Get the width and height of an image using a function in PHP


############### Code
This is a sample code, change image_name to your image name and test it!
<?php
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 379
Image height 344
Image type 2
Image attribute width="379" height="344"

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.
