Re: [PHP] another GD question
Conor,
This works for me I even tried 6000 pixels and did not fill it. The
stripping of tags doesnt work so well but im sure youve already got
that covered so just replace it with your code.
]|\n)*>", "", $buffer));
}
fclose ($fh);
header ("Content-type: image/png");
$im = ImageCreate (640, 3000);
$background = ImageColorAllocate ($im, 255, 255, 255);
$foreground = ImageColorAllocate ($im, 0, 0, 0);
$index = count ($out);
for ($i=0; $i <= $index; $i++)
{
$l += 10;
ImageString ($im, 1, 5, $l, $out[$i], $foreground);
}
ImagePng ($im);
?>
Hope this helps,
Stewart

Re: [PHP] Valid characters for filenames. List available?
Im not the best at writing regex, but this could be represented as
$filename = ereg_replace ("[^a-zA-Z0-9.-_]", "_", $filename);
Someone correct me if I am wrong (this is what im using to rename
uploaded files, seems to work).

Re: [PHP] is_uploaded_file() emulation?
$owner = fileowner ($file);
returns a string containing the owner or false. see
