Some may ignore most won't. Modern phones have megabytes of memory. Anyway
this is not the problem. There is a fine working custom http server but it
is for windows and since we're migrateing to Linux we/I have to produce a
solution. So I pick up PHP/Apache and now I have a problem :(

WILD GUESS
It sounds like the phones are simply ignoring any image larger than X
bytes.
Actually, I thought that size limitations would be an issue as well.
Especially for images... and especially for my dinosaur of a phone :)

Wish you would have stated the original problem in the first place then!
All is not lost. If I were you I would start by going to
http://www.hawhaw.de and checking to see if that fit my needs.

If hawhaw doesn't work and you can't bend PHP / Apache to do what you
need (at least not quickly enough) you could always try emulating
windows on the Linux box and running that custom server. It would
totally blow (if it even worked), but hey, it's a last resort.

Starting over since my last thread had too little effort put in it. I
have this script that should create a multi-demensional array that would
resemble a directory structure. The problem is that after adding one
element to a "folder" it appears to be creating a new object instead of
adding another item to the current object. So there can only be one
"file" or "folder" in the parent "folder" with the exception of the top
level. My entire script is below.
Thanks, Jon

Hi,
I am testing the following code that pushes a file to the browser
(Apache 1.3 + PHP 4.3.8 but tested also under several other configs)
Try it with a BIG test1.zip (e.g. 100M in size)
<?php
ignore_user_abort();
set_time_limit(0);
session_save_path('/tmp');
session_start();
$sFileName = 'test1.zip';
$sFileDir = '/var/www/html/';
header("Content-Type: application/octet-stream");
header("Content-Disposition: attachment;filename=\"" . $sFileName . "\"");
header("Content-Length: " . filesize($sFileDir . $sFileName));
header('Pragma: cache');
header('Cache-Control: public, must-revalidate, max-age=0');
header('Connection: close');
header('Expires: ' . date('r', time()+60*60));
header('Last-Modified: ' . date('r', time()));
$oFp = fopen($sFileDir . $sFileName, "rb");
$iReadBufferSize = 512;
while (!feof($oFp)) {
echo fread ($oFp, $iReadBufferSize);
}
fclose ($oFp);
exit;
?>
What i discovered is that if i keep the 2 session initialisation functions
the script will work ONLY if the allocated memory is greater than the size
of the tested file. If i remove the session functions the script works fine
even if the test1.zip file is very big (hundreds of Megs)
Is it something i do wrong? Or is a bug and i should report it?
I mention that I NEED the 2 functions so removing them is not THE solution.
Nor setting in php.ini a huge memory limit :(
Thank you,
Adrian Zaharia

Hi,
I have a fairly simple script written that uses the mail() function on a
client site hosted at Interland. I have used a similar script quite a few
times before with no problem. However although the script generates no
errors, no emails appear at their intended destination. Interland support
has not been that helpful and they did suggest I try the '-f' option in the
header. That did not work either. Has anyone seen this before, I am running
out of ideas. The mail portion of the script is below:
$headers .= "MIME-Version: 1.0\n";
$headers .= "Content-type: text/plain; charset=iso-8859-1\n";
$headers .= "X-Priority: 1\n";
$headers .= "X-MSMail-Priority: High\n";
$headers .= "X-Mailer: php\n";
$headers .= "From: $emailfrom\n";
$mailsent = mail($emailto, $subject, $msg, $headers,"-f" . $emailfrom);
Any help would be MUCH appreciated.
If you haven't solved this yet, try sending it via SMTP instead of using
mail(). This will require that you send it by first logging into a valid
e-mail account and sending it through a socket. PEAR::Mail
<http://pear.php.net/package/Mail> can do all this for you.
Take a look at the documentation here:
<http://pear.php.net/manual/en/package.mail.mail.intro.php>.

Hi,
Are there any places that might have instructions on compiling PECL

but fileinfo is not considered stable yet.
Chris
Trying a PEAR or PECL list might do you more good. That being said...
are you trying to install packages that are listed as unstable when your
configuration tries to install stable releases?

Yup, use this perl regex:
/^(?:(&)(?!&)|[^&]){1,5}$/
Where 5 above is the maximum length of the string. You can change this to
any positive value and the regex will still work. Basically it says "look
for 1 to 5 single characters where each either isn't an ampersand, or IS an
ampersand but isn't immediately followed by an ampersand". The (?!&) is a
zero-width negative look-ahead assertion which is like other assertions such
as "\b" that don't eat up the portions of the string that they match.
Sample code, tested:
$maxLen = 5;
$testStrings = array(
'a',
'&g',
'd&f',
'adfdf',
'adfsdfff',
'&f&f&',
'&&dfds&',
'dsdf&',
'd&&df',
'dff&&'
);
foreach ($testStrings as $string) {
if (preg_match("/^(?:(&)(?!&)|[^&]){1,$maxLen}$/", $string)) {
print "$string matches.\n";
} else {
print "$string does not match.\n";
}
}
Hope this helps you (pass your exam? ;) )

Great explanation. Thanks from one who has not had an exam for over ten
years.

Hello SargeTron,

Take a look at this random e-mail address generator (hasn't everyone
written one of these? <grin>) that I wrote a bit back.
You should be able to see how to do exactly what you want from it.
http://www.devtek.org/software/randmail/index.php
$upperLowerNumber = rand(1,10); controls the so called seed for the
script because I placed constraints on how often uppercase and numbers
could appear.
Cheers,
Leif Gregory
