[PHP] E-mail Gateway

[Jason Williard]

I am in the beginning phases of developing a support system.  I would
like the program to be able to receiving and process e-mails.  However,
I am at a loss as to where to start.

The main roadblock, at this point, is how to best receive and process
the e-mail.  I have looked at 2 options.

1) Use a cron job to execute a php script every x minutes.
2) Create a script where mail can be piped to.  This is a method that I
have used previously with a cgi app called PerlDesk.

While I could develop the first option, the second option is the method
of choice, but I have no clue how to implement that.  Would anyone
happen to have any suggestions on where to start?  Perhaps, someplace
where I could go for further research?

Thank You,
Jason Williard

You can't use "!" because it's not a valid special character in regular
expressions.  It's really hard to craft do-not-match-this-word patterns.
You're better off separating the two pieces of logic.

$arr = array(
"abcd - rst",
"abcd - uvw",
"abcd - xyz",
"foobar - rst",
"blah - rst",
"googol - uvw"
);

reset($arr);
while (list($key, $value) = each($arr))
{
if (substr($value, 0, 5) != 'abcd ')
{
$arr[$key] = ereg_replace('^(.*) - .*$', '\1', $value);
}
}

print_r($arr);

Although you could use CLI PHP for this, I would use Perl or even better, C. 
PHP is really meant to run via a web browser and what you're talking about is 
all backend code. Look into playing with procmail and Perl or C.

Possibly have to do a if statement, ereg for the abcd and then if ture, do 
your ereg replace? I can't logically think how that would work in one regex, 
since you want to match first and then replace...but my regex skills aren't 
top notch either :)

As usual, if you can think of a question, chances are it has already been 
asked and answered before. So your first port of call is either google or the 
list archives. "php process mail" would be an obviously good search term.

[PHP] Search For File

[PHPDiscuss - PHP Newsgroups and mailing lists]

Hello,

I am trying to write a simple application using PHP on a Windows 2000
server.  There is one text box for input and one search button.  Basically
the user would input a file name (for example "help.pdf") and then the php
script would search a directory (for example "c:\help\") and subfolders
for that file.  If the file is found, I would like to automatically
display the file using Adobe Acrobat.  Ideally I would like to be able to
use wildcards and obtain a list of results linking to the files.  Any
ideas on a good way to do this?  I am mainly interested in how the search
should work.

Thanks

Jamie

Ummm, I've been using PHP for shell based scripts for years now. Are you
telling me all the re-usable power of my InterJinn web scripts is
foolish and that I should recode them as Perl or C? Eeeek, I though the
whole point of CLI was to empower non-web application programming with
PHP.

Cheers,
Rob.

The following is untested:

---

foreach( $myArray as $id => $entry )
{
if( ($pos = strpos( 'abcd' ) !== false && $pos === 0 )
{
$parts = explode( ' - ', $entry );
$myArray[$id] = $parts[0];
}
}

print_r( $myArray );

In answer to Point 2...

If you are in a position to edit your 'aliases file' you can feed email to a
program using PHP quite easily. I am doing it and works quite well.

So, 1st, edit your file (generally in /etc/mail/aliases) and add the line:

testit: "|/usr/local/bin/php /path/to/your/php/file/processmail.php"

(making sure this is the path to php etc)

Below is an example how to capture the mail, the following simply reads the
email into $buffer and emails it, this should hopefully point yu in the
right direction...

You could use the filesystem functions and read the directory's contents

My mistake in coding is that I always start with the parts I know I can do,

partly because my chef keeps inventing new functionality, but mostly 
because I did not know how to write a proper plan (i did try).
I tried my own way, i tried Unified Modeling Language (UML) , but that was 
a bit too heavy for a one-person coding project.

Right now I am rigourously reorganising the whole mess, which would not 
have been necessary had I made better plan.
The most simple rule is: divide functionality. Do not mix logic with 
presentation. Have your SQL part, your logic part and your presentation part.
And of course add loads of comment while you are working. Best for the 
thinking process is to first make comments of the steps you want to make, 
and only then add the code. I noticed that while writing the comments, I 
would adjust my plans.

Look for the following line in your Apache configuration file and change
it thusly:

AddType application/x-httpd-php .php .html

Thank you, that was it. Boa can't run php directly. So i made php files
executable and added '#!/usr/bin/php4' at the beginning of the script.
Instead of that I should have used the cgi version, as you suggested,
which was /usr/lib/cgi-bin/php4.

Well, I've, and I also have to say that the XML-support in PHP lacks

pretty thin on this chapter...

For example, I've the following XML:

Here I thought that the startelementfunction should be called upon 
every start tag, the character_data_handler on every text string and 
the endelement function on every endelement.

But what seems to happen is that the character data handler is called 
to randomly number of times, and if I output the current element every 
time it gets called I get the following output for the xml above:

[PHP] sorting an array of regexes

I want to sort it comparing to the
 character lenght of a regex. For example
 [wh]ood is 4 characters, moon is 4 characters.
 There are only letters of the alphabet and
 letter ranges present in those regexes. I
 want the "longest" ones first.

How would you write the sorting function?

This might be the most functionally correct, although it's definitely
not the fastest route.

function re_len($pat)
{
return strlen(preg_replace('/\[[^]]+]/', '_', $pat));
}

function re_sort($a_pat, $b_pat)
{
$a = re_len($a_pat);
$b = re_len($b_pat);
if ($a == $b)
{
return 0;
}
return ($a < $b ) ? -1 : 1;
}

usort($array, 're_sort');

BTW, re_len() will bomb on certain oddball patterns with strange ranges.

I think you meant:

/\[[^\]]+]/

as regex ;) Not sure, but I think one more block-bracked needed to be
escaped ;)

[PHP] How to get the key of a specific index of array?

[PhiSYS]

How to get the key of a specific index of array?

It seems that key($_POST[$i]) is a wrong syntax.

I've worked around like this:

  $allkeys = array_keys($_POST);
  $allvalues = array_values($_POST);

  for($I=3; $I < count($_POST); $I++) {
echo $allkeys[$I];
echo $allvalues[$I];
  }

But I think that it will use the double of memory. And that won't be good 
for long arrays.
So the cuestion is... Is there a PHP function to do this?
I successfully did it with ASP using Request.Form.Key(I) but I really do 
prefer PHP when I'm free to choose the language.

Or how can I move the internal array pointer to a specified position to 
be able to use the key() function?

As you probably noticed I started the $I counter at 3 because the first 3 
values of the array will be used for other purposes. That's why I don't 
want to use a foreach().

Thank you all!

First of all, you said to use the first three values of the array for anoter
reason .. well the, what I'd do is this:

$FirstThree = array_splice($_POST, 0, 3);

Which will give you the first three elements of the array, and leave you
with a $_POST array you can do foreach with.

Second, to manually loop through an array, use:
http://nl.php.net/manual/en/function.prev.php
http://nl.php.net/manual/en/function.next.php
http://nl.php.net/manual/en/function.current.php
http://nl.php.net/manual/en/function.reset.php
http://nl.php.net/manual/en/function.end.php

Third, don't rely on the order your array elements are given to you by post
data. Rather just use foreach() and (ignore|do something else with) the
key-value pairs you don't want for this thing.

Fourth, I hope I'm not spoiling Jay Blanchard statement on how uncredibly
great this online PHP Manual is since you could probably find all the
answers to array related questions right here:
http://nl.php.net/manual/en/ref.array.php

And all you other answers around here:

Subject: [PHP] [Q] Development Best Practices


All,

I'm not new to programing or web development but I am new to creating 
dynamic pages.

I've read through a couple books. I've worked through problems and 
exercises. Installed and configured the software a few different times 
in Win32 and OS X. At this point, I feel I have a good handle on the 
environment and lexical structure. What I don't have is a grasp on best 
practices. For real sites I'm a little confused on how to implement all 
this new knowledge. For example, I've got a site that was static with 
bits of CGI to PHP. I was going to generate all the HTML from a PHP 
script, but that turned into a mess. So I tried creating the pages is 
mostly HTML with little bits of PHP. Placing the logic in another file 
and linking the two pages. I'm not really sure if that is the best 
approach.

My question, how do you guys build your pages? Do your scripts generate 
all the HTML? I'm looking for tips and resources. Remember for my first 
site I've embarked on a fairly large site. Code maintenance will be an 
issue for me as I need to enhance and fix it later on.

Thanks guys!

While writing PHP code you put your body in risk of getting "work related
problems". Manage your PHP Code Writing sessions so that you do not spend
too much time behind your screen. Read about PHP in a book too sometimes, or
print several pages of the online PHP reference manual.

It's mostly about asking the right questions to Jeeves.com. Make sure you
don't ask him HTML specific questions, since he tends to give you false
answers on that

 Thank you, that will certainly work :8]. Does
 anyone have any thoughts how to make it faster? It is
 not VERY critical, because the calculation will be
 done only once, at initialization, but...well, you 
 know :8].

* * *

 How about...if I count the number of ']'
 in string and then add it to the strlen - (the
 number of ']' x 2)? There are no [ nor ] in these
 except in the character range parts. Does that
 look faster than applying regular expression?

This is a model request for help - you've removed all code that isn't
directly related to the problem, you've written a test script, and your
question is succinct.

Unfortunately, it's not about PHP.

Having said that... maybe you should turn your pop-up blocker off while
testing pop-ups?

(This is one of the myriad reasons why pop-ups are a bad design decision,
BTW.)

Re: [PHP] file descriptor problem with tcpclient

[Raditha Dissanayake]

Hi Bill,
Bill of Bill's qmail toaster I presume.Your article was pretty good.
I have seen a few cases where sessions gave problems when the session
tmp dir wasn't set in php.ini Not sure if that's the cause of your
problem though.

Any idea why this descriptor is not accessible?  Here's what I'm

Ok, I have discovered that this ONLY occurs when I have started a

[PHP] An array as an element of a function

[Jeff McKeon]

Is it possible to pass an array as an elemtent of a function??

Something like this:

$array1=array(1,2,3,4);
$array2=array(a,b,c,d);

Function Somefunction($var1,$var2)
{
someprocess using $array1 and array2;
}

Somefunction($array1,$array2);

Or does something special have to be done?

Hi,
What do you mean by element of a function? usually functions take 
parametes (also known as arguments). elements are members of an array. 
In other words a collection of elements make up an array.

Do these change all the time or are they rather static?  I would
suggest using this routine to generate the list to be used in your
program, instead of doing this on the fly.

Are you /certain/? A software firewall maybe? Are you at a business site
where your sysadmin might be blocking junk? Which browser are you using?
Have you tested in other browsers/on other machines?

The following code works fine here (IE, Opera, Moz):




function boo() {
window.open ("http://www.google.com/";);
}



why does no window open?



This is well off-topic though. If you don't have any luck, contact me

[PHP] Question about empty();

[John]

Hi all

This function I don't get at all, I hear all the time, "if you want to
practice smart coding then turn register globals off, and be sure you keep
query data out of your script that is not set or defined with something
expected". So why would there be a function that returns true or false, $var
is empty even if $var is not defined! Now I know you can do bool(), but the
function name (empty()) really states one thing "Does it have a value or (!)
not have value" and not "Does have a value or does (!) not have a value and
may be undefined too!" If you don't want to correct it then at least give a
warning if the $var being tested is undefined!~

This is a function that does more than it should do, and in this case more
is bad!

C, Ya...

It's just a shorthand that helps avoid tests like the one below, common in
a user input validation situation:

(!isset($_POST['var']) || ($_POST['var'] == ''))

Instead, you can use:

empty($_POST['var'])

This statement demonstrates a lack of understanding on your part. PHP is
free. Completely free. It costs nothing. Nada, zilch, zero. It is not
owned by any company or induhvidual. There are acknowledged leaders in
the community.

Zend does not control PHP. Zend has just invested a lot in the
technology. If PHP went away tomorrow Zend would focus their core on
something else. Likewise if Zend went away tomorrow PHP would continue
to grow and evolve.

Putting an encoding feature into the core of PHP would require actions
by those developing PHP, which you can take part in. Right now there are
several encoders available from other sources and it is up to each
induhvidual/team/organization to decide a. do we need to encode? and 2.
which encoder do we want to use? Just like you can choose to use MMTurke
or Zend Encoder or another encoder.

What is so hard to understand about this?

[PHP] Arrays and performance

[Kim Steinhaug]

Something Ive wondered about as I started working with XML.
Importing huge XML files, and converting theese to arrays works
indeed very well. But I am wondering if there are any limits to
how many arrays the PHP can handle when performance is accounted for.

Say I create an array from a XML with lots of childs, say we are
talking of upto 10 childs, which would give 10 dimensional arrays.
Say we then have 10.000 records, or even 100.000 records.

Will this be a problem for PHP to handle, or should I break such
a prosess into lesser workloads (meaning lesser depth in the array)?

Anyone with some experience on this?

Re: [PHP] Arrays and performance

[Raditha Dissanayake]

Hi,

I belive PHP should be able to handle it but it's a bad idea. The reason 
being your app will not scale. Because if you script consumes 2mb of 
memory on average, 100 users accesing it at the same time will be 200Mb. 
Of course if you expect only a small number of users it does not matter.

The biggest XML job i have handled with PHP is parsing the ODP RDF dump 
which is around 700MB. Obviously arrays are out of the question in such 
a scenario, even though only one user will be accessing the script at a 
given moment. the ODP dump has a couple of million records

Re: [PHP] Arrays and performance

[Raditha Dissanayake]

hi,

In fact i had to handle the ODP dump on two occaisions the first time 
the results went into a mysql db, the second time it went into a series 
of files.

On both occaisions i used SAX parsers. DOM would just roll over and die 
with this much of data. I placed code in the end element handler that 
would either save the data into a db or would save it to a file. In 
either case i only kept the data in memory for a short period. ie from 
the time the start element was detected through the character data 
handling until the end element was detected. (Obviously  i am not 
talking of the root node here :-))

During the whole process you barely noticed the memory usage, however 
the disk usage still went up of course. Reading from disk 1 and writing 
to disk 2 does wonders!

please let me know if you need any further clarifications.

[PHP] Front page validation to PHP

[Graham Barlow]

We use Frontpage to create forms and to add validation to data entry.  These
have been saved as html and put on a hosted server running apache and PHP.
They work fine.
 
Now we have added cookies using PHP code to the forms and renamed them .php
rather than html.
 
The cookies work fine so does data capture, but the validation no longer
works. Hence an enquirier can simply press submit and the form gets
submitted with no data if they have chosen not to enter any information.
 
What do I need to do to our Frontpage forms to ensure the validation works
again and we can force data to be entered.
 
Any ideas welcome.
 
Thanks, Graham

I haven't used frontpage in probably 2 years so my memory may be a
little foggy. But iirc frontpage uses some kind of proprietary code to
do that form validation. You'll basically have to rewrite the forms and
use regular server side validation and/or javascript (server side is
better for data security). Otherwise maybe it's possible to have
frontpage extensions (I think that's what the form validation is using)
and PHP work together on the same file???

Maybe you can tell php to parse .html files and rename all your files
back to .html?? I know php will parse .html files if you tell it to but
I don't know if there will be a conflict with frontpage extensions or
not.


HTH,
Chris.

[PHP] Assigning command line vars in script

[PHP] mkdir with PHP 4.3.4 and IIS 5.0 on Windows 2000

[Dang Nguyen]

I have a peculiar problem in one of my scripts.  I cannot mkdir from the
script, but from a test script, the same exact code works.

test.php contains:
\n";

mkdirs($directory,0755);



$dir_object = @dir ($directory) or die ("Could not open a directory stream
for $directory");

print_r($dir_object);

$dir_object->close();

?>

I have another script that takes some input from the user, namely to be a
new sub-folder to create on the destination directory.  Just to eliminate
the possibility that the code from my script is not the problem, I commented
out everything that had to do with what I really wanted.  In its place, I
substituted the above code from test.php.  When I call test.php, the
directory is created fine.  However, when I execute my problematic script,
which now contains the exact code, I get

Attempting to mkdir
Could not open a directory stream for \\seint16\TechComm\Ceos\Dang\

This is quite puzzling, since the exact same code should work in both
scripts, but it's not!  Any help, please!

Thanks,
Dang Nguyen

RE: [PHP] mkdir with PHP 4.3.4 and IIS 5.0 on Windows 2000

In my case, I've created a function called mkdirs that recursively checks
and does a mkdir on a given path.  So, if any of the folders in a given path
don't exist, then they will get created.  I include this at the top via
"include('func/mkdirs.php');".  I've used this mkdirs function in other
scripts, and I know it's working fine.

mkdirs.php contains:
 1) {
  $pStrPath = dirname($strPath);

O.K.  I am just now experimenting with the CLI PHP and have another

before the imap_open, but still the same behavior.  Any ideas?

echo "Connecting to $server: $mbox ...\n\n";
$conn = imap_open("{" . $server . ":143/notls/norsh}" . $mbox, $user,
$pass);

echo "Receiving messages ...\n\n";

Mi portugues is very rusty, but I think the solution is:

and then print $url where ever you want.  Notice the quotes and single

You can learn more about this on php.net/urlencode

Nope.  My pattern is legitimate.  Within a range, if the first character
is a closing-square-bracket ']', it is treated as the literal character
and not as the end of range.  If the range starts with a negation '^',
then the same rule applies to the second character.

This is also a sad indication that I really know my regular expressions,
or I need a vacation.  :-)

[PHP] how to trap eval error?

[david]

Hi, 
i am new to this list as well as to PHP. i am in a situatin where i want to 
eval a string like:

eval('$return = $function($input);');

where $function is a string specify a function to call and $input is the 
input parameter for the function. $return is just whatever is returned by 
the $function. my problem is that if $function is NOT defined anywhere, i 
got a fatal error like:

Fatal error: Call to undefined function: ... 

does anyone who how to trap this error if it can be trap at all? what i have 
done so far is something similar to:

set_error_handler('myHandler');
eval('$return = $function($input);');

that doesn't seem to work at all as 'myHandler' is never called. i have 
alose tried to check $php_errormsg but that doesn't seem to be helpful as 
well. as a last resort, i tried:

error_reporting(E_USER_ERROR | E_USER_WARNING | E_USER_NOTICE);
set_error_handler('myHandler');
eval('$return = $function($input);');

that does seem to make the error stop appearing but my handler is still not 
called. any idea?

thanks!

thanks for the tip but i am sure you mean:

eval("\$return = \$function(\$input);");

otherwise the variables gets expanded before they get to eval and i end up 
with a syntax error. i found a solution (hopefully) with:

if(function_exists($function)){
eval('$return = $function($input);');
}else{
// function does not exists
}

which works quit nicely for now. not sure if that's a good thing to do.

thanks!

[PHP] PHP 4.3.1 (Suse 8.2 RPM) and LDAP problem

[Patrique Wolfrum]

Hello,

My PHP-problem is, that I can't bind to a LDAP-Server, although 
ldap_connect seems to work. The script is intended for an 
authentification of web-users (which enter their username and password) 
by sending this data to a central ldap-server.
Openldap 2.1.12+Libs (Suse RPM) and OpenSSL (Suse RPM) are installed.

On the server which acted as "authentification server" (Redhat 9.0 (php 
4.2.2)) the same script works quite fine.

The firewall we use is configured with the same settings for our main 
server which I used for the "authentification server", so the connection 
should work from that part. The ports 389 and 636 are free if the 
connection goes to one of the two ldap-servers mentioned below.

My script looks the following way:

---

$uid = $HTTP_POST_VARS['uid'];
$ldappass = $HTTP_POST_VARS['passwd'];
$basedn = 'dc=xxx, dc=de';
$ldaprdn  = 'uid='.$uid.', ou=xxx, dc=xxx, dc=de';
$ldapserver1 = 'ldaps://xxx.xxx.xxx.de';
$ldapserver2 = 'ldaps://xxx.xxx.xxx.de';

// connect to ldap server
$ldapconn = ldap_connect($ldapserver1) or die("Es konnte keine 
Verbindung mit dem LDAP-Server aufgebaut werden. Versuchen Sie es bitte 
spaeter nochmals");

if ($ldapconn) {

$ldapbind = ldap_bind($ldapconn, $ldaprdn, $ldappass);

if ($ldapbind) { 



Beyond the $ldapbind line, several attributes are requested from the 
LDAP-server and used for statistical-information.

The script works until it reaches the $ldapbind = ldap_bind line, then I 
get the following message:



Warning: ldap_bind(): Unable to bind to server: Can't contact LDAP 
server in //authenticate.php on line 22



Tests with ldap_error show the following results:

ldap_connect: A resource ID
ldap_bind: success

(The latter is the most confusing one for me)

I looked at the PHP-documentation and searched via google, but I could 
find any clue, which could get this script going again.

How can I further determine, why the ldap_bind doesn't work properly ?

Thank you very much in advance.

With best regards.

Yes, several of us have seen it, many times in fact. Imagine that.
Browsers, being the stateless wonders that they are, do not 'maintain'
the information. You have some choices through. Retrieve the variables
from the database, save them in a session variable and retrieve them
from there, or do some other imaginative method of 'maintaining' the
variables until you are done with this particular group of variables.

I invite you to STFW and STFA for the answers to your dilemna. Have a
pleasant day and happy coding!!
