Step by Step solution about How to resolve the algorithm Command-line arguments step by step in the PHP programming language

This code is written in PHP and it is a simple script that takes command line arguments and stores them in variables.

The first line of the code assigns the name of the program to the variable $program_name.

The second line of the code assigns the second argument passed to the program to the variable $second_arg.

The third line of the code assigns all the arguments passed to the program, except for the program name, to the variable $all_args_without_program_name.

Here is a more detailed explanation of each line of code:

  • $program_name = $argv[0];: This line assigns the name of the program to the variable $program_name. The $argv variable is an array that contains all the arguments passed to the program. The first element of this array is the name of the program.
  • $second_arg = $argv[2];: This line assigns the second argument passed to the program to the variable $second_arg. The second element of the $argv array is the second argument passed to the program.
  • $all_args_without_program_name = array_shift($argv);: This line assigns all the arguments passed to the program, except for the program name, to the variable $all_args_without_program_name. The array_shift() function removes the first element of an array and returns it. In this case, the first element of the $argv array is the program name, so the array_shift() function removes it and returns the remaining arguments.

<?php
$program_name = $argv[0];
$second_arg = $argv[2];
$all_args_without_program_name = array_shift($argv);
