Check out the readfile manual page. Someone made a user-contributed
comment about that.
As it happens they came up with pretty much the same solution as I did.

Didn't really follow this thread, but it sounds to me like you have
upload_max_filesize = 2M
which also happens to be the default uploaded filesize limit.

Uh, never mind. I guess I should read the thread. You are downloading,
not uploading. I can't think of anything that would put an exact limit
on the download like that.

Hello all,
I hope this hasn�t been answered a zillion times already, I've tried
everything I know and nothing has worked. The following is the PHP statement
and the HTML rendering. The apostrophe is displayed as is and breaks the
browser. May be I am wrong but I was under the impression that escaping
special characters with one of the these, htmlspecialchars, htmlentities,
and addslashes would replace them with encoded (hex?) value so they wont
break the browser. But it hasn�t worked that way. I am using
charset=iso-8859-1. This is my PHP:
=== This is the PHP ===
<li>
<a href="#"
onclick='document.form1.how.value="<?=htmlentities($row['how'])?>";
document.form1.factor.value="<?=addslashes($row['factor'])?>";document.form1
..submit();'><?= addslashes($row['factor'])?>
</a>
</li>
====== This is the rendering =======
====== (note the heart's apostrophe breaks IE and firefox) ===
<li>
<a href="#" onclick='document.form1.how.value="Pulmonary edema is a
condition in which fluid accumulates in the lungs, usually because the
heart's left ventricle does not pump adequately. In cases of severe
pulmonary edema, the symptoms will worsen and include A drop in blood
pressure resulting in a thready pulse.";

in htmlentities() use the second optional argument with a value of
ENT_QUOTES, which will escape also single quotes and is not the default.

Use htmlentities() instead.

Hello, what exactly do you mean when you say break the browser, if its a
PHP error you get then its something to do with PHP, however, your
javascript is not correct and produces errors, im not too good at
javascript but know when I see an error, i could be wrong but dont think
its possible to have code like your example, I modified it a little to
get rid of the error:-
<a href="#" onclick='document.form1.how.value="Pulmonary edema is a
condition in which fluid accumulates in the lungs, usually because the
heart\'s left ventricle does not pump adequately. In cases of severe
pulmonary edema, the symptoms will worsen and include A drop in blood
pressure resulting in a thready pulse.";'>
Like I say though unless your error is PHP related then its most likely
your javascript code but I could be wrong,
Hope that helps.

You might want to move this to the pear-general list. I have spoken to
alan about a special custom tag like this, would be nice. I think it
could possibly be via the plugin modules ?
I was thinking of building such a tag, and render the dynarch calaneder

However it only returns values to a textfield, where it should be to a
pulldown, but can be done without much effort.

Hello,
I use Oracle and PHP everyday. For the interaction, I use a PEAR
package called DB. In the future if I want to convert to another
database, I should be able to change just one or two lines of code
because PEAR does the rest...

The actual documentation that will interest you most...

Per the instructions in the subscription reply, I tried the following:
For help and a description of available commands, send a message to:
<[EMAIL PROTECTED]>
If you need to get in touch with the human owner of this list,
please send a message to:

Neither of these worked. The first got back a reply saying the server
did not know what I wanted and the second got back a reply saying "If
you are trying to post to one of the PHP mailing lists, the correct

All I want to do is find out what commands I can use with this list
processor. Every other list I use supports a HELP query, but this one

I am subscribed just fine, I just want to see if I can change my

Have you tried changing the subscription options through the website? I
think you can do it by just checking the type of list you're interested in

It may be better to not execute the script through apache at all, you
could use PHP's exec(); function and have it run in the background,
display a count down then refresh say five minutes later to get the result.

I prefer using the backtick operator for the reason that I could never

I run Windows XP Home SP2, Apache 1.3.24 and PHP 4.3.1. I have a php script
which uses the exec function to invoke a win32 application which writes its
results to a file which is then used in what is returned to the browser by the
script. It works.
I wanted to install the same script invoking the same win32 application on a
friends machine which runs Windows XP Pro SP2, Apache 2 and PHP 5.0.4. It
doesn't work.
Investigation/debugging indicates that the exec call simply doesn't invoke the
win32 application at all with no error indications from PHP. (echo statements
either side of the call). I have checked things like the path to the
application (I can call the application from the run prompt ok) and am now
completely stumped.
The relevant bit of my php script is:
....
$execstring="winposd.exe \"${physical}-${logical}-${parameter}\"";
$output=exec($execstring);
....
I am sure this is something very simple! But obviously beyond me.

I prefer using the backtick operator for the reason that I could never
get exec(); to work.
exec() can be disabled in the php.ini (as with any php function), and is
commonly done on shared hosting systems.

Yes it is set to on in php.ini file. I can make it grab files from
other web sites just not with this one. What else can I look at to try
and make it work

Technical Background: How did you do it?
Based on [WY05], we implemented an attack to find random collisions
for the MD5 compression function. It took just a few hours on a
customary PC.

That is incredibly interesting stuff, many thanks for that link! So the
position seems to be that it may not be feasible to reverse MD5, but it
is now feasible to create forged documents / binaries / whatever that
result in exactly the same MD5 hash as the original.
I actually tried it out for myself... and indeed the two different
documents produced the exact same MD5 sum.
Now I'm wondering... does this mean that I now need to download PHP
binaries from multiple "trusted" sources, do the checksums on each
separate download, *and* do a diff for each binary? That way a cracker
has to infiltrate multiple servers in order for me to be affected by a
cracked PHP binary?
Very interesting indeed...

Hi,
I having a problem at the moment, I open a file, try to write in it,
and then remove the file if the write goes wrong (if write count != of
my initial buffer length). But I still get some empty file (and then a
blank page). Could possibly fopen (with a 'wb' flag, and under freebsd
4.11) failed but still create that empty file ?
Where could I get more info on the behavior of fopen/fwrite ?
Thanks for your help.

I am trying to pass a function as an argument to another function, and
then run the first function from within the second function.
Example:
function function0($arg0, $arg1, $arg2) {
function2();
}
function function1($arg3, $arg4, $arg5) {
function3();
do_function($arg5);
function4();
}
function1(5, 100, function0($arg0, $arg1, $arg2));
In the above example, I am running function1(), which includes
function0 as an argument.
I am trying to pass "function0($arg0, $arg1, $arg2)" as an argument to
function1, which will then execute the passed function, including its
passed arguments.
I have had mild success by splitting "function0($arg0, $arg1, $arg2)"
into 2 parts of "function0" and "$arg0, $arg1, $arg2", and then
passing both parts as an argument, such as $arg5 & $arg6, and then
doing this:
function function1($arg3, $arg4, $arg5) {
$args_array = explode(", ",$arg6);
$arg5($args_array[0],$args_array[1],$args_array[2]);
}
However, this causes all of my arguments in the array to be evaluated
as strings and not resources, which they may be.
Also, I don't really like this method, and would prefer a much
"cleaner" way of doing things.
