使用php从另一个文件读取对象的问题

Question

I have some file called main.config which has:

{"name":"wtf","image":"main.PNG","desc":"This is about this that and that.","tags":{"php","js","html"}}

Now in php I am reading this file and getting its content like this:

$string = "";
$handle = fopen("main.config", "r");
while(!feof($handle)){
  $string .= fgets($handle);
}
fclose($handle);

And now I have been trying to decode this but it always return either null or string with additional "" around.

"{"name":"wtf","image":"main.PNG","desc":"This is about this that and that.","tags":{"php","js","html"}}"

This is everything I tried:

json_decode( preg_replace('/[\x00-\x1F\x80-\xFF]/', '', $string), true );
json_decode(preg_replace('/\s+/', '',$string), true);
json_decode(preg_replace('/\x{FEFF}/u', '', $string), true);
json_decode(str_replace('"', '"', $string));
utf8_encode($string); 
stripslashes($string);
trim($string);
html_entity_decode($string);
json_decode(print_r($string, true), true);

But nothing seems to work, is it because I used some different file type or what could it be?

Answer 1

It was just an invalid json formatted string.

Change to:

{"name":"wtf","image":"main.PNG","desc":"This is about this that and that.","tags":["php","js","html"]}

You can also read the content with less code using:

json_decode(file_get_contents('main.config', true);

If you want to validate json format you can use this site also: jsonlint.com
