如何在不使用file_get_contents的情况下在PHP中读取JSON文件？

Question

I've created a simple php file which reads a local json file and use the data to response to some queries sent to the page.

I'm using file_get_contents() to read the file. but as the requests count grown, I faced some performance issues because of concurrent connections to the file.

Is it possible to use require() or include() to read and parse the json file?

Answer 1

I've found some solution that fits, I'm now using curl to get the file contents like this:

$curlSession = curl_init();
curl_setopt($curlSession, CURLOPT_URL, 'http://mysite/file.json');
curl_setopt($curlSession, CURLOPT_BINARYTRANSFER, true);
curl_setopt($curlSession, CURLOPT_RETURNTRANSFER, true);
$jsonDataString = curl_exec($curlSession);
curl_close($curlSession);

Yes, you can use require()

 ob_start();
 ob_implicit_flush(false);
 require('test.json');
 $json = json_decode(ob_get_clean() , true );

but I think its not faster than file_get_contents()

The best way for performance is to load json-file to browser directly (eg by jquery) without php-parsing.
