Re: [PHP] Q: Use getImageSize() on image data from email?

In your situation, I'd write the thing out to a temporary file. In that case I'd consider using ImageMagick's identify command rather than getImageSize(), since it handles many more image types.

Re: [PHP] PHP includes without access to the default directory
On Thu, 5 Dec 2002, Gundamn wrote:
I have a hosted account. As such, I am unable to use the default location
for files when used with the include command. So could somebody tell me how
I can either make it go to a different directory, or to link to something
(and how to add the variable as the filename)?
Thank you in advance.
My usual approach is to have an includes/ directory, at the same level
as the htdocs/ directory, and thus outside the webspace. In this
includes/ directory I put an include.php file which includes any other
files needed with include_once, like so:
?
include_once INC_DIR . '/config.php';
include_once INC_DIR . '/functions.php';
?
In htdocs/ I put another include.php, which basically says:
?
define ('INC_DIR', '../includes');
include INC_DIR . '/include.php';
?
In any subdirectories of htdocs/ I put a similar file, except one level
deeper it'd be:
?
define ('INC_DIR', '../../includes');
include INC_DIR . '/include.php';
?
For each subdir level, add a ../ to the define.
On a hosted account, you may instead have to put your includes/
directory elsewhere. In this case, the include.php in htdocs/ would
just be
?
define ('INC_DIR', '/path/to/includes');
include INC_DIR . '/include.php';
?
and the sub-directory scripts just
?
include '../include.php';
?
Either way, the goal though is to have an include.php file in each
directory of your webspace that references a single include.php file
with relative (../) paths. Coupled with keeping your includes outside
the webroot, this can make include files a lot less troublesome.
A bit of overhead, true, but it keeps my configs, db passwords, and
library code entirely out of the webspace. I've used it successfully in
a large site (150 user-accessible scripts, 25 library scripts, totalling
about 1M of php)
One big warning about include files... PHP's include functions work
counter-intuitively in that all relative paths are relative to the
script that caught the user's request. Thus if you have a bunch of
scripts in a lib/ directory, they can't include each other without
taking into account the path from the calling script... Thus why I try
to define INC_DIR as early as possible if it's relative.
Hope this helps...

Re: [PHP] last updated ?
Dumb question here but whats the general practice regarding putting a website last updated: entry on a web page? Does the web master manually enter in today's date in a database table entry and let PHP display. Is it statically added to the HTML page? Etc... If you want website last updated then from a database sounds OK but where I'm working its commonly a page last updated wanted. In this case its just a manually entered date in html in the page. Or use stat() to get the page's mtime, something like ? $stat = stat($HTTP_SERVER_VARS['SCRIPT_FILENAME']); $date = strftime(%c, $stat[9]); print Last update: $date; ?

Re: [PHP] test for ascii or binary string

Is there a way to determine if a string has ascii or binary data in it?
I've used this kind of approach in the past to determine which encoding
to use on a string which may contain text or an image. Basically it
uses addcslashes to escape non-ASCII chars, then strips all
non-backslash chars, and takes the size of the string... $size should
contain the number of bytes (out of 1024) that were escaped, and should
be very low for clean text, and pretty high for binary. This was made
for analyzing blobs, but maybe the approach is useful...
$text = addcslashes(substr($string, 0, 1024), \\\'\0..\37\177..\377);
$size = strlen(preg_replace('/[^]/', '', $text));
if ($size 200)
print mostly text, use addslashes;
else
print mostly binary, use base64_encode;

I've checked around a bit, looked at some script sites, but nothing seems to give a clue. I *think* it might be possible to set something like this up, but I'm not sure. Streaming how? I've got a PHP script that plays MP3 files off the disk through an HTTP stream, that might be useful for you to start with. I wrote so I could figure which MP3s were being played regularily, versus ones that could be deleted. You could probably extend it by reading from some FIFO on your server, that another process was writing the MP3 stream into, though you'd lose the ability to seek in it... Mail me direct if you're interested. It includes the shoutcast metadata for updating the stream title as it goes, however it appears winamp ignores this data unless the response from the server is ICY/1.0 200 OK rather than the HTTP 200 OK... As far as I can tell after checking the SAPI source and asking here, it's not possible to override that. -- Morgan Hughes C programmer and highly caffeinated mammal.

There's a bunch of commented-out calls to a dprint() in the script; this

print debugging output to a MPEG stream! A replacement could be cobbled

This one bit me when I started working with GD 2.x as well. Simply draw a filled rectangle over your entire canvas in the color you want: ? $im=imagecreatetruecolor(50,50); $COULEUR_BLANC=imagecolorallocate($im,255,255,255); imagefilledrectangle($im,0,0,49,49,$COULEUR_BLANC); header (Content-type: image/png); ImagePNG($im); imagedestroy($im); ? The reason seems to be that when you create an indexed-color image (imagecreate()) gd sets all pixels to index 0, and when you allocate your first color, that's index 0. Thus all background pixels magically become that color. When you use imagecreatetruecolor(), it sets all the pixels to black, and you have to explicitly draw them in to get them white. -- Morgan Hughes C programmer and highly caffeinated mammal.
