# QuickHashIntStringHash::loadFromString

(PECL quickhash >= Unknown)

QuickHashIntStringHash::loadFromString — This 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_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'
);
}
?>`

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
