[1]一些常用的php函数
    来源: 互联网  发布时间: 2013-11-30
1.产生随机字符串函数 

<?php 
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 



<?php 
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; 
} 
?>  



3.取得客户端IP地址 

<?php 
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); 
} 
?>  

4.创建相应的文件夹 



<?php 
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); 
                } 
            } 
        } 
} 
?>  


5.判断邮箱地址 



<?php 
function checkEmail($inAddress) 
{ 
 return (ereg("^([a-zA-Z0-9_-])+@([a-zA-Z0-9_-])+(\.[a-zA-Z0-9_-])+",$inAddress)); 
} 
?> 

6.跳转 



<?php 
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 >"; 
 $html .="<td>".$title."</td></tr>"; 
 $html .="<tr ><td align='center' height='60'>"; 
 $html .="<br>".$message."<br><br>"; 
    if (!empty($url)) 
     $html .="系统将在3秒后返回<br>如果您的浏览器不能自动返回,请点击[<a href="/blog_article/.$url" target=_self>这里</a>]进入"; 
    else 
     $html .="[<a href='#' onclick='history.go(-1)'>返回</a>]"; 
    $html .="</td></tr></table></td></tr></table>"; 
 $html .="</body></html>"; 
 echo $html; 
 exit; 
} 
?>  


7.分页（两个函数配合使用） 



<?php 
function getpage($sql,$page_size=20) 
 { 
      global $page,$totalpage,$sums;  //out param 
      $page = $_GET["page"]; 
      //$eachpage = $page_size; 
      $pagesql = strstr($sql," from "); 
      $pagesql = "select count(*) as ids ".$pagesql; 
      $result = mysql_query($pagesql); 
      if($rs = mysql_fetch_array($result)) $sums = $rs[0]; 
      $totalpage = ceil($sums/$page_size); 
      if((!$page)||($page<1)) $page=1; 
   $startpos = ($page-1)*$page_size; 
   $sql .=" limit $startpos,$page_size "; 
    return $sql; 
 } 

function showbar($string="") 
{      
    global $page,$totalpage; 
 $out="共<font color='red'><b>".$totalpage."</b></font>页  "; 
    $linkNum =4; 
    $start = ($page-round($linkNum/2))>0 ? ($page-round($linkNum/2)) : "1"; 
    $end   = ($page+round($linkNum/2))<$totalpage ? ($page+round($linkNum/2)) : $totalpage; 
    $prestart=$start-1; 
    $nextend=$end+1; 
    if($page<>1)  
 $out .= "<a href='/blog_article/page/1/amp;/amp;.html".$string."'title=第一页>第一页</a> "; 
    if($start>1) 
 $out.="<a href='/blog_article/page/.html".$prestart."' title=上一页>..<<</a> "; 
 for($t=$start;$t<=$end;$t++) 
    { 
     $out .= ($page==$t) ? "<font color='red'><b>[".$t."]</b></font> " : "<a href='/blog_article/page/$t/amp;/amp;.html".$string."'>$t</a> "; 
    } 
 if($end<$totalpage) 
 $out.="<a href='/blog_article/page/.html".$nextend."&&".$string."' title=下一页>>>..</a>"; 
    if($page<>$totalpage) 
   $out .= " <a href='/blog_article/page/.html".$totalpage."&&".$string."' title=最后页>最后页</a>"; 
   return $out; 
}
