Re: [PHP] Graphics question

[Todd Pasley]

 Jeez, this is simple.  The browser is caching the image.  There's no real
 way to fix that.  There are some headers that may encourage the browser to
 not cache, but there is no sure way to control whether the users will have
 this setting overridden.


I use

 srand((double)microtime()*100);
 $anticache= md5(rand(0,999));

and then


echo IMG
src=\drawpic.php?arg1=blaharg2=blah.anticache=$anticache\ 
\n;

Since this addition, i have never had a problem with cache,

HTH

Re: [PHP] Quick question

[Todd Pasley]

Realistically, there is no difference. It is *slightly* quicker to parse,
but thats about it.

I think it was introduced to satisfy those that have used this type of
syntax in other languages, like C and Perl (which users elsif).

I usually use elseif as its a bit nicer looking (IMHO)

[PHP] imagecreatefromstring

[Todd Pasley]

Hi,


I asked a question similar to this earlier, but I thought it may have
required simplification/rewording. According to the doco,
imagecreatefromstring has the following declaration:

resource imagecreatefromstring ( string image)

Does anyone know how an image can be transformed into a string that will be
in a valid format for use with imagecreatefromstring.

Any help at all would be greatly appreciated.

Cheers,

Todd.

 Hi!

 I've been writing PHP scripts for a long time but never needed to get data

 Can somebody give me a hand? The Oracle database is running on another

 The information I have been given is:

 host (e.g.  somewhere.somewhere.com)
 username (e.g. USER_NAME)
 pw   (e.g. MY_PW)
 databse : PROD
 Function: F_CLAVE_SI_NO(loginnr)

 Basically what I need to do is contact this databsae, execute the function
 F_CLAVE_SI_NO($myloginnr), and get the results.

 The function F_CLAVE_SI_NO is a function from the Oractle database itself;
 it is no one written in PHP.

 Thank you for your help!

Hi

If what you mean is... you want to be able to write to a file on the
browsers computer, then please let us know if you find a way.

To my knowledge, there is not any intended way to do this... you wouldn't
want any old website to be able to manipulate your hard drive would you?

It might be possible if you write an applet, otherwise, pretty much the only
thing you should be able to write to the hard drive is a cookie.

Sure you can, however,

will have to use $GLOBALS to declare $name as a global before you utilise

[PHP] LOC counters

Hi,

Firstly, please resist the opportunity to flame

I'm looking for a PHP (among other things) Line Of Code counter. Has anyone
used any descent ones? I was thinking of writing one myself, but, if there
are others available, I might as well save the time.

There is much debate over the appropriateness of LOC as a measurement, I
have chewed up a lot of time with discussion over this so I'm not going to
bite this time :)

RE: [PHP] Re: unexpected T_SL

[Todd Pasley]

Hiya,

There are two reasons that I can pick up that you may be experiencing this
area:
1) You are not using PHP4 or later
2) you are using windoze and.

Probably the nastiest gotcha is that there may also not be a carriage
return (\r) at the end of the line, only a form feed, AKA newline (\n).
Since Microsoft Windows uses the sequence \r\n as a line terminator, your
heredoc may not work if you write your script in a Windows editor. However,
most programming editors provide a way to save your files with a UNIX line
terminator.
(http://www.php.net/manual/sv/printwn/language.types.string.php#language.typ
es.string.syntax.heredoc)

It doesnt matter whether you use EOD or EOT or any other (naming convention
compliant) identifier.

I hope this helps,

Todd.

Only just noticed this when I read my post...

Why do you want to use verbose?

If you want to capture the output for some reason, use this

exec(cd /change/to/dir; tar cvf /place/for/backup.tar files,
$capturedoutput);

otherwise drop the v (or --verbose) which will chew less resources.

[PHP] .scr Attachments

Hi all, 

As I'm sure you are all aware (but this email is incase you are not), files with the 
extension .scr are executable on all windows platforms.

Just now from someone on the list I have received two emails with .scr attachments. If 
you receive an attachment from this list, please check the extension type very 
carefully before opening it, it is most likely a virus. 

We dont want something like this attacking inboxes clogging up an already very full 
mail list, along with all your freinds/contacts if you do run it.

Once again, I'm sure you guys are aware, but its better to be safe than sorry. There 
is a remote chance that it is not a virus, but i dont trust microsoft and i dont trust 
executable attachments.

Re: [PHP] How can I strip the code from HTML pages to extract thecontents of a HTML page.

[Todd Pasley]

Hi Charles,

Not sure exactly what you are after, but

function displayLinks ($pagecontents) {
$search = '/a (.*?)href=(.*?)(.*?)\/a/im';
$replace = 'a
$1href=recordstep.php?clientid=$clientidtestid=$testidlink=$2$3/a';
return (preg_replace ($search, $replace, $pagecontents));
}

For me, that takes all the links in $pagecontents and modifies the links for
a recorder I am building. You could do something simular with it, although
if you need the name, you might want...

$search '/a (.*?)href=(.*?)(.*?)(.*?)\/a/im';
And $4 would be your name.

I hope this helps.

 I was looking into stripping HTML files that contain alot of links. I
 was trying to avoid the manual way of data entry. The contents i need
 are the name of the link (plain text which sits out side the HTML code)
 and all the a href tags. I would like the a href  (ie.the hyperlink)
 tags to be displayed on the HTML output as plain text. All other HTML
 tags would be kept in place.

 The reason why I am doing this is that I am placing a link's name and
 the http:// link in to flat files, where they can be updated just by
 appending to them. The srcipt that I have does the rest.

 I have looked into the functions suggested but do find the concepts and

Re: [PHP] Simple regexp

Hi,

you would be better off with preg_match, as its a little quicker apparently.

try:
preg_match(/^[:0-9a-f]*$/i,$string)

or change the * to a + to ensure $string is not null

the main problems you had:
- not ensuring that only those characters are found by using ^ and $
- not allowing multiple character by using  * or + or alternative
- having A-Za-Z instead of A-Fa-F

I hope this helps

Note: I used /i to be non case dependant, maybe dropping it and having A-F
as well would be quicker.. not too sure.

Subject: [PHP] Class problem - Fatal error: 


 Hello I get this error:
 
 Fatal error: Cannot redeclare class dmsql in
 /usr/local/apache/htdocs/dm/inc/sql.inc.php on line 4
 
 It happens when a user presses the back button, otherwise when the page
 is first loaded it works fine.
 
 Here's the file called with web browser
 
 include('class_dmsql.inc.php');
 include('class_b.inc.php');
 
 $r = new class_b
 
 Please note that class_b extends class dmsql,
 
 Can anyone help me ?
 
 Thanks
