Loop through two arrays?

Question

I have an array, I loop through it:

foreach($input['gallery'] as $galleryImg) {
}

But inside the loop, other than doing something for $input['gallery'], I also want to do something for $input['galleryData'].

How can I access each part of the gallery Data array in the same loop?

foreach($input['gallery'] as $galleryImg) {

     //do something for $galleryImg
     //do something for $input['galleryData'][$i?]
}

Dump of input:

{
    ["title"]=> string(0) ""
    ["date"]=> string(10) "30-09-2013"
    ["content"]=> string(0) ""
    ["galleryData"]=> string(149)
        "[
            {
                "comment":"$(this).data('comment')"
                ,"youTube":"$(this).data('youtube')"
            },
            {
                "comment":"$(this).data('comment')"
                ,"youTube":"$(this).data('youtube')"
            }
        ]"
    ["cover"]=> object(Symfony\Component\HttpFoundation\File\UploadedFile)#9 (7)
        {

                }

                    ["pathName":"SplFileInfo":private]=> string(14) "/tmp/phpA1u3vA"
                    ["fileName":"SplFileInfo":private]=> string(9) "phpA1u3vA"
                }
        }
}

Can you please show a `var_dump($input)` ... I guess that's more useful than to poke about in a fog. — djot, Sep 30 '13 at 14:19
@panthro: That doesn't look like an array. What's the actual array output? — Amal Murali, Sep 30 '13 at 14:44
Well I guess the question is simply: whither we can access two array in `foreach` loop. And [such a question](http://stackoverflow.com/questions/4480803/two-arrays-in-foreach-loop) already exists. — Sage, Sep 30 '13 at 16:26

Loop on your main array and add special action according to the array key :

foreach($input as $key => $value) {
     if($key == 'gallery') {
        foreach($value as $galleryValue) {
            //Do something with $galleryValue;
        }
     }
     else if ($key == 'galleryData') {
        $galleryData = json_decode($value);
     }
}

For a more robust code you can also check if $value is an array before the foreach just to be sure and avoid error

Have a +1 :) I'm not sure if one is supposed to delete the answer and post a new one, or edit the existing one, in cases like this. – user247702 Sep 30 '13 at 15:10
