why is it that when i try to overlay a text file with line breaks, it shows some random symbol instead?



should be

Some
Random
Text

code:

---

<?php
header("Content-type: image/png");
$im    = imagecreatefrompng("sigs/chichan.png");
$color = imagecolorallocate($im, 0, 0, 0);
$file = fopen("text.txt","r");
$text = fread($file, filesize("text.txt"));
$text2 = str_replace("<br />", "\n", $text);
imagestring($im, 2, 100, 20, $text2, $color);
imagepng($im);
imagedestroy($im);
fclose ($file);
?>

Are you using a windows server? It might have a problem that you are using linux line-endings (\n) and not windows line endings (\r\n)

If your server is *nix then I don't know

i'm pretty sure its debian

I don't think you can do line breaks with imagestring() at all. You need to call the function once for each line of text, increasing the y coordinate each time.

aww. lame.

I'll try to do it my self. if i cant, i'll come for help ;>

ImageTTFText works with line-endings.

code:

---

<?php
  header("Content-type: image/png");
  $im    = imagecreatefrompng("write.png");
  $color = imagecolorallocate($im, 0, 0, 0);
  $file = fopen("text.txt","r");
  $text = fread($file, filesize("text.txt"));
  $text2 = str_replace("<br/>", "\n", $text);
  $font = "arial.ttf";
  //imagestring($im, 2, 150, 60, $text2, $color);
  imagettftext($im, 12, 0, 150, 60, $color, $font, $text2);
  imagepng($im);
  imagedestroy($im);
  fclose ($file);
?>

awesome!

but what is the 3rd var in imagettftext()?

code:

---

imagettftext($im, 12, 0, 150, 60, $color, $font, $text2);

---

code:

---

<?php

$item = $_POST["item"];
$name = $_POST["name"];

if ($item && $name)
    $file = fopen("text.txt", "r+");
    fwrite($file, date("H:m")." - ".$name." - ".$item."<br />");
    fclose($file);
   


?>

<img src="write.php" alt="" />

<form action="post.php" method="post">
    <table cellspacing="0" cellpadding="1" border="0">
        <tr>
            <td>Name/td><td><input type="text" name="name" maxlength="12" /></td>
        </tr>
        <tr>
            <td>Message/td><td><input type="text" name="item" maxlength="30" /></td>
        </tr>
    </table>
    <input type="Submit" value="Shout!" />
</form>

code:

---

<?php

$item = $_POST["item"];
$name = $_POST["name"];

if ($item && $name)
    $file = fopen("text.txt", "r+");
    fwrite($file, date("H:m")." - ".$name." - ".$item."<br />".file_get_contents("text.txt"));
    fclose($file);
   


?>

<img src="write.php" alt="" />

<form action="post.php" method="post">
    <table cellspacing="0" cellpadding="1" border="0">
        <tr>
            <td>Name/td><td><input type="text" name="name" maxlength="12" /></td>
        </tr>
        <tr>
            <td>Message/td><td><input type="text" name="item" maxlength="30" /></td>
        </tr>
    </table>
    <input type="Submit" value="Shout!" />
</form>

but why doesnt it work the way its supposed to =/

There is no "prepend" mode... r+ lets you read and write any position within the file, and the file won't be automatically truncated.

If example.txt contains "aaaaaaaaaa" and you do this...

$fp = fopen('example.txt', 'r+');
fwrite($fp, 'bbbbb');
fclose($fp);

It will contain "bbbbbaaaaa".
