1.取得LINUX服务器的空间大小disk_free_space 剩余空间disk_total_space 总空间.2.PHP可以获得客户端操作系统的信息$_SERVER['ACCEPT_LANGUAGE']
.产生随机字符串函数
function random($length) { $hash = @#@#; $chars = @#ABCDEFGHIJKLMNOPQRSTUVWXYZ0123456789abcdefghijklmnopqrstuvwxyz@#; $max = strlen($chars) - 1; mt_srand((double)microtime() * 1000000); for($i = 0; $i < $length; $i++) { $hash .= $chars[mt_rand(0, $max)]; } return $hash; } 2.截取一定长度的字符串 注：该函数对GB2312使用有效function wordscut($string, $length ,$sss=0) { if(strlen($string) > $length) { if($sss){ $length=$length - 3; $addstr=@# ...@#; } for($i = 0; $i < $length; $i++) { if(ord($string[$i]) > 127) { $wordscut .= $string[$i].$string[$i + 1]; $i++; } else { $wordscut .= $string[$i]; } } return $wordscut.$addstr; } return $string; }
取得客户端IP地址 function GetIP(){ if (getenv("HTTP_CLIENT_IP") && strcasecmp(getenv("HTTP_CLIENT_IP"), "unknown")) $ip = getenv("HTTP_CLIENT_IP"); else if (getenv("HTTP_X_FORWARDED_FOR") && strcasecmp(getenv("HTTP_X_FORWARDED_FOR"), "unknown")) $ip = getenv("HTTP_X_FORWARDED_FOR"); else if (getenv("REMOTE_ADDR") && strcasecmp(getenv("REMOTE_ADDR"), "unknown")) $ip = getenv("REMOTE_ADDR"); else if (isset($_SERVER[@#REMOTE_ADDR@#]) && $_SERVER[@#REMOTE_ADDR@#] && strcasecmp($_SERVER[@#REMOTE_ADDR@#], "unknown")) $ip = $_SERVER[@#REMOTE_ADDR@#]; else $ip = "unknown"; return($ip); }
创建相应的文件 夹 function createdir($dir=@#@#) { if (!is_dir($dir)) { $temp = explode(@#/@#,$dir); $cur_dir = @#@#; for($i=0;$i<count($temp);$i++) { $cur_dir .= $temp[$i].@#/@#; if (!is_dir($cur_dir)) { @mkdir($cur_dir,0777); } } } } 判断邮箱地址 function checkEmail($inAddress) { return (ereg("^([a-zA-Z0-9_-])+@([a-zA-Z0-9_-])+(.[a-zA-Z0-9_-])+",$inAddress)); }
跳转
function gotourl($message=@#@#,$url=@#@#,$title=@#@#) { $html ="<html><head>"; if(!empty($url)) $html .="<meta http-equiv=@#refresh@# content="3;url=@#".$url."@#">"; $html .="<link href=@#../templates/style.css@# type=text/css rel=stylesheet>"; $html .="</head><body><br><br><br><br>"; $html .="<table cellspacing=@#0@# cellpadding=@#0@# border=@#1@# width=@#450@# align=@#center@#>"; $html .="<tr><td bgcolor=@##ffffff@#>"; $html .="<table border=@#1@# cellspacing=@#1@# cellpadding=@#4@# width=@#100%@#>"; $html .="<tr class=@#m_title@#>"; $html .="<td>".$title."</td></tr>"; $html .="<tr class=@#line_1@#><td align=@#center@# height=@#60@#>"; $html .="<br>".$message."<br><br>"; if (!empty($url)) $html .="系统将在3秒后返回<br>如果您的浏览器不能自动返回,请点击[<a href=".$url." target=_self>这里</a>]进入"; else $html .="[<a href=@##@# οnclick=@#history.go(-1)@#>返回</a>]"; $html .="</td></tr></table></td></tr></table>"; $html .="</body></html>"; echo $html; exit; }
