Get Image Height and Width as integer values?

I've tried to use t开发者_运维百科he PHP function getimagesize, but I was unable to extract the image width and height as an integer value.

How can I achieve this?

Try like this:

list($width, $height) = getimagesize('path_to_image');

Make sure that:

1. You specify the correct image path there
2. The image has read access
3. Chmod image dir to 755

Also try to prefix path with $_SERVER["DOCUMENT_ROOT"], this helps sometimes when you are not able to read files.

list($width, $height) = getimagesize($filename)

Or,

$data = getimagesize($filename);
$width = $data[0];
$height = $data[1];

getimagesize() returns an array containing the image properties.

list($width, $height) = getimagesize("path/to/image.jpg");

to just get the width and height or

list($width, $height, $type, $attr)

to get some more information.

Like this :

imageCreateFromPNG($var);
//I don't know where from you get your image, here it's in the png case
// and then :
list($width, $height) = getimagesize($image);
echo $width;
echo $height;

PHP's getimagesize() returns an array of data. The first two items in the array are the two items you're interested in: the width and height. To get these, you would simply request the first two indexes in the returned array:

var $imagedata = getimagesize("someimage.jpg");

print "Image width  is: " . $imagedata[0];
print "Image height is: " . $imagedata[1];

For further information, see the documentation.

getimagesize('image.jpg') function works only if allow_url_fopen is set to 1 or On inside php.ini file on the server, if it is not enabled, one should use ini_set('allow_url_fopen',1); on top of the file where getimagesize() function is used.
