CollectionFind::bind — Bind value to query placeholder
It allows the user to bind a parameter to the placeholder in the search condition of the find operation. The placeholder has the form of :NAME where ':' is a common prefix that must always exists before any NAME, NAME is the actual name of the placeholder. The bind function accepts a list of placeholders if multiple entities have to be substituted in the search condition.
placeholder_values
Values to substitute in the search condition; multiple values are allowed and are passed as an array where "PLACEHOLDER_NAME => PLACEHOLDER_VALUE".
A CollectionFind object, or chain with execute() to return a Result object.
Example #1 mysql_xdevapi\CollectionFind::bind() example
<?php$session = mysql_xdevapi\getSession("mysqlx://user:password@localhost");$session->sql("DROP DATABASE IF EXISTS addressbook")->execute();$session->sql("CREATE DATABASE addressbook")->execute();$schema = $session->getSchema("addressbook");$create = $schema->createCollection("people");$result = $create ->add('{"name": "Alfred", "age": 18, "job": "Butler"}') ->execute();// ...$collection = $schema->getCollection("people");$result = $collection ->find('job like :job and age > :age') ->bind(['job' => 'Butler', 'age' => 16]) ->execute();var_dump($result->fetchAll());?>
The above example will output something similar to:
array(1) { [0]=> array(4) { ["_id"]=> string(28) "00005b6b536100000000000000cf" ["age"]=> int(18) ["job"]=> string(6) "Butler" ["name"]=> string(6) "Alfred" } }
