I've got a temporary fix but still the iterator always return true,
still hope someone could help me out to point out the problem:)
//parseOptions utilitiese by tgckpg
function parseOptions ( $argStream, $handler ) {
//Chop first useless argument -- argv[0]
array_shift ( $argStream ) ;
//Initiate ArrayObject for iterator
$arrayobject = new ArrayObject ( $argStream ) ;
//Initiate iterator for iteration
$iterator = $arrayobject->getIterator();
//If options is set first
if( $iterator->valid() && preg_match ( '/^-\w$/', $iterator->current()
) ) {
//iterate through whole argument stream
for ( ; $iterator->valid(); $iterator->next() ) {
//Check if reached next option
if( preg_match ( '/^-\w$/', $opts =
$iterator->current() ) ) {
//Get current options
$currOpt = $opts;
//echo "$currOpt\n";
//Test if next stream is an option
for ( $iterator->next(); $iterator->valid();
$iterator->next() ) {
if ( preg_match ( '/^-\w$/', $opts =
$iterator->current() ) ) {
//echo "$currOpt $opts\n";
$handler($currOpt);
$currOpt = $opts;
} else break;
//var_dump($iterator->valid());
}
}//End if
//echo "$currOpt $opts\n";
$handler($currOpt, $opts);
//A temporary fix for infinite
loop<--
if(!$iterator->valid())
break;
}// End for
//If option is not set first.
} else {
//Try other approach.
}// End if
}
