QuickHashIntStringHash::loadFromString — This factory method creates a hash from a string

Descrição

public static QuickHashIntStringHash::loadFromString(string $contents, int $size = 0, int $options = 0): QuickHashIntStringHash

This factory method creates a new hash from a definition in a string. The format is the same as the one used in "loadFromFile".

Parâmetros

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.

Valor Retornado

Returns a new QuickHashIntStringHash.

Exemplos

Exemplo #1 QuickHashIntStringHash::loadFromString() example

<?php
$contents = file_get_contents( dirname( __FILE__ ) . "/simple.hash" );
$hash = QuickHashIntStringHash::loadFromString(
    $contents,
    QuickHashIntStringHash::DO_NOT_USE_ZEND_ALLOC
);
foreach( range( 0, 0x0f ) as $key )
{
    printf( "Key %3d (%2x) is %s\n",
        $key, $key,
        $hash->exists( $key ) ? 'set' : 'unset'
    );
}
?>

O exemplo acima produzirá algo semelhante a:

Key   0 ( 0) is unset
Key   1 ( 1) is set
Key   2 ( 2) is set
Key   3 ( 3) is set
Key   4 ( 4) is unset
Key   5 ( 5) is set
Key   6 ( 6) is unset
Key   7 ( 7) is set
Key   8 ( 8) is unset
Key   9 ( 9) is unset
Key  10 ( a) is unset
Key  11 ( b) is set
Key  12 ( c) is unset
Key  13 ( d) is set
Key  14 ( e) is unset
Key  15 ( f) is unset
