What is the use of argv in php

$argv-an array of parameters passed to the script

An array of strings that holds an array of pointers to your string parameters, each element pointing to a parameter

Description

An array of parameters passed to the current script when running under the command line.

Note:

The first parameter is always the file name of the current script, so $argv [0] is the script file name.

This variable is only available when register_argc_argv is turned on.

Argv- is defined in the $_ SERVER global array (the argv variable is passed to the program's C-style command-line arguments when the script is run on the command line).

Examples are as follows:

When using this command to execute: php script.php arg1 arg2 arg3

The output of the above routine is similar to:

Array (4) {[0] = > string (10) "script.php" [1] = > string (4) "arg1" [2] = > string (4) "arg2" [3] = > string (4) "arg3"} "how to use argv in php" is here. Thank you for reading.
