TP获得mysql版本及mysql数据库大小<?php <br />
namespace Admin\Controller;<br>
use Think\Controller;<br>
class SystemController extends AdminController<br>
{<br>
protected function _model(){<br>
return new \Think\Model();<br>
}<br>
<br>
public function indexAction()<br>
{<br>
layout( true );<br>
$this->sysinfo = array(<br>
'os' => $_SERVER["SERVER_SOFTWARE"], //获取服务器标识的字串<br>
'version' => PHP_VERSION, //获取PHP服务器版本<br>
'time' => date("Y-m-d H:i:s", time()), //获取服务器时间<br>
'pc' => $_SERVER['SERVER_NAME'], //当前主机名<br>
'osname' => php_uname(), //获取系统类型及版本号<br>
'language' => $_SERVER['HTTP_ACCEPT_LANGUAGE'], //获取服务器语言<br>
'port' => $_SERVER['SERVER_PORT'], //获取服务器Web端口<br>
'max_upload' => ini_get("file_uploads") ? ini_get("upload_max_filesize") : "Disabled", //最大上传<br>
'max_ex_time' => ini_get("max_execution_time")."秒", //脚本最大执行时间<br>
'mysql_version' => $this->_mysql_version(),<br>
'mysql_size' => $this->_mysql_db_size(),<br>
);<br>
$this->display();<br>
}<br>
<br>
private function _mysql_version()<br>
{<br>
$Model = self::_model();<br>
$version = $Model->query("select version() as ver");<br>
return $version[0]['ver'];<br>
}<br>
<br>
private function _mysql_db_size()<br>
{ <br>
$Model = self::_model();<br>
$sql = "SHOW TABLE STATUS FROM ".C('DB_NAME');<br>
$tblPrefix = C('DB_PREFIX');<br>
if($tblPrefix != null) {<br>
$sql .= " LIKE '{$tblPrefix}%'";<br>
}<br>
$row = $Model->query($sql);<br>
$size = 0;<br>
foreach($row as $value) {<br>
$size += $value["Data_length"] + $value["Index_length"];<br>
}<br>
return round(($size/1048576),2).'M';<br>
}<br>
}不足之处望指点！http://www.yi210.com/archives/919.html
