Help cleaning up my code a little?

PHP
1

basically this is like 60% written by me with a few copy/paste. What I am looking to do, is clean up this code a little. Functionally it does what I want it to relatively well, but it does look very very messy and I would like it to be a little more tidy.

Any suggestions on how to do this? I am no PHP expert as you can most likely tell by the code itself.

<?php

require(“cfg.php”);

//FOLDER PATH

$dir_cat= $imgpath;

$openDir_cat = opendir($dir_cat);

while (false !== ($fileNames_cat = readdir($openDir_cat))) {

$check_cat = $dir_cat. “/” . $fileNames_cat;

$size_cat = @getimagesize($check_cat);

// this check mime of file

if($fileNames == “.” || $fileNames_cat == “…” || strpos($size_cat[mime], “image”) === FALSE) {
continue; // exclude everything wha is not image
} else {
$imagesAll_cat = $fileNames_cat; // create an array of images
}
}

$imgnr_cat=0;

$imgct_cat=count(glob($dir_cat . “*”)); //COUNT THE NUMBER OF FILES IN THE UPLOAD DIR.

echo ‘<center><fieldset class=fieldset>’;

echo '<legend> IMGS ';

echo ’ (’ .$imgct_cat. ’ IMAGES)</legend><div>';

//GET IMAGES AND DISPLAY THEM

while ($imgnr_cat<$imgct_cat){

echo ‘<a href=’ .$dir_cat.$imagesAll_cat[$imgnr_cat]. ‘>’;

echo ‘<img width=140 height=100 src=’ .$dir_cat.$imagesAll_cat[$imgnr_cat]. ‘>’;

echo ‘</a>’;

$imgnr_cat++;

}

echo ‘</div></fieldset></center>’;

?>

This should work

<?php

require('cfg.php');

// Set the path to the folder
$dir = $imgpath;
$images = array();

// Make sure the directory exists
if (is_dir($dir)) {
    // Create a new directory handle
    if ($handle = opendir($dir_cat)) {
        // Loop through all the files in the directory
        while(false !== ($file = readdir($handle))) {
            // Get some information about the file
            $fileinfo = @getimagesize($dir_cat . '/' . $file);
            
            // Check the file mime type
            // Only append to the array if the file is an image
            if (strpos($fileinfo['mime'], 'image')) {
                $images[] = $file;
            }
        }
        
        closedir($handle);
        
        // List the images
        if (sizeof($images) > 0) {
            echo '<center><fieldset class="fieldset">';
            echo '    <legend> IMGS (' . count($images). ' IMAGES)</legend>';
            echo '    <div>';
            
            foreach($images as $image) {
                echo '<a href="' . $dir . $image . '"><img src="' . $dir . $image . '" width="140" height="100"></a>';
            }
            
            echo '    </div>';
            echo '</fieldset></center>';
        } else {
            echo 'No images exist in the directory (' . $dir . ')';
        }
    } else {
        echo 'An error has occurred while trying to open the directory (' . $dir . ')';
    }
} else {
    echo 'The directory (' . $dir . ') either doesn\\'t exist or cannot be opened due to insufficient permissions';
}

There are numerous Google references to formatting coding style. Here is the one that I follow:

The code you supplied looks a lot better and easier to read if enclosed using the [B]"wrap

```php


&lt;?php 
  require("cfg.php");
  //FOLDER PATH 
  $dir_cat= $imgpath; 
  $openDir_cat = opendir($dir_cat); 
  
  while (false !== ($fileNames_cat = readdir($openDir_cat)))
  { 
    $check_cat = $dir_cat. "/" . $fileNames_cat; 
    $size_cat = @getimagesize($check_cat); 
    // this check mime of file 

    if($fileNames == "." || $fileNames_cat == ".." || strpos($size_cat[mime], "image") === FALSE)
    { 
      continue; // exclude everything wha is not image 
    }else{ 
      $imagesAll_cat[] = $fileNames_cat; // create an array of images 
    } endif
  }//endwhile 

  $imgnr_cat=0;
  $imgct_cat=count(glob($dir_cat . "*")); //COUNT THE NUMBER OF FILES IN THE UPLOAD DIR.

  echo '&lt;center&gt;&lt;fieldset class=fieldset&gt;';
    echo '&lt;legend&gt; IMGS ';
    echo ' (' .$imgct_cat. ' IMAGES)&lt;/legend&gt;&lt;div&gt;';
    //GET IMAGES AND DISPLAY THEM

    while ($imgnr_cat&lt;$imgct_cat)
    { 
       echo '&lt;a href=' .$dir_cat.$imagesAll_cat[$imgnr_cat]. '&gt;';
       echo '&lt;img width=140 height=100 src=' .$dir_cat.$imagesAll_cat[$imgnr_cat]. '&gt;';
