Pardon me but what's the big deal?
Put a shebang up top and then add:
//
// ----------------------------------------------------------
// Get CLI args from argv
// ----------------------------------------------------------
//
function getargs($argv)
{
// ./cli.php file1 file2 --path=/foo/bar -t -B quux
// getargs($GLOBALS['argv'])
$args['self'] = array_shift( $argv ) ;
while( 0 < sizeof( $argv ) ) {
$arg = array_shift( $argv ) ;
if( '--' == substr( $arg , 0 , 2 ) ) {
$eq = strpos( $arg , '=' ) ;
$name = substr( $arg , 2 , $eq - 2 ) ;
$val = substr( $arg , $eq + 1 ) ;
$args[$name][] = $val ;
} else if( '-' == $arg[0] ) {
$name = substr( $arg , 1 ) ;
if (isset($argv[0][0]) && ( '-' != $argv[0][0] )) {
$val = array_shift( $argv ) ;
} else {
$val = '' ;
}
$args[$name][] = $val ;
} else {
$args['file'][] = substr( $arg , 0 ) ;
}
}
return $args ;
}
// ----------------------------------------------------------
// Main
// ----------------------------------------------------------
//Get CLI options
$args = getargs($GLOBALS['argv']);
//Display Basic Help
if (isset($args['h']) || isset($args['help'])) {
echo "./your_php_cli_app.php -h ....\n";
echo " -h - displays this help\n";
echo " ... is more of your command line args\n";
echo "\n";
exit;
}
