How to Upload Image using PHP?

Here you can learn Upload Image and at a same time information stored into database.

//define a maxim size for the uploaded images in Kb
 define (“MAX_SIZE”,”100″);

//This function reads the extension of the file. It is used to determine if the file  is an image by checking the extension.
 function getExtension($str) {
         $i = strrpos($str,”.”);
         if (!$i) { return “”; }
         $l = strlen($str) – $i;
         $ext = substr($str,$i+1,$l);
         return $ext;

 function UploadImage(){
//reads the name of the file the user submitted for uploading
//if it is not empty
if ($image)
//get the original name of the file from the clients machine
$filename = stripslashes($_FILES[‘image’][‘name’]);
//get the extension of the file in a lower case format
$extension = getExtension($filename);
$extension = strtolower($extension);
//if it is not a known extension, we will suppose it is an error and will not  upload the file,
//otherwise we will do more tests
if (($extension != “jpg”) && ($extension != “jpeg”) && ($extension != “png”) && ($extension != “gif”))

//print error message
echo ‘<h1>Unknown extension!</h1>’;
//get the size of the image in bytes
//$_FILES[‘image’][‘tmp_name’] is the temporary filename of the file
//in which the uploaded file was stored on the server

//compare the size with the maxim size we defined and print error if bigger
if ($size > MAX_SIZE*1024)
echo ‘<h1>You have exceeded the size limit!</h1>’;

//we will give an unique name, for example the time in unix time format
//the new name will be containing the full path where will be stored (images folder)
//we verify if the image has been uploaded, and print error instead

$copied = copy($_FILES[‘image’][‘tmp_name’], $newname);
if (!$copied)
echo ‘<h1>Copy unsuccessfull!</h1>’;
return $newname;

//This variable is used as a flag. The value is initialized with 0 (meaning no error  found)
//and it will be changed to 1 if an errro occures.
//If the error occures the file will not be uploaded.
//checks if the form has been submitted

  $car_header_image = UploadImage();

$car_about_descr = $_POST[‘txtDesc’];

$str_car_about_page = “select * from car_about where car_aboutID = ‘1’ “;

$result = mysql_query($str_car_about_page);

$rows  = mysql_num_rows($result);

if($rows > 0){
$update_car_about_page = “update car_about set car_header_image = ‘” . $car_header_image . “‘ , car_about_descr = ‘” . $car_about_descr . “‘”;

mysql_query($update_car_about_page );

$insert_car_about_page = “insert into car_about(car_header_image, car_about_descr) values(‘” . $car_header_image . “‘, ‘” . $car_about_descr . “‘)”;



//If no errors registred, print the success message
 if(isset($_POST[‘Submit’]) && !$errors)
  echo “<h1>File Uploaded Successfully! Try again!</h1>”;
