Aerospike::predicateRange - helper method for building the range WHERE predicate
public array Aerospike::predicateRange ( string $bin, int $index_type, int $min, int $max )
Aerospike::predicateRange() will return an array that can be passed as the $where arguement in Aerospike::query().
Similar to predicateBetween(), predicateRange() looks for records with a range of values inside a complex type - a list containing the values (if the index type is INDEX_TYPE_LIST), the values contained in the keys of a map (if the index type is INDEX_TYPE_MAPKEYS), or a record with the given values contained in the values of a map (if the index type was INDEX_TYPE_MAPVALUES).
bin the bin name operand
index_type one of Aerospike::INDEX_TYPE_* .
min the integer value to start with
max the integer value to end with
Returns an array with the following structure:
Associative Array:
bin => bin name
op => Aerospike::OP_RANGE
val => array
or NULL on failure.
<?php
$config = ["hosts" => [["addr"=>"localhost", "port"=>3000]], "shm"=>[]];
$client = new Aerospike($config, true);
if (!$client->isConnected()) {
echo "Aerospike failed to connect[{$client->errorno()}]: {$client->error()}\n";
exit(1);
}
// assume that the bin 'movies' contains a map of title => views
$where = Aerospike::predicateRange("movies", Aerospike::INDEX_TYPE_MAPVALUES, 10, 999);
var_dump($where);
?>We expect to see:
array(4) {
["bin"]=>
string(6) "movies"
["index_type"]=>
int(3)
["op"]=>
string(5) "RANGE"
["val"]=>
array(2) {
[0]=>
int(10)
[1]=>
int(999)
}
}
