php 目录列出所有文件

 在php中有很多方法来把目录所有文件列出的代码，用e
*/

$list = scandir(".");
    $zipname = "";
    foreach($list as $file)
    {
      if($file=="."||$file=="..")continue;
      $b=substr($file,-3);
      if($b==".gz"||$b==".fz")
      { $zipname = $file; break; }
    }
 
//代码二

$d=dir(".");
echo $d->path.$e;
while(false !== ($e= $d->read())) {
    echo "<a href=$e target=_blank >$e</a>"."<br>";
    }
$d->close();

//最简单的方法

$dirs    = array();
foreach(glob("test/*") as $d)
{
    if(is_dir($d))
    {
        $dirs[]    = $d;
    }
}
print_r($dirs);

//方法四

glob("test/*", glob_onlydir) ;

//方法五

function clean_dir($path)        {
        if (!is_dir($path))        {
                if (is_file($path))        {
                        unlink($path);
                }

        while ($f=readdir($p))        {
                if ($f=="." || $f=="..") continue;
                clean_dir($path.$f);
        }
        rmdir($path);

这里把数据库中的常用的内容保存到一个标准的php格式的文件当中，这样使用起来也方便了很多，下面代码。

$res=mysql教程_query("select k1,k2  from ".table('keywords')." ") ;
$str="<?php rn ";
while($rs=mysql_fetch_array($res))
{
 
 $str .="$keyword['".$rs[0]."']='".$rs[1]."';rn";
}
$str.="?>";
file_put_contents("keyword.php",$str);
echo "导出成功";

//方法二

$f=file_get_contents("w1.txt");
$f=str_replace("rn","<br>",$f);//替换换行符
$arr=explode("<br>",$f);
$str="<?php rn ";
foreach($arr as $t)
{
 $rs=explode("|",$t);
 //不能包含？等特殊符号
 $str .="$keyword['".str_replace("?","",$rs[0])."']='".str_replace("?","",$rs[1])."';rn";
 
}
$str.="?>";
file_put_contents("keyword.php",$str);
echo "导出成功";

//conn.php文件
$conn=mysql_connect($mysql_host,$mysql_user,$mysql_password) or die('连接服务器出错');
mysql_select_db($mysql_db) or die("选择数据库出错");
mysql_query("set names 'gbk'");
function table($t)
{
 global $mysql_table_prefix;
 return $mysql_table_prefix.$t;

这是一款老外写的mysql php接受数据过来然后进行数据保存在mysql_real_escape_string(nl2br(strip_tags($_POST[\'comment\'])));我觉得写得我们有一点区别吧。

代码如下
