Running PHP Scripts

∟Running PHP Scripts

This section describes how to run PHP scripts in a command window in normal mode and in CGI mode.

PHP scripts can be executed with two different command interfaces:

PHP CLI (Command Line Interface), php.exe - Scripts are executed under the normal operation system environment.
PHP CGI (Common Gateway Interface), php-cgi.exe - Scripts are executed under the CGI environment created by a Web server.

To do a quick test with both interfaces, I wrote the following simple script, hello.php, with a text editor:

Hello <?php echo "world!"; ?>

I used the \local\php\php.exe to execute this script in a command window:

C:\herong> \local\php\php hello.php
Hello world!

Then, I used the \local\php\php-cgi.exe to execute this script in a command window:

>\php\php-cgi Hello.php
X-Powered-By: PHP/7.3.0
Content-type: text/html; charset=UTF-8

Hello world!

PHP CGI, php-cgi.exe, generated the HTTP response header as required by the Web server.

Congratulations, PHP engine is stalled and working!
