this \\
:
3+\\6=9
How can I do this with PHP?
