PHP中的JSON有效格式

Question

I'm processing a lot of json files but some of them have invalid format.

Is there a library to find a JSON format error?

I want error messages like: "Found error line 100 after {"property":val{" to easily find the line and fix it manually.

Each json file has 500+ lines.

You can try to use a PHP tool like JSON Lint . Here is example usage in 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);
