While it's true that that will get you a version string, if you're
going to actually check it, you need:

http://www.php.net/manual/en/function.version-compare.php

to do so reliably. Version strings are messy things.

in short: yes.

you can unset() in this way till the cows come home and
not suffer undue consequences.

if while/list/each & foreach were women, while/list/each would be selling
fish on a market stall & foreach would be having her feet massaged while drinking
dry martini at 35,000 feet :-)

but I guess it's not the done thing to call a language construct sexy ;-)

The foreach statement works because you are getting the array index
($k) to unset the array item. I think somewhere in the manual it says
it's unsafe because some people might think you could just use unset
($v) to unset the array item. Which wouldn't work because $v is more
of a temporary variable and not a reference to the array item.

I would *think* (just my opinion without much thought on a Friday
morning) that this would/could be unsafe _if_ it was a for loop on a
numerical indexed array. Of course, my thinking may change after my
first bottle of Dew. ;)

For the longest time, I hated foreach. Looked at other people's code
who used it, and just wanted to strangle them. However, I was sorta
forced into it about 8 months ago, and now I'm in the camp of, "Damn, I
really like this".

this function might change your mind (I take it you have had your Dew by now :-):

     function resolveArgs($args)
     {
         $args = array_values($args);

         for ($i = 0; $i < count($args); ++$i) {
             while (isset($args[$i]) && is_array($args[$i])) {
                 array_splice($args,$i,1,array_values($args[$i]));
             }
         }

         return $args;
     }

basically it flattens a multidimensional array - i use it for handling DB query
arguments (makes it easier to pass around args whilst build highly dynamic queries)

so intrinsically its not unsafe to manipulate the array - only you have the potential
to shoot yourserlf in the foot :-) then again both Richard and John have more than enough
skills to do that anyway ;-)

new-fangled is putting the boat out a bit thought :-) it's been around since 4.0,
I guess your looking forward to being able to use foreach to iterate over php5 object ;-)

If you do this this, you must make sure you have some sort of session

This works fine for me on one site I maintain, though not with
readfile(). When testing readfile() always crapped out at around 2Mb,
whereas fopen() and a while loop with fread() working perfectly, even
for larger files (up to 200Mb). Not tested this on high traffic, though
it all depends on how large you files are.

right and maybe its easier to just index thing like '5.11' as
'511' - ie just stripping off everything not alphanumeric ...
amnd doing the same with whatever people search on. I have used
a similar technique to make it easier to search for text/words that
contains letters with diacrites (e.g. 'e acute' becomes a plain 'e')

and never underestimate a users ability to start writing about eating
dessert in the desert, no doubt they had sandcakes. ;-)

You could use the pspell extension; add your manufacturers to your
personal word-list and use pspell_check() to check the spelling and
pspell_suggest() to suggest alternatives.

How do I "index thing like '5.11' as '511'"? (I know how to strip off
the characters. It's the indexing part that I'm not sure about.)

Better yet! Icecream flavored snakes!

Thanks,

you have another problem - in that all these very specific strings
that you are posting could very well be being mangled in someway
because of the mail transport. in fact I doubt it comes thru in
way that makes it testable at all.

it doesn't help that googling for 'dcomzlib' brings up your own posts
as the first results. not very helpful.

interesting problem - sorry I can't help

Is this thread any help?

http://lists.apple.com/archives/QuickTime-java/2003/Sep/msg00038.html

Looking at your binary data in a hex editor, you've got what looks
like a cmvd header at the start. If the next four bytes are the
length of the compressed data, then you've got probably got 990 bytes
following that that you should be decompressing.

Hello,

I have a problem with the persistence of environment variables when
mixing PHP and SSI (Apache) and I am not sure if I just made an error
or if this approach cannot work at all.
So please consider the following files:

setvar.shtml
-------------------------------------------------
<!--#set var="myvar" value="myval" -->
-------------------------------------------------

showvar.php
-------------------------------------------------
<?php echo apache_getenv( "myvar" ); ?>
-------------------------------------------------

info.shtml
-------------------------------------------------
<!--#include virtual="setvar.shtml" -->
<!--#include virtual="showvar.php" -->
-------------------------------------------------

info.php
-------------------------------------------------
<?php
  virtual( "setvar.shtml" );
  echo apache_getenv( "myvar" );
?>
-------------------------------------------------

What I would expect is that you get the same result if you call
info.shtml and info.php. What happens when I tried (PHP 4.3.10 with
both Apache 1.3.33 and 2.0.53): the shtml shows the variable but the
php does not, it seems to "forget" the variable set in setvar.shtml.
Please, can anybody tell me what is going wrong here?

Regards, Christoph

have yuou tried include/require here instead of virtual()

I imagine that the env of the subprocess wouldn't affect
the env of the parent process - i.e. to me it makes sense
if you say the env var in the subprocess is not available in
the parent process.

Nope, both include and require result that the content of setvar.shtml
shows up literally in the output without the SSI having been processed
by Apache.

ok, and if you stick the following in 1 file and call it?:

<!--#set var="myvar" value="myval" -->
<?php echo apache_getenv( "myvar" ); ?>

... just thinking out loud here.

Ok, I tried this by configuring Apache such that .php-files are also
parsed for Server Side Includes and wrote it the way you suggest. Now
I am really confused: the SSI statements are obviously recognized
because they do not appear in the resulting file but
a) apache_getenv does still not return the value for the variable but
b) if I call phpinfo() instead of apache_getenv the variable "myvar"
plus the set value is shown correctly in the "Apache Environment" and
c) an SSI "<!--#echo var="myvar" --> after the php block also gives the
correct value

Perhaps I return to what I primarily intended to ask: is it really the
wanted behaviour of virtual() that changes that are made by the
included file do not influence the environment of the including file?

Regards, Christoph

I just looked at apache_getenv():

string apache_getenv ( string variable [, bool walk_to_top] )

the second arg maybe something to consider?
also does getenv() [http://php.net/getenv] have the same problems?

I would say yes because virtual() create a sub-process, with it _own_ env.

Hello,
     I've been reading up on printing out documents using PHP (using Printer
functions calls in the php manual)

I'm using a Linux and/or FreeBSD operating system to run my php code on (in
apache). However, I am surfing these pages using a Windows XP machine.

Has anyone ever tried having a print button (or link) in php that would make
Whatever page is being displayed being printed with the above scenario?

How might you of gone about it to make it work? (the Linux or FreeBSD box is
not configured to have a printer on it, shared or local, does that make a
difference? )

Would appreciate any feedback. Thanks!

either you let the client (browser) print the page - this has nothing to do with
php OR you let the server print 'something' (based on a specific request from the user
- i.e. he clicked on 'print' link or something) in which case you will _need_
to have access to a printer from the server (i.e. it needs to have a printer configured)

basically if the server 'has' no printer it can't print.

In PHP4 I never used any DOM implementation, I started to use DOM only after
the PHP5 release, so I'm not the best to answer your question. :)
Anyway I think that there is some implementation in the PEAR repository. Try
to search there.

Best regards.

Hi,

I have some checkboxes on my page which correspond with boolean fields in my
database - actually they are TINYINT's in which I store a 0 or 1 in for
false and true values respectively.

Is it possible to loop through all $_POST values to see if it is a checkbox?
If so then for that element if it is equal to 'on' then change it to 1
otherwise change it to 0?

Thanks for your advice.

Yes and no.

1. You can't determine by the POST variable whether it was a checkbox
or a text field unless you test for 1/0 or a string, but even then,
what if someone types a 0 into a textbox that was supposed to be an
address (input validation). The other option is to name the checkbox
something like "question1_chkbox" and do a strstr() to see if the POST
variable name contains "_chkbox". But you should know what the
variable names of your checkboxes are anyways, so I don't know why
you'd test to see if it was a checkbox.

2. Only set checkboxes (checked) are passed through POST and GET. This
is fine if it's a one time form and you just need to know if they said
"yes" to subscribing to your newsletter, but if it's a form they can
go back into to modify settings (i.e. their account) then you need to
test to see if they unchecked a box which will not be passed back to
you via POST. Basically you'd set all the fields to 1 if the checkbox
variable appeared in the POST, and set all the rest of the fields to
zero (because if it wasn't in the POST variables, it was unchecked).

foreach($_POST as $key => $value){
  if
($value=='on'){$_POST[$key]='1';}elseif($value=='off';){$_POST[$key]='0'};

Yes. And, if so, yes.

If you have a checkbox you just test if the value is set with isset()
if it's not set they never selected the checkbox.

Or if thats not what you mean maybe this could help

I usually place a hidden field with the same name as the checkbox
field before the actual checkbox field. I store my 'false' value in
there. If the checkbox is checked the hidden field is overridden.

<?php

error_reporting( E_ALL );

if( isset( $_POST[ 'submit' ] ) )
{
     echo '<pre>';
     print_r( $_POST );
     echo '</pre>';
}

echo <<<EOF
<form method='post' action='$_SERVER[PHP_SELF]'>
<input type='hidden' value='0' name='blah'>
<input type='checkbox' value='1' name='blah'> Blah?
<input type='submit' name='submit'>
</form>
EOF;

?>

Same way you do it outside the class:

Foo::getMe();
