$size_info = getimagesize($image_file);

$size_info[0] : image width

$size_info[1] : image height

$size_info[2] : image format (ex, 1:GIF, 2:JPG, 3:PNG, 4:SWF, 5:PDF, 6:BMP, 7:TIFF(intel byte order), 8:TIFF(motolola byte order), 9:JPC, 10:JP2, 11:JPX)

샘플테스트

 

 

$image_file = "test_001.jpg"; // width='180' height='171'

$size_info = getimagesize($image_file);
$a = $size_info[0]; 
$b = $size_info[1]; 
$c = size_info[2]; 
$d = size_info[3];
