A method for displaying photo exif information in PHP _php tips

PHP programming enables you to display photo exif information and display thumbnail effects in the picture, with the following code:

? /** * Functions to obtain image information * A function to obtain image information completely * @access public * @param string $img picture path * @return Array/function Getimageinfoval ($Im
  Ageinfo, $val _arr) {$InfoVal = "unknown";
