本文实例讲述了php生成图片缩略图的方法。分享给大家供大家参考。具体如下：
这里需要用到GD2 library
function make_thumb($src,$dest,$desired_width){ $source_image = imagecreatefromjpeg($src); $width = imagesx($source_image); $height = imagesy($source_image); $desired_height = floor($height*($desired_width/$width)); $virtual_image = imagecreatetruecolor($desired_width,$desired_height); imagecopyresized($virtual_image,$source_image,0,0,0,0,$desired_width,$desired_height,$width,$height); imagejpeg($virtual_image,$dest, 83);}希望本文所述对大家的php程序设计有所帮助。
