Avoid PHP errors

This reverts commit 910308a2e7de472138261fca8f14b363e409a243.

Finally found out that using a back slash will allow us to use the $ in a bash script.

These settings cause PHP to throw an error. Bash can't echo "$conf" because bash isent that smart. I tried to fix this using printf and cat but could not get the result we need. For now this should be removed until someone can fix it.
