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 "
";
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.
