Well, then just use the query to decide how it should look like.
Mysql timestamp is amazingly easy to work with.
whatevertable,date_format(timestamp_table, 'what should it look like') as
timestamp or use another name if you need both like I do.

the simplest answer is actually yto make mySQL give you
the data in unix timestamp format in the first place:
SELECT UNIX_TIMESTAMP(my_field) AS my_timestamp FROM foo WHERE id=1;

trick for you. You use the Perl script in the action attribute of
your form. The Perl script saves the entire posted output to a file,
then it sends back a page which uses Javascript to redirect back to
the
php script, where you can process the file. You send the file name
back
to the php script from the perl script in the query string of the url.
At that point, why not just have Perl call PHP?
Surely Perl can do something not unlike 'exec' or whatever to run any
shell script you want...
I sure wouldn't do another round trip to the browser and add JS into
the middle of this solution, if it's viable...
Wouldn't work for me, as I can't do Perl.
Perl could, could of course do the whole job. But since the Original
Poster was (I assumed) not particularly familiar with Perl, I was
essentially providing a Perl script to do the base essentials. So my
hack would put him right back into PHP. If he execs from Perl to a PHP
script to do the processing, then he would have to augment the Perl
script to send back HTML to the browser, and if he can do that he can
probably stick with the Perl altogether. Anyway, that was my reasoning.

I want to list the date and time a file was created so I want someting like..

Ive been playing around with the LS options but I dont know what flags I need.
Closest I could get was..
ls -g -o -t monkey.txt
-rw-r--r-- 1 393 Apr 21 18:57 monkey.txt
What flags would I need to get rid of -rw-r--r-- 1 393
Thanks
In html, try this:
Last updated <?php echo date("M j, Y",getlastmod());?>
Ad the time as you may.

Hi,
In my web application, end user is able to load images (png, jpeg, gif,..)

i do not want to check the extension because this is easily faked...
just by
renaming it.
Does it exist a technique for that ?
thanks a lot,
Is there anything wrong with just using $_FILES['upload_name']['type']?

$_FILES['upload_name']['type'] appears to believe the extension. Try
it--upload a file with a misleading extension.
This same question was asked yesterday and the advice was to use
string *mime_content_type* ( string filename)
That doesn't seem to get fooled very easily, though I suppose you could
fool it if you went to the effort of, say, setting up a fake image
header, when what you are sending is a time bomb.

M.
Yeah right, a time bomb with an image header :P
It should have an ELF header :) But then it would be detected by the
mime_content_type i guess.

The proper way to handle special control PCRE characters like "\" is to use the hex [e.g., \x5C] value. Then you won't
have a problem. The engine knows you want the the object treated as a character and an a control.
[EMAIL PROTECTED] wrote:
-- or maybe it's just the PCRE extension
-- or quite likely I have got something wrong
Hello members,
I'm hoping you could enlighten me.
Using error_reporting = E_ALL | E_STRICT, I tested the following
statements:
<?php
preg_match('#\\#','any-string'); => warning
preg_match('#\\\#','any-string');
preg_match('#\\\\#','any-string');
preg_match('#\\\\\#','any-string'); => warning
preg_match('#\\\\\\#','any-string'); => warning
preg_match('#\\\\\\\#','any-string');
?>
This seemed strange:
warnings with 2 and 6 backlashes
no warnings with 3, 7
warning with 5 but not with 3 and 7.
The warning related of course to no matching delimeter '#' being found.
So I wrote a little test script (preg.php) to test up to 10 backslashes:
<?php
for($i=1; $i<=10; ++$i) {
echo "\n---------------------------------\n";
echo "Number of '\\' is $i \n";
$bs = '#';
$bs .= str_repeat('\\',$i);
$bs .= '#';
echo 'Pattern is: ' . $bs . "\n";
$php_errormsg = "";
@preg_match($bs, "anystring") . "\n";
if($php_errormsg != '')
echo "error\n";
else echo "ok\n";
}
?>
Here is the output:
$ php preg.php
---------------------------------
Number of '\' is 1
Pattern is: #\#
error
---------------------------------
Number of '\' is 2
Pattern is: #\\#
ok
---------------------------------
Number of '\' is 3
Pattern is: #\\\#
error
---------------------------------
Number of '\' is 4
Pattern is: #\\\\#
ok
---------------------------------
Number of '\' is 5
Pattern is: #\\\\\#
error
---------------------------------
Number of '\' is 6
Pattern is: #\\\\\\#
ok
---------------------------------
Number of '\' is 7
Pattern is: #\\\\\\\#
error
---------------------------------
Number of '\' is 8
Pattern is: #\\\\\\\\#
ok
---------------------------------
Number of '\' is 9
Pattern is: #\\\\\\\\\#
error
---------------------------------
Number of '\' is 10
Pattern is: #\\\\\\\\\\#
ok
End of output.
This agrees with my understanding of backslash escaping (I hope that's
right) but now I can't understand why I got the results earlier (shown
in my first script).
Many thanks.

Hi all how can i make my phpmyadmin run fast on windows ? I installed
phpmyadmin on a linux and windows machines, but the windows version runs
(executes) too slow, i.e. it takes to long for a page to be loaded, while it
take less that 3 secs for the linux version. Both however run on the same
system config.

It's not phpmyadmins fault, I've never had speed problem with/in windows in
such manner. Of course that doesn't do much for suckiness

You say they both have the same config, so do you mean that they both
have the same version of PHP, same computer setup (Memory, CPU speed,
HDD speed), both running the same version of Apache, and that both are
running as either CGI or an apache module?

Hi
I'm would like to avoid PHP usages that are deprecated with
regard to PHP 6. I would also like to code according to
what is regarded as best practice. Are there any web
resources that I can read to keep up to date?
For instance:
1) safe_mode is deprecated. (The PHP manual gives me the answer)
2) Are named accessor/mutator methods recommended over the
__get() and __set() magic methods? (A best practice question).
Thanks
