PHP :
<?php
// File upload path
$uploadPath = "uploads/";
// If file upload form is submitted
$status = $statusMsg = '';
if(isset($_POST["submit"])){
$status = 'error';
if(!empty($_FILES["image"]["name"])) {
// File info
$fileName = basename($_FILES["image"]["name"]);
$imageUploadPath = $uploadPath . $fileName;
$fileType = pathinfo($imageUploadPath, PATHINFO_EXTENSION);
// Allow certain file formats
$allowTypes = array('jpg','png','jpeg','gif');
if(in_array($fileType, $allowTypes)){
// Image temp source
$imageTemp = $_FILES["image"]["tmp_name"];
// Compress size and upload image
$compressedImage = compressImage($imageTemp, $imageUploadPath, 75);
if($compressedImage){
$status = 'success';
$statusMsg = "Image compressed successfully.";
}else{
$statusMsg = "Image compress failed!";
}
}else{
$statusMsg = 'Sorry, only JPG, JPEG, PNG, & GIF files are allowed to upload.';
}
}else{
$statusMsg = 'Please select an image file to upload.';
}
}
function compressImage($source, $destination, $quality)
{
// Get image info
$imgInfo = getimagesize($source);
$mime = $imgInfo['mime'];
// Create a new image from file
switch($mime){
case 'image/jpeg':
$image = imagecreatefromjpeg($source);
break;
case 'image/png':
$image = imagecreatefrompng($source);
break;
case 'image/gif':
$image = imagecreatefromgif($source);
break;
default:
$image = imagecreatefromjpeg($source);
}
// Save image
imagejpeg($image, $destination, $quality);
// Return compressed image
return $destination;
}
echo $statusMsg;
?>- Define the upload path
- If form submitted, check $_FILES[“image”][“name”] is empty or not
- if empty, show eror message indicating upload a file
- If not empty,
- get the basename to filename
- set the upload path
- get the image extension to check whether it is allowed or not
- if allowed type call the compressImage() to compress image. Pass image details as parameter.
- compressImage()
- get size of image by getimagesize()
- get the image mime type
- create a new image by passing the source to imagecreatefromjpeg() function. imagecreatefromjpeg() function will create a new image from url.
- imagejpeg() will output image to browser or file
