<?php
//generate 200000 elements
$array range0199999 );
$existingEntries array_randarray_flip$array ), 180000 );
$testForEntries array_randarray_flip$array ), 1000 );
$foundCount 0;

echo 
"Creating hash: "microtimetrue ), "\n";
$hash = new QuickHashIntHash100000 );
echo 
"Adding elements: "microtimetrue ), "\n";
foreach( 
$existingEntries as $key )
{
     
$hash->add$key56 );
}

echo 
"Doing 1000 tests: "microtimetrue ), "\n";
foreach( 
$testForEntries as $key )
{
     
$foundCount += $hash->exists$key );
}
echo 
"Done, $foundCount found: "microtimetrue ), "\n";
