Hi I need to receive a post data which will be in an xml that is encoded in a base64 format.
I'll be receiving this from a payment gateway. Now all i get is this. My code creates a txt file but is empty. Is there anything wrong with the code? The output should be an xml envelope in a text file.
$body = '';
$fh = #fopen('php://input', 'r');
if ($fh)
{
while (!feof($fh))
{
$s = fread($fh, 1024);
echo $s;
if (is_string($s))
{
$body .= $s;
}
}
fclose($fh);
}
$body = base64_decode($body);
$ourFileName = "testFile.txt";
$ourFileHandle = fopen($ourFileName, 'w') or die("can't open file");
fclose($ourFileHandle);
$myFile = "testFile.txt";
$fh = fopen($myFile, 'w') or die("can't open file");
$stringData = $body;
fwrite($fh, $stringData);
fclose($fh);
I tried to contact the payment gateway and they are telling me that they are getting this error "The remote server returned an error: (417) Expectation failed." where could the problem exist us or them?
Since your file is returning blank, I would recommend verifying the specifications from the payment gateway for your fopen() function. In addition, if you are properly getting data back from them, then I would check the base64_decode() function. I have seen situations where there may be a header or other data at the top of the actual payload data that fouls up the base64_decode and ruins your day.
It looks like you are mixing up your file handlers, can you see if the following codes run:
$body = $HTTP_RAW_POST_DATA;
$ourFileName = "testFile.txt";
$ourFileHandle = fopen($ourFileName, 'w') or die("can't open file");
$stringData = $body;
fwrite($ourFileHandle, $stringData);
fclose($ourFileHandle);
I have just tested the above code myself successfully.
What I suggest you do is trying the following:
Try to put a static piece of data into $body (eg: "$body = 'test';")- and see if that saves - if not then it is an issue at your end.
Delete the file (to remove any permission issues).
Double check the url that the payment gateway is sending to is correct.

I have a little issue while trying to kill time. I am writint to a text file the contents of the filled in form so it is easy to read. At the moment everything gets put int a single line, and therfore I can not tell where msgs begin or end. I wrote a php like this:
$from = $_POST[from];
$friend = $_POST[friend];
$carrier = $_POST[carrier];
$message = stripslashes($_POST[message]);
if ((empty($from)) || (empty($friend)) || (empty($message))) {
header ("Location: sms_error.php");
}
else if ($carrier == "orange_mobile_network") {
$formatted_number = $friend."#orange_mobile_network.co.uk";
mail("$formatted_number", "SMS", "$message");
header ("Location: sms_success.php");
}
Then the SMS/Text message will be sent. After this I wanted to write/store/append the message on a txt file. So I wrote:
$myFile = "sms_Numbers_Mgs.txt";
$fh = fopen($myFile, 'a+') or die("can't open file");
$stringData = $_POST[from];
fwrite($fh, $stringData);
$stringData = $_POST[friend];
fwrite($fh, $stringData);
$stringData = $_POST[message];
fwrite($fh, $stringData);
fclose($fh);
But like I said. Everything works. I just want to be able to read the file and put everything in a new line and possibly format it nicely for easy reading. I do not want to use a DB for storing the TXT as my host is going to charge me.
change this:
fwrite($fh, $stringData);
with this:
fwrite($fh, $stringData . PHP_EOL);
or:
fwrite($fh, $stringData . "\r\n");
You can append PHP_EOL when you write for a platform aware newline. I.e. $stringData = <string> . PHP_EOL;
If don't need it to be platform aware, going with the windows newline is a safe option.
define('CRLF', "\r\n");
$stringData = <string> . CRLF;
fwrite($fh, $stringData);
I do not know exactly Cause you're using. txt instead of a bank, but my tip for this specific case is to work with json format.
Example:
$myFile = "sms_Numbers_Mgs.txt";
$fh = fopen($myFile, 'a+') or die("can't open file");
//assembles a string of type json
$data = json_encode(array(
'from' => $_POST[from],
'friend' => $_POST[friend],
'message' => $_POST[message]
));
//Write in the file
fwrite($fh, $data);
fclose($fh);
//reads the file
$content = file_get_contents($myFile);
$object = json_decode($content);
var_dump($object);
good it is at least better organized.
a hug!
Does the php's echo wait to send data to the screen, until the rest of the script is complete?
So if I have:
<?
echo "Hello World";
$xmlData = file_get_cotents("www.webpage.com");
$myFile = "data_backup.xml";
$fh = fopen($myFile, 'w') or die("can't open file");
$stringData = $xmlData;
fwrite($fh, $stringData);
fclose($fh);
?>
So does the above sample what to show Hello World until the contents from the url are retrived and saved locally?
Yep. unless you flush the data with flush();
All of the scripting in PHP occurs before the page loads, so the answer to your question is: yes, it would wait until the file is retrieved and saved before showing "Hello World".
I may be over thinking this but are there any extra steps I am missing after reading my XML data into a string and before writing it to a local file?
header('Content-type: text/xml');
//MY URL TO A XML PAGE STYLED WITH XML STYLE SHEET
$url = "http://www.mywebsite.com/somexmlfile.xml";
//SAVE CONTENTS OF PAGE IN XML_DATA
$xml_data = file_get_contents($url);
//REMOVE STYLE SHEET INFO
$search2 = '<?xml-stylesheet href="latest_ob.xsl" type="text/xsl"?>';
$xml_data = str_replace( $search2, "", $xml_data);
//WRITE MY DATA TO A BACKUP FILE AND THEN ECHO TO THE SCREEN FOR A FLASH APP CALLING THE INFO
$myFile = "data_backup.xml";
$fh = fopen($myFile, 'w') or die("can't open file");
$stringData = $xml_data;
fwrite($fh, $stringData);
fclose($fh);
echo $xml_data;
The reason I ask this is when I try opening my backup XML file in Dreamweaver it crashes everytime. I was thinking there could be an encoding issue possible.
I have a PHP generated page containing the results of a submitted form, what I would like to do is save this as a .doc file on the server.
After some googling I came across this code which I adapted:-
$myFile = "./dump/".$companyName."/testFile.doc";
$fh = fopen($myFile, 'w') or die("can't open file");
$stringData = "Bobby Bopper\n";
fwrite($fh, $stringData);
$stringData = "Tracy Tanner\n";
fwrite($fh, $stringData);
fclose($fh);
But the problem with this is that I would have to recreate the results in order to manually write them to the file and it doesn't seem very efficient.
So I continued to google and found the PHP manual which left me scratching my head frankly, however I eventually found this:-
ob_start();
// code to generate page.
$out = ob_get_contents();
ob_end_clean();
// or write it to a file.
file_put_contents("./dump/".$companyName."/testFile.doc",$out);
Which will create the file, but doesn't write anything to it. However this seems to be the way to do what (Based on the PHP manual) I want even if I can't get it to work!
Any advice? I don't mind googling if I can figure out a decent search term :)
This sould do it for you:
$cache = 'path/to/your/file';
ob_start();
// your content goes here...
echo "hello !"; // would put hello into your file
$page = ob_get_contents();
ob_end_clean();
$fd = fopen("$cache", "w");
if ($fd) {
fwrite($fd,$page);
fclose($fd);
}
It's also a great way to cache dynamic pages. Hope it helps.
I want to fetch json script and write it to a txt file undecoded, exactly how it was originally. I do have a script that I use that I am modifying but unsure what to commands to use. This script decodes, which is what I want to advoid.
//Get Age
list($bstat,$bage,$bdata) = explode("\t",check_file('./advise/roadsnow.txt',60*2+15));
//Test Age
if ( $bage > $CacheMaxAge ) {
//echo "The if statement evaluated to true so get new file and reset $bage";
$bage="0";
$file = file_get_contents('http://somesite.jsontxt');
$out = (json_decode($file));
$report = wordwrap($out->mainText, 100, "\n");
//$valid = $out->validTo;
//write the data to a text file called roadsnow.txt
$myFile = "./advise/roadsnow.txt";
$fh = fopen($myFile, 'w') or die("can't open file");
$stringData = $report;
fwrite($fh, $stringData);
}
else {
//echo the test evaluated to false; file is not stale so read local cache
//print "we are at the read local cache";
$stringData = file_get_contents("./advise/roadsnow.txt");
}
// if/else is done carry on with processing
//Format file
$data = $stringData
Try this:
// Get JSON Data
$json_data = file_get_contents('http://somesite.jsontxt');
// Write JSON to File
file_put_contents('json_data.txt', $json_data);
