Script der skriver i txtfil

Hvis du bruger:

PHP5 -> www.php.net/file_get_contents
PHP4 -> www.php.net/fwrite

Der er gode eksempler på begge sider.

fopen()
:O)

http://dk.php.net/manual/da/function.fopen.php

Edit: PHP5 -> www.php.net/file_PUT_contents

Fatter ikke en hat af de der php sider :)

Jeg forstår det følgende:

<?php
$filename = 'test.txt';
$somecontent = "Add this to the file\n";

// Let's make sure the file exists and is writable first.
if (is_writable($filename)) {

  // In our example we're opening $filename in append mode.
  // The file pointer is at the bottom of the file hence
  // that's where $somecontent will go when we fwrite() it.
  if (!$handle = fopen($filename, 'a')) {
        echo "Cannot open file ($filename)";
        exit;
  }

  // Write $somecontent to our opened file.
  if (fwrite($handle, $somecontent) === FALSE) {
      echo "Cannot write to file ($filename)";
      exit;
  }
 
  echo "Success, wrote ($somecontent) to file ($filename)";
 
  fclose($handle);

} else {
  echo "The file $filename is not writable";
}
?> ¨

Men hvordan skriver man så til det vha en formular?

Jeg har fået den til at skrive i en formular med følgende:

<form action="<? echo $_SERVER['PHP_SELF']; ?>" method="post">
Tekst: <textarea name="tekst"></textarea>
<input type="submit" value="send">
</form>
<?php
$filename = 'test.txt';
$somecontent = $_POST["tekst"];
if(strtoupper($_SERVER["REQUEST_METHOD"])!="POST")
  exit();

// Let's make sure the file exists and is writable first.
if (is_writable($filename)) {

// In our example we're opening $filename in append mode.
// The file pointer is at the bottom of the file hence
// that's where $somecontent will go when we fwrite() it.
if (!$handle = fopen($filename, 'a')) {
echo "Cannot open file ($filename)";
exit;
}

// Write $somecontent to our opened file.
if (fwrite($handle, $somecontent) === FALSE) {
echo "Cannot write to file ($filename)";
exit;
}

echo "Success, wrote ($somecontent) to file ($filename)";

fclose($handle);

} else {
echo "The file $filename is not writable";
}
?>

Men kan man ikke få den til at slette det gamle indhold i test.txt inden den tilføjer det nye??

test.txt skal altid kun indeholde den tekst der er skrevet som det seneste.

har selv fundet en metode...
