How to store SPL Iterator results (rather than just echo-and-forget):
The library of Iterators are object based, so you need to trick the little rascals into an array.
Here's how (two ways) ...
1. Explicit typecasts: $a[] = (array)$Obj->objMethod();
2. Array definition: $a[] = array( key => $Obj->objMethod() );
Examples: DirectoryIterator()
*/
// 1. explicity typecast object as array
foreach ( new DirectoryIterator('./') as $Item )
{
$fname = (array)$Item->getFilename();
$dir_listing[] = $fname[0];
}
//
echo "<pre>";
print_r($dir_listing); unset($dir_listing);
echo"</pre><hr />";
//
// or
// 2. define array as key => object->method
foreach ( new DirectoryIterator('./') as $Item )
{
$dir_listing[] = array (
"fname" => $Item->getFilename(),
"path" => $Item->getPathname(),
"size" => $Item->getSize(),
"mtime" => $Item->getMTime()
);
}
//
echo "<pre>";
print_r($dir_listing); unset($dir_listing);
echo"</pre>";
//
