listing images

[fricx]

Hello, I am trying to list images from folder, and i have managed to that. But, I want to limit number of images the code will show. Here is my code:

 

<?php

$imgdir = 'uploads/image/'; 
$allowed_types = array('jpg','jpeg'); 
$a_img = glob($imgdir."*.{".implode(',',$allowed_types)."}",GLOB_BRACE);
sort($a_img);

echo '<table cellspacing="0" cellpadding="6"><tr>';         
foreach ($a_img as $img) {
  if ($colCount % 6.5 == 0) echo "</tr><tr>";
  $colCount++;
  $showimage = basename($img);
  echo '<td><div class="smallpic" style="width:100px;height:75px;"><a href="../index.php?pic='.$showimage.'"><img src="../uploads/image/'.$showimage.'" width="100" height="75" border="0" onclick="changeImg(velika, "'.$showimage.'")" /></a></div</td>';
}
echo "</tr></table>";

?>

 

So my question is how to limit above code to show only for example 4 images.

Perhaps you may want to use a for loop instead of foreach.

for($i=0;$i<LIMIT;$i++) {
//your code here
}

From the looks of your code it seems you're trying to create a multi column gallery of some sort.

have you looked at the following? http://www.phpfreaks.com/forums/index.php/topic,95426.0.html

Since glob returns an array, you can use array_slice to get a specific slice of it (e.g. $a_imgs = array_slice($a_img, 0, 10); to get the first 10 files).

Thank you salathe, array_slice() never came on my mind. The thin I did was that I used asort function to sort images in array in ascending order and then used array_slice() to define number of images to show.

 

 

Thank you very much !

You're welcome. I do tend to find that folks 'forget' about the range of array (and same for string) functions and just need reminding.
