First Friday script updated and simplified

Chris Kankiewicz — Sun, 15 Feb 2009 02:40:04 +0000

NOTE: The latest version of this script can always be found here: http://github.com/PHLAK/first-friday/blob/master/first-friday.php

With this update I have drastically reduced and simpified the code to produce the same results. I did some rigorous testing of my own to make sure this script will calculate the correct date, but that doesn’t mean it’s bullet-proof. If you find a bug, please email me so I can fix it.

first-friday.php

 
  // Calculate next Friday
  for ($x = date('d'); $x &lt;= (date('d') + 6); $x++) {
    $timeStamp = mktime(0,0,0,date('m'),$x,date('Y'));
    if (date('w',$timeStamp) == 5) {
      $nextFriday = mktime(0,0,0,date('m'),$x,date('Y'));
    }
  }
  // Check if next Friday is the first friday of the month.
  if (date('d', $nextFriday) &lt;= 7) {
    $firstFriday = $nextFriday;
  } else {
  // Calculate first Friday of next month
    for ($x = 1; $x &lt;= 7; $x++) {
      $timeStamp = mktime(0,0,0,date('m')+1,$x,date('Y'));
      if (date('w',$timeStamp) == 5) {
        $firstFriday = mktime(0,0,0,date('m')+1,$x,date('Y'));
      }
    }
  }
 
  // Echo next first Friday
  echo date("F j, Y", $firstFriday);

Calculate the first Friday of next month with PHP

Chris Kankiewicz — Tue, 21 Oct 2008 05:50:40 +0000

UPDATE: This script has been updated, see: http://www.web-geek.net/posts/2009/02/14/first-friday-script-updated-and-simplified/

While developing phx2600.org, I ran into a slight dilemma. The PHX2600 meetings occur once a month on the first Friday of every month, and we wanted to display that on the site. However, it was becoming a tedious chore to change the date once a month manually. So, being the automation addict I am, I thought, why not write a script. So one night I hammered out the following script that will calculate the first Friday of next month:

  // START FUNCTIONS
 
  function get_day($describer,$weekday,$reference_date) { // $reference_date format = m-Y
 
    $d = explode('-',$reference_date);
 
    switch ($describer) {
      case 'first': $offset = get_day_offset($reference_date,$weekday); break;
    }
 
    $r = mktime(0,0,0,$d[0],1+$offset,$d[1]);
    return $r;  //returns timestamp format
  }
 
  function get_day_offset($anchor,$target) { //$anchor format = m-Y
 
    $ts = explode('-',$anchor);
    $ts = mktime(0,0,0,$ts[0],'01',$ts[1]);
 
    $anchor = date("w",$ts);
    $target = strtolower($target);
    $days = array(
      'sunday'=>0,
      'monday'=>1,
      'tuesday'=>2,
      'wednesday'=>3,
      'thursday'=>4,
      'friday'=>5,
      'saturday'=>6
    );
 
    $offset = $days[$target] - $anchor;
 
    if ($offset<0) $offset+=7;
 
    return $offset;  //returns 0-6 for use in get_day();
  }
 
  //END FUNCTIONS
 
  $t = getdate(); //Get today's date
 
  $today = date('m-Y',$t[0]); //Display today's date as MM-YYYY
 
  //Calculate Next Month
  if($t[mon] == '12'){
    $nm = '1-'.($t[year]+1);
  } elseif($t[mday] <= '7' && $t[wday] <= '5') {
    $nm = ($t[mon]).'-'.$t[year];
  }	else {
    $nm = ($t[mon]+1).'-'.$t[year];
  }
 
  $date = get_day("first", "friday", $nm);
 
  //Checks if today is after the first friday of the month
  if($t[mon] == date('m',$date)
    && $t[mday] > date('j',$date)
    && $t[mon] == '12') {
      $nm = '1-'.($t[year]+1);
      $ff = get_day("first", "friday", $nm);
  } elseif($t[mon] == date('m',$date)
    && $t[mday] > date('j',$date) && $t[mon] != '12') {
      $nm = ($t[mon]+1).'-'.$t[year];
      $ff = get_day("first","friday",$nm);
  }	else {
    $ff = $date;
  }
 
  // I know this code is crap, deal with it or fix it yourself!
 
  echo date("F j, Y", $ff);
 
?>

I apologies for the crappy code, I was either tired, drunk or both the night I wrote this.

IP Uploader – Python Script (.py)

Chris Kankiewicz — Tue, 30 Sep 2008 09:28:17 +0000

NOTE: This script can now be found here:: http://github.com/PHLAK/ip-uploader

This is my first python script I ever wrote. This script connects to whatismyip.com, fetches the external IP address of the network you are on, puts it into a text file and uploads it via FTP to any server you want.

At home I have Cox, therefore I have a dynamic IP. Even though this IP only changes about once every month, I got sick of needing to connect to my home computer via VNC and not being able because my IP had changed. Therefore I created the following script and set up a scheduled task on my home computer to run this script every hour.

After running this script, you can then use PHP (or any similar language) to include this file into any page you desire.

#! /usr/bin/env python
import httplib
import sys
import os
import ftplib
 
file="ip.txt"
 
conn = httplib.HTTPConnection("www.whatismyip.com")
conn.request("GET","/automation/n09230945.asp")
response = conn.getresponse()
data = response.read()
 
filename = str(os.path.abspath(os.path.dirname(sys.argv[0])) + "\\"+file) #Create file
FILE = open(filename,"w") #Open file ready for writing
FILE.writelines(data) #Write 'data' to file
FILE.close() #Close file
 
#Replace [server], [user], and [pass] with your information.
s = ftplib.FTP('[server]','[user]','[pass]') #Connect
f = open(file,'rb') #File to send
s.storbinary('STOR '+file, f) #Send the file
f.close() #Close file and FTP
s.quit() #Quit FTP
 
sys.exit(0)
