what is ?[0;32m and ?[0m in php spark

I suppose those would be color-codes (probably malformed) that your terminal fails to recognize and shows them literally.

An example from the standard Ubuntu Linux .bashrc:

if [ "$color_prompt" = yes ]; then
PS1='${debian_chroot:+($debian_chroot)}\[\033[01;32m\]\u@\h\[\033[00m\]:\[\033[01;34m\]\w\[\033[00m\]\$ '

where 01;32m sets the text color to green. If and when the terminal understands it.
