<?php
 $dir =       'images';

$file_display = array ('jpg');

if (file_exists ($dir) == false) {
echo 'Directory \'', $dir,'\' not found!';


} else {
  $dir_contents = scandir ($dir);


foreach ($dir_contents as $file) {
	$file_type = strtolower (end (explode('.', $file)));



	if ($file !=='.' && $file !== '..' && in_array($file_type, $file_display) ==true) {
	echo '<img style="height: 100px;" alt="" src="', $dir, '/', $file, '" alt="', $file, '">';
}

}
}

?>

One way to do it would be to use [man]array_slice[/man] on [font=monospace]$dir_contents[/font] - after filtering it, instead of filtering it during display.

You could just add a loop counter variable:

$counter = 0;
foreach($dir_contents as $file) {
    if(++$counter > 5) {
        break;
    }
    // rest of loop code
}

PS: Or slice up the array like Weedpacket suggested, I've done that at times, too.

okay, Thanks NogDog! where in my current code do i post it?

[tobymac]

im not getting it to work...

here is what i now have

<?php
 $dir =       'images';

$file_display = array ('jpg');

if (file_exists ($dir) == false) {
echo 'Directory \'', $dir,'\' not found!';


} else {
  $dir_contents = scandir ($dir);


$counter = 0;
foreach($dir_contents as $file) {
    if(++$counter > 2) {
        break;
    }

	$file_type = strtolower (end (explode('.', $file)));



	if ($file !=='.' && $file !== '..' && in_array($file_type, $file_display) ==true) {
	echo '<img style="height: 100px;" alt="" src="', $dir, '/', $file, '" alt="', $file, '">';

}  

}

}

?>

After looking a bit more closely at what you're doing, I might take the slicing idea and use glob() to get the files, so it can do the filtering for you.

$files = glob($dir.'/*.jpg');
$first5files = array_slice($files, 0, 5);
foreach($first5files as $file) {
    echo '<img style="height: 100px;" alt="" src="', $file, '" alt="', basename($file), '">';
}

okay, i posted it. now it is only showing 1 photo... not 5. here is my updated code

 <?php
 $dir =       'images';

$file_display = array ('jpg');

if (file_exists ($dir) == false) {
echo 'Directory \'', $dir,'\' not found!';


} else {
  $dir_contents = scandir ($dir);


$files = glob($dir.'/*.jpg');
$first5files = array_slice($files, 0, 5);
foreach($first5files as $file) {
    echo '<img style="height: 100px;" alt="" src="', $file, '" alt="', basename($file), '">';

}
}

?>

Your code works fine for me; are you sure you have more than one file that ends in ".jpg" (not ".JPG", et al.) in this 'images' folder?

[Derokorian]

Note also, if you are running this on a unix system, the extensions are case sensitive, so jpg != JPG

Close: If you are running this on a system using a case-sensitive file system, that is true. For example, you could be using a *nix-based OS but be accessing an NTFS partition/volume, in which case the filenames would be case insensitive.

EDIT: You raise a good point, though; because of this ambiguity, I've trained myself to always treat file paths as case sensitive to the point where I forget I'm doing it.

QFT however I've noticed this behavior as problematic since I've moved to the (not so) wonderful world of .NET
