How to run the PHP CLI script

The first method is to use php-f / path/to/yourfile.php. Invoke the PHP CLI interpreter and pass parameters to the script. The first step of this method is to set the path of the php interpreter. Before running CLI, the Windows platform needs to set a command similar to path c:\ php, which also loses the meaning of the first line of the CLI script, so this method is not recommended.

The second way is to first run chmod+x (UNIX/Linux environment), make the PHP file executable, then add a declaration on the first line of the CLI script header (similar to the #! / usr/bin/php or PHP CLI interpreter location), and then execute it directly on the command line. This is the preferred method for CLI and is recommended
