由于emlog6.0.1是老司机修改版  所以肯定是跟着他的节奏走的！就比如今天有人遇到了个问题 就是刷新文章不增加浏览次数  然后 我也看了了  还真是最后我看了下文件  发现了 这么个玩意 哪个应该是判断登入状态的   然后我已游客的浏览方式尝试刷新看看有没有增加 最后还真是这的问题之所以刷新不增加浏览次数的原因就在这里  最后修改方法也很简单 就是去掉判断即可大家参考下图删掉 301行和303行 即可文件在/include/model/log_model.php最后告诉大家个小秘诀  刷新一次+5views=views+1  中的1改成任意数字就行了

获取文件后缀的方法有很多种，差不多能总结出7,8种，原理基本上都分成两种。第一种：得到文件名中最后一个“.”的位置，然后再进行截取；第二种：用explode将文件名以“.”进行分割成数组，再取数组中最后一个值。具体实现源码参考：$file1 = 'e:/ddd/ww/file.doc.zip';$file2 = 'e:/ddd/ww/file.jpg.png';$suffix1 = end( explode('.', $file1) );//先把文件名以“.”分割成数组，再用end函数取数组最后一个值$suffix2 = substr( $file2, strrpos($file2, '.')+1 );//strrpos先计算出最后一个“.”的位置，再用substr截取echo $suffix1.'-'.$suffix2;
