Yii2 mongodb 扩展的where的条件增加大于 小于号

1. mongodb的where中有比較丰富的 条件。例如以下：

 static $builders = [
            'NOT' => 'buildNotCondition',
            'AND' => 'buildAndCondition',
            'OR' => 'buildOrCondition',
            'BETWEEN' => 'buildBetweenCondition',
            'NOT BETWEEN' => 'buildBetweenCondition',
            'IN' => 'buildInCondition',
            'NOT IN' => 'buildInCondition',
            'REGEX' => 'buildRegexCondition',
            'LIKE' => 'buildLikeCondition',
			
        ];

增加函数部分为：

在vendor/yiisoft/yii2-mongodb/collection.php

增加函数：

	public function buildGtCondition($operator, $operands)
    {
        if (!isset($operands[0], $operands[1])) {
            throw new InvalidParamException("Operator '$operator' requires two operands.");
        }
        list($column, $value) = $operands;
        return [$column => ['?gt' => $value]];
    }
	
	
	public function buildGteCondition($operator, $operands)
    {
        if (!isset($operands[0], $operands[1])) {
            throw new InvalidParamException("Operator '$operator' requires two operands.");
        }
        list($column, $value) = $operands;
        return [$column => ['?gte' => $value]];
    }
	
	
	public function buildLtCondition($operator, $operands)
    {
        if (!isset($operands[0], $operands[1])) {
            throw new InvalidParamException("Operator '$operator' requires two operands.");
        }
        list($column, $value) = $operands;
        return [$column => ['?lt' => $value]];
    }
	
	public function buildLteCondition($operator, $operands)
    {
        if (!isset($operands[0], $operands[1])) {
            throw new InvalidParamException("Operator '$operator' requires two operands.");
        }
        list($column, $value) = $operands;
        return [$column => ['?
lte' => $value]];
    }

 public function buildCondition($condition)
    {
        static $builders = [
            'NOT' => 'buildNotCondition',
            'AND' => 'buildAndCondition',
            'OR' => 'buildOrCondition',
            'BETWEEN' => 'buildBetweenCondition',
            'NOT BETWEEN' => 'buildBetweenCondition',
            'IN' => 'buildInCondition',
            'NOT IN' => 'buildInCondition',
            'REGEX' => 'buildRegexCondition',
            'LIKE' => 'buildLikeCondition',
			'>' 	=> 'buildGtCondition',
			'>='	=> 'buildGteCondition',
			'<' 	=> 'buildLtCondition',
			'<=' 	=> 'buildLteCondition',
        ];

/**
 * Collection represents the Mongo collection information.
 *
 * A collection object is usually created by calling [[Database::getCollection()]] or [[Connection::getCollection()]].
 *
 * Collection provides the basic interface for the Mongo queries, mostly: insert, update, delete operations.
 * For example:
 *
 * ~~~
 * $collection = Yii::$app->mongodb->getCollection('customer');
 * $collection->insert(['name' => 'John Smith', 'status' => 1]);
 * ~~~
 *
 * To perform "find" queries, please use [[Query]] instead.
 *
 * Mongo uses JSON format to specify query conditions with quite specific syntax.
 * However Collection class provides the ability of "translating" common condition format used "yii\db\*"
 * into Mongo condition.
 * For example:
 * ~~~
 * $condition = [
 *     [
 *         'OR',
 *         ['AND', ['first_name' => 'John'], ['last_name' => 'Smith']],
 *         ['status' => [1, 2, 3]]
 *     ],
 * ];
 * print_r($collection->buildCondition($condition));
 * // outputs :
 * [
 *     '$or' => [
 *         [
 *             'first_name' => 'John',
 *             'last_name' => 'John',
 *         ],
 *         [
 *             'status' => ['$in' => [1, 2, 3]],
 *         ]
 *     ]
 * ]
 * ~~~
 *
 * Note: condition values for the key '_id' will be automatically cast to [[\MongoId]] instance,
 * even if they are plain strings. However, if you have other columns, containing [[\MongoId]], you
 * should take care of possible typecast on your own.
 *
 * @property string $fullName Full name of this collection, including database name. This property is
 * read-only.
 * @property array $lastError Last error information. This property is read-only.
 * @property string $name Name of this collection. This property is read-only.
