Zend has a lot of products, though, and there maybe might be one designed just to secure your PHP source... I kinda lost track lately, with all the options out there. Err, anyway, I just really wanted to say that virtually every Zend product has been so routinely mis-represented by what it does that the amount of mis-information out there is probably larger than the amount of correct info. Read Zend's website product descriptions first, and ignore forum/mailing list comments until you're clear on what the product does, and doesn't do. That will help you separate the patent falsehoods from useful info, and winnow down your reading by a factor of 3. -- Like Music? http://l-i-e.com/artists.htm -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

The used MD5 hash tells you they are re-submitting the exact same form. Now, if the real problem is that the user has a fresh new form, and fills in the same data again by hand, then there are only two possibilities: 1. In the real world, they actually NEED two of the "same" thing in the database, and your application should allow it. 2. In the real world, users are likely to lose track of where they are in their data entry, and you need to provide them the context to help avoid that. When you go back to 1) present a message like "added blah blah blah" at the top of the screen. Now they *KNOW* they just did blah blah blah, and can move on to blah blah bleh. Data entry is a sucky job. Make it nicer for them, eh? You STILL need to code for the dual entry, and do something intelligent when they mess up, but you can improve efficiency and decrease errors (where 2 not-quite-the-same-but-really-are-the-same entries pass your tests) if you make your application nicer to the user. -- Like Music? http://l-i-e.com/artists.htm -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

Your best bet would be to use PHP to QUEUE the emails up, and let your mail sending software (sendmail, qmail, elvenmail) worry about load and timing. You may also want to consider having the web-based application simply set a flag/indicator somewhere which tells PHP that it's time to queue up all 100 emails. Then the end user won't even have to wait for 100 emails to get queued up in line. They only have to wait for the flag to get set which should take, like, less than one second. There are also innumerable PHP mail classes "out there" to make sending email easier. http://phpclasses.org has some, I'm betting PEAR has some, and you could Google and find a thousand more. -- Like Music? http://l-i-e.com/artists.htm -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

Where is your error checking?
I don't know much about that fancy new stream stuff, or the XML crap, but
you've got zero (0) lines of code in there to do anything useful when the
functions fail.
If you ask the functions nicely, they almost always tell you EXACTLY what
went wrong.

Re: [PHP] Refresh (F5) adds another SQL record.
As a last resort, I may have to do that, but that is by no means the
preferred method. I want to keep database access to a minimum.
I thought by this time this problem would have had a standard solution. It
would be nice if PHP had a function like refreshed() so one could do ... if
(!refreshed()) { ... } ..., but I guess not.
Thanks for your input.

I looked for such a message and the only thing I can find is as follows:
1) _SERVER['HTTP_ACCEPT'] and _ENV['HTTP_ACCEPT'] and change to "*/*", but I
don't know if that is the case for all browsers, do you know?
2) _SERVER['REDIRECT_UNIQUE_ID'] and _ENV['REDIRECT_UNIQUE_ID'],
_SERVER['REMOTE_PORT'] and _ENV['REMOTE_PORT'], _SERVER['UNIQUE_ID'] and
_ENV['UNIQUE_ID'] change, but I don't think the values are predictable,
especially between browsers.
Do you know of a specific message to look for and is that message the same
for all browsers?

Updating the array in the shopping basket -- not so easy !!??!!
A shopping basket should be able to add and delete items (done)
You should be able to delete the whole basket (done)
Now I need to be able to update quantity - I've spent at least 5 or 6

Any hints would be good.

It appears that your overall problem is a misunderstanding of how arrays
work in PHP and how easy it is to manipulate them.
First:
> if (session_is_registered('ses_basket_items')){
In general, for practical purposes (if PHP is installed using the
recommended default setup, ie register_globals disabled),
session_is_registered() is deprecated and should not be used. Use:
if (isset($_SESSION['ses_basket_items'])) { ... };
Second:
> if ($action == "empty")
> {
> while ($ses_basket_items > -1)

> $ses_basket_items--;
> }
> }
You seem to be using multiple single dimension arrays to store your
basket
details. That is not the optimal way of doing things. You should have a
*single* multi dimension array, there are many ways to do this, here's a
couple:
1)
$basket[1] = array('name' => 'name of product',
'id' => 'product id',
'price' => 'price of product',
'amount' => 'quantity required');
$basket[2] = array('name' => 'name of product',
'id' => 'product id',
'price' => 'price of product',
'amount' => 'quantity required');
2)
$basket['a_product_id'] = array('name' => 'name of product',
'price' => 'price of product',
'amount' => 'quantity required');
$basket['another_product_id'] = array('name' => 'name of product',
'price' => 'price of product',
'amount' => 'quantity
required');
OK, so how do you operate on them? In the examples below 2 forms will be
given corresponding to how you defined the arrays as per above.
To remove an item:
1) unset($basket[n]); // where n is an integer
2) unset($basket['product_id']; // if product_id is an integer
// then you don't need the single-quotes
// note that also applies when first
// define the array, ie:
// $basket[product_id] = array(...);
To change an attribute, eg the amount:
1) $basket[n]['amount'] = 5;
2) $basket['product_id'] = 10;
To display an attribute, eg price:
1) echo $basket[n]['price'];
2) echo $basket['product_id']['price'];
When playing around with arrays, print_r() is your friend, use it
liberally.

Did you try building any complex data structures? You could have whipped out something to test pretty quickly. The quick answer is, 'Yes'. The longer answer is: cut-and-past the following into a script and see what you get: $cds = array( 'element1' => array( 'string1', 'string2', 'string3' ), 'element2' => true, 'element3' => array( 'subelement1' => array( array(1, 2, 3), 2, 3 ) ) ); var_dump($cds); You can create any complexity you want using nested arrays.

It appears that your overall problem is a misunderstanding of how arrays
work in PHP and how easy it is to manipulate them.
First:
> if (session_is_registered('ses_basket_items')){
In general, for practical purposes (if PHP is installed using the
recommended default setup, ie register_globals disabled),
session_is_registered() is deprecated and should not be used. Use:
if (isset($_SESSION['ses_basket_items'])) { ... };
Second:
> if ($action == "empty")
> {
> while ($ses_basket_items > -1)

> array_splice ($ses_basket_name,
> $ses_basket_items, 1);

> $ses_basket_items--;
> }
> }
You seem to be using multiple single dimension arrays to store your basket
details. That is not the optimal way of doing things. You should have a
*single* multi dimension array, there are many ways to do this, here's a
couple:
1)
$basket[1] = array('name' => 'name of product',
'id' => 'product id',
'price' => 'price of product',
'amount' => 'quantity required');
$basket[2] = array('name' => 'name of product',
'id' => 'product id',
'price' => 'price of product',
'amount' => 'quantity required');
2)
$basket['a_product_id'] = array('name' => 'name of product',
'price' => 'price of product',
'amount' => 'quantity required');
$basket['another_product_id'] = array('name' => 'name of product',
'price' => 'price of product',
'amount' => 'quantity required');
OK, so how do you operate on them? In the examples below 2 forms will be
given corresponding to how you defined the arrays as per above.
To remove an item:
1) unset($basket[n]); // where n is an integer
2) unset($basket['product_id']; // if product_id is an integer
// then you don't need the single-quotes
// note that also applies when first
// define the array, ie:
// $basket[product_id] = array(...);
To change an attribute, eg the amount:
1) $basket[n]['amount'] = 5;
2) $basket['product_id'] = 10;
To display an attribute, eg price:
1) echo $basket[n]['price'];
2) echo $basket['product_id']['price'];
When playing around with arrays, print_r() is your friend, use it
liberally.

Re: [PHP] regex question
Murry's solution here is ideal since it only captures the single occurrence.
Since I want to use it for a preg_replace(), it is perfect.
A couple of folks sent this pattern [EMAIL PROTECTED]@[EMAIL PROTECTED]; but, it doesn't work because I
then have to remove the unwanted caracters on either side.
All it says is [not @[EMAIL PROTECTED]@] but, it captures the 2 characters on
each side.

Please ignore my last email re: your question. I realized that the negation
of the range containing the "@" would end up capturing unwanted characters.
As an alternative, try the following:
preg_match_all('/(?
$thing, PREG_OFFSET_CAPTURE);
print_r($thing);
Hope that's a little more relevant to your question.

[PHP] RE: regex question
I think there maybe a few ways to do this... One is
[EMAIL PROTECTED]@[EMAIL PROTECTED]
That basically says "find me the pattern where one non-at symbol is followed
by an at symbol followed by another non-at symbol"
So if you do
numMatch: 3
Array
(
[0] => Array
(
[0] => @
[1] => i@
[2] => [EMAIL PROTECTED]
)
[1] => Array
(
[0] => @
[1] => @
[2] => @
)
)
Well, where that fails is when you have @'s at the beginning or end of the
string and that's easy enough to do.. So that would mean three searches...
There's probably a way to integrate them into one without loosing integrity,
but it depends on what kind of regexp libs you have, I reckon. It also
depends on what you really are trying to do with this search. Consider
str_replace, strpos and strtr as well.

Carl

[PHP] Upload Files
I have a few interpretive questions on uploading files. There is the max_input_time, and the max_execution_time. I am uploading files and they continue to time out after a few minutes. Looking at the php.ini file from phpinfo() shows max_input_time set to -1 and max_execution_time set to 60. Does the max_execution_time have anything to do with the timeout, or is it all in the max_input_time? And does the "-1" value mean run indefinitely (until the file is uploaded)? Is there any function that will change that value? Any clarifications on this would be helpful. Stuart
[PHP] php addslashes etc
Hi, First of, sorry for the attachment. It is a screenshot of the output of the following code. It also shows the contents of the array data in question. I have the following piece of actual code: // $arrayData is the data in an array form $arrayData = ArrayIzeDbResult( $db2 ) ; // we want to capture the printed output ob_start(); $data = addslashes( serialize( $arrayData ) ); print $testdata; $printeddata = ob_get_contents(); // this next line does not work since the results of unserialize // is bool(false) ob_end_flush(); print "\nNumber, the first\n"; print_r( unserialize( stripslashes( $printeddata ) ) ); // however, this next line DOES work print "\nNumber, the second\n"; print_r( unserialize( stripslashes( addslashes( serialize( $arrayData ) ) ) ) ); I am trying to store the serialized array into a database (mysql) but on reading it out again, it cannot unserialize. This piece of code, even though it doesn't use the db, shows the problem perfectly. The other funny thing is that not all arrays break when I am doing this. I have quite a lot of similar arrays that work find when you do this.

I try to not restrict the way your users enter phone numbers or other types
of structured data. I wouldn't bother validating against ddd-ddd- unless
you also plan on validating (ddd) ddd-, ddd.ddd., +1 ddd ddd ddd or
any number of variations. Your best bet is to make sure that the number
contains 10 (or 11) digits:
$phone = preg_replace('/[^0-9]/', '', $phone); # remove non-numbers
if (preg_match('/^1?[0-9]{10}$/', $phone)) {
echo 'Valid';
}
To answer your original question:
if (preg_match('/^[0-9]{3}-[0-9]{3}-[0-9]{4}$/', $phone)) {
echo 'Valid';
}

this is not a COM specific error, you're trying to create
a new COM object and that fails - rather than return something
that evaluates to false the constructor for the COM object (
or something it is trying to call) is throwing a Exception...
('throwing' of) exceptions (and logically also the 'catching'
of them) are new concepts in PHP5.
try like it this and see whether something more useful error msg
is output:
// this is PHP5 only!
try {
// starting word
$word = new COM("word.application");
echo "Loaded Word, version {$word->Version}\n";
//bring it to front
$word->Visible = 1;

}
catch (com_exception $e) {
echo "something bad happened with COM:", $e->__toString();
}
catch (Exception $e) {

lookup 'try'/'catch'/'throw', 'exception' in the manual (php5 specific
areas).

Updating the array in the shopping basket -- not so easy !!??!!
A shopping basket should be able to add and delete items (done)
You should be able to delete the whole basket (done)
Now I need to be able to update quantity - I've spent at least 5 or 6
hours on this and have gotten nowhere!!! This learning exercise is
getting to be a major time drag.
Any hints would be good.
The code is below:

{
array_splice ($ses_basket_name,
$ses_basket_items, 1);
array_splice ($ses_basket_amount,
$ses_basket_items, 1);
array_splice ($ses_basket_price,
$ses_basket_items, 1);
array_splice ($ses_basket_id,
$ses_basket_items, 1);
$ses_basket_items--;
}
}
if ($action2 == "deleteItem")
{
array_splice ($ses_basket_name, $position, 1);
array_splice ($ses_basket_amount, $position, 1);
array_splice ($ses_basket_price, $position, 1);

Hi there,
I am trying to find a way to count the number of times (if any) words are inside
a string. So I played around with ereg, preg_match_all and so on, but could not
put together a working code.
Can anybody help me on that?

foreach($words as $k => $word) {
$pattern[$k] = "/\b($word)\b/is";
}
}
else {

}
return ereg( $pattern, $str);
}
$words = 'php language';
$str = 'One language which is great is php. PHP works great!';
$num_hits = count_words($str, $word);
echo $num_hits;
I would like to get an case insensitive result. In this example: 3

With regular expressions:

http://dk.php.net/manual/en/function.preg-match.php
I expect You wanna match 555-666-0606? (Angelina Jolies number ;-)
This will match the number from start to end:
^[0-9]{3}-[0-9]{3}-[0-9]{5}$
^ means the start of the string
$ means the end of the string
[0-9] means any number from 0 to 9
{3} means _exactly_ 3 occurences, no more no less (can also be {2,4} if
You world allow from 2 to 4 occurences or {2,} if You want at least 2
digits)
So this line says _start_ with 3 digits followed by a - then 3 digits,
then another - and end with 4 digits
Example:
$number = "555-666-0606";
if(ereg("^[0-9]{3}-[0-9]{3}-[0-9]{4}$", $number)) {
echo "valid phonenumber";

Re: [PHP] mysql + addslashes + stripslashes
Thank you VERY much for you detailed reply.
Especially that part:
"
MySQL "sees" the \' and "knows" that is an embedded apostrophe and saves
your data as "Joe's Grill" down in the guts of MySQL files. Note that
MySQL does *NOT* *NOT* *NOT* store \' as part of the data. The \ is
simply a marker that the MySQL engine "eats" once it understands that it
means: "The following character is DATA, nor part of my SQL begin/end
marker"
"
It was very informative and I almost knew everything except that part that I
quoted you.
After a little thinking I think that it is a good idea to check if
magic_quotes_runtime is set to On for incoming MySQL data and if the data
will be "slashed" :).

Use the following:
/(^@)(@{1})(^@)/
This way you'll be sure the regexp will match only single occurences ot hte
'@' symbol.
Please take in mind that if you have this symbol in the beginning of the
string or at the end - you have to modify this.
