(PECL quickhash >= Unknown)

QuickHashIntStringHash::loadFromStringThis factory method creates a hash from a string

Description

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

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

Parameters

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.

Return Values

Returns a new QuickHashIntStringHash.

Examples

Example #1 QuickHashIntStringHash::loadFromString() example

<?php
$contents 
file_get_contentsdirname__FILE__ ) . "/simple.hash" );
$hash QuickHashIntStringHash::loadFromString(
    
$contents,
    
QuickHashIntStringHash::DO_NOT_USE_ZEND_ALLOC
);
foreach( 
range00x0f ) as $key )
{
    
printf"Key %3d (%2x) is %s\n",
        
$key$key
        
$hash->exists$key ) ? 'set' 'unset'
    
);
}
?>

The above example will output something similar to:

 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
