Using single quotation mark gives backslash \ character before it

Question

Using code I cant use single quotation marks because it prints 2 backslashes before. So all the code is useless.

Example:

    eval (\'$\'.$a.\'=\'.$b);

Results in:

    eval (\\\'$\\\'.$a.\\\'=\\\'.$b);

 

I am using the markdown plugin, maybe thats the problem ?

How can I fix it ?

Comments

Actually this is happening with single and double quotation marks. My site is a complete mess because of this.

Anyone knows how to fix it ?
