display image from a directory and text from a text file - php

Question

a current project of mine is giving me some trouble. The web page in question is supposed to display text from a text file followed by an accompanying image from a directory.
Currently, the output is text 1, image 1, text 2, image 1, text 1, image 2, text 2, image 2
My code so far:
foreach ($DirEntries as $Entry)
{
if((strcmp($Entry, '.') != 0) && (strcmp($Entry, '..') != 0))
{
$inputFile = fopen("imagelist.txt", "r");
if ($inputFile)
{
while (($line = fgets($inputFile)) !== false)
{
echo "Name, description, and file name:<br />" . $line."<br>";
echo "<img src=\"files/" . $Entry . "\" ><br /><br />\n";
}
}
else
{
echo "There was an error in the opening file";
}
fclose($inputFile);
}
}
closedir($DirOpen);
?>
Any help would be greatly appreciated.

Your problem appears to be the nested while loop since you're dealing with a one to one relationship.
This should solve the problem for you:
$inputFile = fopen("imagelist.txt", "r");
// probably better to check for file readability before looping the directory items.
if (!$inputFile) {
echo "There was an error in the opening file";
}
else {
foreach ($DirEntries as $entry)
{
if($entry === '.' || $entry === '..')
{
continue; // using a continue helps keeps the code indentation levels down.
}
// assuming that each line corresponds to an image in the same order
if (($line = fgets($inputFile)))
{
echo "Name, description, and file name:<br />" . $line."<br>";
echo "<img src=\"files/" . $entry . "\" ><br /><br />\n";
}
else
{
echo "Image '$entry' has no metadata";
}
}
fclose($inputFile);
}
closedir($DirOpen);
Good luck!
