Hi to all the PHP-Fans out there,

i have a syntax-problem with the folowing preg_replace command:

$returnString = preg_replace("/(href=\")(.+?)(\")/is",
preg_quote("\\1".ebLinkEncode(."\\2".)."\\3"), $returnString);

i'm trying to call my own function within a preg_replace function and it
won't work.
any ideas ? it seems to me, that the quoting is incorrect, but i'm not
shure, why it is incorrect,
especially because i use preg_quote() ...

thanks in advance for some hints !

best regards

Hi Dieter,

You need to use the 'e' modifier as well as 'is' in your pattern. Have a
look in the manual, here:

http://www.php.net/manual/en/pcre.pattern.modifiers.php

"If this modifier is set, preg_replace() does normal substitution of
backreferences in the replacement string, evaluates it as PHP code, and uses
the result for replacing the search string."

Also look here:
http://www.php.net/manual/en/function.preg-replace.php

And check the "Example 2. Using /e modifier" part.

Hope that helps ;)

James

Take a look at preg_replace_callback().

Greetings.

I've written a simple form to allow my clients to upload files to me, and it
works fine EXCEPT that the uploaded file is owned by "www" and I while I can
read the file, I don't have the necessary permissions to delete it when done
...

Since this site is being hosted elsewhere, is there a way I can control
ownership so that I can delete the file? I've written my ISP/web hoster and
received no response -- usually that's their subtle way of telling me I
should ask the PHP quiestion here :-)

Any and all help would be appreciated.

You can stat (get filesize, modification time, permissions) only local 
files - download it first and then get its filesize if you need it.

You can't stat() a remote file - filesize() only works with local filesystems.

However you do not need to know the size of the file to read it - simply do
it in chunks:
        $dataFile = "http://www.healthtvchannel.org/courses/pay/data/test.xml";;
        $fp = fopen($dataFile, "rb");
         $strFile = null;
         while ($chunk = fread($fp, 524288))  // 512 kB chunks modify as needed
              $strFile .= $chunk;
        fclose($fp);

I have an interesting challenge.  I have built an online product catalog

that is driven entirely by the contents of the product database (MySQL).

The entire catalog is implemented in a single PHP script (catalog.php).

The dynamic nature of this implementation allows the catalog script to

generate hundreds of product description pages.



Now, my client has requested that I give him the ability to generate a

static version of the catalog so that he can burn it onto a CD for

distribution at trade shows.  He wants the CD to be a snapshot of the

catalog.  Furthermore, he wants to be able to generate this "snapshot"

frequently so that pricing info on the CD will be current.  To

accommodate this, the process for generating the snapshot must be easy

and intuitive.



My plan of attack is to generate static HTML files by running the

catalog script once for each product in the database. Here is my

quandary; instead of echoing the output to a buffer for Apache to send

off to the client, I need the script to output to a file.  I do not want

to write a second version of catalog.php that writes everything to file.

There must be an easier way to do this.  Is there a way I can access the

output buffer that Apache sends to the client?



Any other ideas?



Thanks,



Ron

Hello!



I'm currently doing some work that requires a mySQL database of actor 
names. For all my actors, I have three columns; first_name, last_name and 
between_name. Because between_name can be written in many ways ("Peter van 
Wibble" or "Fred d'Angelo), and the French have a habit of writing their 
surnames in capitals, I wrote a little function to prepare the actor names 
for output:



<?

 function actor_name($last,$middle,$first) {

 // because we have so many different name combinations, write out a string

 // that does capitalisation and the like properly (hopefully)

 // ex: actor_name("ANGELO","d'","Jean-Pierre") = Jean-Pierre d'Angelo



  // strtolower() everything because ucwords() doesn't work on mixed case

  $last=strtolower($last);

  $middle=strtolower($middle);

  $first=strtolower($first);



  // split hyphenated names so we can ucwords() them

  if (strpos($last,"-")) {

   $lasthyphen=true;

   $last=ereg_replace("-"," ",$last);

  } else { $lasthyphen=false; }



  if (strpos($first,"-")) {

   $firsthyphen=true;

   $first=ereg_replace("-"," ",$first);

  } else { $firsthyphen=false; }



  // if the "middle" name doesn't end with an apostrophe, add a space and

  // lowercase it just in case someone's mis-typed it

  if (!strrpos($middle,"'")) {

   $middle.=" ";

  }



  $last=ucwords($last);

  $first=ucwords($first);



  if ($lasthyphen==true) { $last=ereg_replace(" ","-",$last); }

  if ($firsthyphen==true) { $first=ereg_replace(" ","-",$first); }



 return htmlentities("$first $middle$last");



 }



?>



Thing is, I'm getting bizarre behaviour where some characters become 
modified in a way I don't like - in particular, when the letter L follows 
an E with a diaresis (Raphaël, for example) it becomes upper case. 
Suggestions, anyone?



And if anyone wants to make that code shorter and more readable, I'd 
appreciate it greatly. :-)

i tried the seggestions you guys had

and i came up with one more question

does the session cookie.cookie_lifetime have anything to do with the amount

of time that session variables can be stored

the session.use_cookies is on and register.globals is turned on

however session.cookie_lifetime is set to 0

so would this affect the session variable lifetime?

Not sure about the correct terms in English, sorry ...

But to answer your question:
$pdag = "d".str_replace("-","",$premieredag[$i]);

where $premieredag is a date in form "2002-11-28".

So $n is then an index in the array that $pdag refers to.

But either way, writing echo(${$pdag}[$n]); got me the array contents as
desired ... so thank you. Now I can finally finish this thing ...

Thx

Hello, 

I'm displaying the content of a mysql table with autoincrement index. I want to be 
able to select the each row from the table using the check boxes. In order to do that, 
i want to assign to each checkbox the name=index of selected row. 
I assign to the checkboxes the value of selected id, but I can't retreiveit later for 
further processing. My code looks like this

 $query = "SELECT * FROM reclamatie";
    $result = mysql_query($query) or die("Query failed");

    /* Printing results in HTML */
 
 echo "<table border=1>"; 
    echo "<tr><td></td><td>ID</td><td>Subject</td><td>Open</td><td>Close</td></tr>"; 

     while($row = MySQL_fetch_array($result)) { 
         echo  "<tr><td><form><input type=\"checkbox\" method=\"post\" 
name=\"{$row['id']}\"></form></td>"; // ??????????
            echo "<td><a href=\"lowerframe.php?id={$row['id']}\" 
target=\"lowerframe\">{$row['id']}</a></td>"; //for other purposes, it works fine
            echo "<td>{$row['subject']}</td>"; 
            echo "<td>{$row['open']}</td>";
   echo "<td>{$row['close']}</td></tr>";    
        } 
        echo "</table>"; 

Any sugestions if i want to use forms, something like



<form method="post" action="selectare.php?id=$row['id']>
<input type="Submit"  value="Trimite" >
</form>



Thanks, Adrian

It looks like your naming it as a number, which won't work for PHP. You
want to name all of your checkboxes the same, with a [] on the name to
make the results an array in PHP.

... name="id[]" value="{$row['id']}"

Then, you'll have $_POST['id'][x] as an array in PHP. Only the
checkboxes that were selected will be in the array, from zero to however
many were checked. The value of $_POST['id'][x] will be whatever was in
the value="..." part of the HTML checkbox...

If you have access to a database on your server then you can do the
following:
- user logs in to site (user enters unique username and password)
- once in they will be displayed with the 3-6 Questions
- after they answer the questions they hit submit which sends it to a PHP
script
- the PHP script will check a table in the database for the username and
increment a counter
- then if the counter is less than 10 then validate questions for right
answer, .....then you understand the rest

hi,

which is faster; filling two array elements with two values, or making a two 
dimensional array to handle the two values in one element ...



which is better for Memory usage as well ?



(considering that both of them serve well in my situation)



thanx in advance



Regards,

Khalid Al-Kary

The user's choice is made from a drop down list of available items,
prior to running the routine itself.  The choices are predetermined
and kept in a personal table to be called by the routine.  This part
is finished to the point of putting the needed column names at the top
of the input columns on the form.  The choices are fixed spellings to
match formula if-then's, etc.   The use is for data manipulation and
so proper tracking of name/data is important in that regard, but the
final output figures go to the same categories in all cases so those
tables are fixed.  

The personal list table is to be called on the action page for keeping
the arrays in their proper order and usage.  The original idea was
that the list would be used somehow for creating the required
$_request's etc. 

But as you say, the tricky part is the naming of the columns, as we do
with the 'basic' column arrays.  I don't know if this can be done.
Thought it might be possible with 'dot' adds of functions or some such
to command lines built on the fly but haven't been able to make it
happen.  

But putting together what you and others are saying is giving me good
thoughts. :-)   Although I am still not sure how to code all of this,
much less express it, I am getting the idea that all 'columns' would
have the same array name and that the position of the data within that
single array will be the determining factor as to where it is applied.

That is if we need 3 user columns and 4 rows we will end up with a
single array of 12 values...  The three columns' fields would be
arranged as 1-4-7-10, 2-5-8-11 and 3-6-9-12.  

That should work nicely.  The column name list determines the number
of fields per row and the rest is automatic.  Perhaps I was going off
the deep end before but this method seems much less involved.  Anyone
see a problem with doing it this way?  

Many thanks to all and I apologize for the verbosity.  

Floyd

(Thanks to all who've replied about the streaming
audio. Haven't had a chance to respond or anything
yet.)

Here is a problem I'm having similar to somethnig
someone just posted, but not quite the same. I'm not
toooooo experienced with the intricacies and
complications of arrays, but I have a bunch of fields
like this for a magazine organizer (best way to put
it, I guess):

$issuenumber[]
$issueheadline[]
$issuewriters[]
$issuemonth[]
$issueyear[]
$issuedescription[]
among other fields.

I would like to store this all in one multidimensional
array, like
$issue->number[]
$issue->headline[]
etc.

What is the syntax? I'm bumbling around right now.
Also, if I sort() the array by number, would the rest
of the fields be properly sorted? I assume so, but
don't want to find out the hard way that it doesn't.

Dear all ,
 Hello ! I am a student and going to write a suit of programme . The
producers as follow

 producer 1.
 User A add an new appointment A ( "open Winamp at 2:30 on computer B")
through IE in his local computer A .

 producer 2.
 Computer A send the message to server A through http . The Servlet /
ASP.net which locates on server A receives the message and send message to
computer B (IP or domain name of computer B is given , named
"www.computerB.com") .

 producer 3.
 Computer B receives the message from server A through http at 1:01 . It is
expected to implement the new added appointment A ( "open Winamp at 2:30 on
computer B" ) at given time .

 I know what to implement the producer 1 and 2. However , I don't know how
to implement producer 3. Do you mind to tell me how to make a PHP programme
to execute a centian routine at a given time ? Thank you !

Hi Jonathan,

PHP doesn't have anything built in that'll do this for you (at least,
nothing that I'm aware of). 

The best solution is to call your script from your OS's scheduler - cron
under unix/linux, or task scheduler in Windows. I usually trigger the script
with lynx and pipe it to /dev/null, but if you have PHP compiled as a
standalone instead of a server module, you could call it directly.

Cheers
Jon

Hello

Is it possible to detect with PHP whether an email sent using the PHP
'mail' function has bounced back or has not been delivered?

I currently all ready check the email address using the 'ereg' function
before the mail function is called, but this only checks the format is
valid beforehand.

Yes, and No!

If you use the ReturnPath header SOME/most email servers will bounce msgs
that they can't deliver to an actual mailbox back to you (others drop such
msgs onto an Admin somewhere, lose them in the ether (the msgs not the
Admins...) etc, etc). Accordingly, use a distinct address for this/email
filing rules.

Opt-in email schemes which send a welcome/confirm email to new customers do
so for this reason - the only way to verify an email address is to use it
(and get some feedback from the addressee).

Of course, once you have 'located' a new user, you still have to cope with
those who close email accounts without advising you...

It's a wonderful world!

Hi,

If you're using PHP on a unix/linux with sendmail you can set the
envelope sender via the 5th parameter to the mail function,
additional_parameters.  Normally the envelope sender is the username
that your web server process runs under (usually "nobody" if you're
using Apache), but you can set it to either your email address or an
email address you have setup specifically to catch bounces.  Example:

mail('[EMAIL PROTECTED]', 'Test email', 'This is a test', '',
'[EMAIL PROTECTED]');

Most MTA in existence will route DSNs to the envelope sender, not the
From: header.

Note that sendmail will add an X-Warning header if the user your web
server runs as isn't considered a sendmail "trusted user".  The
quickest way to fix this (on Redhat machines anyway) is to put the
username in /etc/mail/trusted-users.  Other systems and sendmail
installations may differ, so YMMV.

HTH...

Wow. This goes way beyond simply printing
multidimensional arrays. Here's some sample data:

$issue[]["number"] = "number";
$issue[]["headline"] = "headling";
$issue[]["writers"] = "writers";
$issue[]["list"] = "list";
$issue[]["senttosubscribers"] = "0";
$issue[]["month"] = "05";
$issue[]["year"] = "2003";
$issue[]["description"] = "description";

What I need to do now is count(), sort() by number,
and loop through this array.

I read that PHP is screwy when counting and sorting
multidimensional arrays, but they *have* to have come
up with a method, right?

if [$number] is unique, use it as the key:

// $issue[]["number"] = "number"; -- removed
$issue[$number]["headline"] = "headling";
$issue[$number]["writers"] = "writers";
$issue[$number]["list"] = "list";
$issue[$number]["senttosubscribers"] = "0";
$issue[$number]["month"] = "05";
$issue[$number]["year"] = "2003";
$issue[$number]["description"] = "description";

then sorting by the the number will be simple (ksort)

Thanks to Paul and Marek for some ksort() advice. I'll
try that out as soon as I can count() these buggers.

A little more info on my count()ing.
I have $issue[0]["number"] to $issue[x]["number"] just
like any other multidimensional array (we'll call them
m-arrays for simplicity).

If I try to count($issue), I'll get all instances of
my array (instances?) mltipled by the number of
elements (don't know if this includes NULLs or not,
don't have NULLs). If I try to count($issue[]), it'll
give me the number of elements (8), which is also not
correct. If I try to count($issue[]["number"]) it says
I can't pass that to the count() function (which is
logical). But it leaves me with no way of count()ing
my instances.

My problem is I need to loop through these. So I can't
just assume that the count is count($issue[]) divided
by 8, because that won't work in a for loop. I suppose
I could just iterate through my for loop in jumps of
8, but that seems really hacky and unintuitive to
whomever has to figure out my code when I'm gone.

If there's a kcount(), I'm all for it. :)

<<if [$number] is unique, use it as the key:>>

Yeah, I'd thought of that except there's no guarantee
that it will be unique.

Plus, it makes it harder to go through with a simple
loop because $number really isn't guaranteed to be
numeric (okay, so I have to change the name). Plus, it
may not even start from 0, For instance, it doesn't
have to be from 1-10, it could be from 75-85.

You don't need sequential numbers as your key.
Take this example:

/*** define some values ***/
$fruits['apple']['color']=$color;
$fruits['apple']['diameter']=$x;
$fruits['orange']['color']=$color;
$fruits['orange']['diameter']=$x;
$fruits['grape']['color']=$color;
$fruits['grape']['diameter']=$x;

/*** Grab the keys ***/
$fruit_types = array_keys($fruits);
$count = 0;
while ($count < count($fruit_types))
{
    $fruit = $fruit_types[$count];
    $color = $fruits[$fruit]['color'];
    $diameter = $fruits[$fruit]['diameter'];
}

<? include ('./header.php');
$query="select prodid, title FROM fatbeats_prod";
$result= mysql_query($query);
$names= mysql_fetch_assoc($result);

$query1="select prodid, price from fatbeats_prod";
$result1=mysql_query($query1);
$prices= mysql_fetch_assoc($result1);

 while (list($key,$val) = each($qty)) {
 $shoppingCart[$key] = $val;
}
while (list($key,$val) = each($shoppingCart)) {
 $currentName = $names[$key];
 $currentPrice = $prices[$key];
 echo "You added $val of $currentName to your cart, which costs
$currentPrice euro. <BR>";
}
 include ('./footer.php');
 ?>

What i need is to declare the arrays $names and $prices
And select the prodid as key and the title as val how can I do this?

I tried "select prodid as key, title as val
but that doesnt work.

thx for any help
