Usage

Include jsonpath.php in your HTML page and use the simple API consisting of one single function.

jsonPath(obj, expr [, args])

parameters:

obj (array):

Array representing the JSON structure. expr (string): JSONPath expression string. args (object|undefined): Object controlling path evaluation and output. Currently only one member is supported. args['resultType'] ("VALUE"|"PATH"): causes the result to be either matching values (default) or normalized path expressions.

return value:

(array|false):

Example

This example uses the Services_JSON class from Michal Migurski's JSON parser (http://mike.teczno.com/json.html). ``` JSONPath - Example (php)

decode($json);

$out = "";
$out .= $parser->encode(jsonPath($o, "$.store.book[*].author")) . "\n";
$out .= $parser->encode(jsonPath($o, "$..author")) . "\n";
$out .= $parser->encode(jsonPath($o, "$.store.*")) . "\n";
$out .= $parser->encode(jsonPath($o, "$.store..price")) . "\n";
$out .= $parser->encode(jsonPath($o, "$..book[(count(@)-1)]")) . "\n";
$out .= $parser->encode(jsonPath($o, "$..book[-1:]")) . "\n";
$out .= $parser->encode(jsonPath($o, "$..book[0,1]")) . "\n";
$out .= $parser->encode(jsonPath($o, "$..book[:2]")) . "\n";
$out .= $parser->encode(jsonPath($o, "$..book[?(@['isbn'])]")) . "\n";
$out .= $parser->encode(jsonPath($o, "$..book[?(@['price']encode(jsonPath($o, "$..*")) . "\n";

print($out);
?>

```
