I am having a problem saving a file using fopen. For some reason the saved file has a question mark in the end.
I am attempting to retrieve a list of files from a remote server and download them to my server.
This is the part of my code that does the job :
$arrlength = count($reports);
for ($x = 0; $x < $arrlength; ++$x) {
$report = $reports[$x];
$thefilepath = returnfilename($report);
echo 'the filepath : '.$thefilepath;
echo '<br>';
$thefilename = basename($thefilepath).PHP_EOL;
echo 'the filename : '.$thefilename;
echo '<br>';
$localfile = 'incoming/'.$thefilename;
echo 'local file to save : '.$localfile;
echo '<br>';
curl_setopt($ch, CURLOPT_URL, $thefilepath);
$out = curl_exec($ch);
$fp = fopen($localfile, 'w');
fwrite($fp, $out);
fclose($fp);
}
This script returns the following (I've hidden the actual addresses - retain the spaces etc):
the filepath : https://example.com.com/xxx/xxx.xlsx
the filename : xxx.xlsx
local file to save : incoming/xxx.xlsx
When on my server I do a ls I get :
-rw-r--r-- 1 www-data www-data 29408 May 17 23:01 xxx.xlsx?
There is nothing wrong with the file, when I remove the ? I can retrieve it as normal and open it.
What is this? And how can I do it so it is not added in the end?
The string you're using to name the file has a non-printable character at the end, and ls is telling you that there is something there, even if you would normally be unable to see it. Strip the character from the string before using it.

Hi I want to download some 250 files from a URL which are in a sequence. I am almost done with it! Just the Problem is the structure of my URL is:
http://lee.kias.re.kr/~newton/sann/out/201409//SEQUENCE1.prsa
Where id is in a sequence but the file name "SEQUENCE1.psra" has a format "SEQUENCE?.psra".
Is there any way I can specify this format of file in my code? And also there are other files in folder, but only 1 with ".psra" ext.
Code:
<?php
// Source URL pattern
//$sourceURLOriginal = "http://www.somewebsite.com/document{x}.pdf";
$sourceURLOriginal = " http://lee.kias.re.kr/~newton/sann/out/201409/{x}/**SEQUENCE?.prsa**";
// Destination folder
$destinationFolder = "C:\\Users\\hp\\Downloads\\SOP\\ppi\\RSAdata";
// Destination file name pattern
$destinationFileNameOriginal = "doc{x}.txt";
// Start number
$start = 7043;
// End number
$end = 7045;
$n=1;
// From start to end
for ($i=$start; $i<=$end; $i++) {
// Replace source URL parameter with number
$sourceURL = str_replace("{x}", $i, $sourceURLOriginal);
// Destination file name
$destinationFile = $destinationFolder . "\\" .
str_replace("{x}", $i, $destinationFileNameOriginal);
// Read from URL, write to file
file_put_contents($destinationFile,
file_get_contents($sourceURL)
);
// Output progress
echo "File #$i complete\n";
}
?>
Its working if I directly specify the URL!
Error:
Warning: file_get_contents( http://lee.kias.re.kr/~newton/sann/out/201409/7043/SEQUENCE?.prsa): failed to open stream: Invalid argument in C:\xampp\htdocs\SOP\download.php on line 37
File #7043 complete
Its making the files but they are empty!
If there is a way in which I can download that whole folder(named with id in sequence) can also work! But how do we download the whole folder in a folder?
It may be possible file_get_contents() function is not working on your server.
Try this code :
function url_get_contents ($Url) {
if (!function_exists('curl_init')){
die('CURL is not installed!');
}
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $Url);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
$output = curl_exec($ch);
curl_close($ch);
return $output;
}
Here you go.
I didnt test the whole file_get_contents, file_put_contents part, but if you say its adding the files (albeit, blank) then I assume it still works here...
Everything else works fine. I left a var_dump() in so you can see what the return looks like.
I did what I suggested in my comment. Open the folder, parse the file list, grab the filename you need.
Also, I dont know if you read my original comments, but $sourceURLOriginal has an extra space at the beginning, which might have been giving you an issue.
<?php
$start=7043;
$end=7045;
$sourceURLOriginal="http://lee.kias.re.kr/~newton/sann/out/201409/";
$destinationFolder='C:\Users\hp\Downloads\SOP\ppi\RSAdata';
for ($i=$start; $i<=$end; $i++) {
$contents=file_get_contents($sourceURLOriginal.$i);
preg_match_All("|href=[\"'](.*?)[\"']|",$contents,$hrefs);
$file_list=array();
if (empty($hrefs[1])) continue;
unset($hrefs[1][0],$hrefs[1][1],$hrefs[1][2],$hrefs[1][3],$hrefs[1][4]);
$file_list=array_values($hrefs[1]);
var_dump($file_list);
foreach ($file_list as $index=>$file) {
if (strpos($file,'prsa')!==false) {
$needed_file=$index;
break;
}
}
file_put_contents($destinationFolder.'\doc'.$i.'.txt',
file_get_contents($sourceURLOriginal.$i.'/'.$file_list[$needed_file])
);
}
I have a list of URL's I would like to clean back to their root domain (and sub domains), so far I have this which is fairly simple and works how I need it to:
echo parse_url('https://app.ffgx.com/fdgdfg', PHP_URL_HOST) . '<br />';
echo parse_url('https://www.fgigo.com/fgdfg', PHP_URL_HOST) . '<br />';
However I have a large list of over 200 URL's, so adding each URL like this will be very time consuming.
My question is, how can I upload this script to my server and include an upload button which will allow me to upload a list of URL's in txt or csv format; it will then run through the list and present me with all the stripped URL's?
Something like this with txt file. Where inputfile.txt contains your url's that should be 1 in a line.
https://app.ffgx.com/fdgdfg
https://www.ffgx.com/fdgdfg
Then Store all the extracted domain in array, $url_list. Then depend on you what you will do with array data.
$url_list = array();
$handle = #fopen("/path/inputfile.txt", "r");
if ($handle) {
while (($buffer = fgets($handle, 4096)) !== false) {
$url_list[] = parse_url($buffer, PHP_URL_HOST);
}
if (!feof($handle)) {
echo "Error: unexpected fgets() fail\n";
}
fclose($handle);
}
If your URL's in the file will only be starting with "https" or "http", then you read the text file and by using str_replace(), all the url's can be removed / replaced. And then again you can write the new replaced content into the file.
I have been trying for a few hours now to no avail. I have successfully output my CSV as a download in the browser using:
header("Content-type: application/csv");
header("Content-Disposition: attachment; filename=".$csv_filename."");
However I want that output to now go to an FTP server instead, I have got the connection and temp file part sorted but cannot seem to edit the file to output my results.
// create empty variable to be filled with export data
$csv_export = '';
for($i = 0; $i < $field; $i++) {
$csv_export.= mysql_field_name($query,$i).',';
}
// newline (seems to work both on Linux & Windows servers)
$csv_export.= '
';
// loop through database query and fill export variable
while($row = mysql_fetch_array($query)) {
// create line with field values
for($i = 0; $i < $field; $i++) {
$csv_export.= '"'.$row[mysql_field_name($query,$i)].'",';
}
$csv_export.= '
';
}
Above is the part that gets the query data and puts it into the CSV, I have tried incorporating both fputs and fputcsv in the loops to write the rows to the file.
//Upload the temporary file to server
ftp_fput($ftpstream, '/httpdocs/.../abandoned.csv', $temp, FTP_ASCII);
$fp = fopen('var/www/vhosts/.../abandoned.csv', 'w');
fputs($fp, '$csv_export');
fclose($fp);
echo($csv_export);
So, echoing the output works absolutely fine - all I want is that echo'd data written into a CSV file and uploaded to the FTP.
The error I've been given is:
Array ( [type] => 2 [message] => fclose() expects parameter 1 to be resource,
boolean given
So the fp is causing the problem... is it at the open stage or at the writing of csv_export?
Thanks in advance.
Try this
//Write the contents to the temp file
fputs($temp, $csv_export);
//upload the temp file
ftp_fput($ftpstream, '/httpdocs/.../abandoned.csv', $temp, FTP_ASCII);
//close the temp file
fclose($temp);
Your current code is creating an empty file, uploading it, and then creating a separate file. Even if you get it working on a local server, it is an unnecessary step.
Try this, not tested:
$filename = 'abandoned.csv';
$content = $csv_export;
$host = 'yourhost';
$user = 'youruser';
$password = 'yourpass';
//open connection to your ftp server
$stream = stream_context_create(array('ftp' => array('overwrite' => true)));
//authenticate to your ftp server, normal uri syntax
$uri = sprintf('ftp://%s:%s#%s/%s', $user, $password, $host, $filename);
file_put_contents($uri, $content, 0, $stream);
In phpinfo(); you can look for Registered PHP Streams and just use this in most of any cases:
file_put_contents('ftp://user:password#server/your/directory/file.csv', $csvData);
ftp_fput is a right way here.
But you have to prepare FTP connection and authenticate first. Assuming you have $csv_export string in memory:
// connect
$ftp_conn = ftp_connect('ftp.yourserver.net');
// authenticate
$login_result = ftp_login($conn_id, 'ftp_username', 'password');
// prepare output stream
$stream = fopen('data://text/plain,' . $csv_export, 'r');
// try to upload
if (ftp_fput($ftp_conn, '/httpdocs/.../abandoned.csv', $stream, FTP_ASCII)) {
echo "Successfully uploaded\n";
} else {
echo "There was a problem while uploading\n";
}
// close the connection and the file handler
ftp_close($ftp_conn);
fclose($stream);
You're receiving that error because fopen is returning false, which indicates that it was unable to open the file.
If I'm understanding your code, you're uploading abandoned.csv (which presumably exists) to the ftp after opening it in $temp. Is $temp pointing at your local copy of abandon.csv? Because if so, you should close the file stream pointing to it before opening a second one with fopen.
If that's not the issue, then abandoned.csv may not actually exist, in which case you may just be trying to fopen a missing file.
I'm testing php because I'm a freshman in this matter. I put my php code in a free server, they let me do my own index.php, manage some php variables (like register_globals, magic_quotes_gpc etc. I left them as default), but apparently I can handle not more than one file in a php code, for example:
<?php
//--------Updating Data-------------
$cdc = intval($_POST['cantidadDeCapitulos']);
$toWrite = array('ctot' => $cdc);
for($i=1;$i<$cdc+1;$i += 1){
$toWrite["cap".$i] = $_POST['numdeCap'.$i];
}//---------------------------------
$datos = file_get_contents("myfile.json.");
$toWrite = json_encode( $toWrite );
//Open a file in write mode
$fp = fopen("myfile2.json", "w");
if(fwrite($fp, "$toWrite")) {
echo "&verify=success&";
} else {
echo "&verify=fail&";
}
fclose($fp);
?>
If I comment out the line $datos = file_get_contents("myfile.json."); it's alright!, something is written in myfile2.json but if it is uncommented, the data is not updated. Both files have permission 666 and they are in the same directory i.e., /root.
$datos = file_get_contents("myfile.json.");
Seems like a typo has occurred. Take off the final dot from your file. I mean, change the line to:
$datos = file_get_contents("myfile.json");
try this:
<?php
$file = 'myfile.json';
// Open the file to get existing content
$current = file_get_contents($file);
// Write the contents back to the file
file_put_contents($file, $current);
?>
I have searched the web for 2 days and can not find the answer.
I am trying to create a routine which displays the files on a site I control, and allows the user to download a selected file to a local drive.
I am using the code below. When I uncomment the echo statements, it displays the correct source and destination directories, the correct file size and the echo after the fclose displays TRUE.
When I echo the source file ($data), it displays the correct content.
The $FileName variable contains the correct filename, which is either .doc/.docx or .pdf. I have tested both and neither saves anything into the destination directory, or anywhere else on my machine.
The source path ($path) is behind a login, but I am already logged in.
Any thoughts on why this is failing to write the file?
Thanks,
Hank
Code:
$path = "https://.../Reports/ReportDetails/$FileName";
/* echo "Downloading: $path"; */
$data = file_get_contents($path); /* echo "$data"; */
$dest = "C:\MyScans\\".$FileName; /* echo "<br />$dest"; */
$fp = fopen($dest,'wb');
if ( $fp === FALSE ) echo "<br />Error in fopen";
$result = fwrite($fp,$data);
if ( $result === FALSE ) echo "<br />Can not write to $dest";
/* else echo "<br />$result bytes written"; */
$result = fclose($fp); /* echo "<br />Close: $result"; */
I think (!) that you're a bit confused.
You mentioned
allows the user to download a selected file to a local drive.
But the path "C:\MyScans\\".$FileName is is the path on the webserver, not the path on the user's own computer.
After you do whatever to retrieve the desired file from the remote website:
Create a file from it and redirect the user to the file by using header('Location: /path/to/file.txt');
Insert the following header:
header('Content-disposition: attachment; filename=path/to/file.txt');
It forces the user to download the file. And that's probably what you want to do
Note: I have used the extension txt, but you can use any extension
you can use php Curl:
<?php
$url = 'http://www.example.com/a-large-file.zip';
$path = '/path/to/a-large-file.zip';
$fp = fopen($path, 'w');
$ch = curl_init($url);
curl_setopt($ch, CURLOPT_FILE, $fp);
$data = curl_exec($ch);
curl_close($ch);
fclose($fp);
