Copy file content to another file - php

Question

My file contains this content (1.txt):
user.php?id=XXXXXX
user.php?id=XXXXXX
user.php?id=XXXXXX
user.php?id=XXXXXX
user.php?id=XXXXXX
text/numbers
user.php?id=XXXXXX
user.php?id=XXXXXX
and so on ...
(XXXXXX = numbers)
It's possible to take only user.php?id=XXXXXX and copy them to another file, without coping unnecessary text because file contains about 50 000 lines ?

Answer 1

<?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);
?>
This code hasn't been tested, but I think it will work properly.

Answer 2

<?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 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 ...";
?>

Answer 4

suppose you want to copy the contents of "abc.php" file to "working_file.php"
place the following code in working_file.php , it will simply copy all the content.
<div>
<?php
$file = fopen("abc.php", "r") or die("Unable to open file!");
echo fread($myfile,filesize("abc.php"));
fclose($file);
?>
</div>
