I am trying to read a JSON file (approx 8KB) using the file_get_contents() method but the browser gives an error saying can't reach the site. I don't think that the file size is a problem because I can read larger (e.g. 10KB) HTML or other files using the same function. My JSON file contains comments and I have a function that removes all the comments in order to give valid json to json_decode(). I've even tried to rename the JSON file (currently names config.json) but it didn't worked. It seems like the contents are the problem but I don't know how to solve this issue. I am using WAMP in Windows. Below is the error screen my browser is showing.
Following is the code to read and var_dump() JSON:
<?php
function clear($data) {
return preg_replace("#(/\*([^*]|[\r\n]|(\*+([^*/]|[\r\n])))*\*+/)|([\s\t]//.*)|(^//.*)#", '', $data);
}
$data = file_get_contents('login/config.json');
$data = clear($data);
var_dump($data);
?>
And the JSON file is below:
{
/*
