PHP - Image Help

[foochuck]

I have about 20 images on my php page. I'd like to somehow have PHP add up the total width of the pixels of each image. Is this possible?

 

Thanks

 

FOO

The answer is: yes.

Touche'...

 

Can someone give me any tips on how to accomplish this? I'm not sure what functions to use or where to even start...

[DarkWater]

Put the picture names in an array and do:

 

foreach ($array_name as $v) {

   $image_dim = get_image_size("/path/to/file/$v.jpg");

   $total += $image_dim[1];

}

 

All the files have to be in the same folder (or all have relative paths to the same folder otherwise it won't work right.

[foochuck]

Thanks DarkWater, I'll give that a try.

[DarkWater]

Just put in the right variables before you come back here and say "OMG IT DOESN'T WORK". =P

[foochuck]

Yes sir. Thanks again.

[DarkWater]

No problem. =)

[foochuck]

No problem. =)

 

Can I throw one more twist at you?

 

I'd like to figure out the tallest "height" out of all of the images in my array as well. How can I accomplish this?

[DarkWater]

 

Change the foreach code to this:

foreach ($array_name as $v) {

    $image_dim = get_image_size("/path/to/file/$v.jpg");

    $total += $image_dim[1];

    $heights[] = $image_dim[1];

}

$highest = current(end(sort($heights, SORT_NUMERIC)));

echo $highest;

 

Rofl, try that.  Kind of convoluted, but I can't think of an easier way right now, although I know there is one.

 

 

[DarkWater]

Woops.  I forgot that sort() and end() don't return an array, but actually pass it by reference.  Here, this code works, I tried it:

 

foreach ($array_name as $v) {

    $image_dim = get_image_size("/path/to/file/$v.jpg");

    $total += $image_dim[1];

    $heights[] = $image_dim[1];

}

 

sort($heights, SORT_NUMERIC);

end($heights);

$highest = current($heights);

echo $highest;

FYI - Shouldn't the function be getimagesize rather than get_image_size ?

[DarkWater]

Yes yes, I wasn't thinking.  I typed getimagesize on my test script on my server, lol, which is rather ironic.  But the code for getting the max numeric value in an array works fine.  There's probably already a function for it, but it isn't coming to me, so just use that. xD

[foochuck]

One other thing - I think $image_dim[1] should be $image_dim[0] - because I need the width attribute, not height.

[DarkWater]

You said height:

=P  [0] is for width though if you do need it.
