Seems the sarcasm / attempted comedy was lost in translation!

Hello,
I had a thought today while walking...why do all ideas come while
walking under the sun rather than slouching in front of the LCD's glow?
Wouldn't it be cool to develop an application that allowed one to manage
Git via PHP? I'm thinking, sorta like how the PHPMyAdmin project helps
people manage MySQL via PHP.
The reach for PHPGitAdmin would prolly not be as great as it is for
PHPMyAdmin, b/c most hosting services do not let one run git (executing
shell commands), i assume.
I'm still new to Git and Subversion, after a few days of research I
think I'm more inclined towards Git. I am not exactly sure how the
PHPGitAdmin project would work, but I'm thinking aloud right now.
Maybe there is such a feature already available. I guess eclipse and
the git plug-in effectively accomplish a similar task, but this requires
people to have the eclipse framework rather than a browser and the i-net
(which everyone hopefully has).
What do you all think about this project?
Thanks,
dK

Ok, from memory:
<?php
fwrite(fopen('/tmp/counter', 'a'), '1');
?>
The 1 could be any single byte character I guess.

Hi all
I posted this on the PHP-db list, but it is sunday.. and with so
little traffic today, perhaps no one will mind if I post this here
too? (with hoped I'll get a quicker pointer?).
I'm translating some code from another server-side language into PHP,
and I need something that 'summarizes' results found from a MySQL
SELECT. I.e. -
$foundTrackingRows=mysql_query("SELECT...
while ($TrackingRow = mysql_fetch_object($foundTrackingRows)) {...
..such that the while loop only loops *ONCE per unique _date_ found
(regardless of the hour/min./sec.)* in my column which is of type
TIMESTAMP DEFAULT CURRENT_TIMESTAMP ON UPDATE CURRENT_TIMESTAMP
PRIMARY KEY
For example, if I have column values like these:
2009-08-01 07:01:00
2009-07-30 18:16:37
2009-07-30 17:49:06
2009-07-27 17:35:52
2009-07-27 17:24:21
2009-07-27 17:23:03
..then my while { loop would only fire 3 times.
I do my RTFM; can someone just give me a good point in the right
direction.
Thanks!

problem:
__ construct( $something ... variable argument list ){
parent::__construct( ??? );
}
I tried with func_get_args, but the problem is that it gives an indexed
array back.
lets say the argument list is mixed like this:
( "string", "string", array)
func_get_args will give this
[0] => "string"
[1] => "string"
[2] => array
the parent constructor works also with the func:_get_args function in ordfer
to handle variable argument lists
if u pass the array from func_get_args the parent constructor will reveive
after his func_get_args the following
array( [0] => array( [0] => "string" [1] =>"string" [2] => array( ....)
ok no problem so far. I thought just strip the key column of the array with
a function like this
function stripFirstColumn( $_fromThisArray ){
$b = "";
$_b = array();
foreach( $_fromThisArray as $value){
if( !is_array($value) ){
if( empty( $b )){
$b = $value;
// $_b[$b]="";
} else {
$_b[$b]=$value;
$b = "";
}
} else {
array_push($_b, $value); or $_b[] = $value;
}
}
return $_b;
}
BUT this results in an arry like this
array( "string", "string", [0] => array( ...))
HOWEVER u can create a propper array for this purpose by writing this :
$_a = array( "string", "string", Array( "string" => "string",
"string"=>"string"));
but there is no way to create the same construction by code unless I use the
eval() function what limits me to string objects only.
im really a senior coder (since 1982) but this gives me a headace. what do u
think?

I don't understand completely your problem, but think that something
like this may help you:
<?php
class A
{
function __construct()
{
var_dump(func_get_args());
}
}
class B extends A
{
function __construct()
{
$args = func_get_args();
call_user_func_array(array(parent, '__construct'), $args);
}
}
$a = new B(1, 2, 3);
?>
This will output:
array(3) {
[0]=>
int(1)
[1]=>
int(2)
[2]=>
int(3)
}
As expected.
The key is using call_user_func_array in combination with
func_get_args to call the parent constructor without knowing the
number of parameters.
Let me know if that helps.

Look into the Reverse module of PEAR MDB2.

I know I CAN hack something together but I hate to reinvent the wheel.
I want to be able to compare the structure of two different clients
databases that might be on different servers that are firewalled away
from each other. Given the two structures it will list all the SQL
commands needed to make the database structure the same.
In a perfect world on one side you would pull up a PHP page that does
a "generate structure" which would create a downloadable file which
you could then upload to the other system which would then give a
listing of the SQL commands needed to make the local structure match
the uploaded structure.
Thanks in advance...

I'm creating a form with variable number of entries (user controlled) where
each entry consists of some input fields. For most input types, appending []
to their names is enough to allow me processing each entry. So, for
instance, if there are 3 entries with field name[] and email[], they can be
accessed as:
name = Array(
0 => 'name1',
1 => 'name2',
2 => 'name3'
)
email = Array(
0 => 'email1',
1 => 'email2',
2 => 'email3'
)
However, this isn't the case for radio buttons. Let's see a common usage:
sex determinition. Using sex[] will make the one in an entry to behave
dependently to another. This is due to the radio button behavior to group
choices based on name.
How can I make a radio button in one entry to behave independently from the
one in another so that it can be accessed as name and email above?
