The source code for the file is:

Please help me out, thank you. I will really appreciate it. If you need any extra information, please let me know. Thank you. I know you guys are really smart and can surely help me out. Sorry for bad english.

Answer 1

The response returned by twitter API is in json format, You need to convert it to array.

$feed = json_decode($feed);

The above line will convert json into an array. Use it after you get API response.
