使用php列出日志文件

写本文目的主要是基于没有服务器登陆权限，项目发布到测试站或正式站之后，无法查看代码中记录的错误信息日志，此时需要一个脚本显示服务器上记录的日志信息，准备两个方法如下：（样式可自行调节）

//判断是打开、查看、下载function show ($dir_base, $req_path) {    if(!empty($req_path)) {        $path = $dir_base.$req_path;        if(is_dir($path)) {            header("Content-type: text/html; charset=utf-8");            list_dir($path, $dir_base);        }elseif(is_file($path)) {            if($_REQUEST['type'] == 'download') {                header("Content-Type: application/force-download");                header("Content-Disposition: attachment; filename=".basename($path));                readfile($path);            }elseif($_REQUEST['type'] == 'show') {                header('Content-Type: text/plain; charset=utf-8');                header("filename=".basename($path));                $ret = readfile($path);                exit();            }        }    }else {        if(!is_dir($dir_base)) {            echo "\"$dir_base\""." is not a directory!";            exit;        }        header("Content-type: text/html; charset=utf-8");        list_dir($dir_base, $dir_base);    }}

//列出目录或文件function list_dir ($path, $base) {    $arr = scandir($path);    foreach($arr as $val) {        $full_path = $path."/".$val;        $href= str_replace($base, '', $full_path);        if(is_dir($full_path)) {            if($val == '.') {                continue;            }            if($val == '..' && $path == $base) {                continue;            }elseif($val == '..') {                $last= dirname($path);                $href= str_replace($base, '', $last);            }            echo '<a style="color:#1a9d17;font-weight:bold;text-decoration: none;" href="'.basename(__FILE__).'?path='.$href.'">'.$val.'</a><br/>';        }elseif(is_file($full_path)) {            echo $val."   ";            echo '<a style="color:#1B97CA;text-decoration: none;" target="_blank" href="'.basename(__FILE__).'?path='.$href.'&type=show">在线查看</a>   ';            echo '<a style="color:#1B97CA;text-decoration: none;" href="'.basename(__FILE__).'?path='.$href.'&type=download">下载</a>   ';            $filesize = filesize($full_path);            if($filesize >=1024000){                $filesize = sprintf("%0.2f", ($filesize/1024/1024)) . "MB";            }elseif($filesize >= 1024) {                $filesize = sprintf("%0.2f", ($filesize/1024))."KB";            }else {                $filesize .= "B";            }            echo "{$filesize}<br/>";        }    }}

调用方式如下：

$req_path = $_REQUEST['path'];show('/log',$req_path);
