echo results from an google safe browsing api array

I know this is a basic question, but I cannot figure out how to actually do this. I have read countless tutorials about it but they seemingly do not work.

var_dump($google_check);

returns the following:

string(488) "{
  "matches": [
    {
      "threatType": "MALWARE",
      "platformType": "LINUX",
      "threat": {
        "url": "http://malware.testing.google.test/testing/malware/"
      },
      "cacheDuration": "300s",
      "threatEntryType": "URL"
    },
    {
      "threatType": "MALWARE",
      "platformType": "LINUX",
      "threat": {
        "url": "http://malware.testing.google.test/testing/malware/"
      },
      "cacheDuration": "300s",
      "threatEntryType": "URL"
    } 
  ]
} 
"

I want to echo results from the array, so something like

echo $google_check[0][matches][threat];
echo $google_check[1][matches][threat];

Problem is this returns illegal offset on matches and threat, and only echo's a single character {

What am I doing wrong? How do I echo the results from this array without dumping the entire array?

The response you recieved is in json so you'll need to first json_decode the response.

$decoded = json_decode($google_check, true);

Then you can access it like an array

echo $decoded['matches'][0]['threat'];
echo $decoded['matches'][1]['threat'];

if you want the url value you'll need to do it like this.

echo $decoded['matches'][0]['threat']['url'];
echo $decoded['matches'][1]['threat']['url'];

please also note, when looking at array keys that aren't numerical you'll need to wrap in quotes (e.g. $decoded['matches'] instead of $decoded[matches]).

Here's a quick explanation on json
