O.P. overlaying text on image in php
why is it that when i try to overlay a text file with line breaks, it shows some random symbol instead?
![[Image: write.php]](http://ssd.sc47.info/Random/random%20sig/write.php)
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);
?>
(it shows the symbol when the txt just has line breaks or when i replace something with \n)
-this is ansi, utf doesnt work either

RE: overlaying text on image in php
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  |

RE: overlaying text on image in php
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.

RE: overlaying text on image in php
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);
?>
EDIT: Added used code and example
EDIT2: MyBB tags are hard, when you are tired

O.P. RE: overlaying text on image in php
awesome!
but what is the 3rd var in imagettftext()?
code:
imagettftext($im, 12, 0, 150, 60, $color, $font, $text2);
nvm, clicked link
why is it that when I open the file as r+ it acts as though its w/w+ ? (replaces what is already in the file with the string)
http://ssd.sc47.info/Random/random%20sig/post.php
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>
a+ works fine, but i want it to add new line at the beginning of file

RE: overlaying text on image in php
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". |
