PHP JSONPath, XPath contains filter

I using JSONPath with PHP and i need the xpath equivalent to the contains filter, "contains(dept, 'Management')";

I have the following JSON and i want to filter the staff members to the Management Dept only. If the department node only contains 1 department then it's no problem, but i need find the keyword within department string?

Any help would be appreciated.

{ 
    "staff": {
        "members": [ 
            { 
            "firstname": "J",
                "lastname": "H",
                "department": "Management, Finance"
            },
   开发者_高级运维         { 
                "firstname": "S",
                "lastname": "M",
                "department": "Finance"
            }
        ]
    }
}

$parser->setPath("$..members[?(@['department']=='Management')]");
$staff = $parser->getData();
var_dump($staff);

Look at this

JSONPath :contains filter

I would assume in your case wil be something like.

"$..members[?(/Management/.test(@['department']))";

I managed to figure this out. There are examples found in http://jsonpath.googlecode.com/svn/trunk/tests/jsonpath-test-php.php which use PHP strpos, but this didn't work for me initially using jsonpath-0.8.1.php.

I gave jsonpath-0.8.3.php found the the repository and the strpos expression worked perfectly:-

$..members[?(@ && @['department'] && strpos(@['department'],'".$dept."')!==false)]

Note, the function evalx() has a third parameter which causes errors, setting the value to null works fine, see http://code.google.com/p/jsonpath/issues/detail?id=8

function evalx($x, $v, $vname=null)
