在代码中引入jsonlint库,并使用其提供的方法来判断输入字符串是否为合法的JSON数据。 “`php require ‘vendor/autoload.php’; use Seld\JsonLint\JsonParser; function is_json($string) { $parser = new JsonParser(); try { $parser->parse($string); return true; } catch (\Exception $e) { return...
$array = json_decode($jsonString, true); 复制代码 减少数据量:在处理大量JSON数据时,尽量减少传输和处理的数据量。只传输和处理必要的数据,避免不必要的数据传输。 使用流式处理:当处理非常大的JSON文件时,可以考虑使用流式处理库(如salsify/jsonstreamingparser),这样可以在不加载整个文件到内存的情况下逐行解析...
$parser = new JsonParser(); $array = $parser->decode($jsonStr, JsonParser::DECODE_ASSOC); // 转换为数组 $object = $parser->decode($jsonStr); // 转换为对象 var_dump($array); var_dump($object); “` 3. 使用json_decode()和json_last_error()函数: 有时候,在处理JSON字符串时可能会...

This is a simple, streaming parser for processing large JSON documents. Use it for parsing very large JSON documents to avoid loading the entire thing into memory, which is how just about every other JSON parser for PHP works. For more details, I've written up a longer explanation of the...

由于json只接受utf-8编码的字符，所以json_encode()的参数必须是utf-8编码，否则会得到空字符或者null。
如果是 json 有没有类似 xpath 这种，能够直接根据条件定位数据，而不需要自行 json 解析在遍历获取。
