Get Width and Height of an Image in PHP

admin — Sat, 18 Dec 2010 10:15:39 +0000

PHP provides a function to get the width and height of an image. "getimagesize()" This function will determine the size of image file and also will get size of flash file(swf).

Syntax

list($width, $height, $type, $attr) = getimagesize("image_name.jpg");

|—|——————— code ——————–|—|

This is a sample code, change image_name to your image name and test it!




list($width, $height, $type, $attr) = getimagesize("image_name.jpg");
echo "Image width " .$width;

echo "
";

echo "Image height " .$height;

echo "
";

echo "Image type " .$type;

echo "
";

echo "Attribute " .$attr;



?>

When you run this script you will see the result like this

Image width 640
Image height 480
Image type 2
Image attribute width="640" height="480"

You will get the width, height, type of an image and also attribute of an image, I use this function in my image upload form.
Type of an image you can see from table below

Type of the image
1 = GIF	9 = JPC
2 = JPG	10 = JP2
3 = PNG	11 = JPX
4 = SWF	12 = JB2
5 = PSD	13 = SWC
6 = BMP	14 = IFF

In this script use rand(1, 100); to random number between 1 -100 and keep result in variable name "$result_rand" if result = 85 ad 2 will display.

|—|——————— code ——————–|—|


  

// random number 1 - 100 

$result_rand=rand(1, 100);
// if result less than or equal 70, display ad 1 (70%)

  if($result_rand<=70){

  echo "Display ad1";

  }

  

// if result less than or equal 90, display ad 2 (20%)

  elseif($result_rand<=90){

  echo "Display ad2";
