Exemple #1 QuickHashIntSet::add() example
<?php
echo "without dupe checking\n";
$set = new QuickHashIntSet( 1024 );
var_dump( $set->exists( 4 ) );
var_dump( $set->add( 4 ) );
var_dump( $set->exists( 4 ) );
var_dump( $set->add( 4 ) );
echo "\nwith dupe checking\n";
$set = new QuickHashIntSet( 1024, QuickHashIntSet::CHECK_FOR_DUPES );
var_dump( $set->exists( 4 ) );
var_dump( $set->add( 4 ) );
var_dump( $set->exists( 4 ) );
var_dump( $set->add( 4 ) );
?>
Résultat de l'exemple ci-dessus est similaire à :
without dupe checking bool(false) bool(true) bool(true) bool(true) with dupe checking bool(false) bool(true) bool(true) bool(false)
