Removing double quotes from a string from JSON response in PHP

Question

I am using this code that I got from git, and when I get the BlockChain API response while getting the address from the wallet, the address is enclosed in double quotes like below. 

"43Hua8Qz1dj82ddoyLBe448HAXShsuBCAp"

I want to remove these double quotes because it might create syntax errors. But I am not sure how to do it. Please help

This is the code I am using:

$resp = file_get_contents($blockchain_receive_root . "v2/receive?key=" . $my_api_key . "&gap_limit=".$gap_limit. "&callback=" . urlencode($callback_url) . "&xpub=" . $my_xpub);
$response = json_decode($resp);

print json_encode($response->address);

How to remove the quotes?

Why are you using json_encode?

Hi @Himesh. I am just using the code that was available on git. Didn't add the line. I am new to Json so don't much.

Answer 1

Just remove the json_encode call, and it should work:

$resp = file_get_contents($blockchain_receive_root . "v2/receive?key=" . $my_api_key . "&gap_limit=".$gap_limit. "&callback=" . urlencode($callback_url) . "&xpub=" . $my_xpub);
$response = json_decode($resp);

print $response->address;

Hey, thanks for the solution. Can you please tell what json_encode does?

json_encode is a PHP function that is used to convert PHP objects to Json object. So when you use json_encode, the PHP object is getting converted to Json object and that's why you are seeing double quotes. 

Answer 2

You are getting double quotes because the line json_encode is encoded it into an address and that's why you can double quotes when you print it. If you don't use the encoding, it should be fine. 

Answer 3

You can use the replace method to replace the double quotes with nothing. Here's the code to do that. 

var test = "\"43Hua8Qz1dj82ddoyLBe448HAXShsuBCAp\"";
console.log(test);
console.log(test.replace(/\"/g, ""));
