複製文件內容到另一個文件

Question

我的文件中包含該內容（的1.txt）：

• user.php的ID = XXXXXX
• user.php的ID = XXXXXX
• user.php的？ ID = XXXXXX
• user.php的？ID = XXXXXX
• user.php的？ID = XXXXXX
• 文/數字
• user.php的？ID = XXXXXX
• user.php的？ID = XXXXXX
• 等等...

（XXXXXX =數字）

有可能只採取user.php的？ID = XXXXXX，並將它們複製到另一個文件，而不處理不必要的文本，因爲文件包含大約50 000行？

Answer 1

<?php 
    //Get all the matches from the file 
    $fileContents = file_get_contents('1.txt'); 
    preg_match_all('/user.php\?id=[0-9]{6}/', $fileContents, $matches); 

    //Output to new file 
    $fh = fopen('output.txt', 'w+'); 
    foreach ($matches['0'] as $match) { 
     fputs($fh, $match."\r\n"); 
    } 
    fclose($fh); 
?> 

Answer 2

<?php 
    $file = fopen('source.txt', 'rb'); 
    $newfile = fopen('target.txt', 'wb'); 
    while(($line = fgets($file)) !== false) { 
    if(strpos($line, 'user.php') !== false) { 
     fputs($newfile, $line); 
    } 
    } 
    fclose($newfile); 
    fclose($file); 
    ?> 

此代碼尚未經過測試，但我認爲這將正常工作。

Answer 3

<?php 
error_reporting(0); 
$fs=fopen("1.txt", "r"); 
$ft=fopen("2.txt", "w"); 

if ($fs==NULL) 
{ 
    echo "Can't Open Source File ..."; 
    exit(0); 
} 

if ($ft==NULL) 
{ 
    echo "Can't Open Destination File ..."; 
    fclose ($fs); 
    exit(1); 
} 

else 
{ 
    while ($ch=fgets($fs)) 
     fputs($ft, $ch); 

    fclose ($fs); 
    fclose ($ft); 
} 

//echo "File Handling successfully ..."; 
?>
