Framework = Overhead (when compared to vanilla PHP). Period. I'm not
saying it's overhead that will cripple your application, or that
frameworks should be avoided... quite the contrary, in fact. I have
recently fallen in love with CodeIgniter myself--I'm just saying that
one should be at least respectfully aware of the overhead that comes
hand-in-hand with a(ny) framework, and weigh those against what you
feel is acceptable for your purpose.
  
And I'm saying that using vanilla PHP sometimes (I'd say more often than 
not - especially with a group of developers of varying skill and 
experience) leads to sloppy programming, bad architecture and monolithic 
libraries, which in turn can lead to more overhead than simply starting 
with a framework. Not that a framework will save you from bad code - but 
it should point you in the right direction and make it obvious how you 
*should* do things.

[PHP] Evaluating math without eval()

[Jason Norwood-Young]

Hi all

First post to this list! I'm trying to figure out how to evaluate a
string with a mathematical expression and get a result, but without
using eval() as I'm accepting user input into the string. I don't just
want addition, subtraction, multiplication and division - I'd like to
take advantage of other functions like ceil, floor etc. 

So the string "18-10" should give me 8, "ceil(1/2)*10" should be 10 (if
my maths is correct) and the string "18-10;\r\nunlink('/var/www/*');"
should not execute.

Any ideas?

Thanks!
Jason

Thanks Richard

Unfortunately it's not that simple. The equation sits in a DB and can be
anything - eg. ((([valuation]/[purchaseprice])/100)*100)/[numyears]
would be a typical field. [valuation], [purchaseprice] and [numyears]
gets replaced by relevant fields from user-entered data. But the system
is expandable which means I don't know what the equations, data or
fields are going to be beforehand. 

I'm working on some kinda preg_replace function to sanitize the data at
the moment and then run an eval - arg I hate regexp! Ideally eval would
have some kind of sandboxing option, or you could limit the functions
available in an eval.

In reply to my own question, I came up with the following function based
on a comment on php.net
(http://www.php.net/manual/en/function.eval.php#71045). I had a look at
the array returned by get_defined_functions() and the maths functions
seem mostly to be grouped (with the exception of the random number
stuff). It works on my installation but there's nothing in the
documentation about get_defined_functions() returning in a particular
order - it would be safer to list each math function but I'm lazy.

protected function safe_eval($s) {
$funcs=get_defined_functions();
$funcs=$funcs["internal"];
$funcs=array_slice($funcs,array_search("abs",
$funcs),array_search("rad2deg",$funcs)-array_search("abs",$funcs));
$sfuncs="(".implode(")(",$funcs).")";
$s=preg_replace('`([^+\-*=/\(\)\d\^<>&|\.'.$sfuncs.']*)`','',$s);
if (empty($s)) {
return 0;
} else {
try {
eval("\$s=$s;");
return $s;
} catch(Exception $e) {
return 0;
}
}
}

Hi Rodrigo

I recently did a little app that maintained persistent connections to a
XMPP server - a similar solution should apply to your problem.

I built a memory-resident app in the middle that received a unique ID
from my PHP page (you could use session_id for instance), assigned that
ID to a connection and created a permanent connection. It also queued
incoming messages so that when the PHP script connected again, it could
send through the queued messages, so that the end-user didn't miss
anything.

Initially I tried using PHP-cli for the memory-resident app but
eventually settled on Twistd Python because it was better at running
resident and handling multiple connections from different users without
blocking anything. On the front-end I used PHP and Ajax to give a
feeling of a "live" connection.

Good idea Ray. I'm thinking that it might be safer to exec a separate
app - preferably sandboxed. That way it could still be PHP (or anything
else really) but without the headache of compromising the main
application.

Might be obvious but you are doing "mysql_query($sql);", right?

Also add a try catch around your mysql_query to check what's happening.

A quick way would be to try and make an image with the GD library.
Something like:
if (imagecreatefromstring($img)) {
header("Content-type:image/png");

If you take this approach, just make sure you build a proper queuing
system or mark the mails you're processing as being processed in the DB.
Otherwise you could end up with a situation where the system takes
longer than 5 minutes to process the mails (it shouldn't, but you never
know - maybe there's a rogue process or the mail queue is backed up or
something) and then the PHP script starts at the beginning of those 50
mails again. It's an obvious error, but I've done it in an app where I
thought "There's no way the process won't finish before the next cron
job starts", and then it happened and I ended up sending a couple
thousand SMS's out twice at cost to my client. Oops.

Hi revDAVE

You'll simplify your life dramatically by using one database and one
connection per application. If you're not going to do that, you can make
sure the table is there in PHP with something like:

function check_table_exists($tablename) {
$sqlresult=mysql_query("SHOW TABLES LIKE $tablename");
if (mysql_num_rows($sqlresult)==1) {
return true;
}
return false;
}

And I disagree. I'm just putting the finishing touches on a large
multi-user asset management system, built without a framework (apart
from my own collection of objects I wrote and reuse to accelerate
development). 40 000 lines of code and my previous version is currently
being used by banks and such. We'll move them over to the new one soon.
It's taken about 3 months full-time work.

But, while I think there's nothing wrong with building from scratch as
long as you architect carefully before you start, I think that there's
also nothing wrong with frameworks. As long as you choose the one that
is best going to suit your needs from the start, it can make life
significantly easier. If you're building a web site for a client, you'd
be insane to not seriously consider a CMS like Drupal or even WordPress
(don't laugh - it's got quite a competent plug-in system and if you're
in a rush you can bang something good out the door in a day.) I'm
currently building a project based on CodeIgniter, and apart from quite
a rigid structure, you do most of the stuff yourself anyhow. I dumped
the built-in DB object for one of my own and now development is
cruising. 

So, my philosophy is one of choosing the tool that best suits your
needs, your client's needs and your project's needs, rather than using
or not using frameworks based on some preconception.

Actually it's quite easy. I've got a similar object to the one you guys
described (can't really share it - I'm on salary so technically it
belongs to my boss.) Anyhow when I do my table layout, if there's a
look-up, I name the field "lookuptable_id" in the DB. In my object, it
looks for any field ending in "_id" (or whatever you specify to the
object - "_id" is just the default) and it creates a drop-down of the
options. 

The object also takes an array of ignore_fields, hidden_fields (good for
ID's on updates), friendlynames (you don't always want to use the
fieldname in the database, but anyhow the object replaces underscores
and capitalises), and a bunch of other customising array properties with
useful defaults. It also detects whether this is an insert or update and
knows how to route the action, and has support for file uploads (and
customises the enctype of the form for that).

So basically you can have a very nice form, customised, with one or two
lines of code to draw the form, as long as you design your object and DB
well.

Here's how I do it. I make a file with the output of ffmpeg and then
just parse the file for duration. After looking at a lot of options,
this proved to be the easiest and most reliable. Here's my code that
also finds the mid-time and grabs an image of the middle frame for a
thumbnail:

//tmpname is the temp name of the video
//First we get some info about the video with ffmpeg
$cmd="/usr/local/bin/ffmpeg -i $tmpname 2> $tmpname.info";
system($cmd,$ok);
if (!$ok) {
  return false;
}
$ffinfo=file_get_contents($tmpname.".info");
$ffinfo=substr($ffinfo,strpos($ffinfo,"Duration:")+10,strlen($ffinfo));
//Now that we got the duration we parse the string so that we get hours,
mins and seconds
$ffinfo=substr($ffinfo,0,strpos($ffinfo,"."));
$runningtimeparts=explode(":",$ffinfo);
foreach($runningtimeparts as $rt) {
   $newparts[]=floor((($rt/60)*0.5)*60);
}
//Get the mid point
$midtime=($newparts[0]*3600)+($newparts[1]*60)+$newparts[2];
$midtimestr=implode(":",$newparts);
//$jpegname is the name of where you want to save the thumbnail
$cmd="/usr/local/bin/ffmpeg -i $tmpname -ss $midtimestr -y -r 1 -vframes
1 -f mjpeg $jpegname";
system($cmd);

For URLs you can do a tinyurl-type solution. Quite easy in fact. Just
save the long url in a db table, along with a short url (say a
4-character random string). Then do a page that looks up the short url
and redirects to a long url (eg. http://www.myblog.com/r?id=Sve7
redirects to http://www.veryverylongurl.com/blahblahblah.php). For extra
points you can make the short url look like http://tiny.myblog.com/Sve7.
Just remember to put the short url creation in a loop that checks that
the short url isn't in the DB already and repeat if it is.

For long words, you could explode the words into an array, and if the
words are longer than a certain length, insert a hyphen and space for
your wrap. Then just implode back into your string and bob's your uncle.

Anyhow that's how I'd do it.

Dur, just realised it's only *display* that you're worried about so
shortening the url isn't really an issue. It's too early in the
morning...

Yeah you might want to check out HTML Entities
(http://www.php.net/manual/en/function.htmlentities.php) - great help in
encoding. Then set a doc type too.

Hi John

You might consider CodeIgniter - it's a very nice, simple to use
framework with a pretty good DB abstraction layer built in.

This is usually a malformed XML document - I had the problem recently
when fetching an XML document that wasn't complete (no ). Check
what you're *actually* getting with something like:

} catch(SoapFault $exception) {
$request_xml = $client->__getLastRequestHeaders() .
$client->__getLastRequest();
$response_xml = $client->__getLastResponseHeaders() .
$client->__getLastResponse();
print "Response:".$response_xml;
print "Request:".$request_xml;
print $exception;
}

Dude! You forgot the most important bit:
inc/config.inc:
$dbusername="root";
$dbpassword="r00t"; //By combining letters and numbers, this password
becomes unhackable

It's important to also set your server root password the same as your DB
password so that when you hand passwords out to your outsourced
developers, secretaries, tea ladies and janitors they can have full
access to the system and don't waste your time setting up permissions.

Your myCalTime isn't an array of arrays of arrays, like you're
suggesting in the foreach.

$calArray=array();
for($x=0;$xarray('NULL','linked-day
".strtolower($myCalTime['reason'][$x])."','".$myCalTime['day'][$x]."'),";
}

How do you plan to have users enter the info? Through the Flash player,
through some kinda Ajax form, through a form in a frame or just a static
form? 

Also, would the tags be predefined by you (eg. genres like the ID3 tag
genres) or would people be able to add their own tags?

The way I'd do it would be to let the users enter the info through an
Ajax form below the video, with suggestions popping up as they type.
Then save it in a separate table (I assume all your vids are in their
own table) with a link table between the vids table and the tags table
(M2M relationship). This means that if the tag is already in there and
linked to one vid, you don't replicate it for a second vid. It's also
very easy to do lookups of similar items. I'd also add a weighting to
the tags in the links table, maybe with the more people that add a
specific tag, the more weight that tag gets. 

Also check out http://www.music-map.com/ as an example of showing
similar music - you might even be able to plug into this data.

In that case, I suggest the following solution:
1. Download the unternet into your puter
2. Open the file called mysql.com
3. Read and learn
4. Open the file called php.net
5. Read and learn
6. Rinse and repeat

In all seriousness, this is a nice, simple project to learn on. You want
to look at different types of relationships in Sql (one-to-one,
one-to-many and many-to-many) and learn a bit about basic DB
architecture; make some tables and play with getting data in and out
(get PHPMyAdmin to help you out); maybe use a nice simple framework like
CodeIgniter to get you kick-started on the PHP.

What I love about CodeIgniter is that, while some frameworks obfuscate
my thinking, CodeIgniter clarifies my thoughts, structure and overall
architecture. MVC programming is no longer some mysterious theoretical
entity - it just makes sense with CodeIgniter. Plus it doesn't tell you
how to do something - it just gives you the structure for you to decide
and do whatever you want. And it's so light I'd barely call it a
framework - more like a kick-start. I could wax lyrical about this all
day. Maybe I should write an ode...

I didn't find CodeIgniter difficult to learn - a few hours of reading
and a few hours of playing. I was comfortable within one evening.

The license for CodeIgniter is pretty simple. Since it's unlikely you'll
ever need to mess with the framework itself - you can override any
object - I don't see it's modification clause really coming into play.
