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

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

This is a very useful function in PHP, I found it on php.net 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).

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!

<?php

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"

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.
