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
. Thearray_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 thearray_shift()
function removes it and returns the remaining arguments.
