Help displaying images in a folder

[sac0o01]

I am using the following to display all the images within a folder.  How could I limit the number of images displayed to a set number, for example 10?

 

$files = glob("temp/*.png");

for ($i=1; $i<count($files); $i++)
{
$num = $files[$i];
echo '<img src="'.$num.'" alt="random image">'."  ";
}

Hi,

 

example break from the for loop like this:

 

$num_of_images = 10;
for ($i=1; $i<count($files); $i++)
{
$num = $files[$i];
echo '<img src="'.$num.'" alt="random image">'."  ";

if ($i >= $num_of_images)
break;
}

 

or

 

$num_of_imgs = count($files);
$num_of_imgs = ($num_of_imgs > 11) ? 11 : $num_of_imgs;
for ($i=1; $i<$num_of_imgs; $i++)
{
$num = $files[$i];
echo '<img src="'.$num.'" alt="random image">'."  ";
}

Thanks!  Works great!  I understand the first one but could you explain how this line in the second one works?  Operators still give me a rough time.

 

$num_of_imgs = ($num_of_imgs > 11) ? 11 : $num_of_imgs;

Youre welcome.

 

Thats the ternary operator: (condition statement) ? 'if condition is true this will be the actual value' : 'if condition is false than this'

Thanks so much, looks like I have some more studying to do.
