But I create a test files called test.php, with te famous Hello Worl inside. I install PHP 4.0.4 with every tool that I foun, and manualy too, but it doesen't work. Except for one issue, if I include in the first line this: #!/php/php It work's, but show me , in the browser, the first line, if I erase it I get the error 500. I didn't what if wrong, if it's something in Apache or in PHP. Thank's and sorry for my english, I'm Argentinian, and I spoke in Spanish. Best Regards
