[UPHPU] recursively set directories and files different permissions

[Wade Preston Shearer]

Is there a way to recursively set all directories permissions to one  
thing and all files to another?

The reason that I ask is because I have a directory (and everything  
within it) on a website where non-script files (images, style sheets,  
PDFs, etc) are located and I want to ensure that a script file (PHP)  
cannot be placed in there and executed.

I tried removing execution from everything but have discovered that I  
then cannot cd into them. So, it appears that I need all of the  
directories to have execution, but not the files. Don't files inherit  
permissions from their parent directories though? So any new files  
would get execution permissions and my work would be for naught? How  
do people get around this?
