<?php var_dump($argv); ?>

ok - run it directly - get what's expected.

$ php /tmp/check-arg.php -s test yellow bus
array(5) {
  [0]=>
  string(18) "/tmp/check-arg.php"
  [1]=>
  string(2) "-s"
  [2]=>
  string(4) "test"
  [3]=>
  string(6) "yellow"
  [4]=>
  string(3) "bus"
}

ok - so I want to run this script as if it were a command (it's a php script that replaces an existing command), so I created this script

$ vi /tmp/testingcommand
php /tmp/check-arg.php $1 $2 $3 $4 $5 $6 $7 $8 $9 $10

so I should be able to just

$ /tmp/testingcommand -s test yellow bus
array(6) {
  [0]=>
  string(18) "/tmp/check-arg.php"
  [1]=>
  string(2) "-s"
  [2]=>
  string(4) "test"
  [3]=>
  string(6) "yellow"
  [4]=>
  string(3) "bus"
  [5]=>
  string(3) "-s0"
}  

OK - so where did that "-s0" come from?  I've done some fiddling and it's what is in $argv[1] (-s) and a "0" (so in this case -s0)

Any ideas? happened on our RHEL7 as well as a Fedora 30 setup

since the script can be run either directly (php program.php) or via a script I can just ignore the last index of argv[]
I guess I could check argv[0] for '...php' and keep all indexs and if no ...php  then ignore last index

Odd

so the problem is with:

php /tmp/check-arg.php $1 $2 $3 $4 $5 $6 $7 $8 $9 $10 

needs to be

php /tmp/check-arg.php $1 $2 $3 $4 $5 $6 $7 $8 $9 $(10)
or
php /tmp/check-arg.php "$@"

At a guess, is it limited to 10 arguments - 0-9? So it thinks $10 is
$1 concat "0" ?

Cheers,

yeah, except instead of $(10) it should be ${10} - both worked though
but the "$@" was the key so if it did go over 10 arguments it wouldn't matter.
