# Examples

Example #1 Quickhash Example

`<?php
$set = new QuickHashIntSet( 1024, QuickHashIntSet::CHECK_FOR_DUPES );
$set->add( 1 );
$set->add( 3 );
var_dump( $set->exists( 3 ) );
var_dump( $set->exists( 4 ) );
$set->saveToFile( "/tmp/test-set.set" );
$newSet = QuickHashIntSet::loadFromFile(
"/tmp/test-set.set"
);
var_dump( $newSet->exists( 3 ) );
var_dump( $newSet->exists( 4 ) );
?>`

The above example will output something similar to:

    bool(true)
    bool(false)
    bool(true)
    bool(false)

Example #2 Quickhash ArrayAccess Example

`<?php
$hash = new QuickHashIntHash( 64 );
// Adding and updating hash entries.
$hash[3] = 145926;
$hash[3] = 1415926;
$hash[2] = 72;
// Checking if keys exist
var_dump( isset( $hash[3] ) );
// Removing hash entries
unset( $hash[2] );
// Retrieving the value stored for a hash
echo $hash[3], "\n";
?>`

The above example will output something similar to:

    bool(true)
    1415926

Example #3 Quickhash Iterator Example

`<?php
$hash = new QuickHashIntHash( 64 );
// Adding hash entries.
$hash[1] = 145926;
$hash[2] = 1415926;
$hash[3] = 72;
$hash[4] = 712314;
$hash[5] = -4234;
foreach( $hash as $key => $value )
{
echo $key, ' => ', $value, "\n";
}
?>`

The above example will output something similar to:

    5 => -4234
    4 => 712314
    1 => 145926
    2 => 1415926
    3 => 72

Example #4 Quickhash String Values Example

`<?php
$hash = new QuickHashIntStringHash( 64 );
// Adding hash entries.
$hash[1] = "one million four hundred fifteen thousand nine hundred twenty six";
$hash->add( 2, "one more" );
foreach( $hash as $key => $value )
{
echo $key, ' => ', $value, "\n";
}
?>`

The above example will output something similar to:

    1 => one million four hundred fifteen thousand nine hundred twenty six
    2 => one more
