Depending on what you're trying to accomplish, it looks like you're
running into a scope issue. According to the code sample you provided,
the $map object is local to the Loc::outputInfo() method. So, inside
this method, you can access the $map object like
$map->publicMapFunction() provided your Map class defines the
publicMapFunction() method.
If you want to access the $map object outside the outputInfo() method
defined in the Loc class, then you'll need to return the $map object or
provide some other interface to it within the Loc class.
One way to do this would be something like this in the class definition:
class Loc{
public function outputInfo()
{
$map = new Map();
$map->setKey();
return $map;
}
}
Next, in your main page you might do this:
$loc = new Loc();
$myMap = $loc->outputInfo();
Now, if you have the method publicMapFunction() defined in your Map
class, you should be able to access it like this:
$myMap->publicMapFunction();
I'm not sure the my example above is the best way to go about this...but
without knowing exactly what it is you're trying to accomplish I think
it at least should point you in the right direction.
You'll also need to be aware of the difference between how PHP4 and PHP5
handle objects to know whether you're operating on a copy of an object
or a reference to the actual object itself.
Hope that helps!

It's focus is on tracking/archiving issues, so it doesn't have any functionality for asset management.

[PHP] Problem with php.ini
I'm having a problem with php-cli and php_mod reading my php.ini file. I've compiled php from source, during which process I set "--with-config-file=/etc". Once the compile completed, I then copied php.ini-recommened to /etc/php.ini. After restarting Apache, I run phpinfo() and "Configuration File Path" is showing only "/etc", which means it's not find /etc/php.ini. So then I tried the cli and ran phpinfo() from it and same thing. If I run it as "php -c /etc/php.ini", it can find/read it. For what it's worth, this is happening on a Gentoo system, but this shouldn't make too much of a difference since I've compiled PHP from source (v5.0.4), the same source I've used on a couple of other (non-Gentoo) machines. Just in case, here's the configure command I used: './configure' '--with-apxs2=/usr/sbin/apxs2' '--disable-cgi' '--with-config-file-path=/etc' '--with-openssl' '--with-zlib' '-enable-bcmath' '--with-bz2' '--enable-calendar' '--enable-dba' '--with-db4' '--with-inifile' '--with-flatfile' '--enable-dio' '--enable-ftp' '--enable-gmp' '--with-unixODBC' '--with-pgsql' '--with-readline' '--enable-soap' '--enable-sockets' '--enable-wddx' '--with-xsl' '--with-pear' Any ideas?

If I might make some recommendations: unless you're doing something unique as part of the login process, it might be worthwhile looking at the LiveAdmin authentication system. It's available via pear. It allows you to set up authentication containers, which can be an XML file holding your usernames/passwords, or a database like Postgres. It also has containers for permissions. I've tested in a couple of simple apps and it works fairly well. If LiveAdmin doesn't fit your needs, then you might look at Propel (http://propel.phpdb.org/trac/), it's an object persistence layer which provides a couple of benefits: 1) it abstracts your database so you don't have hand-coded SQL scattered throughout your PHP code and you don't have to mess around with the details of connecting to the db; 2) it provides a pretty sweet build tool that takes an SQL schema definition (marked up in XML) for a database and generates not only your SQL to create the tables but also your PHP classes. Then in your application you only need to be concerned with using the generated classes. I realize this isn't what you asked about, but I've used Propel in a couple of small web apps and I've been really happy with it. It cut the number of lines of code in my main application by almost half. Moreover, it helped simplify making changes to the db: if I need to change a field in a table, add/delete a field, or add a whole new table, I simply make the change in my schema file, re-generate my PHP classes, and then use the new classes in my app. I don't have to search through a bunch of code to find all the instances of a particular SQL statement.

[PHP] Best practices for set/get methods
Does anyone have suggestions/ideas about best practices for writing
set/get methods in PHP5? There are two basic ways I've seen this done,
which I've provided examples of below. Method #2 is obviously the easier
way, but that doesn't mean it may be the best way.
I'm curious to read people's responses.
Thanks,
Tim
#1: set/get method for each member attribute
example:
private $foo;
private $bar;
public getFoo()
{
return $this->foo;
}
public setFoo($val)
{
$this->foo = $val;
}
public getBar()
{
return $this->bar;
}
public setBar($val)
{
$this->bar = $val;
}
#2: generalized set/get methods
example:
private $foo;
private $bar;
public getVar($var)
{
return $this->$var;
}
public setVar($var, $val)
{
set $this->$var = $val;
}

Being a newbie to phpunit2, I didn't realize that each test creates a new object; thus, although I had a test to test the passive function, the passive connection to the ftp server got destroyed with the object at the end of that test. So, I had to modify my test code to set the active connection to passive within each test. Tim -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

The short answer is it would download it to the server, not the client on which Firefox is running. But if you were wanting to transfer the file to the client, I'd think you could do something creative like this: 1. Have your script download the file from the remote server. 2. Once the file has been downloaded, display a new page to the browser with a link to the file. 3. Then the user can click the link to retrieve/open the file. Now this may not be the best solution, it just happens to be what I could think of off the top of my head. There may be better ways to accomplish the same thing. Hope that helps!

[PHP] Problem with ftp_get and ftp_put over SSL
I need to transfer files between a server at my company and one of our
vendors. The vendor's running a SecureFTP (FTPS) server. In order to
automate this from our side, I've created a class that wraps the ftp
functions in an object.
When I test my class on a standard FTP server, everything works fine: I
can login, chdir, chmod, get/nb_get, put/nb_put, etc. However, when I
connect to the vendor's server using ftp_ssl_connect (instead of
ftp_connect), everything works fine with the exception of put/nb_put and
get/nb_get. (I'm testing using PHPUnit2, and all my tests pass except
for the get/put tests.)
At first, I thought it may be a firewall issue, but I've checked the
logs on our firewall and nothing is being logged as being blocked at
that level. Also, the firewall rule is written in such a way that it's
allowing all traffic to/from the vendor's server; so it doesn't appear
like it's an issue with the data port not being open. I have verified
that the same commands I'm using in my PHP code work using an FTP
client, and they do. I've used lftp to connect to the vendor's FTPS
server, chmod, chdir, get/put files...everything works fine.
For the put/get commands, when I run my PHPUnit2 tests, I am getting the
following output on the put/nb_put and get/nb_put commands:
Warning: ftp_nb_put(): PORT command successful.
in /home/tboring/scripts/ftp.class.php on line 490
Warning: ftp_put(): PORT command successful.
in /home/tboring/scripts/ftp.class.php on line 587

in /home/tboring/scripts/ftp.class.php on line 399
Warning: ftp_nb_get(): PORT command successful.
in /home/tboring/scripts/ftp.class.php on line 453
Here's the actual code from my test object for all 4 commands:
function testNbput()
{
$this->FTP->nb_put("output.test", "output.test", FTP_ASCII);
echo "\nTest Name: testNbput()\n";
$this->assertEquals(0, $this->FTP->getVar(error_code));
}
function testPut()
{
$this->FTP->put('output.test', 'output.test', FTP_ASCII);
echo "\nTest Name: testPut()\n";
$this->assertEquals(0, $this->FTP->getVar(error_code));
}
function testGet()
{
$this->FTP->get("/tmp/test.txt", "test.txt", FTP_ASCII);
echo "\nTest Name: testGet()\n";
$this->assertEquals(0, $this->FTP->getVar(error_code));
}
function testNbget()
{
$this->FTP->nb_get("/tmp/test.txt", "test.txt", FTP_ASCII);
echo "\nTest Name: testNbget()\n";
$this->assertEquals(0, $this->FTP->getVar(error_code));
}
Here's the corresponding code from my class:

$status = ftp_nb_get($this->conn_id, $local_file, $remote_file,

Wouldn't line evaluate to true in a boolean context? Yeah, the light bulb just turned on for me, too. I'll play around with this and change it to boolean, but it still bothers me. My thinking was that $line was the expression that I wanted the switch construct to evaluate based on each case statement. Thus, if the regex turned out to be true, then it matched that case and would perform whatever code was in that branch. Weirdest of all, however, is that I've gone into the source input file and changed the first "word" in each line from text to a numeric value. And the switch statement works just fine.

I see your point, but the other tests do involve $line. This one that
you reference I'm using for a "special need"--basically so I leave in
the initial column headings from the report, because they would match
several of the tests that would discard those lines.

Thanks for the suggestion, but I'm not sure that does what I'm looking
for. I really think the problem is with my regex, not necessarily with
the way I've constructed my switch statement.
I say this because I have since changed the first word in each line from
something like "AKRN" to a numeric value, and everything works just as I
would expect it to. So it seems as if the "^" might be negating the \W+
part of the regex. Although that shouldn't be happening because "^"
only acts as a negation when it's used inside brackets, at least
according the documentation.
Again, thanks for the suggestion!

It's perfectly legit to use expressions. Now perhaps there is something
wrong with the regex I'm trying to use, but using a regex in and of
itself is legal.

[PHP] Seemingly weird regex problem
Hello! I'm having an odd regex problem. Here's a summary of what I'm
trying to accomplish:
I've got a report file generated from our business management system
(Progress 4GL), one fixed-width record per line. I've got a php script
that reads in the raw file one line at a time, and "strips" out any
"unwanted" lines (repeated column headings, mostly).
I'm stripping out unwanted lines by looking at the beginning of each
line and doing the following:
1. If the line begins with a non-word character (\W+), discard it;
2. If the line begins with the word "Vendor", discard it;
3. If the line begins with "Loc", discard it;
4. If the line begins with a dash, discard it;
5. Else keep the line and write it to an output file.
The way I've implemented this in code is via the code snippet below.
The problem I'm encountering, however, is that any line that begins with
a word, such as "AKRN", is matching rule #1, thus discarding the line.
This is not what I want, but I'm having difficulty spotting my mistake.
To try to help spot the issue, I put in the if(preg_match("/^\W+/",
$line)) logic, and the weird thing is that this logic isn't outputting
the line beginning with things like "AKRN", yet the same line is getting
caught in the switch statement and being discarded.
Any suggestions?
while (!feof($input_handle))
{
$line = fgets($input_handle);
if (preg_match("/^\W+/", $line))
{
echo "$line\n";
}
switch ($line)
{
case ($total_counter <= 5):
fwrite($output_handle, $line);
$counter++;
$total_counter++;
break;
// Rule #1: non-word character
case preg_match("/^\W+/", $line):
array_push($tossed_lines, $line);
echo "Rule #1 violation\n";
$tossed_counter++;
$total_counter++;
break;
// Rule #2: "Vendor" at beginning of line
case preg_match("/^Vendor/i", $line):
array_push($tossed_lines, $line);
echo "Rule #2 violation\n";
$tossed_counter++;
$total_counter++;
break;
// Rule #3: "Loc" at beginning of line
case preg_match("/^Loc/i", $line):
array_push($tossed_lines, $line);
echo "Rule #3 violation\n";
$tossed_counter++;
$total_counter++;
break;
// Rule #4: dash character at beginning of line
case preg_match("/^\-/", $line):
array_push($tossed_lines, $line);
echo "Rule #4 violation\n";
$tossed_counter++;
$total_counter++;
break;
default:
fwrite($output_handle, $line);
$counter++;
$total_counter++;
break;
}
}
