                    }
                ]
            }

My PHP code

<?php 
  for ($i=0; $i < sizeof($value->albumimages); $i++) 
  { 
    $x = count($value->albumimages); 
    switch($x) 
    { 
      break; 
      default: 
        if($i == 0 || $i == 1) 
        { 
          echo '<div class="col-sm-6 pads5 marb10"> <img class="full" src="'.getapiPath().$imgs->imagepath.'"> </div>'; 
        } 
        break; 
    } 
  } 
?>

I want albumimages->imagepath

albumimages); $i++) { $x = count($value->albumimages); switch($x) { break; default: if($i == 0 || $i == 1) { echo '

'; } break; } } ?> — Maulik Kanani, Jun 20 '17 at 08:57

I think what you are looking for is json_decode($data, true);

This makes the json data an array that you can use like var_dump($data["albumimages"])

Working example: https://3v4l.org/Q9lkW
And to loop through the links you can do foreach, https://3v4l.org/9rRSF

The data is in json format so convert the data into php object by using 'json_encode()' function. This function converts the json data into php object the access the property by using php object operator.

$data = json_encode('your_json_string');
//and access like this
$data[0]->albumimages

You can use the foreach loop to access the 'imagepath' like this

//get the albumsimages
$albumimages = $data[0]->albumimages;

//then use foreach to access the imagepath like this
foreach($albumimages as $image) {
    echo $image->imagepath ."\n";
}

Use this code

$a = json_decode('YOUR JSON STRING',true);
foreach($a['data'][0] as $key => $value){
    if($key == 'albumimages'){
        for($i = 0; $i < count($value); $i++){
            foreach($value[$i] as $k => $v){
                echo "Key: ".$k." Value: ".$v."<br/>";
            }
        }
    }
}

Output will be like this

Key: imagepath Value: /Images/18/Albums/newalbum2/Screenshot_from_2017-06-12_15-11-36.png

Key: imagepath Value: /Images/18/Albums/newalbum2/Screenshot_from_2017-06-12_15-11-361.png

Key: imagepath Value: /Images/18/Albums/newalbum2/Screenshot_from_2017-06-12_15-11-363.png

Key: imagepath Value: /Images/18/Albums/newalbum2/Screenshot_from_2017-06-12_15-11-364.png

Key: imagepath Value: /Images/18/Albums/newalbum2/Screenshot_from_2017-06-12_15-11-365.png
