Example #1 SplObjectStorage::setInfo() example
<?php
$s = new SplObjectStorage ();
$o1 = new StdClass ;
$o2 = new StdClass ;
$s -> attach ( $o1 , "d1" );
$s -> attach ( $o2 , "d2" );
$s -> rewind ();
while( $s -> valid ()) {
$s -> setInfo ( "new" );
$s -> next ();
}
var_dump ( $s [ $o1 ]);
var_dump ( $s [ $o2 ]);
?>
以上例程的输出类似于:
string(3) "new" string(3) "new"
