Best way I can think of is to iterate the entire thing and keep a count
as you do. I'm not aware of any functions that can do what you need
there.

How about this... Using a slightly modified array that you posted, I came up
with this in about 10 minutes
<pre>I am working with the following data structure
<?php
$in = array(
0 => array(
0 => array('Flight Number', 'flight_number'),
1 => array(
0 => array('Timestamp Departure', 'timestamp_departure'),
1 => array('Timestamp Arrival', 'timestamp_arrival'),
)
),
1 => array('Departure City', 'departure_city'),
2 => array('Arrival City', 'arrival_city'),
);
print_r($in);
echo "\n\n";
$max_depth = 0;
$cur_depth = 0;
function max_array_depth($ar) {
global $cur_depth, $max_depth;
if ( is_array($ar) ) {
$cur_depth++;
if ( $cur_depth > $max_depth ) {
$max_depth = $cur_depth;
}
foreach ( $ar AS $row ) {
max_array_depth($row);
}
$cur_depth--;
}
}
max_array_depth($in);
echo "Max depth of array is: {$max_depth}";
?></pre>

Globals are dirty for this kind of recursive utility function. Here's a
cleaner example:
<?php
function get_array_depth( $array )
{
if( !is_array( $array ) )
{
return 0;
}
$maxDepth = 0;
foreach( $array as $value )
{
if( ($subDepth = get_array_depth( $value )) > $maxDepth )
{
$maxDepth = $subDepth;
}
}
return 1 + $maxDepth;
}
?>
Cheers,
Rob.

Jochem is right, Bob and Jorge are wrong.

That's not really proof of anything, it's just an archived email from
this list...

Well, firstly it's an archived email from the *internals* (i.e. PHP developers)
list, not this one. And secondly it's from someone whom I trust to know what
he's talking about. If I looked, I'm sure I could dig up several similarly
definitive (but less recent) pronouncements from PHP "names", including Rasmus
himself.
In fact: http://marc.info/?l=php-internals&m=123969574312781&w=2

Well, that's their prerogative, but I believe they are wrong. Short tags
cause more problems than they will ever solve, and should be removed
from the language ASAP. I would classify that as a design flaw.
In the meantime, since we are upgrading our pages to XHTML, we are
replacing the short tags wherever they occur.

i have a problem of reading values from excel file via
spreadsheet_excel_reader which is a php class used to manipulate excel
files.
$data = new Spreadsheet_Excel_Reader();
$data->setOutputEncoding('CP936');
$data->read("d:\\tmp.xls");
$rows=$data->sheets[0]['numRows'];
$cell = $data->sheets[0]['cells'][1][1];
if i type many rows,say 1000, in the tmp.xls, it can read, $rows shows 1000,
however, 1000 rows of data are copied from another excel file and these
cells may have different background or other changes that differ from normal
cells, it fails to read.the variable $rows shows nothing....what i can do
now is to split these data into small groups, small enough to be read, it
really takes plenty of time.
i dont know why, has somebody met this problem ever?

If it's just the data you need, try using a csv file instead. The Excel
format is closed, and as such, the PHP classes won't have full support
for all of it's features. It seems like formatting is causing the data
to be written to the spreadsheet differently maybe.

Be careful. .BAT files are not executable, but you don't need to put
the command line processor in front do you?
You can quite easily turn ...
C:\PHP5\PHP.exe -f C:\Pathed\Directory\Script.php -- -script_arg1 -script_arg2
into
Script -script_arg1 -script_arg2
No php.exe, no .php, no -f
See http://docs.php.net/manual/en/install.windows.commandline.php
You can even turn php scripts into filters ...
Script -script_arg1 -script_arg2 | Script2 -script_arg1 -script_arg2
sort of thing.
