Dear Experts,

I don't know why when I pass variable into php script on command line
that doesn't work, for example, the following test.php code. Nothing
is echo out.

php test.php 1 2 3 5

#!/usr/bin/php
<?php

echo $argv[1]."\n";
echo $argv[2]."\n';
var_dump($argc);

?>
I am using  php version as follows
 
PHP 5.3.21 (cli) (built: Feb  4 2013 12:36:43)
Copyright (c) 1997-2013 The PHP Group
Zend Engine v2.3.0, Copyright (c) 1998-2013 Zend Technologies
    with eAccelerator v0.9.6.1, Copyright (c) 2004-2010 eAccelerator, by eAccelerator
    with the ionCube PHP Loader v4.2.2, Copyright (c) 2002-2012, by ionCube Ltd., and
    with Zend Guard Loader v3.3, Copyright (c) 1998-2010, by Zend Technologies

I also try php -f test.php 1 2 3 4  but it also fail.

Do I need to add some option or setting in php.ini before doing passing variable
on command line into php script ? Or is it related to the type of console shell I am
using ? I am using BASH linux shell on apache linux server and I am through my home computer  putty software connecting to remoter server.

Please advise

from the technical refernce:
http://www.php.net/manual/en/reserved.variables.argv.php
   Note: This variable is not available when register_argc_argv is disabled.  
so, please check you php.ini file:
http://www.php.net/manual/en/ini.core.php#ini.register-argc-argv

realpath_cache_ttl      120      120
register_argc_argv      On      On
register_globals      Off      Off
register_long_arrays      On      On



register_argc_argv is ON from phpinfo() in php but still not working

does:
$_SERVER[ "argv" ]
contain some data?

yes,  it is array with those variable value including "test.php"  ,1,2,3.

Probably I can use $_SERVER instead of $argv for solving the issue

But why the variable  is saved at $_SERVER, supposed it is used on Web browser
not on command shell php running  ?

it is same and NOT working using php-cli  with $argv , and $_server is working
with both

If you have time, I am appreciated you can explain it between $argv  and $_server['argv']

Have a nice day

if the code was in a class module, you would need to declare the variable
global $argv;
first before using it, but other than that, I don't see why it isn't filled.

Thanks for your reply

For my memo only:
1-Temporarily use $_server instead of $argv to solve the issue for continuing project
2- follow up the $argv on command line issue on next new thread later on.
