PHP Installation Problem

Hi, I need help installing PHP on a Linux Red Hat 7 I downloaded the tar.gz distribution, decompressed, and put: ./configure, but i forgot the options, so i press control+c to stop the process, write the line to put ./configure --options...... and hit enter, the scripts says that only one configuration can be at time or something like this, and i can't restart the process, tried to continue with install (Make | Make install), but it doesn't work, also removed the directory and decompressed php again, and it doesn't work :( Any idea on how i can reset the configure status? thanks!!!
