Advanced PHP for Web Professionals

phpinfo( )

phpinfo() is a very useful function that allows you to see what version of PHP is running on your Web server, as well as all of the specific settings that are enabled in that version.

Throughout this book, there are sections that ask you to verify your settings. One way to do this is to create a script that includes just the following:

<? 
    phpinfo();
?>

Upon execution of the script, the browser displays the current PHP settings. This function is especially useful if you are working on somebody else's server and are not quite sure of its capabilities.
