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
