php copy image from array url - php

Question

I'm trying to copy images from an array of URLs with the following code. The problem is it only saves the last picture, anyone knows why is this?
foreach($photos['data'] as $photo)
{
echo "guardando:";
echo $photo['id'];
$idFoto++;
$fp = fopen('foto'.$idFoto.'.jpg', 'wb');
curl_setopt($ch, CURLOPT_URL, $photo['source']);
curl_setopt($ch, CURLOPT_FILE, $fp);
curl_setopt($conn[$i], CURLOPT_RETURNTRANSFER, 1);
curl_setopt($ch, CURLOPT_HEADER, 0);
curl_exec($ch);
curl_close($ch);
fclose($fp);
}

I think your problem is in curl_close($ch), this call should be outside for bucle or maybe you could call curl_init for each photo also could check if curl_setopt is returning true or false:
foreach($photos['data'] as $photo)
{
echo "Guardando $idFoto: $photo['source']\n";
$idFoto++;
$fp = fopen('foto'.$idFoto.'.jpg', 'wb');
$ch=curl_init();
curl_setopt($ch, CURLOPT_URL, $photo['source']);
//curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($ch, CURLOPT_FILE, $fp);
curl_setopt($ch, CURLOPT_HEADER, 0);
if(curl_exec($ch)===false) echo "Error: ".curl_error()."\n";
fclose($fp);
curl_close($ch);
}
Also note CURLOPT_RETURNTRANSFER is not needed because we are saving to file and not assigning curl_exec return. Could you test please?
