Uploaded ZIP archive. Convert only PNG to JPEG in PHP - php

Question

For the life of me, I cant figure out how to code part of this process:
Ive Already Completed These Steps:
1. Upload ZIP archive (containing only photos in gif, png, and jpg)
2. Unpack to folder
3. Scan folder for filenames + file extentions
I Need Help With:
4. Convert only PNG to JPG
Any help would be appreciated!

EDIT:
Does this make sense?
$directory = "../images/ilike/goldfish/";
$images = glob($directory . "*.jpg");
foreach($images as $image)
{
$pic = imagecreatefrompng($directory);
$bg = imagecreatetruecolor(imagesx($image), imagesy($image));
imagefill($bg, 0, 0, imagecolorallocate($bg, 255, 255, 255));
imagealphablending($bg, TRUE);
imagecopy($bg, $pic, 0, 0, 0, 0, imagesx($image), imagesy($image))
imagedestroy($image);
imagejpeg($bg, $image . ".jpg", 100);
ImageDestroy($bg);
}

Answer 1

Take in the file from a form as usual, open it with http://www.php.net/manual/en/class.ziparchive.php and use http://www.php.net/manual/en/ziparchive.extractto.php to extract the files to an empty folder. Then using the PHP standard file handling functions scan filenames that end with .jpg. Load them in with http://www.php.net/manual/en/function.imagecreatefromjpeg.php and then save them out with http://www.php.net/manual/en/function.imagepng.php .

//here we create directory
----------------------------
$new_folder=mkdir('C:\\wamp\\www\\TestImage\\uploads\\'.$folder_name, 0777, true);
$path="uploads\\".$folder_name."\\";
//uploading files
-----------------------------
$fileName = $_FILES["upload_file"]["name"]; // The file name
$fileTmpLoc = $_FILES["upload_file"]["tmp_name"]; // File in the PHP tmp folder
$fileType = #$_FILES["upload_file"]["application/zip"]; // The type of file it is
$fileSize = $_FILES["upload_file"]["size"]; // File size in bytes
$fileErrorMsg = $_FILES["upload_file"]["error"]; // 0 = false | 1 = true
$kaboom = explode(".",$_FILES["upload_file"]["name"]); // Split file name into an array using the dot
$fileExt = end($kaboom); // Now target the last array element to get the file extension
if (!preg_match("/.(zip)$/i", $fileName) ) {
// This condition is only if you wish to allow uploading of specific file types
//echo "ERROR: Your file was not .zip file";
echo "Please select image files.Supported format are .Zip</br>";
unlink($fileTmpLoc); // Remove the uploaded file from the PHP temp folder
#exit();
}
//unzip to specific location
--------------------------------
if(preg_match("/.(zip)$/i", $fileName))
{
$moveResult= move_uploaded_file($fileTmpLoc, $fileName);
if($moveResult == true)
{
$zip = new ZipArchive;
$res = $zip->open($fileName);
if($res==TRUE)
{
$zip->extractTo($path.$fileName);
echo "<pre>";
print_r($zip);
$zip->close();
} else {
echo 'failed';
}
}
unlink($fileName); // Remove the uploaded file from the PHP temp folder
//exit();
}
//function for Convert only PNG to JPG
$image = imagecreatefrompng($originalFile);
imagejpeg($image, $outputFile, $quality);//$outputFile->define name of output file and $quality is a number between 0 (best compression) and 100 (best quality)
imagedestroy($image);
