Yep. same result. Possibly have another httpd.conf file that Apache is reading? Possibly. I used the package installer from Marc liyannage's web site which seems to have done something odd to the httpd.conf file but I don't know enough unix yet to fix it without possibly screwing up. there are the following config files in the /private/etc/httpd directory: httpd.conf httpd.conf.applesaved httpd.conf.bak httpd.conf.default httpd.conf.entropy-backup.1059884513 httpd.conf.entropy-temp In addition to these, there is another config file named "httpd.conf.php" in the "/usr/local/php/" directory Which one Apache is using is a mystery to me.

Re: [PHP] Scripts not running on OS X 10.3
Odd. To be sure it's using the conf file you want, have you tried starting Apache with the command.? /path/to/httpd -f /path/to/httpd.conf I tried your suggestion but the system won't let me modify it even with su permissions. I'm too tired and frustrated to continue tonight. Clearly, the installer must have messed something important up so I'm just going to reinstall Panther tomorrow (have to partition my drive anyway so what the heck) Thanks for all your help.

[PHP] Looping through results of pg_meta_data()
I'm trying to build an html table using the results from pg_meta_data()
but none of the access functions seem to work. I am getting results but
just can't seem to do anything with them.
Here's what I'm using to verify that results are being returned:
$connstring = "dbname=pub_status user=postgres host=localhost
port=5432";
$db = pg_connect($connstring);
$meta = pg_meta_data($db, 'table_definitions');
echo '';
var_dump($meta);
echo '';
Which yeilds:
array(2) {
["field_id"]=>
array(5) {
["num"]=>
int(1)
["type"]=>
string(4) "int8"
["len"]=>
int(8)
["not null"]=>
bool(true)
["has default"]=>
bool(true)
}
["field_name"]=>
array(5) {
["num"]=>
int(2)
["type"]=>
string(4) "text"
["len"]=>
int(-1)
["not null"]=>
bool(true)
["has default"]=>
bool(false)
}
}
But none of these seem to do anything:
$row_count = pg_num_rows($meta);
echo $row_count;
-> result a blank web page
$row = pg_fetch_row($meta, 0);
echo $row;
-> result a blank web page
$row = pg_fetch_array($meta, 0);
echo $row;
-> result a blank web page
$row = pg_fetch_object($meta, 0);
echo $row;
-> result a blank web page
What am I doing wrong?
Thanks for any help,
Ken

[PHP] Form containing 2 menus not returning anything
I created an html form comprised of two menus but when the action method for the form calls my "handler.php" script, neither of the menu variables contain anything. Could someone point out what I'm doing wrong?

Re: [PHP] Form containing 2 menus not returning anything
Thanks John, that did the trick.
I'm curious though, the PHP book I'm reading (PHP and PostgeSQL,
Advanced web programming) specifically states that it's not necessary
to grab form variables in this way, claiming PHP extracts all form
variables behind the scenes for you. Was my original syntax something
that used to be supported but has since been deprecated?

[PHP] can't open a file
Hi
I'm trying to create/open a file for write in a subfolder of the
folder that contains my PHP script but am having no luck.
Here's the relevant code
$oldPath=
'/test/old_page_'.$oldRecord['page_number'].'.txt';
$oldHand= fopen($oldPath, "w+");
if ($oldHand === true)
fwrite($oldHand, $oldData);
else
die('Failed to open file "'.$oldPath.'" for writing!');
fclose($oldHand);
The permissions for the "test" folder is set to me in a WebServer
subfolder on Mac OS X. Do I need to set permissons to something else
to get this to work? If so, what permissions should I use?

[PHP] No is_date() function?
Hi
I wrote a serialization function to turn arbitrary PHP variables into
Macintosh plist compatible XML but see that there is no "is_date"
tester as there is for bool, object, array etc. Is there a relatively
simple (and robust) way to detect if a variable is a date? For example:
$person = array('name'=>'bob', 'sex'=>'male', 'date_of_birth'=>
$someDateHere);

Re: [PHP] No is_date() function?
Thanks Lars
I saw that one already but unfortunately, it doesn't help as it
requires 3 inputs . What I'm shooting for is an 'is_date' function
that returns true or false with no prior knowledge of what a variable
might contain.

[PHP] Bizarre array create error
Hi
I'm trying to assign two fields of an object returned from a MySQL
query and have stumbled upon the most bizarre PHP bug where I can't
create two arrays in succession.
Here's the MySQL query with two dummy fields to be filled in later
select *, 0 as dummy_1, 0 as dummy_2 from table
Here's how I'm grabbing the query results
$result = array();
while ($row = mysql_fetch_object($query_result))
{
$result[] = $row;
}
Once that's done, I try to set two of the rows to arrays like this
$result-> dummy_1= array(1, 2, 3, 4);
$result-> dummy_2= array('a', 'b', 'c', 'd');
If I comment out either of the above lines, the script works but with
both uncommented, it seems to drop dead. It doesn't even return an
error.
I rebooted my system thinking PHP might have gotten into a funky
state but that didn't work. I retyped the function from scratch but
it still breaks on these two lines. I did a "show invisibles" and
"show spaces" in BBEdit to see if there was a hidden character, none
found. I did a hex dump to see if there was a hidden character that
BBEdit was missing, nope. And I haven't upgraded PHP in a year so
it's not a question of an unstable update.
I've been doing assignments like the above for 3 years and never had
a problem and in fact the exact same function works perfectly in
another script.This one has me utterly stumped.
Anyone have an idea what might be causing this? Or something else I
could try to glean more info about the failure?
Thanks in advance

Is this all of your code?
No. Here's the full function:
function get_document_type_for_pub($inPubID)
{
$query = "select doc_type.*, 0 as rect, 0 as usable_rect, 0 as
usable_width, 0 as usable_height, 0 as column_width, 0 as

$result->column_width+= 0.0;
// calculate derived values
$result->usable_width = $result->page_width - $result->left_margin -
$result->right_margin;
$result->usable_height = $result->page_height - $result->top_margin
- $result->bottom_margin;
$result->column_width = ($result->usable_width - $result-
>gutter_width * ($result->column_count - 1)) / $result->column_count;
/*--*/
/* Next two lines are where the problem starts */
/* If I comment either of them out the script runs */
/* but with both uncommented, it dies
/*--*/
// create the rect and usable rect records
$result->rect = array(0, 0, $result->page_width, $result-
>page_height);
$result->usable_rect = array($result->left_margin, $result-
>top_margin, $result->usable_width, $result->usable_height);
// create the offset and box width arrays
$offsets= array();
$widths = array();
$left = $result->left_margin;
$width = $result->column_width;
$inc= $result->column_width +
$result->gutter_width;
for ($i = 0; $i < $result->column_count; $i++)
{
$offsets[] = $left;
$widths[] = array('column_width'=> $i + 1,
'point_width'=> $width);
$left += $inc;
$width += $inc;
}
$result->column_offsets = $offsets;
$result->box_widths = $widths;
return $result;
}
Do you have some sort of output display for your results?
No. Once it hits the "create the rect and usable rect records"
assignments, it's like the script didn't even get called. Nothing
returns.
Does PHP generally return errors to the browser?
I'm not using a browser, I'm making direct calls to the script from a
Cocoa class on a Mac
Does that script run on the same machine?
Yes. I'm doing all development on my MacBook and the scripts all live
in my local web folder.
If it's on another machine is that machine running the same
version? I ran this on a server with Apache 2.2.4, PHP 5.2.3 and
mySQL 5.0.18. Have you referenced that other script to make sure
that it *is* exactly the same?
I cut and pasted it from its original home to a new script and it
stopped working.
Thanks for replying Tom. I'll check out the php.ini settings tomorrow

$result is an array and you are treating it like an object...
While this is supposed to work, I think, it's pretty confusing to this
naive reader...
$result['dummy_1'] = array(1, 2, 3, 4);
would make more sense...
That doesn't work. (I tried already) You have to use the "->" syntax
for objects returned by an MySQL query.
And you do realize that your actual objects are ELEMENTS of the array
$result, not $result itself...
So maybe you want something more like:
$row1 = $result[0];
$row1->dummy_1 = array(1, 2, 3, 4);
Yeah. My original post was incorrect. I'm actually doing something
more like your above suggestion
$result[0]->dummy_1 = array(1, 2, 3, 4);
I posted the complete function at 1:04 a.m. July 30 if you want to
take a look
That said, you're altering an Object that MySQL returned, and I've got
NO IDEA what kind of an object that is, or what you're allowed to cram
into its variables...
The weird thing is, I've been doing this type of assignment for a
couple of years, haven't upgraded my copy PHP for a year, but all of
a sudden it breaks. Very puzzling...

[PHP] Unexpected values in PHP array
Hi
I think this is probably just a misunderstanding on my part, but I'm
creating associative arrays with string keys from MySQL query results
and when I put a value in the array, I get the expected key
association along with an index key that has a different value.
For example: If I have a table "Foo," do a select, perform coersions
on the results, and place the coerced value in an array with a key, a
second uncoerced value is also placed in the array with an index key.
I know all associative arrays have both key and index accessors, but
I would think that the values should be the same.

Re: [PHP] Unexpected values in an associative array[Solved]
Turns out that objects returned from SQL queries contain two parts
for every field, one with a string key and one with an index key.
Adding an "is_numeric" test on the keys allows you to filter out the
numeric keys if you want to. For example:
foreach ($row as $key => $value)
{
if (!is_numeric($key))
{
/* do stuff here */
}
}

What is $coersions or $inQuery['coersions']? Maybe a var_dump or a
print_r on that for the list?
For the above record, $coersions is an associative array of the form
array('task_id'=> 'integer', 'container_id'=> 'integer',
'name'=>'hex_decode');
I found that I was doing a lot of coersions with results of SQL
queries to turn them into real integers, floats or decode from base64/
hex before I could use them so rolling all that ugly stuff into the
query makes it so users of the function don't have to do coersions
any more. There may be a better way to perform coersions from string
types returned by PDO queries and their real types but I'm a PDO noob
so don't know if one.
What is $value and what is this supposed to do:
case'integer':
$value
+= 0;
break;
case'float':
$value
+= 0.0;
If $value is a string, you should quote your 0 and 0.0. What add 0
or 0.0 to an int or float respectively?
The point of these is to convert the strings to ints, floats, decode
them etc...
What's the extra "[]" about in $rows[$groupKey][] = $fields;
Maybe that's where your duplicates are coming from although I don't
see duplicates in your output.
Another thing I found the need for was to group rows in a select
result by specific keys. For example say a query gets all ads in a
publication, and you want to physically group them by page. That's
what that group function does.

[PHP] Does PDO prevent class functions from calling other class functions?
Hi
I've been writing PHP classes for around two years now but all of a
sudden, the things I used to do don't work any more. I have a class
that implements utility functions for database calls using PDO and am
finding that I can't call one utility function from within another.
If each function is called by itself from a script, they work
perfectly. This is really basic stuff so I'm very puzzled why it
isn't working. The only difference between these new classes and my
old classes is the use of PDO. Could PDO be causing all these headaches?
Anyone see where I'm screwing up?
Thanks in advance

well, youre not throwing an exception here in your code, your doing
something called
swallowing the exception. which is typically not a good practice.
catch (PDOException $e)
{
print "Error!: " . $e->getMessage() . "";
die();
}
and you could show us the output from
$e->getMessage()
thats where the script is blowing up. calling die() after that
will obviously stop processing
so you have no hope of recovering gracefully.
There is no error. The browser calls the script and paints a blank
screen. If I do a "view source" same deal, nothing.
Here's the MySQLDatabase "query_database' function that passes the
actual call to PDO
function query_database($inQuery)
{
$query = $inQuery;
$coersions = null;
$object_key = null;
$group_by_key = null;
if (is_array($inQuery))
{
$query = $inQuery['query'];
$coersions = $inQuery['coersions'];
$object_key = $inQuery['object_key'];
$group_by_key = $inQuery['group_by_key'];
}
try
{
// determine query type
if (strpos($query, 'insert') === false)
{
$rows = array();
$rowCounter = 0;
foreach ($this->db->query($query, PDO::FETCH_NAMED) as
$row)
{
$rowFields = array();
$recordKey = $rowCounter;
foreach ($row as $key => $value)
{
// remember this key if it matches the
user specified object key
if (($object_key != null) && ($key ==
$object_key))
$recordKey =
$value;
// perform user specified coersions
if ($coersions != null)
$value =
$this->coerce_value($value, $coersions[$key]);
$rowFields[$key]
= $value;
}
// perform grouping if requested
if ($group_by_key == null)
$rows[$recordKey] =
$rowFields;
else
{
$groupKey =
$rowFields[$group_by_key];
if ($rows[$groupKey] == null)
$rows[$groupKey]=
array();
$rows[$groupKey][] =
$rowFields;
}
$rowCounter++;
}
return $rows;
}
else
{
// return last insert ID
return ($this->db->lastInsertId() + 0);
}
}
catch (PDOException $error)
{
print "Error!: " . $error->getMessage() . "";
//die();
}
}
And here's a modified version of the "directory_path_for_pub_id" with
a try/catch
function directory_path_for_pub_id($inPubID, $inDirType)
{
echo 'entered: directory_path_for_pub_id';
try
{
$site = $this->site_for_pub_id($inPubID);
echo 'site: '.$site.'';
}
// Tried both of these. Result: blank window/blank "view source'
catch ($e)
catch (Exception $e)

[PHP] PDO::ATTR_TIMEOUT script specific?
Hi I have a script that needs to get ad information from two different sources, a primary and fallback. The primary source is a high traffic (and poorly designed/unpartitioned MSSQL database) with millions of records that gets locked up when 'certain folks' (ie executives) perform large queries. What I'd like to be able to do is set a timeout for a query to this database of 5 to 10 seconds and branch to the fallback database if the timeout expires. I can't just use the fallback as my primary as it doesn't always have the most up to date info. It's really only for placeholder queries until the primary frees up. So the question is, does setting PDO::ATTR_TIMEOUT affect all scripts or just the one that set the variable?

You could define a generic action function

Actually, this might be better as it makes no assumptions about the
function's argument list.
function action()
{
$func = func_get_arg(0);
$expr = func_get_args();
$expr = array_slice($expr, 1);
$expr = implode(', ', $expr);
$expr = $func.'('.$expr.');';
return eval($expr);
}
You lose the ability to pass by reference but that might not be
important for your script.
and use it on any function you want to use as an action function
function printColor($color) {
echo 'color: '.$color.'';
}
function printArea($width, $height) {
echo 'area: '.($width * $height).'';
}
action('printColor', 'blue');
action('printArea', 3, 5);
You could then pass in any function that is visible to the action
function. You lose some efficiency but get your action function
Then again, you could also just prepend action functions with
'action_'

[PHP] PDO lastInsertID always returns zero for MySQL tables
Hi
In the past, I always used mysql_insert_id() and never had a problem,
but now that I'm using PDO, I'm finding that it always returns zero.
The tables are identical between the two methods but where
mysql_insert_id works $pdo_connection->lastInsertID() doesn't.
The PDO documentation states that you need to feed lastInsertID
something called a "sequence object." I'd never heard of those before
so after some reading here http://www.mckoi.com/database/
SQLSyntax.html#7 it looks like you have to create these yourself .
But MySQL tables already seem to have a built-in sequence (as
evidenced by the auto_increment flag when creating tables) and
creating another one for a given table could lead to id collisions.
So basically, the question is: Is it possible to get valid
"lastInsertIds: using PDO with a MySQL database that mirrors the
behavior of mysql_insert_id?
Thanks for any help

[PHP] No luck creating dynamic images
I've been trying for most of the day to generate a simple dynamic image in my php script without any success. It seems obvious that something isn't right with my php environment as even the simplest images (like a rectangle) only yield the broken link icon.

[PHP] Using system resident fonts with "image_xxx" routines?
Is it possible to use fonts on a system with php's image routines?

[PHP] Using DOM object, how?
I was looking at the PHP DOM documentation here "http://www.php.net/
manual/en/ref.dom.php" (which is rather sparse in the way of
examples) and can't even get to square one.
Here's an example from the php site:
');
echo $doc->saveXML();
$doc = new DOMDocument();
$doc->loadXML('');
echo $doc->saveXML();
?>
Problem is, it chokes on the first line with the error:
Fatal error: Undefined class name 'domdocument' in /folder/
dom_test.php on line 1
Anyone know how to use this thing?

Re: [PHP] Re: Using DOM object, how?
The first line of that page - " The DOM extension is the replacement for the DOM XML extension from PHP 4." makes me suspect that it may be a PHP 5 feature, and sure enough, a look in the changelog confirms this. php.net/ChangeLog-5.php#5.0.0b1 So if you are using php < 5.0, that would explain your error.

Re: [PHP] Re: Using DOM object, how?
I would be extremely careful with this.. because sadly PHP's XML

Will work.
Thanks for the heads up. Looks like if you define the tag like
$script= $dom->createElement('script',''); <-- empty string
It tacks on an end tag.
I personally would love to see a function where I could set it to
use the long
form. and when importing if it's in long form.. set that long from
flag on
automatically .. this would have saved me _hours_ of debugging work.
are you trying to just generate the entire html page using only the
XML
DOM? .. or are you doing this in conjunction with another language
such as
XSL?
So far, just playing. But ultimately I'd like to generate the whole
page using dom calls. It seems much cleaner for what I'm doing than
creating a whole bunch of large functions that do nothing more than
echo prestyled html.

Re: [PHP] Re: Using DOM object, how?
Rats. Looks like you can't encapsulate DOM objects in your own
classes. I tried this and the browser 'view source' shows a
completely empty document.
createScriptElement('howdy.js');
class MyDom
{
function MyDom()
{
$dom = new DOMDocument('1.0', 'iso-8859-1');
return $this;
}
function createScriptElement($inScriptPath)
{
$script= $this->dom->createElement('script','');
$script->setAttribute('language', 'javascript');
$script->setAttribute('src', 'howdy.js');
$this->dom->appendChild($script);
echo $this->dom->saveXML();
}
}
?>
If the element adding code is in the same function as the dom create,
it works
createElement('script','');
$script->setAttribute('language', 'javascript');
$script->setAttribute('src', 'howdy.js');
$dom->appendChild($script);
echo $dom->saveXML();
return $this;
}
}
?>
Also if the DOM object is declared outside the class, and class
functions access it as a global it works
createScriptElement('howdy.js');
class MyDom
{
function MyDom()
{
return $this;
}
function createScriptElement($inScriptPath)
{
global $dom;
$script= $dom->createElement('script','');
$script->setAttribute('language', 'javascript');
$script->setAttribute('src', $inScriptPath);
$dom->appendChild($script);
echo $dom->saveXML();
}
}
?>
Would be nice if you could encapsulate it though...
You can probably add an empty text node to the script tag, or a
text node consisting of a single space, or something like that, to
make it use the long form.

Shouldn't this be

'iso-8859-1');
?
That didn't work either. tried a few other things as well and it
looks like PHP forces you to define DOM documents in one hideous
monolithic code block without any of the encapsulation benefits
classes provide.
Not sure if this intentional due to security issues or if it's a bug.
Anyone think of a reason why it would be necessary to prohibit DOM
object embedding in a class?

[PHP] Strange array access problem
I'm having a major problem with what seems, on it's face, to be a
really basic array function.
What happens is on the browser end, I've written some javascript code
that packages up javascript variables in native PHP format and sends
the packed variables to a PHP script on the server via a POST and
XMLHTTP. On the server end, the PHP script grabs the packed variables
out of the $_POST, strips slashes and uses the "unserialize" command.
Here's the function that gets the post data
$unpacked_data= GetDataFromPOST();
And here's a var_dump of $unpacked_data as it appears in the browser
array(1) { ["handler"]=> array(1) { ["0"]=> string(9)
"databases" } }
I'm able to get the "handler with no problem like so:
$parts= $unpacked_data['handler'];
Which yields the following var_dump
array(1) { ["0"]=> string(9) "databases" }
Here's where the problem starts. I've had no luck whatsoever trying
to get items of $parts. I've tried all of the following and each of
them return NULL
$part_1 = $parts[0];
$part_1 = $parts['0'];
$part_1 = $parts["0"];
$part_1 = $parts[48]; <- ASCII character for zero
In desperation, I also tried this
foreach($parts as $key => $value)
{
var_dump($key);
// => string(1) "0"
var_dump($value);
// => string(9) "databases"
$parts_1 = $parts[$key];
// => NULL;
}
But no luck
I also checked the type and size of the key like so
foreach($parts as $key => $value)
{
echo gettype($key);
// => string
echo sizeof($key);
// => 1
}
Anyone have any insights as to what the heck is going on here? This
should be a piece of cake but It's stopped me cold for a full day and
a half
