Hi crimso,

...and to limit how big the post got.
This is very appreciated indeed.

First of all. There are functions and libs for everything. Command-Line-Option Parsing may be done with getopt: Look here: PHP: getopt - Manual

(But you may ignore that, if your code works).

The following does not work:

Code:
<?php 
#!/usr/bin/php -q

If you decide to use #!, it has to be at the very beginning of the Script-File. Only then the kernel will read the following binary as interpreter for the actual file.

Further without testing the code myself, I suggest you test, if your Arg-parsing produces correct output. I suspect it may not fully work as expected and the values are not what you assume them to be. I suggest you insert some debug statements before+after Arg parsing like:

Code:
print_r($parms);
print_r($arg);
print_r($value);
print_r($host);
print(gettype($host));

A logging function would help you to debug your code independently of the running environment(webserver or command line).

Code:
#!/usr/bin/php
<?PHP
# global log-file handle
$log = NULL;
function mylog($msg=NULL) {
       $logfile="/tmp/myapp.log";  # There may be better locations than /tmp for the logfile
       global $log;
       if(!$log) {   
            # only open logfile once per script run. After the first
            # mylog() invocation the open filehandle will be used.
            # Also be lazy and let it automatically be closed at 
            # end of programm by php itself
          $log = fopen($logfile,"a");
          if(! $log) die("Cannot open Logfile: " . error_get_last());
       }
       if($msg) {
                fwrite($log,date("Y/m/d h:i:s",mktime())." : ".getmypid()." : ".(string)$msg."\n");
       }
}

The above mentioned debug statements are easily usable with such a log function(print_r needs to be told, that it returns the formated dump data and so it does not print it to stdout itself).

Code:
mylog(print_r($host,true));

PHP: Hypertext Preprocessor

PHP.net is a great and fabulous source of documentation for PHP. Nearly all functions documentation pages have directly attached real-life coding examples down at the bottom of each page.

php_ini_scanned_files

PHP_INI_SCANNED_FILES(3)						 1						  PHP_INI_SCANNED_FILES(3)

php_ini_scanned_files - Return a list of .ini files parsed from the additional ini dir

SYNOPSIS

       string php_ini_scanned_files (void  )

DESCRIPTION

       php_ini_scanned_files(3)  returns  a comma-separated list of configuration files parsed after php.ini. These files are found in a directory
       defined by the --with-config-file-scan-dir option which is set during compilation.

	The returned configuration files also include the path as declared in the --with-config-file-scan-dir option.

RETURN VALUES

	Returns a comma-separated string of .ini files on success. Each comma is followed by a newline. If the directive  --with-config-file-scan-
       dir wasn't set, FALSE is returned. If it was set and the directory was empty, an empty string is returned. If a file is unrecognizable, the
       file will still make it into the returned string but a PHP error will also result. This PHP error will be seen both  at	compile  time  and
       while using php_ini_scanned_files(3).

EXAMPLES

       Example #1

	      A simple example to list the returned ini files

	      <?php
	      if ($filelist = php_ini_scanned_files()) {
		  if (strlen($filelist) > 0) {
		      $files = explode(',', $filelist);

		      foreach ($files as $file) {
			  echo "<li>" . trim($file) . "</li>
";
		      }
		  }
	      }
	      ?>
