The function stack is printed by debug_backtrace(), isn't it? Supported
by PHP since 4.3.0.

If your read my original posting then you would know, that I expicitly
asked for a non-eval solution. Because we solved it with an eval too.
But I would like to watch for a solution without an eval.

true enough, thats why I suggested the OP might want to reevaluate the whole
idea ... personally I don't see much point in a create() function for new objects.
but anyway :-)

objects are slower than functions.
functions are slower than straight up code.
OO in php5 is a lot better than in php4 also in terms of speed.
php5.1 brings a new execution model in the zend engine (IIRC),
regardless the change I refer to gives a not to small speed boost
for OO stuff.
bottom line - its fast enough, and if you need more speed maybe you
need to write a custom extension :-)

That is just what I wana hear.
Actually, in most web applications, the real bottle-neck of performance
is the Database, but not the PHP scripts-of coz, I don't take obvious
mistakes.
So I don't wana write my application without OOP or functions, just for
this bit performance improvement. I need a well maintianed product.

my thought exactly - script speed is not that important;
maintainability, readability and extensibility are paramount unless you like
long hours and big headaches ;-)

I can't agree any more!
Maintainability is the most important, and if there is no readability or
extensibility, there is no maintainability.
So I recongnize what I should do now.

Hi
I would like to convert from one naming convention within a sql statement to
another.
I have the following,
<code>
$str = "insert into userComment (userID, userName, userSurname) values (0,
'Leon', 'Vismer')";
$match = array(
"/([a-z]+)(ID)/",
"/([a-z]+)([A-Z])/"
);
$replace = array(
"\$1_id",
"\$1_\$2"
);
$nstr = preg_replace($match, $replace, $str);
echo $nstr ."\n";
</code>
the above gets me to
insert into user_Comment (user_id, user_Name, user_Surname) values (0, 'Leon',
'Vismer')
however I want to get to
insert into user_comment (user_id, user_name, user_surname) values (0, 'Leon',
'Vismer')
Some help from the regex experts ;-)
Many thanks

Just a quick note; why dont' you search on "user" since it's the constant and replace 'user[A-Z]' with 'user_[a-z]' or in the case of userID 'user[A-Z]{2}'

This is part of my problem user will not always be constant, I basically want
to be able to change between two naming conventions.
Example:
userID becomes user_id
clientID becomes client_id
tableName becomes table_name
anotherTableName becomes another_table_name
etc.

Hi Robin
Many thanks for this,
how would one extend this to support the following:
$str = "insert into userComment (userID, userName, userSurname) values (0,
'Leon', 'mcDonald')";
one does not want
$str = "insert into user_comment (user_id, user_name, user_surname) values (0,
'Leon', 'mc_donald')";
unfortunately lookbehind assertions does not support non-fixed length chars so
/(?<=(?<!')[a-z])([A-Z]+)/e will work for 'mDonald' but the following will not
work.
/(?<=(?<!')([a-z]+))([A-Z]+)/e
Any ideas?
Many thanks

Hi!
I have one checkbox. I checkbox is checked I show additional fields
(just set visiblity to true). But some of that fields are required only
if this checkbox is checked. Is this possible with quick_form. I try
myself with grouping but without any luck.

the state of the checkbox. Makes sense?

If I understand your idea the code would look like this
$form->addElement('text', 'taxNumber', 'Tax:');
$checkbox = &HTML_QuickForm::createElement('checkbox', 'isCompany','');
if ($checkbox->getChecked()) {
$form->addRule('taxNumber','required','Tax number is required');
}
if ($form->validate()) {
....
Btw yes it must be checked when user submit this. But If it's possible
client option on rule, would be better.

That would be the idea, yes. It was some time since worked with
Quick_Form, so there might be a specific order you need to perform the
adding of the rule in relation to the validate() method call on the
$form object.

I am not sure about this, is there even client-side validation support
in Quick_Form? Haven't really looked into this. I would suggest writing
a manual javascript evaluation for the specific fields that should be
visible when the checkbox is checked, or to have a postback between. The
JavaScript option sounds most tempting, since it makes it a bit more
user-friendly. That way you can use the JavaScript alert() function to
present the fields that have erroneous information as well as altering
styles in the fields in question to perhaps have a red border to
indicate errors.

Without a code example, I am forced to give a generic answer. Here's one
way to do it:
<?
$selection=5; // User previously picked option 5
$ddselection[$selection]=' selected ';
?>
<select name="D1">
<option<? echo $ddselection[1]; ?> value="1">Option 1</option>
<option<? echo $ddselection[2]; ?> value="2">Option 2</option>
<option<? echo $ddselection[3]; ?> value="3">Option 3</option>
<option<? echo $ddselection[4]; ?> value="4">Option 4</option>
<option<? echo $ddselection[5]; ?> value="5">Option 5</option>
<option<? echo $ddselection[6]; ?> value="6">Option 6</option>
<option<? echo $ddselection[7]; ?> value="7">Option 7</option>
<option<? echo $ddselection[8]; ?> value="8">Option 8</option>

The easiest way to do this is to keep all the select option items in an
associative array and iterating this with foreach or for to output the
<option/> elements. That way you can directly check the value of each
option to detect which was selected.
MailerCode(tm):
<?php
$select = array('a' => 'Item 1', 'b' => 'Item 2', 'c' => 'Item 3');
?>
<form ...>
<select name="MySelect" id="MySelect">
<?php
foreach ($select as $value => $text) {
$selected = '';
if (!empty($_POST['MySelect']) && $_POST['MySelect'] == $value) {
$selected = ' selected';
}
printf('<option value="%s"%s>%s</option>%s', $value, $selected,
$text, "\r\n");
}
?>
</select>
</form>

is not in first column of the line (when I cut n paste the code into an

You also didn't close the PHP block after END_FORM;
Then you need to open a PHP block at about line 635 before the if

Hi.
I'd like to find or write a script that I can run every so often (hourly
for example) from cron that will check my pop3 mailboxes for any emails
with ****SPAM**** in the subject line and either delete them or forward
them to another email address. The best way would be to bundle all the
emails together and forward these as attachments to another email
address that I would use as spam.
I have found the documentation on using php for pop3 a little confusing
as it seems to be geared towards imap. I know it can be used for pop3
it's just the documentation on this seems to be a little scarce. Can
anyone help me find an already written script or give me some ideas on
how I can write my own.
Many thanks,
IG

While that sounds like a good idea there are two things that hamper the
effectiveness of this is a total solution;
1. The logs have many queries from other applications that *don't count*
in this scenario.
2. Not all of the queries may run frequently enough to appear in the
logs.

I guess I misunderstood your goal. You said before that you needed to LOCATE the
queries, which the above will do (if certain assumptions are true). What exactly
are you wanting to accomplish? Are you trying to write a script that will extract
the entire query from a set of PHP files?
If so, and given this:
$variableName = "INSERT INTO bar (foo) ";
$variableName .= "VALUES ('".$foo."') ";
Would you expect:
INSERT INTO bar (foo) VALUES ('')
or something else?
At any rate, if you are trying to automatically extract entire queries, I'd say
that's pretty tricky, unless your code uses very strict idioms for defining queries
that it doesn't stray from. For example, if the code always do this:
$query = "select .....";
$query .= "from .....";
$query .= "where ....";
That's one thing, but if it sometimes does this:
$query = "select ....".
"from .....".
"where .....";
Then that's something entirely different.
Assuming the first, you could perhaps use a two-pass approach where you first go
through a file and find the beginning of a query assignment (using a regex like the
one above), then extract the variable name and line number. Then on a second pass
start from each line number you saved and process line number + N lines (where N is
the largest number of lines the code normally takes to define a query, arbitrarily
chosen) and look for lines where the variable name is followed by an assignment
operator (= or .=). Then use a regex on those lines to extract everything between
quotes (hopefully just double quotes, unless the code tends to switch between double
and single). But then you run into problems when your N is too large and the end of
one chunk overlaps into the beginning of the next. I would imagine something like
this would take a lot of time to get right, and even then only be an 80% solution,
if that.
It seems to get this 100% right you'd have to have a full-fledged PHP parser, which
means hacking the parser that PHP itself uses. Even hacking the PHP parser probably
wouldn't get you a 100% solution because the compile stage won't be enough....there
is going to be code that may or may not be evaluated at runtime and I think it would
be impossible to know without actually running it.
So...if you absolutely have to have this done programmatically (as opposed to just
locating the beginning of the queries and manually extracting them) then I would say
good luck to you. :) Hopefully someone else has some ideas...

Especially as \u is likely to be a special sequence in the Unicode-enabled

Is it a bug that ($var == 0) is always true for any string $var?
[/snip]
You are comparing a string to an integer.
attached mail follows:
No, Christopher, that is not a bug. As long as the var is empty, and if
you try to compare with 0, or false, it will report true in the
comparison because the variable does not contain anything, which will
mean false for a boolean and 0 for a variable. If you are attempting to
discover if a string contains data, use empty() instead. You can also
check if the string is null or actual zero (0).

Torgny

Right. This is clearly documented at http://www.php.net/operators.comparison

Christopher J. Bottaro wrote:

For any string? How about the string 5? :-)
PHP tries to help you out, but there's not much it can do when you ask
it to compare a string like 'foo' to an integer. It scans your string
from left to right and uses the leading numbers to create the integer.
For example, 53chris is 53, but chris53 is 0 (no leading numbers).
Hope that helps.

But the var isn't empty.
$a[] = 'blah';
$a[] = 'blah';
$a['assoc'] = 'array';
foreach ($a as $k => $v)
if ($k == 'assoc')
# do something
The 'if' statement is incorrectly executing when $k is 0. I find it strange
that 0 == any string. The way I see it, 0 is false. false == 'a string'
should not be true.
Thanks for the reply,

Oh, I see...it converts the string into number, not the other way around.

I changed this sample to the following;

print_r($a);
foreach ($a as $k => $v){
if ($k == 'assoc'){

Andf the output was;
Array
(
[0] => blah
[1] => blah
[assoc] => array
)
blah
array
Does it begin to make more sense now?

You might try "===" instead of "==" to get type checking as well...

Hello All,
What are best practices for deleting records in a DB. We need the
ability to restore the records.
Two obvious choices are:
1) Flag them deleted or undeleted
2) Move the deleted records to seperate table for deleted records.
We have a complex schema. However the the records that need to be
deleted and restored reside in 2 different tables (Table1 and Table2).
Table2 uses the primary key of the Table1 as the Foriegn key. The
Primary key for Table1 is auto-generated. This make the restoring with
the same primary key impossible, if we move deleted data to a
different table. However if we just flag the record as deleted the
restoring is quite easy.
Any thoughts/ideas ?

Hi,
Can PHP connect to a remote Oracle db?
Because all oracle connecting functions only require 'user' and 'pass'

Yeah, you can connect to Oracle remotely. The standard PHP functions should do it probably, but I've done it using ADODB.
I don't know if this is the same on a *nix box, but I was running PHP on a Windows box and needed special Oracle stuff installed on my machine to connect to the Oracle DB. There's a file..something like "tsnames.ora" that has the database information. Sort of like their version of ODBC. You give it an aliased name, then give it all the server info, then when you connect to Oracle, you give it the name that's entered into "tsnames.ora" (or whatever the file is) and the username/password combo.
Maybe that'll give you a nudge in the right direction.
Good luck! Let us know what you find!

xfedex, yes you can connect to a remote Oracle DB, I'm doing for an app
I'm trying to write. You have to configure php with the oracle version
you have, more than likely with the --with-oci8=/u1/oracle/product/10g
line, of course your oracle location will differ.
I chose to use the PEAR::DB to do my oracle stuff instead of the oci calls.
This made it simple, and easy to read for me as I'm still learning.
The code looks cleaner also.

Hello!
I'm using PHP and Smarty to try to build an array of arrays using the
results from nested queries. I am just learning about nested arrays,
and I'm not sure what I'm doing wrong.
I am hoping someone can give me a hint as to what I am doing wrong. I
looked on php.net, but still couldn't figure it out.
If I remove the PHP foreach loop, it works fine, except, of course, no
sub projects show up. The error must be in there, but I'm just not
seeing it.
I get the following error with the code below:
