1. php的網站，怎麼掃描出潛藏的一句話木馬

查找那些高危函數就行了，比如eval

php後門木馬常用的函數大致上可分為四種類型：

1. 執行系統命令: system, passthru, shell_exec, exec, popen,
proc_open
2. 代碼執行與加密: eval, assert, call_user_func,base64_decode, gzinflate,
gzuncompress, gzdecode, str_rot13
3. 文件包含與生成: require, require_once, include, include_once,
file_get_contents, file_put_contents, fputs, fwrite
4. .htaccess: SetHandler, auto_prepend_file, auto_append_file

3. php rpc好用嗎,有什麼優缺點php rpc框架哪個好

什麼是RPC框架？ 如果用一句話概括RPC就是：遠程調用框架（Remote Procere Call）那什麼是遠程調用？通常我們調用一個php中的方法，比如這樣一個函數方法: localAdd(10, 20)，localAdd方法的具體實現要麼是用戶自己定義的，要麼是php庫函數中自帶的，也就說在localAdd方法的代碼實現在本地，它是一個本地調用！遠程調用意思就是：被調用方法的具體實現不在程序運行本地，而是在別的某個遠程地方。

遠程調用原理

比如 A (client) 調用 B (server) 提供的remoteAdd方法：

4. jszip如何解壓字元串

其實php對gzip解壓很簡單，用內置的gzdecode函數就可以了，不過很可惜我配置了半天也無法支持gzdecode函數，所以只好變通一下： 復制代碼 代碼如下: if (!function_exists('gzdecode')) { function gzdecode ($data) { $flags = ord(substr($data, 3, 1)); $headerlen = 10; $extralen = 0; $filenamelen = 0; if ($flags & 4) { $extralen = unpack('v' ,substr($data, 10, 2)); $extralen = $extralen[1]; $headerlen += 2 + $extralen; } if ($flags & 8) // Filename $headerlen = strpos($data, chr(0), $headerlen) + 1; if ($flags & 16) // Comment $headerlen = strpos($data, chr(0), $headerlen) + 1; if ($flags & 2) // CRC at end of file $headerlen += 2; $unpacked = @gzinflate(substr($data, $headerlen)); if ($unpacked === FALSE) $unpacked = $data; return $unpacked; } } 調用方法很簡單： 復制代碼 代碼如下: $f=@file_get_contents(""); echo gzdecode($f);

5. 怎麼php發送get請求給java，然後返回想要的具體參數

curl請求java介面，介面返回值後進行相關操作，給你貼一個curl的代碼

functionihttp_request($url,$post='',$extra=array(),$timeout=60){
	$urlset=parse_url($url);
	if(empty($urlset['path'])){
		$urlset['path']='/';
	}

	}
	if(empty($urlset['port'])){

	}

6. PHP如何解碼Chunked+gzip獲得的源碼

我粘貼一下我的HTTP下載函數代碼，可以處理chunked編碼，我的程序裡面沒有GZIP編碼，如果你遇到GZIP，你在函數返回後再次進行解壓縮即可。

//執行HTTP請求
function http_request($url,$method='GET',$data='',$cookie='',$refer=''){
$header='';
$body='';
$newcookie='';
if (preg_match('/^http:\/\/(.*?)(\/.*)$/',$url,$reg)){$host=$reg[1]; $path=$reg[2];}
else {outs(1,"URL($url)格式非法!"); return;}
$http_host=$host;
if (preg_match('/^(.*):(\d+)$/', $host, $reg)) {$host=$reg[1]; $port=$reg[2];}
else $port=80;
$fp = fsockopen($host, $port, $errno, $errstr, 30);
if (!$fp) {
outs(1,"$errstr ($errno)\n");
} else {
fputs($fp, "$method $path HTTP/1.1\r\n");
fputs($fp, "Host: $http_host\r\n");
if ($refer!='') fputs($fp, "Referer: $refer\r\n");
if ($cookie!='') fputs($fp, "Cookie: $cookie\r\n");
fputs($fp, "Content-type: application/x-www-form-urlencoded\r\n");
fputs($fp, "Content-length: ".strlen($data)."\r\n");
fputs($fp, "Connection: close\r\n\r\n");
fputs($fp, $data . "\r\n\r\n");
$header_body=0;
$chunked_format=0;
$chunked_len=0;
while (!feof($fp)) {
$str=fgets($fp);
if ($header_body==1){
if ($chunked_format){
if ($chunked_len<=0){
$chunked_len=hexdec($str);
if ($chunked_len==0) break;
else continue;
} else {
$chunked_len-=strlen($str);
if ($chunked_len<=0) $str=trim($str);
}
}
$body.=$str;
}
else if ($str=="\r\n") $header_body=1;
else {
$header.=$str;
if ($str=="Transfer-Encoding: chunked\r\n") $chunked_format=1;
if (preg_match('|Set-Cookie: (\S+)=(\S+);|',$str,$reg)) $newcookie.=($newcookie==''?'':'; ').$reg[1].'='.$reg[2];
}
}
fclose($fp);
}
$GLOBALS['TRAFFIC']+=414+strlen($url)+strlen($data)+strlen($header)+strlen($body);
if (preg_match('/^Location: (\S+)\r\n/m',$header,$reg)) {
if (substr($reg[1],0,1)!='/'){
$path=substr($path,0,strrpos($path,'/')+1);
$path.=$reg[1];
} else $path=$reg[1];
if ($newcookie) $cookie=$newcookie;
return http_request('http://'.$http_host.$path,'GET','',$cookie,$url);
}
return array($body, $header, $newcookie);
}
