When the user opens the php page, the server executes the PHP command and sends the execution results to the user's browser. This is similar to ASP and CoildFusion. PHP can run on WINDOWS and multiple versions of UNIX superior. In addition to being able to manipulate your pages, PHP can also send HTTP headers. You can set cookies, manage digital signatures and redirect users, and it provides excellent connectivity to other databases (also ODBC), integrating various external libraries to do anything from parsing XML with PDF documents. Then did you know that you can use the powerful functions of php to do other things? When running in independent cgi mode, a php executable program is required. It has many command line parameters, some of which can be used for fun purposes. The following are all php command line parameters, where [] indicates that they are optional. Yes, the <> table is a must. Usage php [-q] [-h] [-s] [-v] [-i] [-f ] | { [args...]} -q Quiet mode. Do not output HTTP headers. -s Convert PHP program files to HTML in color format (for example, reserved words are in green, functions and variables are in blue, comments are in yellow and strings are in red, etc. -f reads and interprets the specified file. -c reads the php.ini file in -a run interactively -d foo[=bar] defines the value of the input item foo in ini as bar -e output additional information for debugging and performance analysis -z Load Zend expansion file -i php related information -h help itself. 1. Use php -q filename.php to use the php program as a shell program, 2. Use -s to html your own php program. Isn’t this very worry-free? 3. Use the odbc function of php to operate the database in shell commands.
