JsonLite

日志文件

每行都是一个json字符串

{"a":1,"b":1,"c":2}
{"a":1,"b":1,"c":1}
{"a":2,"b":1,"c":1}
{"a":1,"b":1,"c":1}
{"a":1,"b":3,"c":1}
{"a":1,"b":1,"c":1}
{"a":2,"b":2,"c":1}

使用

初始化

include __DIR__."/../JsonLite.php";
$dataFile = __DIR__."/data.log";
$lite = new JsonLite($dataFile);

$dataFile为数据文件。

查询

查询方式尽量向MongoDB中的语句靠齐。

    $ret = $lite->find(array('a'=>2, 'b'=>2));
    echo json_encode($ret) . "\n";

结果为：

    [{"a":2,"b":2,"c":1}]

不等式判断：

    $ret = $lite->find(array('a'=>array('$gt'=>1)));
    echo json_encode($ret) . "\n";

结果为：

    [{"a":2,"b":1,"c":1},{"a":2,"b":2,"c":1}]
