PHP只複製以字母結尾的文件AUW

Question

我有這個PHP代碼可以將文件從一個目錄複製到另一個目錄，但它的工作原理非常棒，但是，如何僅複製以字母「AUW」（減引號）結尾的文件？請記住，該文件是無擴展名的，所以它真的以字母AUW結尾。

複製後我不希望文件從源文件夾中刪除。

// Get array of all source files 
$files = scandir("sourcefolder"); 
// Identify directories 
$source = "sourcefolder/"; 
$destination = "destinationfolder/"; 
// Cycle through all source files 
foreach ($files as $file) { 
    if (in_array($file, array(".",".."))) continue; 
    // If we copied this successfully, mark it for deletion 
    if (copy($source.$file, $destination.$file)) { 
    $delete[] = $source.$file; 
    } 
} 
// Delete all successfully-copied files 
foreach ($delete as $file) { 
    unlink($file); 
} 

Answer 1

foreach ($files as $file) { 
    if (in_array($file, array(".",".."))) continue; 
    if (!endsWith($file, "AUW")) continue; 
    // If we copied this successfully, mark it for deletion 
    if (copy($source.$file, $destination.$file)) { 
    // comment the following line will not add the files to the delete array and they will 
    // not be deleted 
    // $delete[] = $source.$file; 
    } 
} 

// comment the followig line of code since we dont want to delete 
// anything 
// foreach ($delete as $file) { 
// unlink($file); 
// } 

function endsWith($haystack, $needle) 
{ 
    $length = strlen($needle); 
    if ($length == 0) return true; 

    return (substr($haystack, -$length) === $needle); 
}

Google搜索太難了嗎？ 我給你一個提示 - 使用substr()，看看最後的3個字母是「AUW」

Answer 3

你可以使用函數glob。

foreach (glob("*AUW") as $filename) { 
    // do the work... 
} 

Answer 4

您想使用glob函數。

foreach(glob("*.AUW") as $filename) 
{ 
     echo $filename; 
}

使用substr() method搶到最後三個文件名的字母。這將返回一個可用於邏輯比較的字符串。

if(substr($file, -3) == 'AUW') 
{ 
    // Process files according to your exception. 
} 
else 
{ 
    // If we copied this successfully, mark it for deletion 
    if (copy($source.$file, $destination.$file)) { 
    $delete[] = $source.$file; 
}
