Well, you may reply, equally condescendingly, that you will need
that to have cited references, as it's simply incorrect.  According to
the latest survey conducted by w3techs.com[1], though SharePoint is
used on sites with some of the highest traffic on the Internet, its
saturation point is just 0.3%.

According to the survey, the five CMS platforms ahead of it in
popularity, in order, are (and quite expectedly): WordPress, Joomla!,
Drupal, vBulletin, and Blogger.  And of those five, one is a service
(blogger.com), and the rest are all open-source CMS systems ---
written in PHP.

[PHP] While on the topic of PHP Web Site Stats - SharePoint...

2011-09-19 Thread George Langley

Hi all. Had a meeting today where I was rather condescendingly told 
that most CMS web sites use SharePoint. Last I checked:



Wordpress, Joomla! and Drupal (PHP, PHP and oh look, PHP) kind of had the CMS 
market wrapped up, with numerous other systems fighting for the remains. In 
fact, I don't see SharePoint even listed at the above link.

Any stats on (warning - buzzwords ahead) "External-facing" web sites 
using SharePoint?

At $$$ for the required server software, compared to <$ for just about 
anything PHP-based, can only imagine companies using SharePoint must have their 
IT department in charge of the web site. Am sure it's fine as an internal 
project management tool, but am very concerned when other developers tell me to 
run away from anyone who chooses to use SharePoint on anything public.
Thanks.

The while loop will continue executing until its condition is false. As
you've got a boolean true as the condition, it will never end.

Why do you want the process to continue indefinitely? Is it for a daemon
of some kind?

No, it isn't a daemon, but it does something and wait the end of

RE: [PHP] Why [?php while (true) { sleep(5); } ?] dies on CLI?

2009-06-11 Thread kyle.smith

One of two things is happening:

- PHP is crashing, maybe a memory leak, etc.

Or

- That while(true) loop is exiting, and the script is completing.

Would be interesting to know which, try adding this after the loop:
$fp = fopen('/tmp/test','w');
fputs($fp, 'My script left the loop and exited cleanly.  True ==
false.');
fclose($fp);

Back on my first point, have you kept an eye on the memory usage over
the 3 hours?  If your version of PHP has a memory leak with while() or
sleep() (would be odd), a bazillion iterrations could break the PHP
defined memory limit (8M by default) and cause it to exit abruptly.

Are you capturing the output anywhere?  For example, in Linux is it
being run from cron or another script?  Try redirecting STDOUT and
STDERR somewhere useful, i.e.:

php my_php_script > /tmp/scriptoutput 2>&1

(2>&1 means "output stream 2 [stderr] to the same place as stream 1")

Hope any of these crazy ideas are helpful...

Shouldn't be max execution time issue if he's running the CLI. Maybe
account limits? Maybe the above snippet isn't what's really happening...

I mean what purpose would the above script serve for 3 hours? Looks like
it's been dumbed down for us dummies on the list.

hi,

should it be this setting that allows the script to run forever?
max_execution_time = 0;

also when script runs from command line, max_execution_time defaults to zero.

hi,

maybe you should put
error_reporting(E_ALL);
ini_set('display_errors', true);

with the setting above, run the script
C:\php.exe D:\update\while_loop_script.php

you should see errors when script ends.

can some tell why the below loop stop running after some time.

$start=10;

while($start >run){

The webserver or php environment is probably terminating the script. It will
only run for the max number of seconds set in your php.ini file.

interesting points regarding college and programming..

my degrees bsee/msee covered alot more than pure programing.. as a double 
ee/cs, the ability to articulate an issue/problem, and bring to mind a cogent 
thought process was valuable. the ability to understand how different 
algorithms worked, and how code actually played with the lower intracacies of

I don't "dabble" in it either, unless you consider making my living from being 
a dabbler, in which case I'll continue to dabble and see the pay for it.  My 
alma-mater tried to stay current to some degree, but when they let someone who 
wrote the C++ book try to teach it, well they gave that person more rope then 
they needed.

Tedd, glad you got hooked on Phonics.  One of these days I hope from graduating

This is how I've always done it 'til now, but I think passing by
reference is a bit neater in its approach, and can be easier to read
when $value is itself an array or complex object.

Can you do that? I assume it would look like this:

Close. It actually looks like this:

foreach ($array as $key => &$value)  {}

This makes sense because for each  iteration of the loop, PHP places a 
copy of the key in $key, and a copy of the value in $value. Therefor, 
you are specifying with this code that you want it to place a reference 
of the value into $value.

www.ashleysheridan.co.uk



foreach ($array as $key => $value)

$value = a copy so won't change the original array
$array[$key] = the original

thus:

foreach ($array as $key => $value) {
 $array[$key] = do_something_with($value);
}

indeed but beware, using a variable named $value after such a foreach loop
in the same scope will lead to all sorts of things you don't expect.

Can you do that? I assume it would look like this:

foreach(&$array as $a) {}

it should be always something like

has someone already use such syntax ? i mean as the first one.

While you teacher technically is wrong, you probably could implement 
something using the next() and current() array functions, though you're 
best to just use a foreach loop. foreach was designed specifically as an 
array looping construct, so it's optimized pretty well.


Only thing to note with the foreach is that you are actually working on 
a copy of the array, so if you intend to modify it, pass it by reference.

I don't "dabble" in it either, unless you consider making my living from being 
a dabbler, in which case I'll continue to dabble and see the pay for it.  My 
alma-mater tried to stay current to some degree, but when they let someone who 
wrote the C++ book try to teach it, well they gave that person more rope then 
they needed.

the bulk of it self taught and via vast amounts of reading and many 
years of on the job experience (needs must), some formal education in 
the form of a year wasted getting a diploma whenst I was young (mainly 
as the topics covered where out of date and unused in general business).


HOWEVER, (a big one) I've recently converted, never really been an 
advocate of formal training until recently; I would highly recommend 
taking some certification courses (zend, sun, mysql etc), and some 
formal study on the finer details of programming / architecture.


If I could do it all again I'd do both, work to get experience and 
challeges, read the great books and the manuals, and get certified 
properly at the same time.


finally, using good tools makes a vast difference, for instance I use 
eclipse + pdt + zend eclipse debugger + svn + rse + bugzilla + mylyn + 
phpdoc + phpunit (adding in ant + cruise control to the mix soon for 
continuous integration)

I think it's a mixed crowd here. I have a Bachelor of Computer Science.
The various algorithms courses were some of my favourite courses in the
program along with parallel and distributed computing.

not using count() but instead looping the complete array is stupid,

just for fun:

$a = range(1,10);
for ($i = 0, $c = count($a); $i < $c; print($a[$i]."\n"), $i++);

... gives an idea of the power and flexibility of a for loop
constructor, i.e. you can pretty much write a complete program
using just a for construct without even defining a loop body.

Hi,

i'm on PHP training and our lector is telling us that to avoid counting an
array item amout thanks count($my_array), he tells we can do:
while($my_array)
{
 ... do something
}
but from experience this is an infinity loop...

it should be always something like
$count = count($my_array);
while($i <= $count)
{
...
do something
...
$i++;
}

has someone already use such syntax ? i mean as the first one.
thx.

  


Probably the easiest way for doing this is using foreach:

$a = array(1,2,3,4,5);

foreach ($a as $i) {
   print $i."";
}

This outputs:
1
2
3
4
5

This for e.g. gives an infinite loop:

$a = array(1,2,3,4,5);

while ($a) {
   print $i."";
   $i++;
}

So you are right because $a will always evaluate as true since it not 
empty. For these kinds of questions you should read the manual first and 
then ask here.

The while would work if you removed elements of $my_array inside the  
loop, but you would still need to be sure that it would eventually be  
empty.


I would guess that your lecturers point is that you shouldn't call  
count on every iteration as it's a waste of time. He may also be  
confusing while for foreach in which case I'd leave because you're  
unlikely to learn anything from him.

Just get the number from mysql_num_rows($resultado). It will return
the number of rows returned by the query and you can use it anywhere
as long as $resultado is a valid resource.

[PHP] while

2008-02-23 Thread Emiliano Boragina

Hi everyone

I am beginner

I have the following code:

 

";

 $resultado = mysql_query ("select * from alumnos where Curso like
'$buscar'" , $conexion);

 while ( $registro = mysql_fetch_row ($resultado)) {

   echo "";

   foreach ( $registro as $clave ) {

echo "" . $clave . "";

   }

 }

 echo "";

?>









 

I want to add a message when find results on the DB: Find n results, when
dont find results: 0 results.

How and where I must write the IF, and how I do for the n (number of
results) appear.

 

Thanks a lot!

Nice weekend!

The first time around the loop, both $key and $value are undefined, as
you're not setting them until the end condition.

But that's not a big deal as nothing gets done first time through the
loop except for $get_hloopRow1 getting incremented.

The next time through the loop, because $get_hloopRow1 is now not
zero, the first conditional gets executed. You add some html and the
first value from the array to $text to the string and incremenent
$get_endRow.

All subsequent times through the loop, nothing gets done because the
$get_endRow == 0 condition fails. $get_endRow never gets incrememented
again.

that help at all?

Yeah the last comment in my response detailsed your problem. Namely that
list() has no return value so the loop ends when it's return value is
checked since null juggles to false in boolean context.

Your subject line says "while-do" + array, following code contains a
"do-while" loop. We can't debug the script very well without a sample
input since we don't know how many times the loop "should" run. To debug
yourself, try using print_r() to see exactly what the following line of
code produces:

$options = explode(",", $armbase);

It's also useful for you to know that the list() function in your while
clause has return value void, AKA null, and so it will always be a false
statement and your loop will terminate on the first check.

Rob.

Hiya,

I have the following code ... which only seems to result in one item ...
which is incorrect ... can anyone spot my problem?

if ($armbase != "") {
$options = explode(",", $armbase);
$text .=  '';
$get_endRow = 0;
$get_columns = 8;
$get_hloopRow1 = 0;

do {
if($get_endRow == 0  && $get_hloopRow1++ != 0) {
$text .= '';
$text .= '';
$text .= "";
$text .= '';
$get_endRow++;
}
if($get_endRow >= $get_columns) {
$text .=  '';
$get_endRow = 0;
}
} while(list($key,$value) = each($options));

if($get_endRow != 0) {
while ($get_endRow < $get_columns) {
$text .=  ' ';
$get_endRow++;
}
$text .=  '';

$text .=  '';

The purpose of the code is to create 8 colums and populate based on the

I prefer 

echo '', $product_type, '';

Everybody else has told you to move the $i++; inside the while { } loop.

I'm not gonna tell you that.

I'm gonna tell you to get out a pencil and some paper, and "walk" through
your code, writing down exactly what data goes where, in which variables,
on each line.

Make yourself a nice big wide columnar sheet of paper tracking each variable.

LINE | $db | $result | $myrow | $num | $i | $product_type |
1
2
3
4
5  | db-link |
6
7  || db-result |
.
.
.

You need to do this.

Trust me.

You should put "$i++" into the while loop. And you should add an ";"
at the end of the echo line as well as at the end of "$i++".

[PHP] While and echoing HTML

2005-05-09 Thread Mark Sargent

Hi All,
this page,
http://www.freewebmasterhelp.com/tutorials/phpmysql/5
has the below code,

$first=mysql_result($result,$i,"first");
$last=mysql_result($result,$i,"last");
$phone=mysql_result($result,$i,"phone");
$mobile=mysql_result($result,$i,"mobile");
$fax=mysql_result($result,$i,"fax");
$email=mysql_result($result,$i,"email");
$web=mysql_result($result,$i,"web");
?>





E-mail
Website



echo "";
which I basically understand, except the html generation. I am trying to 
create something similiar, although, I think there are some errors in 
even perhaps my logic..?



Jumbo Status

$db = mysql_connect("localhost", "root", "grunger");
mysql_select_db("status",$db);
$result = mysql_query("SELECT ProductTypes.product_type_detail FROM 
ProductTypes",$db);
$myrow = mysql_fetch_array($result);
$num = mysql_num_rows($result);
?>


Product Type


$i=0;
while ($i < $num){
$product_type=mysql_result($result,$i,"product_type_detail");
echo ""
}
$i++
?>




I get the folowing error,
*Parse error*: parse error, unexpected '}', expecting ',' or ';' in 
*/var/www/html/products.php* on line *20
*
which is the $i++ section.

Cheers.
Mark Sargent.

Since mysql 4.1 you can use GROUP_CONCAT() function:
SELECT Act_date, Act_type_id,
LEFT( GROUP_CONCAT(Act_name
   ORDER BY Act_date
   SEPARATOR '|'),
  129 ) as Act_names
FROM activities GROUP BY Act_date, Act_type_id;
Act_names will be string containing the names separated by |
129 is the maximum size of Act_name * 2 + 1 for the separator.

Change your "ORDER BY" to : "order by Act_date"

That's the only way you're gonna get them in date order to get the NEXT
two in time.

Then you need to get just two of each kind, which SQL isn't really geared
to do, at least not easily.

Hopefully, you'll never have, like, *THOUSANDS* of upcoming Acts...

$next_two = array();
while (list($name, $type, $date) = mysql_fetch_row($getact)){
  if (!isset($next_two[$type]) || count($next_two[$type]) < 2){
$new_two[$type][] = "$name $date";
  }
}

You now have an array $new_two with indices of the Act's type, and values
of arrays of at most 2 entries, with "$name $date".

If you need $name and $date separated, you could use: array($name, $date)
instead of "$name $date" inside the loop.

You'll need to use some kind of loop to go through the $next_two array.

What I’m trying to do now is:

From the result array, pick from every different act_type_id
the two activities that will happen first and put them in 2 variables 

Eg. 

The two act_date with act_type_id 1

Should be stored in 

$Act1result1 and $act1result2

 

The two act_date with act_type_id 2

Should be stored in

I think this can be done with a loop in a loop but I always

Can someone help me on this?

Add the following lines:
global $apo;
global $row;
This will make it work for you but it's not the best solution. It's 
better to pass in parameters to the function rather than to rely on globals.


function hello() {
while ($apo->fetchInto($row)) {
print "hello 2";
}

I'm having difficluties finding out how this is related to php, but
anyway... this is a  simple joining of two tables.

so you have

  select b from table_1 where a = 2

and
  select d from table_2 where b = results from table_1

Thus

  select table_1.b, table_2.d from table_1, table_2 
   where table_1.b = table_2.b 
and table_1.a = 2


come to think of it, thats very much like an algebra problem.

If I understand you correctly, its sounds like you
want to do the following:

$sql = "
SELECT t1.b,
   t2.d
FROM Table_1 AS t1
LEFT JOIN Table_2 AS t2
ON (t1.b = t2.d)
WHERE t1.a = '2'";

So delete it or comment it out.
