Javascript scope.

错误／异常

• Throws MongoDB\Driver\Exception\InvalidArgumentException on argument parsing errors.
• Throws MongoDB\Driver\Exception\InvalidArgumentException if code contains null bytes.

更新日志

版本	说明
PECL mongodb 1.2.0	MongoDB\Driver\Exception\InvalidArgumentException is thrown if code contains null bytes. Previously, values would be truncated at the first null byte.

范例

Example #1 MongoDB\BSON\Javascript::__construct() example

<?php$code = new MongoDB\BSON\Javascript('function() { return 1; }');var_dump($code);$codews = new MongoDB\BSON\Javascript('function() { return foo; }', ['foo' => 'bar']);var_dump($codews);?>

以上例程会输出：

object(MongoDB\BSON\Javascript)#1 (2) {
  ["javascript"]=>
  string(24) "function() { return 1; }"
  ["scope"]=>
  object(stdClass)#2 (0) {
  }
}
object(MongoDB\BSON\Javascript)#2 (2) {
  ["javascript"]=>
  string(26) "function() { return foo; }"
  ["scope"]=>
  object(stdClass)#1 (1) {
    ["foo"]=>
    string(3) "bar"
  }
}
