獲取遠程文件抓取後的文件名

Question

我正在使用PHP文件抓取器腳本。我將遠程文件的URL放在字段​​上，然後將文件直接上傳到我的服務器。代碼如下所示：

<?php 
ini_set("memory_limit","2000M"); 
ini_set('max_execution_time',"2500"); 

foreach ($_POST['store'] as $value){ 
    if ($value!=""){ 
     echo("Attempting: ".$value."<br />"); 
     system("cd files && wget ".$value); 
     echo("<b>Success: ".$value."</b><br />"); 
    } 
} 

echo("Finished all file uploading."); 
?> 

上傳文件我想顯示直接鏈接到文件後：例如

完成了所有文件上傳，直接網址： http://site.com/files/grabbedfile.zip

你能幫我確定這段代碼中最後上傳文件的文件名嗎？

在此先感謝

您可以使用wget日誌文件。只需添加-o logfilename。
這裏是一個小function get_filename($wget_logfile)

ini_set("memory_limit","2000M"); 
ini_set('max_execution_time',"2500"); 

function get_filename($wget_logfile) 
{ 
    $log = explode("\n", file_get_contents($wget_logfile)); 
    foreach ($log as $line) 
    { 
     preg_match ("/^.*Saving to: .{1}(.*).{1}/", $line, $find); 
     if (count($find)) 
      return $find[1]; 
    } 
    return ""; 
} 

$tmplog = tempnam("/tmp", "wgetlog"); 
$filename = ""; 

foreach ($_POST['store'] as $value){ 
    if ($value!=""){ 
     echo("Attempting: ".$value."<br />"); 
     system("cd files && wget -o $tmplog ".$value); // -o logfile 

     $filename = get_filename($tmplog); // current filename 
     unlink ($tmplog); // remove logfile   

     echo("<b>Success: ".$value."</b><br />"); 
    } 
} 

echo("Finished all file uploading."); 
echo "Last file: ".$filename;

而是使用wget這樣的，你可以做到這一切使用捲曲，如果是可用的。

<?php 

set_time_limit(0); 

$lastDownloadFile = null; 
foreach ($_POST['store'] as $value) { 
    if ($value !== '' && downloadFile($value)) { 
     $lastDownloadFile = $value; 
    } 
} 

if ($lastDownloadFile !== null) { 
    // Print out info 
    $onlyfilename = pathinfo($lastDownloadFile, PATHINFO_BASENAME); 
} else { 
    // No files was successfully uploaded 
} 

function downloadFile($filetodownload) { 
    $fp = fopen(pathinfo($filetodownload, PATHINFO_BASENAME), 'w+'); 
    $ch = curl_init($filetodownload); 
    curl_setopt($ch, CURLOPT_TIMEOUT, 50); 
    curl_setopt($ch, CURLOPT_FILE, $fp); // We're writing to our file pointer we created earlier 
    curl_setopt($ch, CURLOPT_FOLLOWLOCATION, true); // Just in case the server throws us around 
    $success = curl_exec($ch); // gogo! 

    // clean up 
    curl_close($ch); 
    fclose($fp); 

    return $success; 
} 

一些謹慎的話讓人們上傳任何東西可能不是最好的主意。你想用這個完成什麼？
