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

This is a very useful function in PHP. PHP provides function to get the width and height of an image. The
getimagesize() function will determine the size of image file including flash file(swf).


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


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 ” .$width;
echo “<BR>”;
echo “Image height ” .$height;
echo “<BR>”;
echo “Image type ” .$type;
echo “<BR>”;
echo “Attribute ” .$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″
