preg_split() on file names

[Cetanu]

Hi! 

 

I'm currently developing a photography portfolio for a friend. To display his images, rather than using a database and allowing it to get massive, I've decided to go ahead and stick them into a directory and then cycle through it. As it's currently set up, I open the directory and read it, use preg_split() to divide the files up according to file type, and then use a foreach() statement to display them.

 

It works like a charm. But now I have a problem: I want to limit the amount of files that are echoed out. I've tried everything. Using this:

$i = 0; 
foreach($images as $image){ 
// blahblahblah 
$i++ 
if($i > 10){ 
break; 
} 
}

 

And that doesn't work. :|

And I also decided to try and count() the array and stuff. Nothing worked.

 

Furthermore, print_r() returns this:

Array ( [0] => [1] => a_message.jpg [2] => ) Array ( [0] => [1] => cold_call.jpg [2] => ) Array ( [0] => [1] => ring_of_love.jpg [2] => ) Array ( [0] => thumbs ) Array ( [0] => [1] => unclear.jpg [2] => )

 

Isn't it supposed to return ONE array with different keys?! >.>

 

Here is the code:

$img_dir = "images/photographs/"; 
		if(is_dir($img_dir)){ 
			if($img_handle = opendir($img_dir)){
				echo "<div id=\"index_thumbnails\"><div id=\"hidden_images\">"; 
				while(($img = readdir($img_handle)) !== false){
					if($img !== "Thumbs.db" && $img !== "." && $img !== ".."){
						$images = preg_split('/([a-zA-Z0-9_-]*\.jpg$)/', $img, 0, PREG_SPLIT_DELIM_CAPTURE); 
							if(empty($images)){ 
								echo "<b>Sorry, there are no images to display!</b>"; 
							} 
							else{						
								foreach($images as $img_display){									
									if($img_display !== "" && $img_display !== "thumbs"){ 
										$img_name = "images/photographs/{$img_display}"; 
										$thumb_path = "images/photographs/thumbs/"; 
										$size = getimagesize($img_name); 
										$width = $size['0']; 
										$height = $size['1']; 
										$nwidth = round($width/20); 
										$nheight = round($height/20);
										$img_thumb = imagecreatefromjpeg("{$img_name}"); 
										$resized = imagecreatetruecolor($nwidth, $nheight); 
										imagecopyresampled($resized, $img_thumb, 0, 0, 0, 0, $nwidth, $nheight, $width, $height); 
										imagejpeg($resized, "{$thumb_path}{$img}_thumb.jpg"); 
										echo "<img src=\"{$thumb_path}{$img}_thumb.jpg\" height=\"{$nheight}\" width=\"{$nwidth}\"/>";
										} 
									}	

							}

						print_r($images);
					} 
				} 
				closedir($img_handle);
				echo "</div></div>"; 
			} 
		}

 

Bear with the fact that I'm not using a function to shrink my images. xD I'm getting all of the work out of the way before I make a function and link it to a database to get image information.

 

 

All help is appreciated! Thank you!

Return a slice of your array:

 

$imgarray = array_slice($imgarray, 0, 10);

<?php
// image and thumb paths
$img_dir = "images/photographs/"; 
$thumb_path = "images/photographs/thumbs/";

// get first $amount of images from dir
$amount=3;
$images = array_map('basename',glob($img_dir . "*.jpg"));
$images = array_slice($images,0,$amount);

// create and output thumbs
foreach ($images as $image) {
  $size = getimagesize($img_dir.$image); 
  $width = $size['0']; 
  $height = $size['1']; 
  $nwidth = round($width/20); 
  $nheight = round($height/20);
  $img_thumb = imagecreatefromjpeg($img_dir.$image); 
  $resized = imagecreatetruecolor($nwidth, $nheight); 
  imagecopyresampled($resized, $img_thumb, 0, 0, 0, 0, $nwidth, $nheight, $width, $height); 
  imagejpeg($resized, $thumb_path.$image); 
  echo "<img src='{$thumb_path.$image}' height='{$nheight}' width='{$nwidth}'/>";
} // end foreach
?>
