Using Logical AND Operators && in foreach php - php

Question

I have the following code for an image gallery :
$directory = 'some path';
$thumbs_directory = 'some path';
foreach (glob($directory.'/*.{jpg,jpeg,png,gif}', GLOB_BRACE) as $file)
foreach (glob($thumbs_directory.'/*.{jpg,jpeg,png,gif}', GLOB_BRACE) as $file2)
{
if($file=='.' || $file == '..') continue;
$file_parts = explode('.',$file);
$ext = strtolower(array_pop($file_parts));
$title = basename($file);
$title = htmlspecialchars($title);
$title = str_replace("_"," ",$title);
$nomargin='';
if(($i+1)%4==0) $nomargin='nomargin';
echo '
<div class="pic '.$nomargin.'" style="background:url('.$file2.') no-repeat 50% 50%;">
'.$title.'
</div>';
$i++;
}
I need to combine these foreach statements through the Logical AND operator && so that both conditions are satisfied at the same time. Is it possible ? I've tried numerous times, but always ends up in a Syntax error.
Please note that I need $file and $file2 variables defined perfectly. That is only the way for the thumbnails to associate with the images properly.

Answer 1

Can you not simply refactor the meaty logic into a common function, and then call it twice?
For example:
function doSomething($directory) {
foreach (glob($directory.'/*.{jpg,jpeg,png,gif}', GLOB_BRACE) as $file) {
/* Whatever */
}
}
...
doSomething($directory);
doSomething($thumbs_directory);

Answer 2

Based on your description, if you want to loop over the image files that exist in both directories, you should look into using php's array_intersect().
$directory = 'some path';
$thumbs_directory = 'some path';
$files_in_dir1 = glob($directory.'/*.{jpg,jpeg,png,gif}', GLOB_BRACE);
$files_in_dir2 = glob($thumbs_directory.'/*.{jpg,jpeg,png,gif}', GLOB_BRACE);
$files_in_both_dirs = array_intersect($files_in_dir1, $files_in_dir2);
foreach ($files_in_both_dirs as $filename) {
// Code
}

Answer 3

To map images to their respective thumbnail images, I would rather choose a different approach:
$directory = 'some path';
$thumbs_directory = 'some path';
// Get all images
$images = glob($directory.'/*.{jpg,jpeg,png,gif}', GLOB_BRACE);
// Iterate over all images
foreach ($images as $image) {
// Construct path to thumbnail
$thumbnail = $thumbs_directory .'/'. basename($image);
// Check if thumbnail exists
if (!file_exists($thumbnail)) {
continue; // skip this image
}
// .. continue as before
echo '
<div class="pic '.$nomargin.'" style="background:url('.$thumbnail.') no-repeat 50% 50%;">
'.$title.'
</div>
';
}
}
