Php.ini file missing

Hi, I am new to this list and also to php and I am sorry to already bother you with a question you might find really stupid, but I looked around for this information several days now and I couldn't find some good resources. I installed php 4.1.0 on Mac OS X 10.1.2 and everything seems to work well, also with mySQL and Apache. I am learning php from a book for beginners full of explanations and scripts, so in the last days I wrote some scripts which make possible to send e-mails filling a form on the browser. The scripts worked out well, but I haven't been able to read the e-mails and understand where I should be able to. I believed I had to change the SMTP settings of php or some sort of mail server in the system and reading some articles found in several web sites I think the solution would be to change some settings in the "php.ini" file. The build I downloaded doesn't have any "php.ini" file and in the faq section of the website from where I downloaded it (http://www.entropy.ch/software/macosx/php/) there is simply written to create the "php.ini" file in the "/usr/local/lib/php.ini", including the intermediate /lib/ directory that doesn't exist already on my system. I would like to know how I can create the "php.ini" file or if there is a easier way to get and read the e-mails sent by the php scripts without working on the php configuration. I am sorry to disturb you all, but I don't have any experience and I haven't been able to find anything clear about this question. I would really appreciate if you could give me some tips or some web site's addresses where I can find easy information, or where I can download a copy of the "php.ini" file. I thank you in advance for the kindness and the attention. Greetings, Michael
