Programming :: PHP - How To Parse Data Into Variables
Apr 17, 2011
My php knowledge is very poor (only worked with strings so far), and I am faced which a task that is a real challenge for me: I have a variable, that contains data of different type, in this order: byte, byte, string, string, string, string, short, byte, byte, byte, byte, byte, byte, byte, string.
Strings are of variable length. How could this data be parsed into variables of the right type, and then all converted to strings? What are the functions to use? Strings are unicode ones, and they are delimited by "
When I chose options 1 thru 3, that executes with no problem (Menu=Download does not work). The program sees into field four, but field four is not able to see outside itself. For instance:
Code:
Download:chan: Download:pitm:1:echo $numpi. Return to Main Menu Download:pitm:2:
[code]....
is used to generate a numbered list of channels. It could be four or 40. Whatever the number is, I want the next line to read, for example, 32. Return to Main Menu.
Code:
num
is the variable in the script I use to number the list of channels. The number following Download: pitm: is numpi, which should be added to num. How do I take
I need to parse through a file which contains timestamps of transactions. What I am trying to do is come up with a Max Transactions Per Second (TPS) value. I was thinking that creating an array variable would be the way to go, but I'm having problems determining even how to start.
When trying to access my HTC Vogue via bluetooth, I can view all my files EXCEPT the music directory I made on my sd card (which is actually the one i wanted...). When trying to view it, nautilus gives the following error:
Code: The folder contents could not be displayed. Couldn't parse the incoming data. A quick google revealed [URL]../+s...ez/+bug/310231 however I'm fairly noobish when it comes to compiling so could someone perhaps direct me with the commands? Edit: Sorry forgot to mention its the second post on that website.
what is the best command to use to parse strings?I have a variable $str and need to parse this string.Can you provide an example of the command used to get a substring of $str based on the index values of start and end
I have to parse a file containing billions of records and populate them in the Data structure. I have used a lot of C++ class and creating objects of the class I am storing the information retrieved by parsing the file.
Now as the file become huge and number of objects become very large my code is getting bad_alloc error as it is not finding any space avalable in the heap for allocating new object.
To run a parallel chemistry program, I need to build the host list. The cluster already has SGE(grid engine) installed and it generates a host list file with the following contents:
The important bits are hostname(ex compute-1-1) and number of cpus to use(ex 2). And for this program, it wants them in this form, a shell variable: HOSTLIST=hostname:cpus=X hostname:cpus=X .... I've tried this script, but it doesn't work
I have a basic HTML file set up which allows my to input some data. I have a MySql database set up behind the scenes with a table for this information to go in. When I click the submit button in my HTML file this PHP file opens and it comes up with "Parse error: parse error in C:wampwwwcomp39xinsert_student.php on line 32"Here is my code I am using in the PHP file:-
<html> <head> <title>COMP 39x FInal Year Project - Student Added?</title>
I can define all variables in tcl programming in a file for instance var.cfgand source the same file in my tcl script such assource var.cfgIs this possible in perl too?
I don't think this is a "perl one-liner" of find and replace. I'm trying to auto-fill some information in a listing of files. The simplest example is that in the files the following exists:
I would want the script to find this and populate it with something like -- Date : 20101004-1758
I have a few more similar fields to autofill, and I'd like to do this from within a larger perl script I'm developing to process these files. So, how I perform in-place file modification from within a perl script?
I'm trying to figure out how I can get a request count per CIDR/24 from an apache log in combined format - e.g.: Code: 24.147.44.122 - frank [10/Oct/2011:13:55:36 -0700] "GET /apache_pb.gif HTTP/1.0" 200 2326 "[URL] "Mozilla/4.08 [en] (Win98; I ;Nav)"
I'm stuck using BASH for this and I generally write everything in Python, or even Perl if necessary so BASH isn't the most comfortable for me. I've got enough to extract the IPs and get a count I just need a slick way to come up with a sum on a per CIDR basis.
There is a file with that format of each models' information.I don't think that's good format, but I cannot change that format. I needed to modify the model name, 'model = xxx' as 'model = abc'.And I don't know how to parse and modify 'model = iii' and 'model = ddd'.The only clue to parse 'model = ddd' is the second 'model = ' after the second 'system information'. But how to parse the second keyword?Is it possible with 'sed'?I sometimes have to modify the information of the file.using shell script if possible.Python is ok. (Shell script is better for me.)
I would like to extract Room number, Lastname,Firstname,invoice (205880080),arrival date, departure date, and total(229.46). Can you at least give me a hint on how to proceed? I have tried a lot but I am stumped from the beginning.

I'm trying to write a script that will spider a particular webpage that shows the current inventory for their products. I need to figure out the optimal method of parsing the web page, and extracting the <td> line for the "qty" for "Product 2":
I am trying to make a perl script which reads data from a file and parse it. The data in the file has the following syntax
Code: Device Physical Name : Not Visible Device Symmetrix Name : 1234 Device Serial ID : N/A Attached BCV Device : N/A Device Capacity
[Code]...
Each unique record starts with "Device Physical Name". So, I have a set of records within "Device Physical Name". I want to read this set of records starting from "Device Physical Name" and ends up till next "Device Physical Name". Offcourse FS is ":", and I just want to print/or later put info in a csv file.
I am trying to think of a logic where my file contains some data I had to read and do some processing. Issue is that file contains data multiple times. For example:
::::::::::: var1=value1 var2=value2
[code].....
I have to read first paragraph of variables and do some processing and then move on until the end of file. Variable names are same in whole file but for each paragraph the value is different. I can't think of a logic to attain this task. How can I do it? It should be a simple bash script, but I am not able to work out.
