Just another variant of previous script that group arguments doesn't starts with '-' or '--'
<?php
function arguments($argv) {
 $_ARG = array();
 foreach ($argv as $arg) {
 if (ereg('--([^=]+)=(.*)',$arg,$reg)) {
 $_ARG[$reg[1]] = $reg[2];
 } elseif(ereg('^-([a-zA-Z0-9])',$arg,$reg)) {
 $_ARG[$reg[1]] = 'true';
 } else {
 $_ARG['input'][]=$arg;
 }
 }
 return $_ARG;
}
print_r(arguments($argv));
?>
