QuickHashIntStringHash::loadFromString
(PECL quickhash >= Unknown)
QuickHashIntStringHash::loadFromString — This factory method creates a hash from a string
Description
$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
