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

Answer 1

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

Answer 2

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

Answer 3

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

Answer 4

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";
}
