PHP使用流类Stream读cUrl下载内容实例

<?php
$url = &#39;http://www.google.com.tw&#39; ;    
/* 建立接收的Temp File Stream */    
$tmpfile = tmpfile ();    
$curl = curl_init ();    
/* 指定下载的的URL */    
curl_setopt ( $curl , CURLOPT_URL, $url );     
/* 指定存放的File Stream */    
curl_setopt ( $curl , CURLOPT_FILE, $tmpfile );    
/* 执行并取得状态*/    
$status = curl_exec ( $curl );    
curl_close ( $curl );    
if (! $status ){     
   fclose ( $tmpfile );     
   exit ( &#39;error&#39; );     
}    
/* Temp File Stream 指标归零*/    
fseek ( $tmpfile , 0);    
/*一次读取一行*/    
while (( $line = fgets ( $tmpfile )) !== false ) {    
   var_dump ( $line );    
}    
/* 关闭Stream */    
fclose ( $tmpfile );
