PHP: foreach limit 999 results

Question

foreach(array_slice(glob('/res/images/*.jpg'), 0, 999) as $filename)

is work fine but

foreach(array_slice(glob('/res/images/*.jpg'), 0, 1000) as $filename)

doesnt work. Where is I can change such limit?

Please expand on "doesn't work". What happens? Do you get an error? — IMSoP, Feb 18 '14 at 11:22
Not show result. Thinks and nothing happens. 999 response time 2 sec, 1000 not responce — TKVideoChat, Feb 18 '14 at 11:23
Maybe a [memory overflow](http://stackoverflow.com/a/12772851/1607098)? What about switching to [DirectoryIterator](http://php.net/directoryiterator)? — Touki, Feb 18 '14 at 11:26

Try with simple(May be the better) manner like

$i = 0;
foreach(glob('/res/images/*.jpg') as $filename) {
   if($i++ <= 1000) {
       // Do the display
   } else {
      break;
   }
}

For huge amount of possible files, I suggest to `break` in `else` block. – Pavel Štěrba Feb 18 '14 at 11:23
Thanks @PavelŠtěrba I have added it now.Actually I forgot it – GautamD31 Feb 18 '14 at 11:26
Or to simplify slightly, put `if($i++ > 1000) { break; }` at the top of the function, saving the extra indenting. However, I suspect this won't solve the OP's problem. – IMSoP Feb 18 '14 at 13:14

$i = 0;
$max = 1000;
foreach(array_slice(glob('/res/images/*.jpg'), 0, $max) as $filename) {
   // Some code here
   if($i++ >= $max) break;
}

Try this

Shortest Way to do like so.

$i = 0;
foreach(array_slice(glob('/res/images/*.jpg'), 0, 1000) as $filename) {
   // Some code here
   if($i++ >= 1000) break;
}

I hope it will be helpful.
