Subject: [PHP] tutorial failure
Readers,
Copy below of message sent 15 August to php install digest list, but to date
not including in mail archive?
The tutorial example:
<html>
<head>
<title>php test
</title
</head>
<body>
<?php
echo '<p>Hi, I am a PHP script</p>';
?>
<p>
this is a test
</p>
</body>
</html>
is saved to the normal user temporary folder as 'test.php' and then copied
to the folder '/var/www/html/' using the root user account. The web browser
is directed to url 'http://localhost.test.php, to show:
Hi, I am a PHP script
'; ?>
this is a test
What is the error please?
Urpmi was used to install so the php version installed is not known.
How to obtain this please
--
Shouldn't that be http://localhost/test.php
Cheers
Arno

Looks like a problem with quotes, I'd say.

Check with php -i from the command line or a script containing
phpinfo(); requested through the browser.

I changed the code as follows:
<html>
<head>
<title>php test
</title>
</head>
<body>
<?php phpinfo ?>
<?php
echo "<p>Hi, I am a PHP script</p>";
?>
<p>
this is a test
</p>
</body>
</html>
The result (http://localhost/test.php):
Hi, I am a PHP script
"; ?>
this is a test
If I use single quotes characters:
Hi, I am a PHP script
'; ?>
this is a test
The phpinfo instruction does not seem to be recognised. What else
should I check?

php is not processing the file. There's a few reasons for this, but the
first thing I would check is the permissions of the file. From the
directory try
$ ls -oa
This should tell you who owns the file and what it's permissions are. You
mentioned that you copied it as root, you could change it's ownership to
www-data.
again from the directory try.
$ chown www-data test.php
then run ls -oa to ensure the change took place.

The file permission was confirmed as root, since it was copied (as
root) from a normal user account directorp 'temporary' to the
directory '/var/www/html'

This fails:
[r...@localhost html]# chown www-data test.php
chown: `www-data': invalid user
So I repeated this with a normal user account and the change in
permission occurs. However, the html file containing the php script
remains unchanged.
The instruction:
...
<?php phpinfo() ?>
...
Does not show the version of php.

Your webserver might not be configured to process php files - which
server are you using?

Apache. Below is an extract of an (to now) unanswered question:
...
<FilesMatch \.php$>
SetHandler application/x-httpd-php
</FilesMatch
Apparently this should be part of the addtype directive. I don't
understand which file I am to edit and add the code shown above.
...
So perhaps apache is not configured but I don't know how to test this.

What are the actual file permissions when you run ls -o?
Do you know if PHP is installed as an apache mod or cgi? Also you might
check what user apache is running as.
possibly...
$ vi /etc/apache2/envvars
and look for something like...
export APACHE_RUN_USER=www-data

No apache2 on my computer, only '/usr/lib/apache' which contains only .so files.

ls -o doesn't give one word answers, so again, what is the output of an
ls -o call in your shell?
I assume that root is the owner of the file here, and the fact that
you're getting some output from it seems to suggest that at least read
permissions are available for group and other, but you should check to
see if the permissions are indeed something like 664 (-rw-rw-r--)
What OS are you using? I'm assuming a Linux distro of some kind here,
but it could also be another Unix variant. Have you tried using the
package manager within the distro (if it is Linux) to install PHP and
Apache together? That makes it a lot easier to get up and running with a
decent configuration, especially if you're unfamiliar with the more
complicated details.
Thanks,
Ash

Some distributions have really screwed up the locations of various
applications. This is compounded by the decision to rename the Apache 2
directories to httpd. Look for /etc/httpd, /home/httpd or
/usr/lib/httpd. If worse comes to worst, try
ps ax | grep httpd
to see if you can find the path from the original start up in the init
process.

In '/etc/httpd/conf' there is an empty directory 'addon-modules'. In
/usr/lib/apache-extramodules there is 'mod_php5.so'.

The command I sent was because - as I said in the original thread
- passing any password directly to the command line is Very Bad[tm].
If you're passing it via exec(), though, and don't want to use an
'expect' shell, passing it directly to -p is at least a bit less
dangerous. Plus, doing so will not leave anything in your
~/.bash_history on the server.
That said, sorry for appearing inattentive, despite this being
directed right at me. I have been out of the office more than in for
the last couple of weeks, while working on a ton of new stuff.
Eventually it will go back to "normal."

Hi list,
I know that some languages such as C++ can overload functions and
methods by declaring the method again with a different number of
arguments, and the compiler internally sorts things out, but I can't
seem to find a similar way to do this with PHP.
Basically, what I've got at the moment is a class method with 2
arguments, and I need to be able to overload the method with 3
arguments. The following which would work in other languages doesn't
seem to bring any joy in PHP:
class foo
{
public function bar($arg1, $arg2)
{
// do something with $arg1 & $arg2
}
public function bar($arg1, $arg2, $arg3)
{
// do something different with all 3 args
}
}
Is there any feasible way of doing this? The method names really need to
remain the same as they exist as part of a framework, but the arguments
really server quite different purposes between the two methods, so
there's no nice way of just merging the two functions without breaking
the naming conventions, etc used.
Thanks,
Ash

Would something like this work for you?
class foo
{
public function bar($arg1, $arg2, $arg3=null)
{
if (isset($arg3)){
{
return $this->_bar3($arg1, $arg2, $arg3);
} else {
return $this->_bar2($arg1, $arg2);
}
}
also you may want to look into the func_get_args function.
Chris.

Thanks to everyone, I decided to modify the existing original method and
use func_get_args() to grab the arguments passed to it. It's not
perfect, because I lose out on the automatic value assignment that I
would have with a regular method (i.e. function foo($bar, $fubar=0) etc)
but it will do at a pinch.
It's a shame this sort of overloading isn't supported, as it could be
quite a useful feature, but it's not a complete show-stopper.
Thanks,
Ash

Hi Ashley,
Sorry for a slow reply, but I've found a free second and I'd like to toss
out the scheme I've used most often.
If args 1 and 2 are consistent in terms of type and usage across the two
methods, I simply add arg3 with a default to null and conditionally call a
private method that performs the special operation (documentation and
primary entry point remain in one place. Essentially, I just add a guard
clause to the original function. The
class foo
{
public function bar($arg1, $arg2, $arg3 = null)
{
if (!is_null($arg3)) return _specialbar($arg1, $arg2, $arg3);
// do something with $arg1 & $arg2
}
public function _specialbar($arg1, $arg2, $arg3)
{
// do something different with all 3 args
}
}
If, however, the functions differ significantly in terms of signature, I
tend to write a wrapper function that chooses the appropriate internal call
(e.g., newbar()), but this doesn't play too nicely with documentation within
the PHP ecosystem (although within other language systems such as Java, C#,
and Erlang, it's really quite nice and elegant), so I tend to structure my
code to make use of option one when possible.

Hello list :)
Just a short question which I know it should be easy, but I'm no expert yet
in regular expressions.
I've got a nice little XML string, which is something like this but can be
changed:
<?xml version="1.0" encoding="utf-8"?>
<boolean xmlns="http://tempuri.org/";>false</boolean>
The boolean value can be true or false, so what I want to do, is filter it.
I've done it this way, but I know it can be improved (just because I love
clean coding and also because I want to master regular expressions xD):
$result = preg_match('/true/',$curl_response);
if ($result == 0) $result = preg_match('/false/',$curl_response);
I've also tried something like:
$result = preg_replace('/^(true)|^(false)/','',$curl_response); // if not
true OR not false => replace with empty
and also '/^true|^false/' which doesn't seem to work.
Any ideas to filter this kind of string in just one expression?
Thanks in advance :)

Camilo,
What exactly are you trying to achieve? Meaning:
if (true)
do this;
if (false)
do that;
However, here's a link that I used long back to help me with some RegEx :

As far as I can tell, are you just trying to grab the content from the
<boolean> tag text node? If it's limited to this basic example, there's
likely not much of a need to use dedicated DOM functions, but consider
using them if you need to work on more complex documents.
If you are just trying to determine if the value is indeed true or false
and nothing else, then a regex could be overkill here. As you only need
to check two values, consider:
if(strpos($xml, 'true') || strpos($xml, 'false'))
{
// text node content is OK
}
else
{
// bad, bad input, go sit in the corner
}

Ash

Indeed Ashley, I'm trying to get the TRUE / FALSE value from the boolean
tag.
After reading again, you're absolutely right: strpos does just what I need
it to do: a simple search for a true or false. (Or null, in which case
strpos will be FALSE anyway).
Thanks for your suggestion, I was doing an overkill here.
@Shreyas: thanks for the link! It is very helpful to speed up the testing a
bit!
Greetings!

I am really in need of some help here! Whenever I try to use fopen,

get the following errors:
Warning: file_get_contents(): SSL: connection timeout
Warning: file_get_contents(): Failed to enable crypto

The SSL connection timeout message occurs immediately. The server is not
blocking outbound communications as a tcpdump on the server that php is
trying to connect to shows connection activity, however, the apache and php
logs on this server do not show any entries at all when php tries to connect
to it.
On the server with php installed on it, openssl appears to be installed
correctly.

I'm trying to write a VERY simple script that does nothing but store all the
submitted GET and POST vars in a string and echo it out.
$response = print_r($_REQUEST, true);
echo $response;
The problem is it only shows GET vars. I've tried $POST instead of $_REQUEST
and it always gives an empty array. I've got it on two different servers, and
we have three guys trying various methods of submitting forms to it, trying to
eliminate all potential problems, like the possibility that the request might
not actually have any POST vars. I think we've safely eliminated these
possibilities.
Can anyone see a reason why the above should not see POST vars? Is there some
security setting I don't know about?
