PHP5 Error Message

[Gerard Seibert]

I seem to be having a problem with PHP5. Running the following command 
produces some rather strange output.

$ php -v
PHP Warning:  Module 'mysql' already loaded in Unknown on line 0
PHP Warning:  Module 'pcre' already loaded in Unknown on line 0
PHP Warning:  Module 'bz2' already loaded in Unknown on line 0
PHP Warning:  Module 'gd' already loaded in Unknown on line 0

nknown on line 0

It never produced this output before. What could be causing it and how do 
I correct it?
