PHP实现用正则替换Img中src地址参数

在实际开发过程,我们往往需要PHP动态的去改变图片参数去达到图片压缩,或者图片裁剪功能,但是已经入库的老图片代码,如何能解决裁剪和压缩,这就用到了正则替换

/** * 图片地址替换成压缩URL * @param string $content 内容 * @param string $suffix 后缀 */ function get_img_thumb_url($content="",$suffix="-256E35") { $pregRule = "/<[img|IMG].*?src=[\'|\"](.*?(?:[\.jpg|\.jpeg|\.png|\.gif|\.bmp]))[\'|\"].*?[\/]?>/"; $content = preg_replace($pregRule, '', $content); return $content; }
