Bug description:Ability to override the hash function used by SplObjectStorage
Description:
------------
SplObjectStorage will be a lot more useful if I could override the hash
function
it uses, so different objects which are really equal will be recognized as
such by
SplObjectStorage.
While I currently do this by jumping through a few hoops, this will be a
welcome
addition. A __hashCode() magic method can accomplish this easily.
Test script:
---------------
Pseudo-code:
<?
class StockSecurity {
public $exchange;
public $ticker;
public function __hashCode() {
return $this->exchange . ":" . $this->ticker;
}
}
$d = new SplObjectStorage();
$s = new StockSecurity( 'NASDAQ', 'GOOG' );
$d->attach( $s, getStockQuote( $s ) );
// later on, in a different method
$s = new StockSecurity( 'NASDAQ', 'GOOG' );
$quote = $d[ $s ];
