QuickHashStringIntHash
This factory method creates a new hash from a definition in a string. The format is the same as the one used in "loadFromFile".
参数
-
contents -
The string containing a serialized format of the hash.
-
size -
The amount of bucket lists to configure. The number you pass in will be automatically rounded up to the next power of two. It is also automatically limited from 4 to 4194304.
-
options -
The same options that the class' constructor takes; except that the size option is ignored. It is automatically calculated to be the same as the number of entries in the hash, rounded up to the nearest power of two with a maximum limit of 4194304.
返回值
Returns a new QuickHashStringIntHash.
范例
Example #1 QuickHashStringIntHash::loadFromString() example
<?php
$contents = file_get_contents( dirname( __FILE__ ) . "/simple.hash.string" );
$hash = QuickHashStringIntHash::loadFromString(
$contents,
QuickHashStringIntHash::DO_NOT_USE_ZEND_ALLOC
);
foreach( range( 0, 0x0f ) as $key )
{
$i = 48712 + $key * 1631;
$k = base_convert( $i, 10, 36 );
echo $k, ' => ', $hash->get( $k ), "\n";
}
?>
以上例程的输出类似于：
11l4 => 48712 12uf => 50343 143q => 51974 15d1 => 53605 16mc => 55236 17vn => 56867 194y => 58498 1ae9 => 60129 1bnk => 61760 1cwv => 63391 1e66 => 65022 1ffh => 66653 1gos => 68284 1hy3 => 69915 1j7e => 71546 1kgp => 73177
