Getting width and height of an image in php

There is a builtin function in php to get the width and height of an image. The getimagesize()function determines the size of image also including flash file(swf).

Here is the code to get basic information such as width, height, type and attribute of any image

<?php

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

echo "Image width " .$width."\n";

echo "Image height " .$height."\n";

echo "Image type " .$type."\n";

echo "Attribute " .$attr."\n";

?>

Output

Image width 749
Image height 695
Image type 2
Attribute width="749" height="695"

so this is the way to get the width and height of any image in php.
