running php on ubuntu through shell - unlink & fopen always fail - php

I am trying to delete an xml file, and then re-create it with data from an xml feed using cURL.
my PHP code is as follows:
function get_file($file, $local_path, $newfilename){
//Delete old xml file first
unlink('../../xml/file.xml');
// Create a new one
$out = fopen($local_path.$newfilename,"wb");
if ($out == FALSE){
print "<br>File not opened<br>";
exit;
}
$ch = curl_init();
// Setup options, where to write etc
curl_setopt($ch, CURLOPT_FILE, $out);
curl_setopt($ch, CURLOPT_HEADER, 0);
curl_setopt($ch, CURLOPT_CONNECTTIMEOUT, 0);
curl_setopt($ch, CURLOPT_TIMEOUT, 28800);
curl_setopt($ch, CURLOPT_URL, $file);
// Execute
curl_exec($ch);
// Close
curl_close($ch);
}
// get_file(url_of_file, directory_to_put, filename);
get_file('XML FEED URL', '../../xml/', 'file.xml');
this code used to work fine until I moved to an Ubuntu virtual server.
I want to use the code by running the following command:
php ../var/www/html/php/cron/download_xml_feed.php
the xml folder (and current xml file) are located at ../var/www/html/xml
Every time I run the command however it gives me:
PHP Warning: unlink(../../xml/jobs.xml): No such file or directory in /var/www/html/php/cron/download_xml_feed.php on line 7
PHP Warning: fopen(../../xml/jobs.xml): failed to open stream: No such file or directory in /var/www/html/php/cron/download_xml_feed.php on line 10
this will eventually be a crontab run with the above command
How can I get it to work?

How to upload file from local to server using curl in php?

I want to upload the file from local to server using curl in php and without using the form (which is html).
My php version is 5.2.6.
I have tried many different way and make many research about (upload file to server using curl in php), but the solution in google cannot solve my problem.
Below is my code:
// open file descriptor
$fp = fopen ("user.com/user/fromLocal.txt", 'w+') or die('Unable to write a file');
// file to download
$ch = curl_init('C:/wamp/www/user/fromLocal.txt');
// enable SSL if needed
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);
// output to file descriptor
curl_setopt($ch, CURLOPT_FILE, $fp);
curl_setopt($ch, CURLOPT_FOLLOWLOCATION, TRUE);
// set large timeout to allow curl to run for a longer time
curl_setopt($ch, CURLOPT_TIMEOUT, 1000);
curl_setopt($ch, CURLOPT_USERAGENT, 'any');
// Enable debug output
curl_setopt($ch, CURLOPT_VERBOSE, true);
echo $ch;
echo $fp;
curl_exec($ch);
curl_close($ch);
fclose($fp);
Expected output:
The file can upload to server and view.
Actual output:
Unable to write the file
I think you miss important information.
fopen ("user.com/user/fromLocal.txt", 'w+')
this means nothing.
To send a file to the server the server has to be configured to accept a POST request and you have to send the file through that endpoint.
If you have a form, do you send it to: "user.com/user/fromLocal.txt" ??
You have to create the form data with curl and send it to a server ready to accept your request. There are different ways to accomplish that. And the most simple is exactly to send a form using curl and not the HTML. But absolutly you cannot write a file like that in a server.

cURL and PHP issue

So far I want a curl command to download a file into a specific directory , So I have done this
system('curl -o hi.txt www.site.com/hi.html');
It doesn't work because my directory isn't writable , I need to find a way to set curl to download that file to a writable directory of mine .
Instead of curl you could use file_get_contents and file_put_contents
$file = file_get_contents('http://www.site.com/hi.html');
file_put_contents('/htdocs/mysite/images/hi.txt', $file);
This method will work even if the curl module isn't installed. To do this using cURL (which will allow more control over the actual http request):
// create a new cURL resource
$ch = curl_init();
// set URL and other appropriate options
curl_setopt($ch, CURLOPT_URL, "http://www.site.com/hi.html");
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($ch, CURLOPT_HEADER, 0);
// grab URL and pass it to the browser
$out = curl_exec($ch);
// close cURL resource, and free up system resources
curl_close($ch);
// Save the file
$fp = fopen('/htdocs/mysite/images/hi.txt', 'w');
fwrite($fp, $out);
fclose($fp);
EDIT
system('curl -o /htdocs/mysite/images/hi.txt www.site.com/hi.html');

File Download not Saving into Downloads Folder

I wish to download files from my web server with download progress information. For that purpose, PHP cURL seems to be the best choice.
However, I have difficulties that the downloaded files are not placed into Downloads folder, where all the web files are normally downloaded. I use the following file download routine:
$fp = fopen(dirname(__FILE__) . 'uploaded.pdf', 'w+');
$url = "file:///D:/WEB/SAIFA/WWW/PickUpTest.pdf";
$ch = curl_init(str_replace(" ","%20", $url));
curl_setopt($ch, CURLOPT_HEADER, 0);
curl_setopt($ch, CURLOPT_USERAGENT, 'Mozilla/5.0 (Windows NT 6.1; rv:2.0.1) Gecko/20100101 Firefox/4.0.1');
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_BINARYTRANSFER, true);
curl_setopt($ch, CURLOPT_FOLLOWLOCATION, true);
curl_setopt($ch, CURLOPT_BUFFERSIZE, 1024*8);
curl_setopt($ch, CURLOPT_NOPROGRESS, false );
curl_setopt($ch, CURLOPT_PROGRESSFUNCTION, 'progressCallback' );
curl_setopt($ch, CURLOPT_CONNECTTIMEOUT, 0);
curl_setopt( $ch, CURLOPT_FILE, $fp );
curl_exec( $ch );
curl_close($ch);
fclose($fp);
unset($fp);
My problem is, that instead Downloads folder, the file is silently downloaded into my WWW folder, where the my PHP scripts including this cURL one reside. I get no File Download Save As dialog box neither.
To force Save As dialog box, I added the following header, at the beginning of the script:
header("Content-Disposition: attachment; filename=\"uploaded.pdf\"");
$fp = fopen(dirname(__FILE__) . 'uploaded.pdf', 'w+');
...
After using the header, I get the Save As dialog box however, the file is still silently download into the folder with my PHP scripts. In the Downloads folder, a file 'uploaded.pdf' with filesize 0 is saved.
My question is, how to make PHP cURL to download files properly and place them into Downloads folder and offer Save As dialog box?
I use:
WAMP
Windows 7
PHP Version 5.4.12
Curl Version 7.29.0
By using the file functions you're actually asking your server to save the file so it makes sense that the results of the cURL call end up in your PHP folder.
What you really want, if I understand the problem, is to send the results of the cURL back to the browser. You're halfway there by sending the header(...) - which lets the user's browser know a file is coming and should be downloaded, the step you've missed is sending the cURL data with the header.
You could echo the contents of the file after you've saved it or, more efficiently (assuming you don't want an extra copy of the file), remove the code to save the file locally and remove the cURL option CURLOPT_RETURNTRANSFER. That will tell cURL to send the output directly so it will become the data for the download.
Hope that helps!
EDIT A simple example that grabs a local file (C:\test.pdf) and sends it to the user's browser (as uploaded.pdf).
<?php
header("Content-Disposition: attachment; filename=\"uploaded.pdf\"");
// Get a FILE url to my test document
$url = 'file://c:/test.pdf';
$url= str_replace(" ","%20", $url);
$ch= curl_init();
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_BINARYTRANSFER, true);
curl_exec( $ch );
curl_close ($ch);
Hope that helps a bit more!

Bast way to move file from server to server in PHP

I have sites where stored some xml files, and I want to download to our server, we don't have ftp connection, so we can download through http. I always used file(url) is there any better way to download files through php
If you can access them via http, file() (which reads the file into an array) and file_get_contents() (which reads content into a string) are perfectly fine provided that the wrappers are enabled.
Using CURL could also be a nice option:
// create a new CURL resource
$ch = curl_init();
// set URL and other appropriate options
curl_setopt($ch, CURLOPT_URL, "http://www.server.com/file.zip");
curl_setopt($ch, CURLOPT_HEADER, false);
curl_setopt($ch, CURLOPT_BINARYTRANSFER, true);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
set_time_limit(300); # 5 minutes for PHP
curl_setopt($ch, CURLOPT_TIMEOUT, 300); # and also for CURL
$outfile = fopen('/mysite/file.zip', 'wb');
curl_setopt($ch, CURLOPT_FILE, $outfile);
// grab file from URL
curl_exec($ch);
fclose($outfile);
// close CURL resource, and free up system resources
curl_close($ch);

How to write verbose information into file?

I'm using CURL in my php script and I want to write information from CURLOPT_VERBOSE into file. I tried CURLOPT_STDERR but without luck. It still print everything in cmd window. I'm not sure if parameter in curl_setopt($ch, CURLOPT_STDERR, $errFileHandle); should be file handler or file name (both not work).
Running on a Unix based OS? Use the below on the command line to run your script. Using Windows OS, use the command on Cygwin.
php yourPhp.php > yourFile.txt
Or you can just run it in verbose mode with a file handle
<?PHP
$verbosPath = __DIR__.DIRECTORY_SEPARATOR.'verboseOut.txt';
echo "Saving verbose output to: $verbosPath\n";
$handle=curl_init('http://www.google.com/');
curl_setopt($handle, CURLOPT_VERBOSE, true);
curl_setopt($handle, CURLOPT_RETURNTRANSFER, true);
curl_setopt($handle, CURLOPT_STDERR,$f = fopen($verbosPath, "w+"));
curl_exec($handle);
fclose($f);
?>
