PHP is a server side language. If you want to have php as an
executable on the client, you could look at www.roadsend.com for the
compiler. Otherwise, you could create a dll on windows for for

though the manual is perfectly clear that this should be expected, i was a
bit surprised that the result of the following is 42
?php
function foo($a) {
$a = 42;
unset($a);
$a = 'meaning';

foo($a);

normally i would expect unset() to free some memory. but in this example it
doesn't and has a different behavior: it releases foo's reference to the
global $a, allowing the next line to define a local $a.
i think i'd have preferred compile error.

Well, you unset the reference and then you assigned 'meaning' to a local
function variable $a. Why would you get a compile error?

You made a mistake in your code:

In response to Sebastiano:
There would be not much point in using something like PHP if it ignored the if

What effectively happens in a PHP source file is that all the bits outside of
the ?php ? tags are treated like an echo statement (except that it handles
quotes and stuff nicely)
Your original code:
?php if (the_title('','',FALSE) != 'Home') { ?
h2 class=entry-header?php the_title(); ?/h2
?php } ?
can be read like:
?php
if (the_title('','',FALSE) != 'Home') {
echo 'h2 class=entry-header';
the_title();
echo '/h2';
}

You might even find a small (but probably really, really, really small)
performance improvement if you wrote it that way, especially if it was in some
kind of loop.
Note that I prefer to keep HTML separate from PHP as much as possible because it

[PHP] Structure of PHP files
Hi, It isn't really a programming question, but rather a structural. Let's suppose I have a PHP page, which is built by other PHP files' includes. Which is the better approach: in a switch-like statement I include the required PHP files, which contain all the functions, and the HTML code to provide the functionality, or create a base PHP file which contains all the funcionality, and the PHP files only contain calls for these functions, and the HTML code? I think the previous method gives more control and it is more repairable, but the later method gives more modularity. With your experiences, what method gives the better overall usability? Thanks, SanTa

Thanks, SanTa As far as i experienced, the second method brings problems about the REQUIRE. If you do put classes and functions directly in that base PHP file, it will looks fat , and you need a lot of copy/pastes. If you just put a lot of requires in that base PHP file, you may pay attention about the PATH. Usage of __FILE__ or __autoload may bring confusions. Hoping for the coming of the concept of PACKAGE.

How can this kind of url be parsed to the file index.php and the pagetitle be parsed as params? Why the web server not go straight into path index.php/ and look for the file named pagetitle ? This type of thing is common for sites using the MVC or Model-View-Controller paradigm. The index.php file is what's called a front controller. A front controller is usually the entrance to all the other pages of a site. URLs like this often take advantage of an Apache feature called mod_rewrite, which tells Apache how to handle URLs which look like this. Or by the pathinfo mechanism, which I believe is also supported by other Web servers, and can work just as well, if it satisfies your requirements, without all the complications of mod_rewrite.

Re: [PHP] Structure of PHP files
When I first started programming in PHP I used the second method you mentioned. I had a single file I called utils.php and it contained all the functions I could possibly need throughout my site. Unfortunately, this file grew to be over 10,000 lines and most of the time I only needed a couple of functions for each script I loaded. I have now abandoned that method and use a more modular approach. I have a lib folder that contains much smaller and specialized scripts (mainly classes). Now I only include what I need.

Re: [PHP] EXEC and SYSTEM delay
Well if the server your running on is linux based (and I haven't tried
this) you could try adding a nohup and background the task for example
rather than doing:
system('updatedb');
try
system('nohup updatedb ');
It should background the task and let it continue running even when the
php script finishes it's execution. Like I said I haven't tested it. As
a side note I used 'updatedb' in the example because it was the longest
running task I could think of off the top of my head and requires root
priveledges... You really shouldn't run your scripts as root. *A public
server announcement*

I'm experimenting problems with a call that I made to exec or system. The
problem is that the script await for the function finish and that take's a lot

I need a way to use those functions in order to continue without await for it.

Re: [PHP] Re: unsetting a referenced parameter in a function
I think he is confusing the unset semantic.
Unset just destroy a variable, but not the content of it.
Take a look at the output of this simple script:
function avoid_global_scope()
{
$a = 'foo';
var_dump( get_defined_vars() );
$b = $a;
var_dump( get_defined_vars() );
unset( $a );
var_dump( get_defined_vars() );
unset( $b );
}
avoid_global_scope();
This is the output in my apache2 / php 5.2.6... but yours MUST be the same
array(1) {
[a]= string(3) foo
}
array(2) {
[a]= string(3) foo
[b]= string(3) foo
}
array(1) {
[b]= string(3) foo
}
Note in the second array both variables was converted to references.
But in the third b is just a common variable.
This behaviour is cause by how PHP handles the references?
1) $a = 'foo';
Here we have an string 'foo' and a variable a which points to the string.
2) $b = $a;
Now we have anothe variable b which refers to _contents_ of variable a
Variable a is converted to a reference to it contents
3) unset( $a );
When a is destroyed only b refers to 'foo', PHP handles b as a common
var
3) unset( $b );
When b is destroyed PHP notes that no one is referencing 'foo'... so, it's
removed too.
Remember... unset destroy variables, not it's content.
class Foo
{
public static $last;
function __construct()
{
self::$last = $this;
}
}
$a = new Foo;
$a = null;
unset( $a );
var_dump( Foo::$last instanceof Foo ); # bool(true)

With a compile cache it's quite likely that over time you'll have the 150k loaded into memory anyways. It's just going to take longer for it to be loaded since the compile cache has to encounter it first. Once encountered it's still occupying the same memory. Additionally, the operating system does an excellent job of swapping memory not being accessed regularly (if it needs memory).

[Fwd: Re: [PHP] Undefined Index ...confusion]
Sorry, list, I did a reply instead of a reply-to-all. This is what I
sent to Miller, Terion

Thanks for the link Kyle!! Great thing there...(seriously I didn't know...I
learn something everyday)
Anyways the link to my script is: http://pastebin.ca/1504393
Your email client is annoying, it doesn't quote. Haha.
Anyway, so, you're loading up that array with arrays of arrays, here:
1.
$position = 1;
2.
3.
while ($row = mysql_fetch_array
http://www.php.net/mysql_fetch_array($result))
4.
{
5.
$_SESSION['fullRestaurantList'][$position] = $row;
6.
$position++;
7.
}
8.
9.
$_SESSION['totalNumberOfRestaurants'] = $position;
So, if you get 7 rows. Your array will have:
Array = (Row 1 Data)
Array = (Row 2 Data)
.. etc
You do not have ['fullRestaurantList']['ID']. In the page you're
referencing you use something like
$_SESSION['fullRestaurantList'][$i]['SomeValue']. I assume $i is the
Position in the array, so you likely want to use
$_SESSION['fullRestaurantList'][$i]['ID'] to get the ID field from that row.
If you need a quick dump to better understand what data you have in your
session, try making a page called session_dump.php in the same directory
with this source:
pre? print_r($_SESSION) ?/pre
That will give you a good idea of what your session array looks like,
and you should see clearly that ['fullRestaurantList']['ID'] does not exist.
Hope this helps!

normally i would expect unset() to free some memory. but in this
example it doesn't and has a different behavior: it releases foo's
reference to the global $a, allowing the next line to define a local $a.
i think i'd have preferred compile error.
Well, you unset the reference and then you assigned 'meaning' to a
local function variable $a. Why would you get a compile error?
when you state it in those terms (which are clearly correct) i wouldn't.
but if the way i think is unset() destroys the specified variables
(as the manual puts it) then i expect that the specified variable
would be destroyed, not the reference.
so, as i said, i was a bit surprised when the variable wasn't destroyed.
once i understood what was happening, i thought it a bit confusing to
have such scope-dependent differences in behavior of a language element.
It might be easier to understand if you don't use the same var names:
function foo($arg) {
$arg = 42;
unset($arg);
$arg = 'meaning';
}
$a = 0;
foo($a);
print($a\n);
-Shawn
--
Another way to see it (from Shawn's example): the is an address of
(reference to) a variable, so function foo($arg) creates a local variable
$arg pointing to a global variable called $a. Changing the value of local
$arg updates the global $a. The unset($arg) removes the local $arg but has
no effect on global $a. The next line $arg = 'meaning' creates a new local
variable called $arg which has no connection whatsoever with the $arg that
was unset - it could just as well have been called $xyz.
As Shawn pointed out there's no problem here with scope, you were just
confusing yourself by using the same variable name in the function, but it's
a separate local variable regardless of what name you give it.
A slight variation of your example:
?php
function foo() {
global $a;
$a = 42;
unset($a);
$a = 'meaning';
}
$a = 0;
foo($a);
print($a\n);
?
You get exactly the same result as your example, for the same reason, the
only difference is that you obviously can't change the local variable name
in the function.
A final variation (to drive the point home):
function foo($arg) {
global $a;
$a = 42;== at this point $arg = 42
unset($a);
$a = 'meaning'; == $arg is still 42
$a = $arg; == $a now points to same address $arg is pointing to
$a = 'of life'; == $arg now = 'of life'
}
$a = 0;
foo($a);
print($a\n); == prints 'of life'
Here in function foo() local $arg and local $a are both pointing to the
global $a, and changing either of them changes the other (and changes the
global variable). After unset($a) only local $arg is pointing to global $a.
After $a = $arg both local variables are again pointing to global $a, and
local $a value has therefor obviously changed from 'meaning' to 42. Then
after $a = 'of life' both local variables and the global $a is changed to
'of life'. Local $a and global $a have the same names but are different
variables. Also, the local $a after unset($a) happens to have the same name
as the $a before unset($a) but it's a different variable, it could just as
easily been called $b after unset($a).
A final point: the global $a; in the function doesn't mean it's THE global
$a, it just means it's a local variable called $a pointing to (referencing)
a global variable with the same name. In PHP it has to be the same name
because that's the way the global statement works, but it can sometimes
create the impression that it's the same variable.
Hope I haven't made that as clear as mud.

[PHP] Renaming all variables in a repository
Hey all, we've got a repository here at work, with something like 55,000 files in it. For the last few years, we've been naming $variables_like_this and functions_the_same($way_too). And now we've decided to switch to camelCasing everything and I've been tasked with somehow determining if it's possible to automate this process. Usually, I'd just use the IDE refactoring functionality, but doing it on a per-method/per-function and a per-variable basis would take weeks, if not longer, not to mention driving everyone insane. I've tried with regular expressions, but I can't make them smart enough to distinguish between builtins and userland code. I've looked at the tokenizer and it seems to be the right way forward, but that's also a huge project to get that to work. I was wondering if anyone had had any experience doing this and could either point me in the right direction or just down and out tell me how to do it.

Is there a way I can take the output of phpinfo() from both servers and do a compare that will tell me what the differences are?

You can use this simplest function to translate a string to camelCase.
The process could be...
1) parse by PHP
2) translate tokens to camelCase
3) writte the file with changes
You can easily parse a php file using http://php.net/token_get_all

Hi Eddie,
That's quite the task :).
You're going to need to scan the source to generate a list of every
variable and function name using the tokenizer. Fortunately, this is
easy - with the caveat that if you do this anywhere in your source:
$a = $this-{$constructed . '_name'}();
you will have to handle these manually.
Basically, run token_get_all() on the source, scanning for T_VARIABLE,
and record every T_VARIABLE in an array. Then, scan for:
1) T_FUNCTION T_WHITESPACE* T_STRING
2) T_OBJECT_OPERATOR T_WHITESPACE* T_STRING
?php
$replace = array();
foreach (new RegexIterator(new RecursiveIteratorIterator(new
RecursiveDirectoryIterator('/path/to/src')), '/\.php$/',
RegexIterator::MATCH, RegexIterator::USE_KEY) as $path = $file) {
$source = file_get_contents($path);
$checkForID = false;
$var = false;
$last = '';
foreach (token_get_all($source) as $token) {
if (!is_array($token)) continue;
if ($checkForID) {
if ($token[0] == T_WHITESPACE) {
$last .= $token[1];
continue;
}
if ($token[0] != T_STRING) {
$checkForID = false;
$last = '';
continue;
}
$token[1] = $last . $token[1];
} elseif ($token[0] == T_FUNCTION || $token[0] == T_OBJECT_OPERATOR) {
$checkForID = true;
$last = $token[1];
continue;
} elseif ($token[0] == T_STRING) {
if (function_exists($token[1])) {
continue; // skip internal functions
}
if (strtolower($token[1]) != $token[1]) {

Re: [PHP] Compare PHP settings of two different servers
David, Robert, Thank you for replying. Just diff the HTML. Unfortunately it is not that easy. Even if the same PHP modules are present, if they are written into the page in a different place, they show up as differences. The same goes for all the HTML tags and everything else, so what I end up with is a ton of text, no more streamlined or easy to analyze than the original output from phpinfo(). I'm hoping there's a way more targeted way of discerning what settings one server may have that another server might not. -- Dave M G -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

Run 'diff -iw' on the sorted files. Add additional flags to diff as needed. If you need more than that, you will probably have to write your own utility to handle it. You should also get copies of httpd.conf and php.ini from each server and compare them. They will affect how some of those modules behave.

RE: [PHP] Compare PHP settings of two different servers
From: Dave M G I'm currently having a problem with PHP writing text to a PNG image on one server. I have various web sites hosted on various servers, and on most of them, the script that generates the image is writing text properly. I have ensured that the same fonts are available on all the servers. Another thought comes to mind. What text encoding are you using and what are the locale settings on those servers?

I was wondering if anyone had had any experience doing this and could

how to do it.
Hi Eddie,
That's quite the task :).
You're going to need to scan the source to generate a list of every
variable and function name using the tokenizer. Fortunately, this is
easy - with the caveat that if you do this anywhere in your source:
$a = $this-{$constructed . '_name'}();
you will have to handle these manually.
Basically, run token_get_all() on the source, scanning for T_VARIABLE,
and record every T_VARIABLE in an array. Then, scan for:
1) T_FUNCTION T_WHITESPACE* T_STRING
2) T_OBJECT_OPERATOR T_WHITESPACE* T_STRING
?php
$replace = array();
foreach (new RegexIterator(new RecursiveIteratorIterator(new
RecursiveDirectoryIterator('/path/to/src')), '/\.php$/',
RegexIterator::MATCH, RegexIterator::USE_KEY) as $path = $file) {
$source = file_get_contents($path);
$checkForID = false;
$var = false;
$last = '';
foreach (token_get_all($source) as $token) {
if (!is_array($token)) continue;
if ($checkForID) {
if ($token[0] == T_WHITESPACE) {
$last .= $token[1];
continue;
}
if ($token[0] != T_STRING) {
$checkForID = false;
$last = '';
continue;
}
$token[1] = $last . $token[1];
} elseif ($token[0] == T_FUNCTION || $token[0] == T_OBJECT_OPERATOR) {
$checkForID = true;
$last = $token[1];
continue;
} elseif ($token[0] == T_STRING) {
if (function_exists($token[1])) {
continue; // skip internal functions
}
if (strtolower($token[1]) != $token[1]) {
continue; // assuming you UPPER-CASE constants, this skips them
}
} elseif ($token[0] != T_VARIABLE) {
continue;
}
// we get to here if we've found one to process
$new = explode('_', $token[1]);

Thanks so much, man. I'm using most of your methodology, although
there were definitely some hiccups along the way, but it seems to make
a map of what to replace and what to replace with so far, although the
code is far from pretty. I'll be sure to send it to the list when it's
done.

Re: [PHP] Converting SQL Dialects
You might even be able to convert EMPTY(X) to COALESCE(X, '') = ''. MySQL seems to be pretty forgiving with its implicit type-casting. Hmm... The new system I've written properly handles the datatype and EMPTY... So this would be a hack to much around with regexs to replace EMPTY in customer built selects. Now I fiddled around with this on 5.1.33-community on Windows and I get the following odd results... select coalesce(0,)=0,coalesce(,)=0,coalesce(0,)=0,coalesce(,)=0; returns 1, 1, 1, 1 but... select coalesce(0,)=,coalesce(,)=,coalesce(0,)=,coalesce(,)=; returns 0, 1, 0, 1 Which implies that in certain circumstances = 0 but 0 != (unless I'm missing something).

Either way it looks like I can use coalesce(X,)=0 which should be useful! Matt That is interesting. The whole purpose of the COALESCE function in SQL is to substitute a non-null value for a null value. Since there aren't any nulls in either of your statements, you are effectively running these: select 0=0, ''=0, 0=0, ''=0 select 0='', ''='', 0='', ''='' COALESCE(X, '') = 0 is probably the better option though, since the result of COALESE should be implicitly cast to the datatype of X before performing the equality comparison. In MySQL, casting an empty string to an integer would result in the value 0 while casting to a date would produce the date value equivalent to the integer 0. The benefit of COALESCE is that it should be standard SQL. I know it works on MySQL and SQL Server, and I think it works on Oracle and others as well. You may take a performance hit for using COALESCE in conditions like that since it usually means the condition can't use an index, but considering you're moving from using similar logic in FoxPro that may not matter for you.

Anyways the link to my script is: http://pastebin.ca/1504393
Your email client is annoying, it doesn't quote. Haha.
Anyway, so, you're loading up that array with arrays of arrays, here:
1.
$position = 1;
2.
3.
while ($row = mysql_fetch_array
http://www.php.net/mysql_fetch_arrayhttp://www.php.net/mysql_fetch_array($result))
4.
{
5.
$_SESSION['fullRestaurantList'][$position] = $row;
6.
$position++;
7.
}
8.
9.
$_SESSION['totalNumberOfRestaurants'] = $position;
So, if you get 7 rows. Your array will have:
Array = (Row 1 Data)
Array = (Row 2 Data)
.. etc
You do not have ['fullRestaurantList']['ID']. In the page you're
referencing you use something like
$_SESSION['fullRestaurantList'][$i]['SomeValue']. I assume $i is the
Position in the array, so you likely want to use
$_SESSION['fullRestaurantList'][$i]['ID'] to get the ID field from that row.
If you need a quick dump to better understand what data you have in your
session, try making a page called session_dump.php in the same directory
with this source:
pre? print_r($_SESSION) ?/pre
That will give you a good idea of what your session array looks like,
and you should see clearly that ['fullRestaurantList']['ID'] does not exist.
Hope this helps!

[PHP] Question on code profiling
I'm trying to profile a site on our development server to see why it takes around 4 seconds to generate a pretty basic page. I installed xdebug to use for the profiling, and now I'm really confused. Even though it takes around 4 seconds to build the entire page, the profile says that the total processing time is around 416ms. I thought it might be calls to require_once/include/include_once. While they are significant (around 46%), it says they only account for 193ms. What could account for that much difference between what xdebug calculates versus the total elapsed time?

Re: [PHP] Question on code profiling
Nope. Basically it connects to a database to load an ACL (which at [...] I thought xdebug was supposed to be a pretty good profiler. If it calculating the time correctly, where are the other ~3.6 seconds going? One night I saw a script wait indefinitely for a response from a tanked database, and PHP's max_execution_time trigger never fired to end the script, even though it was set to a pretty low value. Some poking around led me to http://us.php.net/manual/en/function.set-time-limit.php where I found this odd note: Any time spent on activity that happens outside the execution of the script such as system calls using system(), stream operations, database queries, etc. is not included when determining the maximum time that the script has been running. This is not true on Windows where the measured time is real. The last sentence was particularly confusing because I was running on Windows. At any rate, if xdebug is using the same mechanism used by set_time_limit() and max_execution_time, perhaps that could explain your discrepancy? I second Jonathan's suggestion; I would try calling microtime() before and after your database query, and before and after anything else that isn't strictly execution of the script.

Re: [PHP] Mediawiki's url confusion

While I was installing mediawiki, i did nothing with the file httpd.conf, no changes made on mod_rewrite. The mediawiki install script cannot do nothing to httpd.conf i think. So i'm confused about how the url-rewriting mechanism is activited. This can also be accomplished by Apache's lookback feature. If it's turned on on the server, Apache will look back through the URL until it finds something which is a file, and then consider the remainder of the URL parameters, which it provides to the file. Thus, http://example.com/index.php/pepperoni/pizza will end up at http://example.com/index.php with pepperoni/pizza as parameter, assuming that pepperoni and pizza are not files/directories and index.php is not a directory. The lookback feature can be turned on in the Apache configuration file, which, on a public server, you have no access to. Paul -- Paul M.

Re: [PHP] Re: A form and an array
In php.ini turn the display_errors to on.
If any error,warn or notice shown,copy them and paste here.
So you can tell us what doesn't work.
good luck~

Re: [PHP] Mediawiki's url confusion
I think PATHINFO is probably what i'm looking for. Paul mentioned the lookback feature, i think that is or about the same thing. MediaWiki-1.15.1 use the pattern of url for common pages like this : some_path_to_mediawiki/index.php/something , and the 'something' supports even non-english characters. Maybe this kind of usage to transfer params can improve the SEO ? I was trapped in the question how can the MediaWiki scripts affect the apache's behaviour, then finally found out it just takes advantage of the existing FEATURE when i tried this kind of url to my script which var_dump the $_SERVER and saw the pathinfo ... Thank you all, best wishes ~ Deng 2009/7/23 Ford, Mike m.f...@leedsmet.ac.uk -Original Message- From: Paul M Foster [mailto:pa...@quillandmouse.com] Sent: 23 July 2009 06:13 On Thu, Jul 23, 2009 at 11:57:51AM +0800, ?? wrote: But I cannot help myself with the url pattern : /somepath_to_mediawiki/index.php/pagetitle. How can this kind of url be parsed to the file index.php and the pagetitle be parsed as params? Why the web server not go straight into path index.php/ and look for the file named pagetitle ? This type of thing is common for sites using the MVC or Model-View-Controller paradigm. The index.php file is what's called a front controller. A front controller is usually the entrance to all the other pages of a site. URLs like this often take advantage of an Apache feature called mod_rewrite, which tells Apache how to handle URLs which look like this. Or by the pathinfo mechanism, which I believe is also supported by other Web servers, and can work just as well, if it satisfies your requirements, without all the complications of mod_rewrite.
