Is there a module to be activated or what has to be installed to have
ttf support in php?
My port on FreeBSD does not have an option for ttf support under make
config .
I'm trying to learn & understand the following:
In file1 : <img src="button.php?s=36&text=PHP+is+Cool" />
In file2 (button.php)- originally php3 :
<?php
Header("Content-type: image/gif");
if(!isset($s)) $s=11;
$size = imagettfbbox($s,0,"times.ttf",$text);
$dx = abs($size[2]-$size[0]);
$dy = abs($size[5]-$size[3]);
$xpad=9;
$ypad=9;
$im = imagecreate($dx+$xpad,$dy+$ypad);
$blue = ImageColorAllocate($im, 0x2c,0x6D,0xAF);
$black = ImageColorAllocate($im, 0,0,0);
$white = ImageColorAllocate($im, 255,255,255);
ImageRectangle($im,0,0,$dx+$xpad-1,$dy+$ypad-1,$black);
ImageRectangle($im,0,0,$dx+$xpad,$dy+$ypad,$white);
ImageTTFText($im, $s, 0, (int)($xpad/2)+1, $dy+(int)($ypad/2), $black,
"times.ttf", $text);
ImageTTFText($im, $s, 0, (int)($xpad/2), $dy+(int)($ypad/2)-1, $white,
"times.ttf", $text);
ImageGif($im);
ImageDestroy($im);
?>
ONLY the above & nothing else. So far, all I get is a small blue square.
Replacing the $text with the text just gives a rectangle a bit wider.
gd is installed but ttf is not, so I figure that is the culprit.
But how is the text supposed to be assigned to $text from file1?
TIA

on unix systems, ttf support should be there with freetype - which
supports both ttf and postscript type 1 fonts (and probably also
supports .otf though I haven't tried)
enable freetype and use the php freetype functions.

addendum to my earlier reply -
make sure your gd library is built with freetype as well, and make sure
it is freetype 2.
I'm guessing your gd library already is, but ...

Those are attributes of the file for which you dont have access
remotely, and the only way to access this information without an
upload will be using the same hacks as those spywarez use. A
technology like flash has read/write access to the remote user's disk
(to a certain extent), you could use flash to get that information and
make it send it to you, same thing could be done with ActiveX, etc...
PHP, JS and HTTP protocol cannot acheive what you want. (PHP is
server-side, HTTP is for communication only, JS is client-side but
locked down very much).
However, at a very low level, it might be possible to achieve this in
PHP, you could do the upload as if you wanted the whole file. But the
first packet received will contain the HTTP Header, and in the header,
you should have all the info you need (filename and size of data).
So, low-level speaking, as soon as you receive the first packet and
have the info, you just need to close the connection (remote end might
display an error msg saying the upload failed, etc). PHP supports
sockets connections, so you could make a basic 'server' that listens
on another port to perform this. But i see no way to acheive your
goal without complications.
Good luck!

I don't like that syntax at all. You would have to scrutinize code
even more to determine whether a statement like this was intentional
or a botched ternary operator. I'm not sure there is a need for a
function like ifset/ifsetor, but I'd MUCH rather have a clear function
name that could easily be found in the manual than mangling the
ternary operator.

Hi Everyone,
I'm trying to get Chrome to output html information as it comes thru. We
have an iframe running a php script, and when the php script receives
information, it outputs it. FF, IE, and Safari all work just fine, displays
the info as it comes in. However, Chrome is not. It will only display the
information after the php script stops executing.
I am outputting this after every echo:
echo str_pad( "", 4096 ) . "\n";
flush();
ob_flush();
ob_implicit_flush();
Has anyone else had this issue? Anyone know how to fix it?

Have you tried a bigger pad? Try... oh I dunno... 40096. if that works
then you can chop back until you find the threshold. Seems to be though
that it might be better done as AJAX.

Rob.

Hi,
I tried that, didn't work at all even up to 144096 on the pad, but no dice.
Ajax unfortunately isn't an option in this particular case.

Maybe, I'm open to suggestions:
Here's the basic way the application works. main index renders, javascript
runs to create an iframe, and set the src='phpfile.php' that runs in a
continuous loop. it connects to the server, and then listens for output.
Disconnecting from the server isn't an option at all, or else the
application will not function properly. It needs to have the constant
"stream" to the server.
Is there a better solution for this?

I presume your backend script is running something that passes the data
to the browser un-interrupted... maybe a shell script? You can wrap this
in popen() or proc_open() and read the output as you would a file. This
can then be queued for consumption by an AJAX script.
Cheers,
Rob.

Ah ok, I've never used either of those before. I am going to give that a
shot and will let you know how it goes. I should be able to bolt that on
quickly. Thanks!

I am writing CMS, that will be able to edit files.
For editing I put file inside textarea, but when I open file that has
textarea element inside it I lose (read: don't show data in the
textarea element.) the data after the inside </textarea> element.
Any suggestions how can I fix this?
Thanks in advance,

You need to use htmlspecialchars on whatever you place inside the textarea:
<textarea name="content"><?php echo htmlspecialchars($content); ?></textarea>

thanks. i really wanted to confirm that it's absent from the language. i've

so I guess the problem is a couple of quotes, isn't it?
otherwise define object statically and externally and use json_decode ;-)

You made an array-- not an object.

you are in PHP, not in JavaScript.
In PHP arrays are like collections or hash tables.
if you strictly need object cause
$o->stuff
is better than
$o['stuff']
having exactly the same number of characters, you can create a function like
function o(array $a){
$o = new stdClass;
foreach($a as $key => $value)
$o->$key = $value;
return $o;
}
and the syntax will be
$o = o(array(
'a' => "b",
'c' => "d"
));
spot the difference from (object) array(whatever) ?
I do not ... and that's why json_encode resolves associative arrays rather than
list automatically but still, if you are in PHP, you should think about being
familiar with associative arrays, also because so far is the only class you
cannot create/extend.
class string {
// ok
}
class object {
// ok
}
class array {
// no way
}

First off, you compared the syntax between creating a PHP array and a
JavaScript object when the previous post specifically spoke about
getting a PHP "OBJECT". Now you've made a rather lengthy and redundant
post trying to describe to me objects versus arrays in PHP. Lastly
you've suggested writing a function to convert an array to an object
using a foreach loop for the members which is completely unnecessary.
The following will suffice:
<?php
function o( array $a )
{
return (object)$a;
}
?>
... and the syntax will be:
<?php
$o = o(array
(
'a' => "b",
'c' => "d",
));
?>
But why bother when you could have just done:
<?php
$o = (object)array
(
'a' => "b",
'c' => "d",
);
?>
Cheers,
Rob.

With the wide range of users on the list, I'm sure there are plenty of
opinions on what are good graphical IDE's and which ones to avoid. I'd
like to get away from using notepad.exe to code with due to its
limitations. Something that supports syntax/code highlighting and has
browser previews would be nice features. I'm looking at Aptana
(www.aptana.com) but it seems like it is more complicated to use then it
should be. Either Linux or Windows IDE (i run both OSes)

Not an ide - I use bluefish, which is a gui text editor with syntax
highlighting. It's an X11/gtk2+ application, packaged for most Linux
distribution (ie yum install bluefish on Fedora or RHEL)
For previewing, I just run a web server on my development box.
Only hitch with bluefish - the syntax highlighting sometimes gets
confused and it drops the highlighting. Press F5 and it reloads.
I believe there is a windows port of bluefish but if I was on windows,
I'd probably just use Homesite (not free).

Look at phpEdit. It has everything you are looking for and is rock solid. I love the folding and

Eclipse + PDT is my recommendation FWIW...

Try out N++. It's very good, supports a whole bunch of languages by
default, has folding, and you can tweak the syntax highlight if you
want. (You don't need to though.)
Takes two minutes to install, and 45 seconds to uninstall it if you
don't like it. It's worth a try.
