I've commented every line so that any of you could see if I'm interpreting

I have two questions about this code, that hopefully someone on the list
could explain:
1)
Why do we need to remove the last array item? (on line 32):
array_pop($urlStack);
On line 20, $url creates an URL path that includes the $cat path. Once you've
completed iteration on all children of $cat, the url path should no longer
include $cat path, thus it is removed from $urlStack.
2)
Why we print the closed tag of the li element, after the recursive call? (on
line 29)
echo /li\n;
Line 29 is closing the li element that was opened on line 23 for $cat.
Thanks a lot in advance,
Márcio
-Lex
Thanks a lot. I knew that:
“Line 29 is closing the li element that was opened on line 23 for $cat.”
My question intend to be more like:
Why that line to close the li element is *after* the recursive call?
Somehow, it seems that instead of creating something like this:
ul
liitem1/li
liitem2/li
liitem3/li
/ul
We are doing:
ul
liitem1
liitem2
liitem3
/li
/ul
Say you have a tree menu that contains :
$arr = array('item1' = 'Item 1', 'item2' = array('item2a' = 'Item 2a',
'item2b' = 'Item 2b'));
$urlStack = array('category');
When you call the tree() function with the above $arr values, the function acts
as follows:
1. First time through the function, the opening ul element is printed
2. First time through the foreach loop sets $cat = 'item1' and $val = 'Item 1'.
3. As this is not an array, the else condition prints liItem 1/li
4. Second time through the foreach loop sets $cat = 'Item 2' and $val =
array('item2a' = 'Item 2a', 'item2b' = 'Item 2b').
5. As this is an array, the if condition prints lia href=''Item/a and
calls the tree function recursively
6. Second time through the tree function, another ul element is printed and
the two sub items are printed as lisub item/li as they do not contain
additional arrays. Tree function ends by printing the closing /ul tag.
7. The foreach loop from step 5 continues and prints the closing /li. Tree
function ends by printing the closing /ul tag.
The output from calling tree($arr, $urlStack) would thus be:
ul
liItem 1/li
li
a href=?path=category/Item 2Item 2/a
ul
liItem 2a/li
liItem 2b/li
/ul
/li
/ul
Perfectly clear. Thanks a lot Lex. :)

Hey,
You can do it this way as well

br / input type='Button' value='Edit' width='100px'

DeleteChannelAndAllOfItsFeeds()\ / br / br

So you can escape double quotes by \ (slash)
try this .. It will work...
you can escape any special character that you want to use as it is by
prepend it by \

I posted the current RHEL version because, personally, I would look at the latest release of one of the biggest Enterprise class Linux vendors before deciding on a PHP version. The larger distros only tend to upgrade packages when required because other packages need them or when a security issues has been discovered. Other times they will patch in security fixes applied to packages. The tradeoff here is that you get something older but the system you receive is solid.

There are very good reasons why a 'long time supported' build does not keep replacing packages all the time. It is gauranteed NOT to change them, so compatibility problems introduced by PHP such as the 'date' problem will not come up and bit ANY of their customers. I believe that there is a new version due on a couple of 'long time supported' distributions, but the current 'instability' with PHP5.3 potentially requiring changes to deployed applications is the sort of thing that these builds are supposed to avoid. I'll be staying with 5.2.x for a while simply because I know that is stable with my current code base.

[PHP] Custom function for inserting values into MySQL
Okay friends, I have been wondering about writing a simple function that
will help me with my MySQL inserting. Not because I need to save time and
space, but because I wanted to.
I wrote a function for inserting 10 values (I have not been able to come up
with an idea how to make the number of values I'm inserting variable, so I'm
sticking with ten).
This function takes 22 parameters: #1 is the table name, #2-21 are the row
names and the values, and #22 is the integar string.
The first 21 parameters are self-explanatory, the 22nd is a string of values
that need to be inserted as an integar, basically, not adding single quotes
around the value. Eg. $value2 = 5, not $value2 = '5'.
I am very hesitant to try this one out on my database, I've got tables of
important information and don't want to, I don't know, inadvertantly throw a
wrench into the works, AND I want to open up a dialoug about custom PHP
functions for working with MySQL, for the fun of it!
Here is my 10 value function for inserting data into a MySQL database table.
function insertinto10($table, $field1, $value1, $field2, $value2, $field3,
$value3, $field4, $value4, $field5, $value5, $field6, $value6, $field7,
$value7, $field8, $value8, $field9, $value9, $field10, $value10, $int =
NULL)
{
if (isset($int))
{
$sPattern = '/\s*/m';
$sReplace = '';
$int = preg_replace($sPattern, $sReplace, $int);
$pieces = explode(,, $int); // $pieces[0], $pieces[1] - each equal to
value numbers that are integars
$length = count($pieces);
// call custom function to create associative array eg. $newarray[2] = 1,
$newarray[4] = 1, $newarray[5] = 1 . . .
$integarArray = strtoarray($length, $int);
}
$valuesArray = array($value1, $value2, $value3, $value4, $value5, $value6,
$value7, $value8, $value9, $value10);
foreach ($valuesArray as $key = $value)
{
if (isset($integarArray[$key]) $integarArray[$key] == 1)
{
// INTEGAR VALUE
$valuesArray[$key] = mysql_real_escape_string(stripslashes($value));
}
else
{
// STRING VALUE
$cleanValue = mysql_real_escape_string(stripslashes($value));
$valuesArray[$key] = '{$cleanValue}';
}
}
$result = mysql_query(INSERT INTO `{$table}` (`{$field1}`, `{$field2}`,
`{$field3}`, `{$field4}`) VALUES ({$valuesArray[1]}, {$valuesArray[2]},
{$valuesArray[3]}, {$valuesArray[4]}, {$valuesArray[5]}, {$valuesArray[6]},
{$valuesArray[7]}, {$valuesArray[8]}, {$valuesArray[9]},
{$valuesArray[10]}));
return $result;
}
You may find copying/pasting into your favorite code-editor helps make it
more readable.
Do you see any major hangups or screwups on first glance? And is my fear of
trying this out on my database unfounded? Does this even seem that useful?
RE: [PHP] Custom function for inserting values into MySQL
Do you see any major hangups or screwups on first glance?
Yes.
There is so much wrong with this I don't even know where to begin...
This function takes 22 parameters: #1 is the table name,
#2-21 are the row
names and the values, and #22 is the integar string.
Dude. Seriously? TWENTY TWO parameters.
Use this for variable number of parameters:
http://us2.php.net/manual/en/function.func-get-args.php
Or how about using an array/hash as your second parameter with the
field=value pairs.
Which is astonishing since you have the concept of an array with this hack:
$valuesArray = array($value1, $value2, $value3, $value4, $value5,
$value6, $value7, $value8, $value9,
$value10);
foreach ($valuesArray as $key = $value)
The word you're looking for is INTEGER not INTEGAR.
And is my fear of trying this out on my database unfounded?
No. Don't use it.
Does this even seem that useful?
No.
Your function is so very limited in scope and use. You're better off writing
a wrapper around the SQL functions and submit direct SQL as the string
parameter to the function. See attached db.inc.php.
You would also be better served using a method/function such as my
base.class.php::sync() which will insert or update a row.
The attached code is about a year old or so and has since been refined
further, but this should give you a good place to start.

Re: [PHP] Custom function for inserting values into MySQL
I would take a look at some of the frameworks like codeignter to see
how they do things.
But like Davied mentioned a simpler way to handle the passing into the
function would be
Function save($table, $data)
Where data is an array of key value pairs which takes your 22
parameters down to 2.
The array could look like
$data = array('id' = 1, 'name' = 'bob' ...)
