Programming :: PHP - Sort Multi Dimensional Array
Apr 30, 2010I have a multi-dimensional array like so:
Code:
Array (
[0] => Array (
[0] => Eleven
[1] => NumberEleven
[2] => 11 )
[1] => Array (
[0] => Twelve
[1] => NumberTwelve
[2] => 12 )
[2] => Array (
[0] => AnotherEleven
[1] => Eleven,Again
[2] => 11 )
I need to sort it by array[ $key ][ 2 ] so that it is sorted like so:
Code:
Array (
[0] => Array (
[0] => Eleven
[1] => NumberEleven
[2] => 11 )
[1] => Array (
[0] => AnotherEleven
[1] => Eleven,Again
[2] => 11 )
[2] => Array (
[0] => Twelve
[1] => NumberTwelve
[2] => 12 )
I've looked at the php array docs the closet thing I found was array_multisort which won't work for my above requirements, does anyone have any insight to how to sort this way?

Programming :: Converting A PHP Array Into An HTML Array?

Programming :: SORT Command Versus Unix SORT
May 4, 2010We switched from unix to linux and we have an old report that extracted data from a database, output to an ascii file and then sorted the results in the file based on different arguments. The report now blows up when it runs,and I can only guess it is because the options for sort on linux differ slightly from unix.For example, here is one of the commands issued from within the report app that ran on the old unix box:
if sort-sequence = "descending" then
'sort -t~" -f +3.0f -4.0 +5.0r -6.0 -f '
else
'sort -t~" +3.0f -4.0 +1.0f -2.0 -f'
I will eventually rewrite the report to store the data in a local table, but I can simply adjust the options to suit the requirments of linux. Basically, I need to know if this can be a quick fix for the short term.

View 5 Replies View RelatedProgramming :: Double Data Type Mantissa?
Nov 23, 2010in c/c++, double is usually 8 bytes. It has a 52-bit mantissa (or significand, or base), an 11-bit exponent, and a 1-bit sign. My question is: is the mantissa a 52-bit integer? Or is the decimal point just after the first bit. Meaning: if the mantissa was 1000110011100011 (in binary) would that make the value of the mantissa (assuming the exponent was 0) 1000110011100011, or 1.000110011100011? (in binary)

View 14 Replies View RelatedProgramming :: C Function To Reverse The Byte Order In A Double?
Aug 12, 2010I'm trying to write an extension to PHP which means coding in C. I'm really really rusty at C coding and was never very good at it.
Can anyone propose an efficient, safe, and [hopefully] future-proof way of reversing a double? Keep in mind that it should work on as many systems as possible and on 32- and 64-bit systems (and on ???-bit systems in the future?). Will the size of a 'double' ever change or will it always be 8 bytes?
I've tried this and it doesn't work...the compiler complains about "invalid operands to binary" because I'm trying bitwise shiftw on a non-integer.
Code:
x = (x>>56) |
((x<<40) & 0x00FF000000000000) |
((x<<24) & 0x0000FF0000000000) |

Programming :: Double Pointers / Matrix GCC (fill It One Column With Zeros And The Other With Ones)
May 26, 2011I have a 10x2 matrix, I create said matrix and fill it one column with zeros and the other with ones, now when I print the matrix I get this:
column 1:
0,0,0,0,0,0,0,0,1,1
column 2:
1,1,1,1,1,1,1,1,1,1
The first two rows of the second column are being replaced into the last two rows of the first column, now I even checked in visual studio and it works fine there. A friend tried my code and he gets it even worse:
column 1:
0,0,0,0,1,1,1,1,1,1
column 2:
1,1,1,1,1,1,1,1,1,1
As far as I've seen it must be a problem with GCC, unfortunately I need to have this up and running in GCC no matter what.

Today, when I turned it on and tried to boot into Fedora 12, I got the following error (just once, it just locked up at various points during the splash screen after this once):

All the seemingly missing letters were really missing, not my typos.
As you can see, kernel version is 2.6.32.11-99.fc12.x86_64 and my laptop is a Sony Vaio TZ 250N (Core 2 Duo ULV 1.2GHZ). Note that with the other remaining kernels from the updates, nothing ever happened other than the locking up. The core temperatures hover pretty high, about 55-60C peak but this is still below the critical temp. Memtest came up clean when the problem first started happening.
