Answer 1

Try using PHP glob - it returns an array of filenames in any folder you give it. You can filter by *.jpg, and just use the first item in the array.

For example, I use:

$imageArray = glob($folder . "/image*.jpg");

which makes an array of all filenames called image[something].jpg in the folder $folder.

wow, I wonder if you can have your entire program written for you by just asking questions!

try to do it yourself, post your best try, and ask specific questions when you run into a problem.

<?php

$record_ratio = 0;
foreach (glob("*.jpg") as $filename) {
    $info = getimagesize($filename);
    $ratio = $info[0] / $info[1];
    if (abs(1 - $ratio) < abs(1 - $record_ratio)) {
      $record_ratio = $ratio;
      $record_filename = $filename;
    }
    if (record_ratio == 1) break;
}
if ($record_ratio > 0) {
  echo '<img src="'.$record_filename.'" height=150px><br>';
}

?>

<?php
foreach (glob("*.txt") as $filename) {
     echo nl2br(file_get_contents($filename));
        echo "<br></br>";
}
?>
