PHP - Doesn't Write To File?

Got a little stuck here.

I'm trying to format an existing .txt file, format it and then write it to .sql file.

Here's my code:

Code: [Select]
$handle = @fopen("nations.txt", "r");
if ($handle) {
    while (($buffer = fgets($handle, 1024)) !== false) {

                      $column = explode("|",$buffer); // format file
                        $myFile = "nation_dump_".date("Y-m-d").".sql"; // create file
$fh = fopen($myFile, 'w') or die("can't open file");

foreach($column as $col)
{
fwrite($fh, $col[0]); //write the first broken segment from explode() to file
}
fclose($fh);
    }
    if (!feof($handle)) {
        echo "Error: unexpected fgets() fail\n";
    }
    fclose($handle);
}

The error is on this line, within the foreach loop.
fwrite($fh, $col[0]);

When I removed the index it only wrote the last line to the file, but I want it to loop through all the lines..

What am I doing wrong here?

I produce a series of php variables in a php strict (mostly come from mysql), and I want to save them as a php file. To be use for "include". What is the safest way to write them in a php file?

I tried to save them in the manner of saving a text file with fwrite as

Code: [Select]
$data='<?php $cat=array('array created in the text'); $string='some value';?>';
$fh = fopen("file.php", 'w');
fwrite($fh, $data);
Now, file.php is a normal php file and I can call it with "include"; but the problem is that this method is not safe. For example, if the string is "There's something", php gives error for the presence of ' in the string. I can skip ' and " by backslash; but this method is costy, as I need to perform this process for all strings to be saved. Moreover, there might be other source of errors too (that I have not encountered yet).

Is there a safe way for writing a php code to file?

Hello Everyone,

I'm new to PHP and got a good big stuff.

I would like to write an image in excel file. There will be almost 600+ rows and each row will have url and qrcode image. I would like to write an excel file which will write url and respective image into the next cell of the url.

Is it possible to write an image in excel file? If yes, can anyone please guide me how? I have read so many post saying to use a pear package but again pear package is not allowing to write jpe/gif it only allows .bmp files. So, pear package is I don't think will work for me. I have also attached an example excel file which is showing the way I require to have an output.

Please anyone if having any idea guide me and let me know.

Thank you in advance for your help.

Looking forward to hear from you soon!

Hey there,

Thanks for taking the time to read my thread, well basically I'm in a bit of a dilemma. I've got a string in PHP containing the contents of a file I would like to be created and I have a method of sending the command to the remote server like so:


$Connection->exec('ps aux'); 


Now my issue is I am unaware of any file editors via command like that don't have some sort of user prompt I've scoured Google for hours searching for the best possible method for this but all the file editors aren't simply processed by one line commands and edited in that same command e.g

Create File -> Write File -> Close File

Is there no possible means of doing that via one line command?.

Here is my string I wish to be written to the file.



$RestartFile = "#!/bin/bash
export SERVER_PATH=/home/client".$Server['server_owner']."/".$Server['server_id']."
cd $SERVER_PATH
while [ true ]; do
./server".$Server['server_id']." &
done");


Thank you for your time.

Hi,

I want to read image file and write in to word document file using php. Actually i am developing shopping cart site. for that i have created barcode image. i need to take print outs. for example if i click print means same barcode should be generate 64 times in word document. how i do it?

i have tried with COM. please check the following code


<?php
// starting word

$word = new COM("word.application") or die("Unable to instantiate Word");
echo "Loaded Word, version {$word->Version}\n";

//bring it to front
$word->Visible = 1;

//open an empty document
$word->Documents->Add();

//do some weird stuff


for($i=1;$i<=64;$i++)
{
   
$word->Selection->InlineShapes->AddPicture("D:\Program Files\wamp\www\b.jpg ",false, True);

}


$word->Documents[1]->SaveAs("D:\Program Files\wamp\www\Uselesstest.doc");

//closing word
$word->Quit();

//free the object
$word = null;
?>


It works fine in local. but it is not working in server  (it says COM.class is missing). i have checked some forums they said it works with MS based operation system.  i have checked with windows only.

Is this the correct way to write binary data to a file?

$string = 'this is a string';
$handle = fopen('b.dat', 'wb');
for($i=0;$i<strlen($string);$i++){
    $hx = bin2hex($string{$i});
    fwrite($handle, pack("H*", $hx));
} 

If so, how do I read it an convert it back to a string?
If it is not correct, how do I do it?

Just trying to create a simple form that will let you enter a message that will get written to a text file.

Code for SetMessage.php:

Code: [Select]

<?php

if($_SERVER['REQUEST_METHOD'] != 'POST')
{
?>

<form method="POST" action="setmessage.php" name="setmessage">
<p>Message to Display:<Input type="text" name="message" size="50"></p>
<p><input type="submit" value="Submit" name="submit"></p>
</form>
<?php
}
else
{
   //Writes the contents of the message to a file
   echo file_put_contents('message.txt', $_POST['message']);
}
?>


When submitting, I get the error "Call to undefined function: file_put_contents() on line 16"

Hi All,

I am presently using a Debian VPS to which, if I need, I can add another disk. In my website, users can upload images, that are then stored in the primary disk into a child directory of a directory called httpdocs. Instead of the primary disk, would it be possible to have them stored in a secondary disk ? I am asking this because I am not sure that a user connected to my website is allowed to run a PHP script intended to write a file in a directory that actually does not belong to the httpdocs directory.

Thanks

I very new to php and all I am simply trying to do is read the contents of a text file and echo it out on the screen.
I have tried many things to see what I am doing wrong but it just simply isnt working for me. I know the server I am using has php enabled as well because I have tried a simple echo and it works fine.

This is the code I am currently using.

<?php
   $file = fopen(file.txt", 'r');
   $read = fread($file, '6')
   echo $read;
?>

also, I have tried this.

<?php
   $file = file_get_contents('file.txt');
   echo $file;
?>

I have a file.txt on the server I am using in the same directory as index.php, I feel like this should be working but I get no result!
Alls I have in the text file is a statement that says "hello world".

I append a string to a file by fwrite as

Code: [Select]
$str= 'dynamic text from each run';
$myFile = "testFile.txt";
$fh = fopen($myFile, 'a') or die("can't open file");
$stringData = "$str\n";
fwrite($fh, $stringData);
fclose($fh);
but I want to avoid duplicate to keep the file small. I want to avoid writing if the term is already saved in the file. I want to have a file containing unique lines.

Is there a way to write a file to a directory on my network?

I tried creating a shortcut called automated and pointed it to the network path.  I also set up a virtual directory called automated in IIS and still could not make it work. I gave it read and write permissions.

error
Warning: fopen(C:\Inetpub\wwwroot\dompdf\automated\resource.pdf) [function.fopen]: failed to open stream: No such file or directory in C:\Inetpub\wwwroot\date.php on line 69

Warning: fwrite() expects parameter 1 to be resource, boolean given in C:\Inetpub\wwwroot\date.php on line 70

Warning: fclose() expects parameter 1 to be resource, boolean given in C:\Inetpub\wwwroot\date.php on line 71

code
Code: [Select]
require_once("dompdf/dompdf_config.inc.php");

$html =
  '<html><body>'.
  '<p>Put your html here, or generate it with your favourite '.
  'templating system.</p>'.
  '</body></html>';

$dompdf = new DOMPDF();
$dompdf->load_html($html);
$dompdf->render();
$pdfoutput = $dompdf->output();
$filename = "C:\\Inetpub\\wwwroot\\dompdf\\automated\\resource.pdf";
$fp = fopen($filename, "a");
fwrite($fp, $pdfoutput);
fclose($fp);

I'm trying to include a routine to catch an error but it doesn't seem to write to a text file within a function. just using the following simple code, even if I simply try to write a letter it doesn't work

 

if ($http_status == 200) {
        return $response;

    } else {


$myfile = fopen("ErrorData.txt", "a+") or die("Unable to open file!");

$txt =  date("H:i:sa d-m-Y")." / Error data- / ".json_encode($response)."\r\n";
fwrite($myfile, $txt);
fclose($myfile);


}

Added code

Ok, so I have an INI file...

OLD HTML=
NEW HTML=


I need to write the contents $oldhtml to "OLD HTML=" and the contents of $newhtml to "NEW HTML="

To store the contents of an ini file to a variable, I just used
Code: [Select]
$config = parse_ini_file("config.ini",1);
$email = $config['Email'];
$host = $config['Host'];
Cant I just write to the file by selecting ['Old HTML'] and ['NEW HTML'], in a fashion similar to the above code?

Hi all,

I'm using a gateway for CC, when they payment is made and then users are redirected back to my site, I grab the order number and echo it as $info so I can display on the user's receipt.

Code: [Select]
<?php
$info=$_POST['OrderNo']; 
echo "$info";
?>

Is it possible to use PHP to either to automatically (onload) submit a form or somehow write $info to a text file so I can reconcile the books later?  I can do the former successfully with JavaScript... but I'd rather make it server-side.

Thanks.
