说明

public static QuickHashStringIntHash::loadFromString ( string $contents [, int $size = 0 [, int $options = 0 ]] ) : 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

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";}?>
