Beispiel #1 QuickHashIntStringHash::add() example
<?php
echo "without dupe checking\n";
$hash = new QuickHashIntStringHash( 1024 );
var_dump( $hash->exists( 4 ) );
var_dump( $hash->get( 4 ) );
var_dump( $hash->add( 4, "twenty two" ) );
var_dump( $hash->exists( 4 ) );
var_dump( $hash->get( 4 ) );
var_dump( $hash->add( 4, "twelve" ) );
echo "\nwith dupe checking\n";
$hash = new QuickHashIntStringHash( 1024, QuickHashIntStringHash::CHECK_FOR_DUPES );
var_dump( $hash->exists( 4 ) );
var_dump( $hash->get( 4 ) );
var_dump( $hash->add( 4, "seventy eight" ) );
var_dump( $hash->exists( 4 ) );
var_dump( $hash->get( 4 ) );
var_dump( $hash->add( 4, "nine" ) );
?>
Das oben gezeigte Beispiel erzeugt eine ähnliche Ausgabe wie:
without dupe checking bool(false) bool(false) bool(true) bool(true) string(10) "twenty two" bool(true) with dupe checking bool(false) bool(false) bool(true) bool(true) string(13) "seventy eight" bool(false)
