How to extract a particular string from a String variable in php?

Question

I have string values related to images in a variable $photo covered by curly braces. I get this value from MySQL table. It has Image name, alt text, and image caption together in the string variable $photo. I want to extract image name, alt, and image caption covered by curly brackets.

I've added code that has the string value below,

<?php
$photo =' {"imagename":
    {"filename":"imagename.jpg","alt":"Hunting Rifle","caption":"This is Hunter Image"}
}';
?>

I want to get filename and alt stings separately and store it in new variables separately[$filename,$alt] .

Anyone knows how to extract these particular strings from a string variable ?

That's JSON, so use json_decode.

$jdphoto = json_decode($photo);

$imagename = $jdphoto->imagename;

$filename = $imagename->filename;
$alt = $imagename->alt;
$caption = $imagename->caption;
