PHP function getimagesize can get the picture width high information

Array getimagesize (string $filename [, Array & $imageinfo])

Returns an array with four cells. Index 0 contains the pixel value of the image width, and index 1 contains the pixel value of the image height. Index 2 is a marker of the image type: 1 = gif,2 = jpg,3 = png,4 = swf,5 = psd,6 = bmp,7 = TIFF (Intel byte order), 8 = TIFF (Motorola byte order), 9 = jpc,10 = jp2,11 = jpx,12 = jb2,13 = swc,14 = iff,15 = wbmp,16 = XBM. These tags correspond to the newly added IMAGETYPE constants of PHP 4.3.0. Index 3 is a text string with the content "height=" yyy "width=" xxx ", which can be used directly with the IMG tag.

This is the PHP official website manual: Http://php.net/manual/en/function.get ...

Add a Demo:

$images _array = Array ("Http://static.zend.com/img/logo.gif"), foreach ($images _array as $image) {list ($width, $height, $type, $attr) = getimagesize ($image), $new _height = (int) (192/$width * $height); Echo '
';}

Are you going to pin the picture in a box?

Picture Adaptive//function Image_fix_to_box (obj,width,height) {var owidth = Obj.width;var Oheight = Obj.height;var R1 = parseFloat (obj.width)/parsefloat (obj.height), var r2 = parsefloat (width)/parsefloat (height), if (Math.Abs (R1-R2) < 0.0001) {OB J.width = Width;obj.height = height;} else if (R1 < r2) {obj.height = Height;obj.width = parseint (parsefloat (height)/parsefloat (oheight)  * owidth);} Else{obj.width = Width;obj.height = parseint (parsefloat (width)/parsefloat (owidth) * oheight);}}
