How to get the Dimensions of an Image using PHP
PHP has a very interesting function to obtain information about images: getimagesize () .
With this feature which facilitates the PHP library you can find out the size of an image file, the dimensions (width, height), and file type (gif, jpg, png, etc …) and attributes (width = “” height = “”) with the height / width to be used within the IMG HTML tag).
Image types returned by the function :
|1 = GIF||5 = PSD||9 = JPC||13 = SWC|
|2 = JPG||6 = BMP||10 = JP2||14 = IFF|
|3 = PNG||7 = TIFF||11 = JPX||15 = WBMP|
|4 = SWF||8 = TIFF||12 = JB2||16 = XBM|
Characteristics of the sample image obtained with the getimagesize () function
list($width, $height, $type, $attr) = getimagesize("php-logo.png"); echo "Width:" $ width;. echo "Height: " .$height; echo "Type: " .$type; echo "Attributes: " .$attr;
Attributes: width = “397” height = “255”
