[PHP] iterating and changing value of an array using foreach and references - PHP 5.2.3
Hi,
Here's an interesting observation i noticed while using foreach to
iterate on arrays using
references for it's values.
-
PHP version
$ php -v
PHP 5.2.3 (cli) (built: Jun 8 2007 14:31:21)
Copyright (c) 1997-2007 The PHP Group
Zend Engine v2.2.0, Copyright (c) 1998-2007 Zend Technologies
-
Source code
15, 'ar_needed' => 'no');
$cat1[16] = array('tid' => 16, 'ar_needed' => 'no');
$cat1[17] = array('tid' => 17, 'ar_needed' => 'no');
// print it
print "\n\$cat1 = ";
print_r($cat1);
print "\n";
// iterate using foreach and reference
foreach ($cat1 as $k => &$v) {
if ($k == 15) {
$v['ar_needed'] = 'yes'; // dummy change
}
}
// print array
print "\n\$cat1 = ";
print_r($cat1);
print "\n";
// reiterate
foreach ($cat1 as $k => $v) {
print "\$k = $k\n";
print "\$v = ";
print_r($v);
print "\n";
}
?>
-
OUTPUT
$cat1 = Array
(
[15] => Array
(
[tid] => 15
[ar_needed] => no
)
[16] => Array
(
[tid] => 16
[ar_needed] => no
)
[17] => Array
(
[tid] => 17
[ar_needed] => no
)
)
$cat1 = Array
(
[15] => Array
(
[tid] => 15
[ar_needed] => yes
)
[16] => Array
(
[tid] => 16
[ar_needed] => no
)
[17] => Array
(
[tid] => 17
[ar_needed] => no
)
)
$k = 15
$v = Array
(
[tid] => 15
[ar_needed] => yes
)
$k = 16
$v = Array
(
[tid] => 16
[ar_needed] => no
)
$k = 17
$v = Array
(
[tid] => 16
[ar_needed] => no
)
-
As seen in the above output all the print statements give expected
output except the last
set in the 2nd iteration
$k = 17
$v = Array
(
[tid] => 16
[ar_needed] => no
)
the $k looks fine but the $v is not correct for some reason. Any clue
what could be wrong
here ?. Also, in the 2nd iteration of the name of the variable is
changed from $v to $v1
it displays correctly
$k = 17
$v1 = Array
(
[tid] => 17
[ar_needed] => no
)
Thanks.
Yashesh Bhatia.

[PHP] Cookies and sent headers
If built a simple login page and store any information within
$_SESSION's. Yet I'd like to move these into cookies but I always get an
error about sent headers. Is there a way to circumvent this problem
without changing too much in the page?
The setting of the cookies happens just at the end of the page.

if (!empty($Permanent)) {
$expires = time()+ 365 * 86400; // 365 days

You best option would be to go through all of your include'd or require'd

php tags. Those are often the cause for such problems. The easy way would
indeed be to use output buffering. In that case, put the call to ob_start();

can look into the ob_start(), ob_flush() functions to use output buffering

RE: [PHP] Cookies and sent headers
The commands start and use an output buffer, a chunk of memory that stores all
the output on the server until the ob_flush, the buffer flush, function is
called. You need to be aware that in high load situations this may adversly
affect performance since it loads the servers memory, also be aware that you
may hit a memory limit for large pages. This is server / OS depandant so you
may want to read up on server documentation

Re: [PHP] Cookies and sent headers
On a sidenote, 99% of the world never calls ob_flush (or any such
function) since PHP flushes the buffer automatically at the end of its
execution.
The reason why setting cookies for you doesn't work is because of the
way a HTTP response is structured. It consists of 2 parts: header and
body separated by 2 new lines (\n\n). It is _required_ that _all_
headers come _before_ the body. Cookies are actually headers (a
set-cookie: [...] header) aswell as any headers set via php's header()
function. Any output made by the script (be it a single whitespace, a
bunch of text, etc.) will automatically flush the headers, followed by
the separator (\n\n) followed by the specified output. After that has
been sent, everything outputted will be dumped into the body of the
response (simply because you can't "go back" to the headers which were
already sent earlier), so you can't set cookies (which are headers
themselves).
So, why does output buffering help here? Simply put, instead of dumping
headers and any other output directly to the client, PHP buffers it all
into memory. As such, since it hasn't been sent yet, PHP can still
alter/add headers even though it also has body-output. Once it receives
the command, PHP will send all headers, the separator and the output to
the client. This is done when PHP encounters an ob_flush or ob_end_flush
call, _and_ when the script has finished execution automatically.
The documentation seems pretty clear to me, however, if you feel it
should be clarified better, feel free to send a patch to the
[EMAIL PROTECTED] list.

RE: [PHP] Cookies and sent headers
Hi,
Its not the problem of cookies. Its problem of redirection or the
parent.location.replace function. I mean if you already output something on
the page and tries to redirect then this problem happens.
Redirect before outputting anything on the page.. like space is also an
output.

[PHP] Capturing shell command output.
HI,
I am working on a PHP project that interacts with command line utilities.
My php is running by apache. Means I am not running any php CLI.
here is the function that I am using for capturing command output.
function run_command($comamnd){
$ret=`$command 1> COMMAND.OUT 2>1`;
$contents=get_file_contents("COMMAND.OUT");
return $contents;
}
The function does not work. If I use any shell command like ls, cat,
echo, set. it works.
But If I use any utility like, mpg321, cd-info. It does not work. It
outputs a blank string.
I used system(), passthru() with both "2&>1" and "2>1". But no out put.
All the time, its blank.
Even I used a shell script "run.sh"
run.sh contents:
=
#!/bin/sh
sh COMMAND 1> COMMAND.OUT 2&>1
cat COMMAND.OUT
echo 0 > COMMAND
=
I called this script by this function
function run_command($command){
$h=fopen("COMMAND","w");
fwrite($h,$command);
fclose($h);
ob_start();
passthru("./run.sh");
$ret = ob_get_contents();
ob_end_clean();
return $ret;
}
and by this.
function run_command($command){
$h=fopen("COMMAND","w");
fwrite($h,$command);
fclose($h);
return system("./run.sh");
}
Please help me. or show me some way.

Re: [PHP] Capturing shell command output.
You may want to look into shell_exec, which executes a command and returns
the output. If you're accepting arguments from user input, don't forget
proper use of escapeshellcmd and escapeshellarg ;-).
Something else that might cause your commands from failing, is that the
utilities are not inside apache's PATH - trying to call them by there
absolute filename can help out. Have you inspected your error_log? There
often tends to be a lot of useful stuff in there.
Good luck!

Re: [PHP] Photo upload framework/library for PHP

Redirect before outputting anything on the page.. like space is also an

[PHP] Delete row in a lookup table
Hi all, Is it not considered good practice to have a primary key on a lookup table for a database? I have 3 tables setup, games, memberleagues and members. The memberleagues table holds the id of the games table and members table. The problem I have is that Im not sure how to delete a row from the memberleagues table without a primary key. If its not considered bad practice I could add a primary key to the memberleagues table and be done. Anybody have any tutorials on how to write the php for this? _ Messenger Café — open for fun 24/7.

the javascript code can definitely change to head("location: whatever.php")
for redirection, if that's the solution, that would be the way to go, but if
you're encountering quite similar problems later you can try ob_start() or
whatever that was recommended in the comments before M. Sokolewicz's
bullshitting comment.

Re: [PHP] Delete row in a lookup table
Whether or not it's good practice depends on who you ask. :-)
Every table should have a primary key. Primary keys, however, may span
multiple columns. That's perfectly legal. In some cases that primary key
may span every column, but generally that's a sign of bad design unless
you're talking about a table that just relates one table to another (many to
many relation).
The question is whether it's better to have a surrogate key[1]. That is, a
unique integer value that has no meaning itself beyond being a unique key.
For example, in pretty much any authentication system the username will be
unique, and therefore could easily be used as the primary key. Other tables,
then, would reference back to the user table using the username as the
foreign key.
There's pros and cons to surrogate keys over "natural" keys. See more links
below that I don't feel like repeating[2].
Personaly I tend toward surrogate keys in most cases for entities, but not for
relationships. In your case, then, no, I would not have a surrogate key on
the membersleagues table. Instead I'd define (game_id, member_id) as the
primary key. You can absolutely then DELETE from membersleagues WHERE
game_id=4 AND member_id=3. Or just delete by one or the other. You don't
have to have a primary key defined in order to be able to DELETE, it's just
frequently simpler if you do. You can write a WHERE clause on anything.
In practice, I generally find it easier to do a delete/rebuild than to try and
track an extra surrogate key. That is, I'd do something like:
$db->query("DELETE FROM foo WHERE thing_id=5");
foreach ($foo->things as $thing_id) {
$db->query("INSERT INTO foo (foo_id, thing_id) VALUES (5, $thing_id)");
}
(Actually I wouldn't do that. I'd use prepared statements because just
inserting the variable into the string like that is a security risk. Don't
do it. It's just easier to explain without the prepared statement for now.)
That should be fine unless $foo->things is rather large or is very frequently
edited (for some defintions of large and frequent).
Cheers.

Re: [PHP] Cookies and sent headers
M. Sokolewicz wrote: On a sidenote, 99% of the world never calls ob_flush (or any such function) since PHP flushes the buffer automatically at the end of its execution. I'll keep the ob_end_flush just for showing what's going on, but thanks for the hint. The reason why setting cookies for you doesn't work is because of the way a HTTP response is structured. It consists of 2 parts: header and body separated by 2 new lines (\n\n). It is _required_ that _all_ headers come _before_ the body. Cookies are actually headers (a set-cookie: [...] header) aswell as any headers set via php's header() function. Any output made by the script (be it a single whitespace, a bunch of text, etc.) will automatically flush the headers, followed by the separator (\n\n) followed by the specified output. After that has been sent, everything outputted will be dumped into the body of the response (simply because you can't "go back" to the headers which were already sent earlier), so you can't set cookies (which are headers themselves). Thanks, now it's understandable. So, why does output buffering help here? Simply put, instead of dumping headers and any other output directly to the client, PHP buffers it all into memory. As such, since it hasn't been sent yet, PHP can still alter/add headers even though it also has body-output. Once it receives the command, PHP will send all headers, the separator and the output to the client. This is done when PHP encounters an ob_flush or ob_end_flush call, _and_ when the script has finished execution automatically. The documentation seems pretty clear to me, however, if you feel it should be clarified better, feel free to send a patch to the [EMAIL PROTECTED] list. - Tul O.

I'm aware that using Javascript within a PHP code block doesn't seems
logical yet I haven't known header ('Location...). In my case I could
easilly do without redirection but just exit and fall back on the
calling page. Yet I want to remove the login page from the browser
history. Does the header function have the same effect?
