Export Json Array to CSV in php - php

Question

I have this array of provider
[
{
"reference":"01042",
"images": [
"http:\/\/static1.provider.com\/34\/01042.jpg"
]
},
{
"reference":"01057",
"images":[
"http:\/\/static1.provider.com\/57\/01057.jpg",
"http:\/\/static3.provider.com\/58\/01057.jpg",
"http:\/\/static2.provider.com\/59\/01057.jpg"]
},
...
]
I export with the following code
$json_file2 = file_get_contents('http://direct.provider.com/public/ref_urlimage_20.json', false);
$decoded = json_decode($json_file2);
$fp = fopen('imagenes.csv', 'w');
foreach($decoded as $comment) {
fputcsv($fp, $comment);
}
fclose($fp);
but it shows me the following result
01104,Array
01119,Array
40460,Array
00311,Array
00312,Array
00307,Array
When you need to export to this format
01104,http://static3.provider.com/155/01119.jpg
01119,http://static3.provider.com/155/04519.jpg,http://static3.provider.com/155/01148.jpg,http://static3.provider.com/155/0859.jpg
40460,http://static3.provider.com/155/01119.jpg,http://static3.provider.com/155/01118.jpg
00351,http://static3.provider.com/175/07219.jpg
...
Where am I doing wrong?
Thanks

if (empty($argv[1])) die("The json file name or URL is missed\n");
$jsonFilename = $argv[1];
$json = file_get_contents($jsonFilename);
$array = json_decode($json, true);
$f = fopen('output.csv', 'w');
$firstLineKeys = false;
foreach ($array as $line)
{
if (empty($firstLineKeys))
{
$firstLineKeys = array_keys($line);
fputcsv($f, $firstLineKeys);
$firstLineKeys = array_flip($firstLineKeys);
}
$line_array = array($line['reference']);
foreach ($line['images'] as $value)
{
$line_array.push($value);
}
fputcsv($f, $line_array);
}
Since You have array inside looping like the above code might help solve the issue
Try the below code this will work
<?php
//if (empty($argv[1])) die("The json file name or URL is missed\n");
//$jsonFilename = $argv[1];
//
//$json = file_get_contents($jsonFilename);
$json_file2 = file_get_contents('http://direct.funidelia.es/public/ref_urlimage_20.json', false);
error_reporting(E_ALL);
//echo $json_file2;die;
$json='{"data":'.$json_file2.'}';
//echo $json;
$array = json_decode($json, true);
//echo "<pre>";
//print_r($array);
//die;
$f = fopen('output.csv', 'w');
$firstLineKeys = false;
foreach ($array["data"] as $line)
{
// echo "<pre>";
// print_r($line);
// die;
if (empty($firstLineKeys))
{
$firstLineKeys = array_keys($line);
fputcsv($f, $firstLineKeys);
$firstLineKeys = array_flip($firstLineKeys);
}
$line_array = array($line['reference']);
foreach ($line['images'] as $value)
{
array_push($line_array,$value);
}
fputcsv($f, $line_array);
}
echo "Success";
?>
