# QuickHashIntHash::loadFromString

(PECL quickhash >= Unknown)

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

### Description

public static QuickHashIntHash QuickHashIntHash::loadFromString ( string `$contents` [, int `$options` ] )

This factory method creates a new hash from a definition in a string. The file format consists of 32 bit signed integers packed together in the Endianness that the system that the code runs on uses. For each element there are two 32 bit signed integers stored. The first of each element is the key, and the second is the value belonging to the key.

### Parameters

`contents`

  The string containing a serialized format of the hash.

`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 QuickHashIntHash.

### Examples

Example #1 QuickHashIntHash::loadFromString() example

`<?php
$contents = file_get_contents( dirname( __FILE__ ) . "/simple.hash" );
$hash = QuickHashIntHash::loadFromString(
$contents,
QuickHashIntHash::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
