JSONLint

JSONLint是Java开发中常用的一款文件，可进行多种功能的实现，新版本修正了PHP 5.3在bin/jsonlint中的兼容性，增加了使用jsonlint二进制文件一次lint多个文件的能力，需要的朋友可以来本站下载！

使用说明

php

use Seld\JsonLint\JsonParser;

$parser = new JsonParser();

// returns null if it's valid json, or a ParsingException object.

$parser->lint($json);

// Call getMessage() on the exception object to get

// a well formatted error message error like this

// Parse error on line 2:

// ... "key": "value" "numbers": [1, 2, 3]

// ----------------------^

// Expected one of: 'EOF', '}', ':', ',', ']'

// Call getDetails() on the exception to get more info.

// returns parsed json, like json_decode() does, but slower, throws

// exceptions on failure.

$parser->parse($json);

```

You can also pass additional flags to `JsonParser::lint/parse` that tweak the functionality:

- `JsonParser::DETECT_KEY_CONFLICTS` throws an exception on duplicate keys.

- `JsonParser::ALLOW_DUPLICATE_KEYS` collects duplicate keys. e.g. if you have two `foo` keys they will end up as `foo` and `foo.2`.

- `JsonParser::PARSE_TO_ASSOC` parses to associative arrays instead of stdClass objects.

Example:

```

$parser = new JsonParser;

try {

$jsonParser->parse(file_get_contents($jsonFile), JsonParser::DETECT_KEY_CONFLICTS);

} catch (DuplicateKeyException $e) {

$details = $e->getDetails();

echo 'Key '.$details['key'].' is a duplicate in '.$jsonFile.' at line '.$details['line'];

}
