示例 #1 Quickhash 示例
<?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 ) );
?>上面的示例将输出类似于
bool(true) bool(false) bool(true) bool(false)
示例 #2 Quickhash ArrayAccess 示例
<?php
$hash = new QuickHashIntHash( 64 );
// 添加和更新哈希条目。
$hash[3] = 145926;
$hash[3] = 1415926;
$hash[2] = 72;
// 检查键是否存在
var_dump( isset( $hash[3] ) );
// 删除哈希条目
unset( $hash[2] );
// 检索为哈希存储的值
echo $hash[3], "\n";
?>上面的示例将输出类似于
bool(true) 1415926
示例 #3 Quickhash 迭代器示例
<?php
$hash = new QuickHashIntHash( 64 );
// 添加哈希条目。
$hash[1] = 145926;
$hash[2] = 1415926;
$hash[3] = 72;
$hash[4] = 712314;
$hash[5] = -4234;
foreach( $hash as $key => $value )
{
echo $key, ' => ', $value, "\n";
}
?>上面的示例将输出类似于
5 => -4234 4 => 712314 1 => 145926 2 => 1415926 3 => 72
示例 #4 Quickhash 字符串值示例
<?php
$hash = new QuickHashIntStringHash( 64 );
// 添加哈希条目。
$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";
}
?>上面的示例将输出类似于
1 => one million four hundred fifteen thousand nine hundred twenty six 2 => one more
