Extracting data from columns in a textfile with headers...
I should mention that I have the contents of the files stored in arrays. I just want to extract an entire column from each of the arrays. -
Extracting data from columns in a textfile with headers...
I have a text file in the following format: HEADER1 HEADER2 COL1 COL2 COL3 COL4 COL5 With data in each column. What I'd like to do is extract, for example, all data in COL2 and COL4...and write those columns to another file. I also need to ignore the headers that appear before the data... -
Perl Split Function
I'll give this a shot when I get back tonight. Thanks so much for your help, Travis! I greatly appreciate it. You da man. -
Perl Split Function
...is the code: #!/usr/bin/perl open (WARNING, "/home/josh/warning.txt"); @arwarn = <WARNING>; $stwarn = join('', @arwarn); if($stwarn =~ m/LON(.*)TIME/) { # I've also tried m/LON(.*)\nTIME and \r, etc and it works in some cases when those appear # $coords = $1; } @metdata = split(/\s+/... -
Perl Split Function
Thanks much, guys! That really helps. I seem to be losing the last longitude value in both methods, but that may be a consequence of my previous code. I'll have to look over things in more detail later. But it definitely gets me further than I was before. Thanks so much! -
Perl Split Function
To clarify, I meant I want to store all latitudes in an array and all longitudes in an array. Not each. Sorry for the confusion. -
Perl Split Function
...and all LONs the even elements. Any suggestions and code assistance for how to use split to do this would be appreciated. Thank you. #!/usr/bin/perl open (WARNING, "/home/josh/warning.txt"); @arwarn = <WARNING>; $stwarn = join('', @arwarn); if($stwarn =~ m/LON(.*)\nTIME/) { $coords = $1; } -

Perl Regular Expressions
I was thinking perhaps I could use a loop to store each value in an array, and then access the values by element. But I'd still need some help getting the right pattern. -
Perl Regular Expressions
It's been 2 years since I've done any work with regex in Perl so I'm hoping someone can offer a suggestion. I'd like to save all values in a text file (that's stored in array) between two keywords: "LON" and "TIME", into variables. The problem is I'd like to save each value to its own variable... -
Passing Session Variables From One Script to Another
Thanks! I actually just did that, although a little differently but the same concept. In the one script I used $location = $_GET['foo'] and in the other script I put "script.php?foo=.'$location.'"; I appreciate it! -
Passing Session Variables From One Script to Another
The hosting service I am using does not permit the use of registering globals. But I need to pass a variable with a constant value to other scripts that are called. I've tried: <?php session_start(); $location = $_GET['location'] // Passed in from a webform. session_register("location")... -
Failed to Open Stream
Well, it turns out that it was indeed the host. The site claimed they allowed fopen but it turns out last week they decided to disable it for outgoing connections from their server. I ended up getting it to work fine when I set it up locally. Thanks very much for your help! Hopefully they... -
Failed to Open Stream
Well, the problem still exists even if I use http to access the file I need (the files are stored both on FTP and HTTP). I also verified fopen is set to true. -
Failed to Open Stream
The free host I'm doing doesn't give me the option to SSH in. I'll give it a shot on my local machine and see what happens. -
Failed to Open Stream
Thanks for your reply. Unfortunately it isn't set to false. Someone else running a similar script is also having problems which is making me think it might be some sort of issue with the file server I'm accessing. Hmmm... -

Failed to Open Stream
All of a sudden I'm getting the following errors when trying to execute a script: Warning: fopen() [function.fopen]: connect() failed: Permission denied in /home/www/jmg498.freehostia.com/radar/crrdr.php on line 51 Warning... -
Arithmetic in PHP
Nevermind, figured it out! <?php if($temp > "271.16") { $ratio = 12+2*(271.16-$temp); } $ratio = 12+(271.16-$temp); print "The snow to liquid ratio is $ratio"; ?> This thread can be deleted. Thanks! -
Arithmetic in PHP
...on the code, but I just don't know how to format it correctly in PHP. Any help is GREATLY appreciated! :) $temp is a variable passed in by a form. <?php if($temp > "271.16") { $ratio == "12+2*(271.16-$temp)"; } $ratio == "12+(271.16-$temp)"; print "The snow to liquid ratio is $ratio"; ?>
